Název v původním jazyce

SAFETY OF LITHIUM BATTERIES

Popis výsledku v původním jazyce

Charge managing device is important for safety of lithium batteries. It means an electronic monitoring of each cell in the battery from viewpoints of overcharging, overload, overdischarging and occasional increase of temperature inside any cell. Anotherapproach is based on the selection of functional materials, which can maintain the capacity of the cells and ensure higher fire resistance of them. Lithium cell contains positive electrode, negative electrode and electrolyte. Improvement of LiCoO2 stability by doping with potassium ions and modification of spinel ? like LiFePO4 were tested as materials for anodes, while electrodeposition od silicon was verified for production anode materials with enhanced safety and capacity. Both the solvents and polymers were investigated as components of electrolyte. High thermal stability of sulfolane seems to be useful. Some aspects of treating and possible recycling of used batteries are discussed.
