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

Abstract
A lithium-ion soft battery which can maintain within a certain range includes a battery cell having a positive electrode plate and a negative electrode plate. The negative electrode plate includes a negative current collector and a negative active material layer on the negative current collector. The positive electrode plate includes a positive current collector and a positive active material layer on the positive current collector. The positive electrode plate and/or the negative electrode plate includes a heat conducting and collecting body, which is a portion of the positive current collector not coated by the positive active material layer or a portion of the negative current collector 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. A fluid-containing pipe is connected to the heat converging path.
