VALVE-REGULATED LEAD-ACID BATTERY |
摘要 |
In a valve-regulated lead-acid battery in which charging is performed intermittently on every short time and high rate discharging to a load is performed in a partial state of charge (PSOC), a valve-regulated lead-acid battery improved for the charge acceptance and the life characteristic under PSOC than usual is provided. A positive electrode plate having a specific surface area of an active material of 5.5 m 2 /g or more is used. A valve-regulated lead-acid battery is manufactured by using a negative electrode plate improved for the charge acceptance and the life performance by adding a carbonaceous electroconductive material and a formaldehyde condensate of bisphenols aminobenzene sulfonic acid to a negative electrode active material and setting the specific gravity of an electrolyte to 1.30 or more and 1.35 or less. |
