ELECTRODE FOR STORAGE BATTERY WITH NONAQUEOUS ELECTROLYTE Russian patent published in 2002 - IPC

FIELD: electrical engineering. SUBSTANCE: electrode has active material, electricity conducting dope, and binder. Active material Li_xNi_yM_zO₂(0,8<x<1,5, 0,8<y+z<1,2, 0≤z<0,35;; M is at least one element chosen from group of Co, Mg, Ca, Sr, Al, Mn, Fe) whose particles are of average diameter ranging between 2.0 and 50 mcm estimated by width of distribution curve of particles according to their size through half their height. Binder is, essentially, fluorine rubber or polyvinylidene fluoride. Electricity conducting dope is graphite when polyvinylidene fluoride is used as binder. EFFECT: enhanced battery capacity and electrode flexibility. 2 cl, 1 dwg, 3 tbl, 3 ex
