Waterproof early warning battery

Abstract

The invention discloses a waterproof early warning battery which comprises a battery shell. The battery shell consists of a packaging layer, a middle layer and a seal layer. A first opening is formed in the front end face of the packaging layer. A second opening is formed in the front end face of the middle layer. The right side of the seal layer is connected with a connecting line, and a battery pack is arranged in the seal layer. The right side of the connecting line is connected with a connector. The battery pack consists of a battery core shell, a battery bracket and a cover plate. The battery core shell consists of an outer shell and an inner shell. An insulating material is arranged in a cavity. A parallel battery core group is arranged in the battery bracket. A groove is formed in the cover plate. A reinforcing steel plate is arranged at the bottom of the groove. An early warning circuit and an alarm apparatus are welded at the top of the reinforcing steel plate. The waterproof early warning battery is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a lithium battery, in particular to a waterproof early warning lithium battery. Background technique [0002] Batteries are widely used as an energy source. The positive and negative electrodes of the battery are usually metal terminals with good conductivity. If it is used in water or a humid environment, due to the conductivity of water, the battery will short-circuit itself, which will not only consume energy in vain. , will also cause safety problems, so when the battery needs to be used in a water environment or a humid environment, the battery must be waterproofed. The usual sealing body will cause difficulty in heat dissipation when the battery is working, and even cause safety problems; compared with Traditional lead-acid batteries, lithium batteries have obvious advantages. Its energy ratio is higher, its service life is longer, its rated voltage is higher, its self-discharge rate is lower, and its weight is lighter, m...

[0002] Batteries are widely used as an energy source. The positive and negative electrodes of the battery are usually metal terminals with good conductivity. If it is used in water or a humid environment, due to the conductivity of water, the battery will short-circuit itself, which will not only consume energy in vain. , will also cause safety problems, so when the battery needs to be used in a water environment or a humid environment, the battery must be waterproofed. The usual sealing body will cause difficulty in heat dissipation when the battery is working, and even cause safety problems; compared with Traditional lead-acid batteries, lithium batteries have obvious advantages. Its energy ratio is higher, its service life is longer, its rated voltage is higher, its self-discharge rate is lower, and its weight is lighter, more energy-saving and environmentally friendly. Many advantages make lithium batteries It is widely used in every corner of life, but the current lithium battery still has potential safety hazards. In the past few years when lithium batteries have been used, it is often reported that lithium batteries explode during charging. The reasons for the explosion of lithium batteries are roughly divided into Three types: external short circuit, internal short circuit, and battery overcharge. The direct cause of the explosion is that the internal temperature rises due to the short circuit of the battery, and the electrolyte in the battery is heated and vaporized, causing the battery to expand and cause an explosion. burning, causing serious safety accidents
