With the acceleration of social development, people's demand for and dependence on batteries is increasing Batteries are closely related to people's lives.

Main parameter index Lithium-ion batteries have the advantages of high energy density, high conversion efficiency, long cycle life, no memory effect, no charge and discharge delay, low self-discharge rate, wide operating temperature range and environmental friendliness, thus becoming an ideal carrier for electric energy It is widely used in various fields.

There is no characteristic of charging and discharging of lead storage batteries, mainly the chargers used for charging have corresponding indications, such as the 13, 5V cut-off voltage indicator after the full charge, the indicator light after the discharge is completed, the under-current alarm And so on The generator is normal.

Types and performance of electric tricycle batteries: 1) Lead-acid batteries (including lead-acid gel batteries), which are cheap and stable in performance, and are used in electric vehicles on the market.

The formation process of the SEI film in the formation process of the lithium ion battery specifically includes the following four steps:Step 1: electrons are transferred from the inside of the current collector-conductive agent-graphite particles to point A where the SEI film is to be formed;Step 2: The solvated lithium ion is diffused from the positive electrode to the point B of the surface layer of the SEI film being formed under the encapsulation of the solvent;Step 3: The electrons at point A diffuse to point B through electron tunneling;Step 4: The electrons transitioning to point B react with lithium salt, solvated lithium ion, film former, etc, and the SEI film is continuously formed on the surface of the original SEI film, so that the thickness of the SEI film of the graphite particle surface is continuously increased, and finally a complete SEI is formed membrane.

Where does Yinlong lithium-titanate battery technology come from?According to the official website of Yi nlong New Energy Co, Ltd.

With the new policy of “double points”, the new energy vehicle market is driven by policy to become market-driven Strong market demand and continuous research and development technology are gradually reducing the cost of power batteries, and the prices of new energy vehicles are gradually approaching traditional fuel vehicles.

After the battery for the car is used for more than 2 years, the discharge capacity will decrease, and the life of the general vehicle battery will not exceed 4 years Compared with lead-acid batteries, lithium batteries have the advantages of high energy density, long life and small size.

Zhang Xiangmu, director of the Equipment Industry Department of the Ministry of Industry and Information Technology, said at the 2016 China Electric Vehicle Hundred People Forum that the suspension of the ternary lithium battery bus was included in the “Recommended Model Catalogue for New Energy Vehicle Promotion and Application”, which expressed the country’s concern about the safety of the power battery In fact, on January 14 this year, the new car catalogue of the Ministry of Industry and Information Technology has no passenger car products equipped with ternary material batteries.
