Battery provided with protective layer and protective layer thereof

Abstract

The invention discloses a protective layer for a battery. The protective layer is arranged on the surface of the battery or the outer packaging of the battery. The protective layer is closely attached to the surface of the battery or the outer packaging of the battery to seal the battery. The protective layer is a hard layer or soft layer, the protective layer is provided with a temperature regulating device. Several temperature-regulating channels are arranged inside the protective layer, and the temperature-regulating channels are provided with inlets and outlets, and the temperature-regulating device is composed of the temperature-regulating channels.

Description

technical field [0001] The invention relates to a battery provided with a protective layer, in particular to the structure of the protective layer on the outer surface of the battery. The protective layer seals and protects the battery and can play the role of impact resistance, corrosion resistance, pressure resistance, and vacuum resistance. Through the protection The layer can also regulate the operating temperature of the battery. Background technique [0002] At present, batteries are used more and more widely in various automation equipment and electronic equipment, for example, lithium-ion batteries are used as power sources. However, the battery itself has requirements for the use environment. It must avoid impact and pressure resistance, and has anti-corrosion and waterproof properties. Otherwise, it will damage its own structure and lose the power storage and discharge functions. Low average will affect the performance of the battery. [0003] In some special env...

AI Technical Summary

Problems solved by technology

However, the battery itself has requirements for the use environment. It must avoid impact and pressure resistance, and has anti-corrosion and waterproof properties. Otherwise, it will damage its own structure and lose the power storage and discharge functions. Low average will affect the performance of the battery

[0003] In some special environments, such as seawater, the battery is susceptible to seawater corrosion, low temperature affects the performance of the battery, and in the desert, the battery is easily damaged by high temperature

[0004] Various protective measures have been designed for batteries in the prior art, the most common is to stick a layer of protective film on the outer surface of the battery, which has simple waterproof and anti-corrosion effects, but the sealing and protection effect is not ideal, and it is not effective in water protective effect

Others place the battery in a protective liquid, such as an oil-immersed internal and external pressure balance battery pack. This kind of battery protection device has a complex structure, high manufacturing process requirements and high cost, which is not conducive to popularization.

[0005] There are also hard or soft packaging boxes to pack the battery. The packaging box is a metal or non-metal shell. The structure of this battery protection device is also complicated, and the sealing protection effect and temperature adjustment function are not ideal.
