MH-Ni电池封口化成及其性能
English
The Sealed Formation and Performances of MH-Ni Batteries
Abstract:
The performances such as the discharge capacity, activation, electrocatalytic activity and high-rate dischargeability of MH electrodes were improved by the chemical reduction in an alkaline solution containing a reductant KBH4. MH-Ni batteries assembled with KBH4-treated MH electrodes as negative electrodes were sealed formated. The performances of the batteries by sealed formation were superior to that of the batteries by open formation. The capacity approached 1150 mAh. High-rate dischargeability (at 5 C) was above 80% and the capacity at -18℃ (0.2 C) was 90% of that at room tempearture (0.2 C). The cyclic life of the MH-Ni battery at 1 C (100% DOD) increased from 100 cycles to 200 cycles and more.
