Abstract
A sealed tubular lead-acid battery is provided which offers high-rate discharging performance and long cycle life by loading granules of fine particles of silicon dioxide both in a gap between a separator and around each of a positive and negative plate, as well as around the assembled element comprising a separator and the plates. An electrolyte is retained on the positive plate, the negative plate, the separator, and the granules of fine silicon dioxide particles.
