BATTERY PACK AND TOROIDAL BATTERY CELL TO BE USED THEREFOR |
摘要 |
An assembled battery with a high capacity, comprising a plurality of unit cells electrically connected with one another in parallel, the unit cells each having a through-hole and being of toroidal shape, and the plurality of unit cells are arranged in a nested manner such that one unit cell is disposed within another unit cell. The problem that toroidal batteries with high capacity, high power density and small thickness may have a large volume and low energy density is solved by connecting in parallel a plurality of unit cells nested within one another, and heat dissipation of the battery is also further improved. A toroidal cell having heat dissipating fins is also provided. |
