3G battery terminals to become the bottleneck

Recently, the energy industry in the 3C become a hot topic, and this topic is also important in the mobile phone, mobile phones and mobile phone dell inspiron 640m battery,dell inspiron 700m battery capacity of the energy-saving technologies to develop mobile phone has now become a “invisible injury.”

This year, the color screen mobile phones have occupied a leading market position, and camera phones, multimedia phones, etc. The emergence of new mobile phones more and more camera functions, send and receive multimedia messages, download games feature high-capacity utilization rate of the more to the higher, and the use of these features let a marked increase in the frequency of charging, cell phone batteries are increasingly overwhelmed, mobile phone battery capacity has also become a mobile phone battery manufacturers and manufacturers of a major research topic.

More than half of that satisfied the battery failed

China’s mobile communication industry, rapid growth, especially the rapid growth of the cell phone market, mobile phone batteries made by the industry more and more general concern of all parties. However, with the emergence of color screen mobile phone, users are increasingly less than the battery capacity of mobile phone battery has decreased satisfaction. Users a color screen said: “buy color, camera phone is to follow the trend, if the charge for mobile phones every day and hectic, but life back.”

Not long ago, a survey said that 79% of users of mobile phone batteries have different views, mainly of standby time, the three aspects of performance and appearance. Of which 37% of respondents feel that mobile phone battery standby time is too short, day-to-day use to keep charging, and business travel is also very inconvenient; there are nearly 20% of people feel that color in the overall mobile phone battery can not meet the color letter, chords, photographs, Bluetooth, games and other multimedia needs. Mobile phone users, according to color, the Treasury in the absence of words or short message, the color screen cell phone standby time is generally 4 days, the actual use is generally 1 to 2 days, there are users that need to phone every day charge in order to ensure the normal use of mobile phones.

The development of mobile phones and dell inspiron 710m battery,dell inspiron 8500 battery are not synchronized

Frequently on the cell phone manufacturers to launch multimedia handsets, mobile phone users generally feel that the standby time greatly shortened, which is due to color screen cell phones now, taking pictures, MMS, GPRS Internet access and other functions of the electricity costs are very high, at the same time, cell phones more compact shape, thin, mobile phones have also reduced the size of the battery, resulting in color screen mobile phones, most are faced with a small battery capacity, standby, the problem of a shorter talk time. Insiders said that in the mobile phone features, shape is continuously progressing, the battery capacity of mobile phones has failed to demand functions such as development, which is no doubt breaking the current high-performance electronic devices, the use of time and the battery weight balance among the three.

Now, if battery technology can not maintain the volume unchanged weight of a substantial increase in the volume of energy storage is not high-profile battery is likely to delay the pace of mobile communications. Therefore how to raise the issue of energy storage, high-performance electronic equipment re-use of time and battery to achieve a balance weight, as the challenges and opportunities manufacturers.

3G mobile phone battery terminals to become the bottleneck

Although 3G technology research and testing carried out in an orderly manner, but 3G and Wi-Fi mobile communications brought about by some commercial applications but can not wait. Because the long-awaited 3G, is now ready to make the Wi-Fi technology, they are running non-stop connection in case of network and wireless data communication applications accompanied by the emergence of large-screen color and large-capacity memory in the provision of high-quality applications, but also a lot of power consumption. If the battery technology can not maintain the volume unchanged weight of a substantial increase in energy storage, the battery is not eye-catching are very likely to be the first 3G hind legs dragging.

According to the MII said, and now 3G network and the application of the end product there is a gap, 3G handsets and widespread interoperability of the problem of not enough battery power. 3G provides a high-speed multimedia handset, but in the actual application of 3G today the capacity of lithium-ion batteries seem unable to, a number of 3G mobile phone features in the use of video in about an hour to run out of cell phone battery, which is obviously not suitable for indoors outside the mobile use, this is some mobile phone manufacturers to postpone the main reason for the introduction of 3G mobile phones.

Cell technology to “running”

In recent years, as computing speed and improve the functions, communication terminal equipment in the pursuit of high-performance computing and multimedia communications and color at the same time, with high power consumption has become difficult to climb obstacles. With the increase of wireless data applications, mobile and battery more prominent contradictions durability, power is simply not destined to go, and how to break through technical barriers to the dell inspiron 6400 battery,dell inspiron 640m battery itself, scientists have applied to become a hot research topic with each other.

