LITHIUM CELL Russian patent published in 2003 - IPC

FIELD: electrical engineering, chemical sources of electric energy. SUBSTANCE: in accordance with invention lithium cell is equipped with additional sealed lead-out placed on housing connected to nickel membrane coming in the form of gauze with cell size (80-120) x (80-120) mcm. Presence of sealed lead-out connected to membrane on housing makes it feasible to record changes of membrane potential at moment of dendrite growing through separator and makes external influence on lithium dendrite possible ( for example, its automatic burn-out by heavy current or dissolution with discharge ). EFFECT: raised safety while handling lithium cells and preservation of high specific characteristics. 1 tbl
