Is the car battery a lithium battery?

Cars are lead-acid batteries. Lithium battery for vehicle is the power battery of hybrid electric vehicle and electric vehicle. Because some technical properties of Ni-MH battery are close to the theoretical limit, lithium battery has the advantages of high energy density, large capacity and no memory.

The disadvantage of automobile lithium battery is that it can't withstand low temperature and high temperature. The lowest temperature can basically reach MINUS 20 degrees, and the highest temperature can be controlled at 60 degrees. The engine room temperature is too high to dissipate heat immediately. Therefore, if the lithium battery can't withstand this high temperature, it will be very sad if it explodes, so this is one of the reasons why the lithium battery is not used in cars.

Battery is an indispensable part of automobile, which can be divided into traditional lead-acid battery and maintenance-free battery.

Because the battery adopts lead-calcium alloy grid frame, the amount of water decomposition and water evaporation during charging is very small, and the sealing structure of the shell also makes the release of sulfuric acid gas very small. Therefore, compared with the traditional battery, it has the advantages of no need to add any liquid and long storage time in the terminal. Million car purchase subsidy
