Title: Clad type sealed lead-acid battery
Inventor: SHIOMI MASAAKI
IPC: H01M4/14
Filed: 1989-11-20
Abstract: PURPOSE:To increase discharge capacity and cycle life by specifying the amount of PbSO4 existing in the positive active material of a clad type positive plate before formation. CONSTITUTION:In a gel type sealed lead-acid battery in which a non-formed clad type plate is used as the positive plate, then formation is conducted within a container, the ratio of PbSO4 in the non-formed positive plate is specified to 20% or less to increase discharge capacity and cycle life. Discharge test was conducted with samples in which the amount of PbSO4 was varied. Batteries B and C containing 5% and 10% PbSO4 in their positive plates before formation showed high performance. Batteries having smaller PbSO4 content in their positive plates before formation showed longer life. This means that less stratification of an electrolyte gives uniform charge-discharge to positive and negative active materials.
