Claims16
A rechargeable battery comprising:
- an electrode assembly having a positive electrode, a negative electrode, and a separator between the positive electrode and the negative electrode, the electrode assembly having at least one rounded side;
- a case for housing the electrode assembly;
- and
- at least one spacer in the case, the at least one spacer having a plurality of through holes in communication with the at least one rounded side and adapted to permit electrolyte flow, and an arch shaped groove adapted to mate with the at least one rounded side, wherein the at least one spacer occupies substantially an entire space between the case and the at least one rounded side of the electrode assembly.
