Description

technical field [0001] The invention belongs to the technical field of accumulators, and specifically discloses a sealed anti-seismic accumulator. Background technique [0002] A battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to be recharged through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery and belongs to the secondary battery. Battery. The battery is the energy carrier of electric vehicles and a key component that affects the performance of electric vehicles. [0003] The battery is mainly composed of battery shell, battery cover, positive and negative plates, electrolyte, separators and accessories, among which the plate is the main part of the battery to store electric energy, and the main assembly method is to overlap several positive and negative plates at intervals , assembled and fixed in the battery case. It is inevitable that the ca...

AI Technical Summary

Problems solved by technology

It is inevitable that the car will bump and vibrate when driving. In the process of long-term use, the battery shell, battery cover and internal structure are prone to loosening, which greatly affects the sealing performance of the battery. At the same time, the battery plate has poor vibration resistance. , the active material on the plate will continue to fall off, resulting in a continuous decrease in the effective reaction area of ​​the plate; when the shed active material accumulates to a certain height at the bottom of the battery, it will cause a short circuit on the plate, causing severe self-discharge, and causing the battery to be scrapped. Reduced service life
