Li-ion battery electrolyte additive non-combustible
Bridgestone (Bridge Stone) announced the development of a new type of additives, the additives can not affect the battery performance at the premise in the use of products such as cell phone lithium battery electrolyte into a non-combustible. Although lithium batteries with lead-acid batteries and nickel-hydrogen batteries have a quality compared to the advantages of high energy density, but because of electrolyte used in the flammability of organic solvents, and therefore improve thinkpad t41 battery, thinkpad t42 battery capacity and electric drive vehicles used in areas such as the existence of a fire or broken such as security issues.
Previously the company has also tried to enable the development of non-combustible electrolyte additives, but because of the battery cause performance degradation, it is not in practical use. The development of additives from Bridgestone "Hoslight (transliteration)" are from a phosphorus and nitrogen as the basic material Triazene phosphorus (Phosphazene) posed by the material, as additives, as long as the added electrolyte at 5 ~ 10% could have a flame retardant, as well as the effect of non-flammability. The additives also inhibit the cell response to internal heating effects.
Bridgestone is currently being provided to the thinkpad r50 battery, thinkpad r51 battery manufacturers of industrial samples for evaluation. The company is planning to determine the utility of the year period, from 2003 to begin test sales of battery manufacturers. The company is expected to achieve in 2005 at 10 billion yen turnover.