Faced with this problem, many cell phone manufacturers are developing new mobile phone batteries to meet power demand. Including solar cells, zinc-air batteries, fuel cells, but according to Kim Tong TCL cells expressed an engineer for a fairly long period of time, the availability of these new type of battery is very low and business, cell phone battery is also the protagonist in the field of will be lithium-ion battery.

According to professionals, said cell phones now than before lithium-ion batteries for nearly 30 percent raise, but it can not meet the needs of technology development, as more and more compact cell phone, multifunction, large color screen, the further development of the space reserved for the battery the smaller, but also have higher energy requirements. On the current materials used in lithium batteries, the energy density there is about 20% of the development of space, which is now a focus of research and development firms, I believe that within the next two years can not be a new chemical materials in the batteries, lithium-ion battery will play a leading role.

Looking at the 3G industry is now in all areas of products, supplies equipment and notebooks, television sets, refrigerators and air-conditioning in the development of energy-saving technology, power-saving new features and new products. The mobile phone industry, now power mobile phones in use in general can not satisfy user needs, to the era of 3G mobile phones have become a power capacity of the application together with a higher threshold, but in the mobile phone technology itself has no associated energy conservation, saving the technology appear phone battery at the same time also failed to meet the requirements of 3G applications. Thus, the capacity of mobile phone batteries are now in great need to increase the density of the stage, the battery technology to “running” at the same time, cell phone itself should also consider how to develop a number of energy-efficient power-saving technology, a fundamental cell phone use to meet the demand for energy-saving in order to cope with mobile phone features high-speed development.

Breakdown of cell phone family history

Nickel-type batteries will have served its purpose

Nickel-cadmium battery and durable due to the benefits of affordable, products for the global mobile phone market “off to a good start” made a contribution. Its greatest disadvantage is that it must wait until the complete exhaustion of battery power to re-charge, and charge must be completely filled, otherwise the capacity of the battery storage of electricity will not be able to play to the maximum.

After the nickel-metal hydride batteries came into being. It is not only the same as with the nickel-cadmium batteries with a durable and low-cost advantages of these two, and it can be recharged at any time, in the same volume and weight, the Ni-MH battery capacity than the nickel-cadmium battery much, he won the favor of users .

Lithium-ion battery Time

The same energy output, the weight of lithium-ion battery not only lighter than the nickel-hydrogen batteries half, 20 percent of small size also. In addition, the rechargeable lithium-ion battery faster, requires only 12 hours of electricity will be sufficient enough to reach the best condition; At the same time, the volume of lithium-ion dell inspiron 700m battery,dell inspiron 710m battery leakage minimal, even if it put in a drawer a few weeks, when you out with, it can play the same as the operation of power as usual. The most important thing is that lithium-ion batteries in this unique advantages of small size, only a portable cell phone is now possible.

The future of fuel cell energy

As early as two years ago, the Japanese electronic company developed for a long time the use of mobile phone fuel cell in order to resolve the current mobile phones available in the market a shorter battery life problems. This fuel cell is no longer the need to charge, only to add fuel, through the reaction of hydrogen and oxygen to generate electrical energy can be.

In fact, the German enterprise has developed a SmartFuelCell methanol battery production equipment, the initial sample. The new battery will be the capacity of ordinary lithium batteries 10 times, which means that users of existing models of mobile phones could be a month without charge. The use of 3G mobile phones than the average frequency is much higher, so 3G mobile phone fuel cell may be the biggest beneficiary.

Zinc-air batteries and the lowest sound

Zinc-air battery would be desirable to use the air everywhere as an important cell phone battery raw materials, while the lowest is a sound ideal replacement product type. In these cells, not only to reduce production costs, and can effectively solve the pollution problem in the battery. Compared with conventional batteries, and its higher energy, lower cost, longer life can be. “Magic” battery “and” mobile phone radiation.

A high-tech companies in the United States late last year launched a mobile phone battery, to a certain extent, reduce cell phone radiation affects the human body. This mobile phone battery EMFBiochip called because there is a special on-chip (circuit board), so the phone can detect radiation and produce a “random” radiation, mobile phone radiation “and.”

