Abstract

This utility model discloses a novel soft-pack lithium-ion battery pack structure, including a soft-pack lithium-ion cell, a positive electrode circuit board, and a negative electrode protection plate. The positive electrode circuit board includes a positive terminal, a first negative electrode conductive sheet, a first positive electrode conductive sheet, and a positive electrode plate. The negative electrode protection plate includes a second negative electrode conductive sheet, a third negative electrode conductive sheet, a negative electrode output terminal, and a negative electrode plate. The positive electrode circuit board and the negative electrode protection plate are respectively insulatedly disposed on the top and bottom of the cell body. The positive electrode tab at the top of the cell body is connected to the first positive electrode conductive sheet on the positive electrode circuit board. The negative electrode tab at the bottom of the cell body is connected to the second positive electrode conductive sheet on the negative electrode protection plate. The first negative electrode conductive sheet on the positive electrode circuit board is connected to the second negative electrode conductive sheet on the negative electrode protection plate via a conductive strip. Insulating tape is disposed between the side wall of the cell body and the conductive strip. This utility model has the advantages of convenient disassembly and installation, and can be easily installed into or removed from the battery compartment of portable devices.
