"Blade battery" leads the new route of technology -Lithium - Ion Battery Equipment

Only fight for the day and night, reveal the list and take the lead. Changsha's 22 emerging and advantageous industrial chains dance strongly, becoming the main battlefield for the implementation of the "three highs and four new" strategy. Red Net Changsha Station plans the "Commanding Heights - Changsha Industrial Chain Contributions "Three Highs and Four New" Series Reports", focusing on the leading industries in the country and the world's first-class among the 22 industrial chains, showing that Changsha gallops on the main battlefield of high-quality development and undertakes the "three highs and four new" series. The rising trend of the "high four new" main force and the main position of the top provincial capital city.

The battery is the heart of an electric vehicle, and its "blood supply" is related to the longevity of the car's service life.

In Changsha, BYD "Han" owners have deep feelings about the high efficiency of charging: in just half an hour, the power of the car can be increased from 10% to 80%, and the cruising range after being fully charged can reach 605 kilometers. This stems from the excellent performance of the "battery pack" in the body.

The "battery pack" consists of a number of blade-shaped batteries with a length of 96 cm, a width of 9 cm and a height of 1.35 cm, arranged in an array. As soon as the world's first "blade battery" was put on the market, the global new energy vehicle market was impressed. The Fudi Battery Changsha Base located in the High-tech Zone of Ningxiang City has sufficient orders and busy production. This is the second "blade battery" factory that Fudi Battery has put into production nationwide.(Lithium - Ion Battery Equipment)

The world's first, opening up a new technology route for automotive power lithium batteries

In the field of electric vehicles, there has always been a battle between lithium iron phosphate batteries and ternary lithium batteries. For a long time, in order to pursue higher energy density and increase cruising range, almost all domestic and foreign car companies choose ternary lithium batteries. But at the same time, the spontaneous combustion of electric vehicles is frequent.

"At a high temperature of 500 ℃, the structure of lithium iron phosphate material is very stable, but the ternary lithium material will decompose at about 200 ℃, and the chemical reaction is more violent, which will release oxygen molecules, which is more likely to cause thermal runaway." Changsha Fu The technical staff of Di Battery Company said that the "blade battery" made of lithium iron phosphate material has a structure similar to the honeycomb aluminum plate, which not only greatly improves the safety performance of the battery pack, but also improves the space utilization rate inside the battery pack compared with that of the traditional battery pack. 50%.

Since the single battery is inserted into the battery pack like a blade, redundant modules are reduced. The blade battery achieves higher volume utilization and greatly improves the energy density. The battery can be charged and discharged more than 3000 times, and the vehicle cruising range Up to 605 kilometers, to achieve the same level as the ternary lithium battery.

What is worth looking forward to is that the "blade battery" is expected to reshape the new technology route of the global power lithium battery.

The faucet dances again, stirring up a pool of living water

On December 15, 2020, Fudi Battery Changsha Base in Ningxiang High-tech Zone was successfully mass-produced, using the world's first sixth-generation power lithium battery production line, consisting of robots, MES information systems, intelligent logistics systems and many more. It is composed of functional unmanned trucks, etc., to realize the automation and informatization of the production line, and to realize the intelligent interconnection of the hardware and software of the fully automatic production line.

The planned land area of ​​the Changsha base is 614 mu. At present, the project has been fully completed and mass production has been realized, with a total output of 10GWh and an annual output of 4GWh in the first year. After full production, the annual output value will reach about 10 billion yuan, which can drive an additional annual output value of 6 billion yuan in the upstream supporting facilities of the energy storage material industry chain.
