Expert: Li-ion battery problems are many reasons

Continued violence on the defects in the notebook lithium batteries(hp f2024b battery,hp f4486b battery,hp f4809a), Dell, Apple recall the news of a large scale after a few days ago and reported that Matsushita is recalling in Japan of the 6000 domestic sales of notebook lithium batteries due to overheating because there is also a hidden danger .
Although the Panasonic than the size of the battery before the recall of Dell and Apple more than the size of a small, but had to let us look at the notebook again the safety of lithium batteries. In this regard, lithium-ion battery industry experts said Steven Carlson, lithium batteries are not due to frequent problems with lithium batteries due to its own technology, its causes should be multi-faceted.
With the continuous development of notebook computers, the battery life of notebook also a higher demand, which makes the manufacturer is faced with enormous challenges. Reason for the accident, Carlson said the main reason for this is because the manufacturer of the battery due to the requirements of the standard.
For the needs of consumers, battery manufacturers have to come up with a long product life, but at the same time ensure the safety of products, reduce heat, and to consider its own manufacturing costs, which is currently faced by manufacturers problems. Carlson said that as the temperature exceeds the tolerance range of the hp f4812a battery,hp hstnn-lb31 battery itself, the lithium batteries will enable the “Auto-off” technology to prevent the fire, so the battery is not unexpected technical reasons.

Battery life hanging security technology

To the small volume of high-capacity road
Battery exploded, who is responsible? Blame technology or the authority to ensure the technology? And put this issue off.
As early as the end of August the company announced that Apple Computer recalled 1.8 million Sony-made lithium-ion notebook computer batteries, and 10 days ago Dell to recall 4.1 million notebook batteries before. Nickel-metal hydride battery technology with its batteries unstable chemicals caused the explosion had not only with the people’s attention in the safety of the notebook battery when I, we questioned whether or not the lithium battery materials as a safety?
Lithium had no security
Experts say, because lithium is a very active chemical element, in an instant easy to fire damage outside the blast. For example, when the notebook on the bed, poor ventilation, the temperature is getting higher and higher, causing a chain reaction.
Why do we rarely heard of battery explosion, and this year more and more frequent occurrences of such incidents? This is the work by the principle of lithium batteries caused by unit volume in order to save more power (lithium battery technology than Ni-MH hp 372772-001 battery,hp 398876-001 battery,hp 417066-001 storage 30% to more than 200 percent), manufacturers out of the Ni-MH / Ni-Cd battery switch to the chemical nature of instability as a lithium-ion energy storage medium; Once outside the production of industrial or defective, the lithium battery explosion heat more easily.
During the last century about 80 laptops are most applicable to NI-CD Ni-Cd batteries, but batteries using this technology was too big and the small battery capacity, a shorter life-span, heavy weight disadvantage and so on, making lithium batteries soon widely used by manufacturers.
In fact, the use of lithium batteries in the early days, often when in charge combustion, the bursting of the situation. Later there will be a improved version of the lithium-ion batteries by adding the element lithium can inhibit the active ingredients, so that the real power of lithium to achieve a safe, efficient, convenient, and the old lithium also eliminated. As to how to distinguish them from the logo on the battery will be able to identify, lithium power for LI, lithium-ion battery for LI-ION.
Safety depends on production technology
Principles of lithium batteries as a result of instability, so the demands on the production process more stringent! Today, frequent accidents, firms in the manufacturing sectors of controlled technology will lead to a slight security issues.
It is understood that the fire resulted in Sony’s lithium-ion hp 346970-001 battery,hp 367759-001 battery,hp f2024a explosion, that is, during the manufacturing process because the batteries into a small metal particles caused by; Panasonic notebook battery recall (non-Sony-made) is also due to manufacturing defects, have leakage, heating, deformation, and even the danger of fire. The lithium batteries because of the domestic cell phone manufacturing process issues, have also taken place in a number of security incidents.
Internal batteries and battery protection circuit board battery safety has become the main location of the occurrence. At present, the main origin of the batteries in Japan, Korea, in particular, mostly in Japan. Comparison of well-known of which is Japan’s Sanyo (Sanyo), South Korea’s LG, Samsung and so on.
Subject to product miniaturization
Expert told reporters that the miniaturization of electronic products is currently the trend of more and more obvious, not just notebooks, including the mobile phone, PDA, handheld game devices and so on continuously to the miniaturization of challenges, the complexity of the natural features also increase the battery capacity, Although lithium-ion battery than nickel-cadmium battery NI-CD small size, large capacity, but the future will undoubtedly give way to a new generation of methane fuel cell technology.
Experts said that the future of the same size of fuel cell capacity to achieve more than 10 hours, and is currently used lithium notebook battery up to 5 hours continuous use. Methane fuel cells, however than the safety of lithium batteries are more at risk. Itself toxic methane, has always been highly volatile, flammable liquid. Case of heat, open flame or fire-oxidants easy. Case of fire explode.
Experts said that the improvement of battery technology is always accompanied by the improvement of the risk coefficient, which has been difficult to escape. Only batteries within the unit volume of chemical substances in the more active, larger battery capacity can be improved.
In fact, the birth of the fuel cell more than 100 years, but has not been able to solve security issues. Toshiba products including the most recent use of fuel-cell notebook, he was unable to solve the battery as a supplement methane energy technology, such as how to bring security issues.