30 seconds of the new battery charger

NEC has developed in a short time a new battery charger, charging time of 1 hours from now on shortened to 30 seconds or so for portable MD players and digital cameras, people will bring more convenience. According to reports, the development of the dell inspiron 8500 battery is meant by “organic radical battery,” a special kind of resin used storage, NEC Corporation made two models, one is 2 centimeters square, 4 mm thick, a card like the same size, 5 mm thick, the charging time of 30 seconds for portable MD players can play 80 hours straight, and with models of nickel-hydrogen batteries roughly the same performance, but save a lot of charge time for the portable electrical products there are broad prospects for .

U.S. scientists develop a low-cost plastic solar cells

University of California, Los Angeles Campus (UCLA) researchers have developed a low-cost plastic solar cells, solar cells that will be the production cost of traditional solar cell production costs by 10% ~ 20%. At present nearly 90% of the solar cells are made from silicon, and from UCLA to develop solar cells dell inspiron 5160 battery,dell inspiron 6000 battery is between two conductive pole holding a plastic composed of single-layer. UCLA engineering professor Yang Yang pointed out that such a solar cell conversion efficiency of 4.4%, which is far the world’s highest conversion efficiency of plastic solar cells. The conversion efficiency of solar cells to absorb all the radiation refers to the surface in the percentage of total energy.

According to UCLA, said the performance of plastic solar cells is the ultimate goal of conversion efficiency reached about 15% to 20%, and the use of period 15 ~ 20 years. As for the traditional large-scale solar cells for use in the same period of the conversion efficiency of 14% ~ 18%.

Make greater efforts to develop fuel cell industry

Battery is the key to buy mobile products

In the near future Sina IT168 website and a joint investigation of the laptop showed that nearly 50% of the users to “extend notebook battery life” issues as a first choice. The manufacturers usually focus on what the recommended hard disk transfer rate of 5400, 1394, Bluetooth, 802.11 wireless, Gigabit LAN what, but all in a simple “battery life” behind.

This has given the answer to the so-called experts have a lot of the glasses below. Why is there such a result?

For desktops, the performance may be the vitality of the host desktop; As for notebook computers, the battery life is the life of notebook computer power. Simply consider the configuration of the desktop experience in a notebook is no longer fit the times might have been.

ASUS has been with leading motherboard manufacturers, such as technology, as well as a number of notebook Power4Gear industry-leading power technologies, M2N its new products in the standard configuration has been reached in 7.4 hours time. During the interview, ASUS engineers said that many manufacturers currently on the market are always in the promotional products advertised high configuration, in fact, these are induced by a non-comprehensive. In actual use, the same configuration, the performance of notebook computers will not be stronger than the desktop, if the pursuit of simple configuration options so not as good as the desktop. From practical applications, the notebook computer from the desktop should be the biggest advantage of portable and mobile. Based on this principle, ASUS laptop in the design to take into account the two most important factors is the “thin and light portable and lasting power.” A lack of long-lasting battery life of notebook computer capacity, it is impossible to take a long time the needs of mobile applications. And the lack of dell inspiron 5150 battery,dell inspiron 5160 battery power of notebook computers to help, and naturally the most fundamental lack of vitality.

It is based on a unique application of notebook computers fully into account, it always insists on ASUS notebooks focus on the power-saving technology to do one of the technological development. Currently, Asustek’s notebook computers are basically used Power4Gear original ASUS power switching technology. The technology uses a microprocessor and a number of deep-sleep standby set performance greatly enhanced notebook PC features the use of elastic energy.

From the development of notebook computers, the Centrino technology is the future direction of the development of notebook computers. And to provide more long-term Centrino technology is the use of the time one of the key points of concern. According to Intel Centrino in the time of the promotion of a survey conducted by the current users of notebook computers to provide wireless connectivity and more time using the most concern. In more time, how to reduce the notebook’s power consumption, increased use of mobile computing time for those who are even more important. In fact, both the practical applications of notebook computers or the future direction of development, we can no exaggeration to say that the battery life of notebook computers is the driving force. Notebooks should be to ensure that the basis of a lasting power to provide dell inspiron 6000 battery,dell inspiron 630m battery the most suitable applications.
