A mobile phone heat dissipation aluminum case lithium-ion battery

Abstract

The invention belongs to the technical field of new energy batteries, and specifically refers to a lithium-ion battery with a heat-dissipating aluminum case for mobile phones, which includes an aluminum case and an alumina ceramic inner case, an alumina ceramic layer is provided on the inner wall of the aluminum case, and an alumina ceramic inner case There is a battery body, a cooling cavity is formed between the aluminum outer shell and the alumina ceramic inner shell, and the cooling cavity is filled with cooling liquid. A number of alumina ceramic heat dissipation pipes are installed on the battery body, and the two ends of the alumina ceramic heat dissipation pipe are connected to the The alumina ceramic inner shell is connected, and the alumina ceramic heat dissipation pipe communicates with the cooling cavity. The heat generated during the charging and discharging process of the present invention is transferred to the cold starved liquid, and the temperature of the cold starved liquid rises after absorbing the heat, and then flows and transfers the heat to the aluminum shell in time, and the aluminum shell dissipates the heat to the outside, effectively dissipating heat, and making the battery at the proper working temperature.

Description

technical field [0001] The invention belongs to the technical field of new energy batteries, and specifically refers to a lithium-ion battery with a heat-dissipating aluminum case for a mobile phone. Background technique [0002] A lithium-ion battery is a rechargeable battery that primarily relies on the movement of lithium ions between the positive and negative electrodes to function. Lithium-ion batteries use carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. There is no lithium metal, only lithium ions. This is the lithium-ion battery and is a representative of modern high-performance batteries. [0003] Compared with traditional lead-acid batteries, lithium batteries have obvious advantages, such as higher energy ratio, longer service life, higher rated voltage, lower self-discharge rate, lighter weight, more energy-saving and environmental protection, and many advantages Lithium-ion batteries are widely used, especia...

AI Technical Summary

Problems solved by technology

However, during the charging and discharging process of lithium-ion batteries, a large amount of heat will be generated, which will cause the temperature of the battery to rise. If the temperature is too high, it will affect the performance of the battery, and the service life of the battery itself will be significantly shortened. Normal use will be affected, and serious cases will cause safety hazards

[0004] The aluminum-cased lithium-ion battery used in existing mobile phones cannot dissipate heat well during use, which often leads to high battery temperature, which affects battery performance and service life, and also affects the normal use of mobile phones. In severe cases, it may lead to potential safety hazards
