Analyzing the development of the electric car battery

Source: 2020 - 04 - Bank against 10 hits: times of the development of electric vehicle batteries with the development of the society, energy is becoming more and more scarce, development of new energy is particularly urgent. Constantly in the process of human progress, the progress of the society, the constantly improving standard of living has brought serious challenges to our survival environment, the environmental pollution is an important reason of waste emissions in the process of industrial production, automobile exhaust emissions is one of the culprit causing air pollution, so the development of a new energy environmental protection is the necessity of social development. In this context, the study found that the electric car can be used to replace the traditional fuel cars. Electric cars rely on batteries for electric drive motor rotation. In life, we usually call battery cell, it is a kind of device to store electrical energy, chemical energy and electrical energy conversion by chemical reactions. When charging, electrical energy into chemical energy. In use, chemical energy is converted into electrical energy. Compared with the traditional automobile device, battery light weight, low cost, small pollution to the environment. At present, the market is the main battery lead batteries and fuel cells. Battery energy storage technology is not mature in the past, especially there are many shortcomings in safety performance, service life and cost, in recent years, due to national attention and encourage, battery industry has been rapid development, improving battery performance, can meet the needs of industrial development step by step. The most widely used lead-acid battery price is low, but high density, low power, the average life expectancy is short, usually no more than 2 - For five years. There are a lot of security problems to be solved. Therefore, in the future, we need to study a kind of high power, long life, low cost of new cells to replace it. This innovation will help to promote the electric car industry and the development of other electric machinery industry.
