Electrochemical performance of nanocrystalline lead oxide in VRLA batteries

摘要

Nanocrystalline lead oxide was prepared through two-step chemical reactions and has been tested as the electrode active material for the valve-regulated lead acid (VRLA) battery. By using this nanocrystalline lead oxide, the pasted electrodes can be directly formatted without a curing process. The initial specific capacity of the new electrode was 30 percent higher than that of the electrode with the conventional ball-milled leady oxide and the cycle behaviour of the new electrode was also improved.
