FLOODED LEAD-ACID BATTERY |
摘要 |
A flooded lead-acid battery includes a negative active material, a positive active material having lead dioxide as a main component, and an electrolyte solution that contains sulfuric acid and is flowable. The negative active material of the flooded lead-acid battery contains carbon, a water-soluble polymer formed of a bisphenol condensation product having a sulfonic acid group, and a cellulose ether. The flooded lead-acid battery has low turbidity of the electrolyte solution and is excellent in high rate discharge performance at low temperature, regenerative charge accepting performance, and endurance performance in a partially charged state. |
