Rechargeable battery structure having a stacked structure of sequentially folded cells










Image Number 6 for United States Patent #6461762.

This specification discloses a rechargeable battery structure and the method of making the same. The battery comprises a stacked structure suitable for rectangular batteries by an S-shape sequential folding so as to increase the energy density and the charge/discharge cycle of the battery while lowering the safety worry about filling too much electrolyte. The feature of a stacked battery structure is that no active material of the positive and negative electrodes is coated at folded corners. The folded corner is also glued to make a thinner battery cell after squeezing under pressure. This folded cell is further under the application of heat and pressure and put into a rectangular battery case made of metal or aluminum foil. A new battery structure is thus obtained after filling electrolyte and encapsulation.
