What about lithium manganate batteries? How about the application in the field of global new energy vehicles?

Recently, at the invitation of the host Fang Jie can science and technology, Shanghai star "new energy automobile big classroom" ushered in the constant research and development director, Mr. Cheng Kai for OEMS, PACK enterprises, batteries, solution providers such as industry elite to do "super manganese acid lithium technology and application of" the theme of the speech, see below:

Japan and South Korea enterprise will manganese acid lithium battery widely used in international new energy vehicles main brands

AESC, Toshiba, Hitachi, Japan and South Korea, such as LG battery LEJ will manganese acid lithium batteries are widely used in Japan, Korea, Europe and the United States and other mainstream brand new energy vehicles. Especially the Nissan LEAF by the end of 2016 total sales of 350000 units. Japan's battery manganese acid lithium battery is given priority to with big doped crystal particles: slightly lower g capacity, design surface density is low, high temperature and good cycle performance; With three yuan or binary mixing materials used.

In our country, manganese acid lithium battery is mainly used in the field of new energy of commercial vehicles

, due to the different route of China's new energy vehicle promotion to the most outstanding commercial lithium iron phosphate, and contrast with the pursuit of power, began to accelerate the three yuan. However, represented by star constant power lithium battery companies are still used in line with international standards of manganese acid lithium technology solutions, and carried out a bold innovation, exert its advantages, the main applications in the field of commercial vehicles.

Different materials have different advantages and disadvantages, star constant manganese acid lithium foster strengths and circumvent weaknesses

Ordinary lithium manganese acid has the advantage of high voltage platform and low temperature property is good, good times permeance and comprehensive cost-effective; But the disadvantage is that the energy density is low, poor heat circulation and storage.

How do you foster strengths and circumvent weaknesses become with manganese acid lithium materials factory need to solve the primary problem. Cheng Kai is introduced: "unlike Japanese companies, star constant of manganese acid lithium used by a reunited particles and secondary particles, by doping and cladding both solution by modifying material: improve the grams of manganese acid lithium capacity; Improves the high temperature cycle performance and storage performance of the battery; On sheet design is adopted high surface density design."

Star constant super manganese acid lithium - cost-effective power lithium batteries

After years of research and development and improve the constant launched with a high cost performance "super manganese acid lithium", has long cycle life, low cost and the second life of three characteristics.

Since 2006, global trail 4 million light electric vehicle adopts star super manganese acid lithium battery, it's been 14 years, five inspection of the life cycle of market application. By the end of 2016, star of constant power nearly 20000 electric cars for the domestic lithium battery, especially in the field of electric vehicle logistics in a leading position.

Subsidies TuiPo and marketization, manganese acid lithium prospects

"Under the battery" high energy density "guide, lithium manganese acid development once frustrated. However, power battery not one-sided pursuit of a single performance.

If you don't make a change, the domestic enterprise into manganese acid lithium materials technology development will be affected, ready to use as manganese acid lithium power battery factory also dwindling, can lead to the development of the whole system behind Japan and South Korea enterprise will form a "circle". Cheng Kai said in his speech, "as state subsidies TuiPo, new energy automobile market pressure, but the star constant of lithium manganese acid system is full of confidence, promoting the comprehensive ratio of power battery, let new energy cars are widely popular, is the future."

He said: "the manganese acid lithium material itself has the outstanding cost advantage. With the development of domestic new energy vehicles, lithium ion batteries raw material rises in price considerably: six fluoride phosphate lithium carbonate, lithium, nickel, cobalt, copper and none survived, main material and only manganese acid lithium manganese dioxide of price stability.

Star constant hope that through continuous efforts, in 2020, when the battery cost down to $1 per watt. Only comprehensive performance is superior to the traditional fuel vehicles, new energy vehicles to achieve the real market-oriented. Manganese acid lithium battery, especially star constant "super manganese acid lithium promising!" "
