Structure laminated unit cells for lithium polymer battery of high power.

摘要

A battery system, comprising first and second unit cells (31a, 31b) having, each, a bag (34) and terminals (32a, 33a; 33b, 32b) of anode and cathode, which are connected to a surface of the bag and are bent oppositely in upward and downward, wherein the cathode terminal of the second unit cell (31b) is directly connected to the anode terminal of the first unit cell (31a) and characterized in that the parts (35) of connection between the terminal (32a, 33b) of the anode and the bag (34) and between the terminal (32b, 33a) of the cathode and the bag (34) are staggered.
