PURPOSE:To increase energy density by adding liquid absorbing fine powder and acid-resistant hollow fibers to a negative plate. CONSTITUTION:0.01-10wt.% liquid absorbing fine powder of at least one selected from the group of silicon oxide, aluminium oxide, titanium oxide, and carbon and 0.01-5.0wt.% acid-resistant hollow fibers 1 of at least one selected from the group of polyethylene, polypropylene, and polysulfone in which many holes 2 or grooves are passed through from the surface are added to a negative active material. The utilization of the negative active material is substantially increased, and high rate overcharge performance and energy density are improved. |
