6-SPB Series Spiral Lead-Carbon Battery

The Spiral Lead-Carbon Battery is a recent development of Shoto Group. The most advanced composite carbon material is introduced, therefore, the electrical conductivity and the specic surface area of negative active material are improved and a continuous conductive network is established; Finally, the sulfation are signicantly improved, the PSOC cycle life are greatly extended. With the unique winding structure, high assembly pressure and valve opening pressure , the battery’s dehydration is greatly reduced. Compared to ordinary battery, the battery has superior high-low temperature performance and high rate discharge performance, especially the security and fast charging performance are outstanding. The product is protected by ve patents namely: 02112897.9, 03152809.0, 03221098.1, 00310112676.1,200510040205.3
