Not long ago, the “Energy Storage International Summit and Exhibition 2018” held in Beijing gathered leaders of industry leaders, experts and scholars, and representatives of many well-known enterprises at home and abroad With the increasing maturity of the energy storage industry's application scale, safety and economy, the energy storage industry is rising as a new star in the new energy application industry.

According to the latest data from the High-tech Industrial Research Institute (GGII), in April 2018, domestic new energy vehicles produced about 87,000 vehicles, a year-on-year increase of 148%; the total installed power of power batteries was about 376GWh, a year-on-year increase of 304%.

Electric cars consume electricity in use, so how to charge it? There must be some charging equipment Today, I will tell you what are the charging piles and charging stations, and the differences between them.

It is impossible to verify when the concept of pure electric vehicle was put forward, but in recent years, whether Chinese or global cars, new energy vehicles based on pure electric vehicles have become the development direction of major manufacturers, and at the same time, various countries have given a lot of support policiesBut, with the development of China's new energy vehicles, the development of pure electric vehicles is not ideal, especially compared to plug-in electric hybrid, both in sales and market share is not high.

The strategic cooperation of vehicle enterprises and power battery enterprise is further deepenedOn July 4, dongfeng times (wuhan) battery system co.

Due to the low diffusion coefficient and poor conductivity of lithium ions, the current practice of lithium iron phosphate batteries is to make their particles small, or even make them into nano series, and improve their charging and discharging speed by shortening the migration path of LI+ and electrons (theoretically, the migration time is inversely proportional to the square of the migration path) But this brings a series of difficulties to the lithium battery processing.

Introduction to lithium iron phosphate batteryLithium iron phosphate battery refers to the lithium ion battery with lithium iron phosphate as the positive electrode material The cathode materials of lithium ion battery mainly include lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials, lithium iron phosphate, etc.

The overnight nickel plate opened at $15,005/ton At the beginning of the day, nickel was fluctuating around the daily average.

Wuhengan, a professor at the University of Science and Technology of China, has worked with Nobel Prize winner Andelie·haimu, a professor at the University of Manchester in the United Kingdom, to discover that graphene oxide films have the properties of precision and rapid ion screening The results were recently published in the journal Science.

In recent years, it has been said that once a lithium-ion battery is used, it will be charged according to standard time and procedures, and it will begin to calculate its life span If the life span is generally about two years, whether you use it or not, it may be shorter if you do not save it properly.
