have developed an inexpensive sensor that can warn of impending catastrophic failure from thermal runaway in lithium-ion batteries. The sensor is based on the researchers’ discovery of an intrinsic relationship between the internal temperature of lithium-ion cells and an easily measured electrical parameter of the cell.

will soon start producing electrolytes for lithium-ion batteries, initially at its Daikin America plant in Alabama, and begin selling them in January. Nikkei. Japan-based Daikin Industries Ltd. Daikin says its product can be charged at higher voltages than conventional electrolytes, helping to lift battery capacity by 20%. Brief
