On January 20, 2018, the 2018 Forum of China Electric Vehicles 100 People's Association, the head of the overall expert group of the National 863 Program Energy Conservation and New Energy Vehicles Major Project Ouyang Minggao introduced the research progress of power battery Among them, CATL, Lishen, Guoxuan High-Tech, which are responsible for the new lithium-ion power battery project, have chosen the ternary soft-package technology route, and the energy density has reached 300Wh/kg.

Nickel-metal hydride batteries are alkaline batteries Due to the relatively low voltage of the cells and the "memory effect", regular large-scale discharge is necessary, which greatly aggravates the task of the power management system.

According to reports, the Ningde era has mass-produced the ternary 622 power lithium battery, and the fundraising will be used for the Huxi lithium-ion power battery production base project and the power and energy storage battery research and development project In terms of ternary cathode materials, NCM523 is still the main domestic market, but with the advancement of technology and the driving force of the national subsidy policy, the leaders of Guoxuan Gaoke and Dangsheng Technology have been vigorously deploying NCM622 and 811 products.

With continuous movement of pollution prevention and control actions in various places, environmental problems of temporary storage of waste lead-acid batteries have become increasingly prominent, it have been highly valued by relevant government departments, and gradually put on national key control schedule The Ministry of Ecology and Environment, National Development and Reform Commission, Ministry of Industry and Information Technology, and Ministry of Housing and Urban-Rural Development have successively promulgated the "Solid Waste Pollution Prevention and Control Law", "Promoter Responsibility Extension System Implementation Plan", "Domestic Waste Classification System Implementation Plan", and "Discharge Lead Storage Battery Collection and Transfer Management".

The soft-packed battery core is a battery core that uses an aluminum-plastic packaging film as a packaging material Relatively speaking, the packaging of lithium-ion batteries divide into two categories, one is a soft-packed battery core, and the other is a metal-clad battery core.

An article to help you understand the 48v40a lithium battery assemblyQianjiang City 48v40a lithium battery assembly 18650, these figures in the 18650 representing appearance of size: 18 refers to the battery diameter of 18.

Lithium battery charge and discharge control chip UCC3957 can provide protection on overcharge, over discharge and over current for 3 or 4 lithium battery packs Specifically, chip samples each battery voltage in battery pack and internally precision reference voltage compared.

With rapid spread of new energy vehicles, major auto manufacturers have also seen the development of prospects on electric vehicles Many manufacturers have begun to try to introduce electric vehicles.

1 Lithium battery requirements on diaphragmThe performance of diaphragm determines internal resistance and interface structure of battery, which in turn determines battery capacity, safety performance, charge and discharge density and cycle performance.

The ternary lithium battery lifeLithium battery life refers to the battery in use after a period of time, capacity attenuation for the nominal capacity (room temperature 25 ℃, standard atmospheric pressure, and in the battery capacity of 02 C discharge) of 70%, can think life is terminated.
