Lithium battery multi-technology route dark battle -Lithium - Ion Battery Equipment

Rising raw material prices, the conflict between Russia and Ukraine, the opening of the "Double Carbon" campaign, repeated outbreaks of COVID-19, and blocked supply chains... In 2022, the auto industry seems to be facing a more difficult test. Even so, the promotion of new energy vehicles is still spreading around the world, bringing a glimmer of hope to the struggling auto market. Driven by strong demand in my country and Europe, global electric vehicle sales will double to 4.6 million in 2021, surpassing hybrids for the first time, the latest figures show. In the upstream of the supply chain, the power lithium battery industry is moving forward under pressure, not only the output is rapidly increasing, but also new technologies are introduced.

For a long time, reducing costs and seizing market share through technological innovation is the foundation of the company's foothold. The reporter learned that in the new stage of the marketization of the new energy vehicle industry, the competition among power lithium battery companies is, to a certain extent, the battle of different technical routes. Among them are mass-produced products with relatively bright market prospects, innovative technologies that are about to be put into mass production and whose application effects are yet to be tested, and cutting-edge achievements with brighter prospects and very attractive futures. It is very important to grasp the present, and it is also important to lay out the future. The "dark battle" of the multi-technical route of the power lithium battery industry is constantly escalating.(Lithium - Ion Battery Equipment)


CTP3.0 "Kirin Battery" iteratively came out

As a leader in the power lithium battery industry, CATL has been promoting the development of vehicle electrification with technological innovation. On the official website, it focuses on CTP, CTC, high nickel and high voltage technologies.

Compared with the traditional battery packs currently on the market, CATL pioneered the CTP (CelltoPack) high-efficiency grouping technology in the industry. By simplifying the module structure, this technology increases the volume utilization rate of the battery pack by 20% to 30%, reduces the number of parts by 40%, and increases the production efficiency by 50%. After being put into application, the manufacturing cost of power lithium batteries can be greatly reduced. It is reported that the average energy density of traditional battery packs is 140-150Wh/kg, while that of CTP battery packs reaches more than 200Wh/kg. CATL debuted the CTP battery pack at the 2019 Frankfurt Motor Show, and then cooperated with BAIC New Energy to realize the first mass-produced model application.

After several years of rapid development, CATL's CTP technology has been continuously updated. In March this year, Wu Kai, CATL's chief scientist, said that the company has developed a third-generation CTP technology through technical iterations, which can be applied to its lithium iron phosphate batteries and ternary lithium batteries, also known as "Kirin batteries". It is reported that the CTP3.0 technology is ready for mass production and is expected to be officially launched in April this year. According to the data, CTP3.0 consists of a platform cell module, an expandable electrical module, a flexible and extensible thermal management module, and a flexible and extensible box module. The cell module is still in the form of a square battery, which can make better use of the entire battery. Group of space.

Wu Kai said that the system weight, energy density and volumetric energy density of Kirin batteries will continue to lead the industry's highest level. "2023 will be a key time node for electric vehicles to exceed 1,000km of driving range and enter mass production. The importance of the latest CTP technology will be greatly enhanced in the future." According to him, lithium iron phosphate batteries using CTP3.0 technology The energy density can reach 160Wh/kg, and the ternary lithium battery can reach 250Wh/kg. It is worth mentioning that, under the same conditions, the products using CTP3.0 technology can have 13% higher power than the 4680 battery system.

In addition, CATL also proposed the CTC (Cell to Chassis) technology, which integrates the battery cell with the body, chassis, electric drive, thermal management and various high and low voltage control modules, so that the vehicle mileage can exceed 1000km; and through the intelligent power domain The controller optimizes power distribution and reduces energy consumption, reducing power consumption per 100 kilometers to less than 12kWh. It is reported that CATL will officially launch a highly integrated CTC battery around 2025.
