LITHIUM-ION POWER BATTERY
First Claim
1. A lithium-ion power battery comprising:
- a battery cell comprising a positive electrode plate and a negative electrode plate, the positive electrode plate comprising a positive current collector and a positive active material layer coated on the positive current collector, the negative electrode plate comprising a negative current collector and a negative active material layer coated on the negative current collector;
wherein at least one of the positive electrode plate and the negative electrode plate comprises two heat conducting and collecting bodies, each of the heat conducting and collecting bodies is a portion of the positive current collector which is not coated by the positive active material layer or a portion of the negative current collector which is not coated by the negative active material layer, at least two heat conducting and collecting bodies are stacked together to form at least one heat converging path, which is configured to transmit heat energy into or out of the battery cell, an insulating element is connected to the at least one heat converging path.

Abstract
A lithium-ion power battery includes a battery cell including positive and negative electrode plates. The positive electrode plate includes a positive current collector and a positive active material layer coated on the positive current collector. The negative electrode plate includes a negative current collector and a negative active material layer coated on the negative current collector. At least one of the positive and negative electrode plates includes a heat conducting and collecting body which is a portion of the current collector not coated by the active material layer. At least two heat conducting and collecting bodies are stacked together to form at least one heat converging path, which allows heat energy to enter or exit from the battery cell. An insulating element is connected to the at least one heat converging path.
