METHOD FOR PRODUCING POSITIVE PLATE OF Li/SOCl SYSTEM CELL Russian patent published in 2005 - IPC

FIELD: electrical engineering; manufacture of positive plates for lithium chemical current supplies.

SUBSTANCE: proposed method for manufacturing positive plate of Li/SOCL₂ cell includes rolling of cathodic material composed of mixture of powdered nickel, carbon black, and binder followed by sintering; prior to preparation of cathodic material powdered nickel introduced in the latter is treated with HNO₃ solution of 40 - 60% concentration for 2 - 5 min, rinsed with distilled water, then dried out under vacuum of -100 kPa at temperature of (70 ± 5) °C for 2 - 3 h, and upon plate sintering cell is given charge-discharge cycling by passing current pulse through it.

EFFECT: enhanced power characteristics and safety of cell.
