Here are some new testings (overcharge) of Li-ion polymer batteries
Well-dispersed bi-component-active CoO/CoFe2O4 nanocomposites with tunable performances as anode materials for lithium-ion batteries : Chem. Commun. , 2012, Advance Article DOI : 10.1039/C1CC15322F, Communication Meixia Li, Ya-Xia Yin, Congju Li, Fazhi Zhang, Li-Jun Wan, Sailong Xu, David G.

Polypore’s Celgard Files Suit Against Sumitomo Over Batteries - Bloomberg : "" The complaint, filed Feb. 22 in federal court in Charlotte, North Carolina, claims Sumitomo is infringing a patent issued in 2002 for a separator in high-energy rechargeable batteries. The separators prevent short circuits that can reduce efficiency and limit safety problems from overheating. (Via Bloomberg .)
Sumitomo earlier reported that it has achieved energy densities as high as 290 Wh/L with the new battery. A drawback to the general class of molten salt batteries (e.g., the ZEBRA battery , or GE’s Durathon sodium-metal halide batteries, earlier post) has been the need for high operating temperatures to keep the salt molten. Being non-volatile and non-flammable , and with high ion concentrations, molten salt makes an excellent battery electrolyte and can offer high energy and power densities. In a joint project with Kyoto University , Sumitomo developed a molten salt with a melting point as low as 57 °C. Using this salt, it developed the new molten-salt electrolyte battery. Since it comprises only nonflammable materials, the new battery will not ignite on contact with air from outside, nor is there thermal runaway from overcharging or temperature rises in the battery. For this reason, Sumitomo says, there is no need for waste-heat storage or fire- and explosion-proof equipment, so ...
