Abstract
Disclosed herein are a high power lithium unit cell and a high power lithium battery pack having the high power lithium unit cell. The present invention increases the width of an electrode terminal of a lithium battery, thus reducing heat generation and a potential drop due to resistance of the electrode terminal, therefore efficiently eliminating the generated heat.
Claims13
A high power lithium unit cell, comprising:
- at least one rectangular anode plate having an anode collector, at least one surface of the anode collector being coated with an active material of anode;
- at least one rectangular cathode plate having a cathode collector, at least one surface of the cathode collector being coated with an active material of cathode;
- at least one separation film inserted between the rectangular anode plate and the rectangular cathode plate, and providing electric insulation;
- an anode terminal connected to an anode plate connecting part which protrudes from either of two long sides of four sides of the rectangular anode plate;
- and
- a cathode terminal connected to a cathode plate connecting part which protrudes from either of two long sides of four sides of the rectangular cathode plate.

A high power lithium battery pack, comprising:
- at least one high power lithium unit cell, comprising:
- at least one rectangular anode plate, separation film, and rectangular cathode plate sequentially laminated;
- an anode terminal extending outwards from either of two long sides of four sides of the rectangular anode plate;
- and
- a cathode terminal extending outwards from either of two long sides of four sides of the rectangular cathode plate;
- at least two gaskets laminated on both surfaces of the high power lithium unit cell;
