Shulou(Shulou.com)12/24 Report--

CTOnews.com December 1 news, Changan Automobile said in a survey: the development of a leading solid state battery, starting from 2025 gradually mass production application, weight energy density of 350-500Wh/kg, volume energy density of 750-1000Wh / L dint 2030 full-scale application.

In addition, Changan Automobile is carrying out the prototype cell design of lithium-sulfur batteries, metal batteries and other new batteries, and it is expected that the energy density will exceed 1300-1500Wh/kg, and strive to carry applications in 2035.

On the technical route, Changan Automobile focuses on the breakthrough of electric core technology. Carry out technical research on liquid battery material modification and system optimization, constantly improve battery energy density, charge rate to achieve the application of 3C, popularize 5C, pre-research 7C, charge for 7 minutes as soon as possible, with a range of 400 km.

Deep ploughing semi-solid, solid-state battery new electrolyte material development, key process development, based on vehicle demand, forward development of leading solid-state battery, from 2025 to gradually mass production application, weight energy density of 350-500Wh/kg, volume energy density of 750-1000Wh / L, universal application in 2030.

In terms of new batteries, the prototype cell design of lithium-sulfur batteries, metal batteries and other new batteries is being carried out, and the energy density is expected to exceed 1300-1500Wh/kg, and strive to achieve carrying applications in 2035.

In addition to structural innovation and material system innovation, the company will also carry out system integration innovation. Focus on solving the problems of energy replenishment efficiency, essential safety, full-temperature panoramic application, artificial intelligence and the application of large models, and continue to bring leading technical solutions.

In terms of product layout, in terms of batteries, it is planned to launch 8 self-developed batteries, such as liquid, semi-solid and solid, by 2030, forming a battery capacity of 50-80GWh.

In terms of battery Pack integration, the first CTV technology will begin mass production in 2024, achieving group efficiency ≥ 86%.

In the aspect of battery energy system, through the expansion of technology, products and business model, we take "energy" as the main line to create a complete renewable energy ecological circle, form an industrial closed loop of energy production, storage and utilization, and maximize the value of the whole industry chain.

In terms of system capability, Changan Automobile has set up an Advanced Battery Research Institute, with more than 1200 battery research and development personnel, including senior experts and top academic talents. In the future, another 10 billion yuan will be invested and the battery team will reach 3000 people by 2024.

Changan Automobile has built a mature and complete R & D management, capacity management, supply and marketing management system, continuously tackling the core technology, and will focus on material innovation, system integration innovation and other aspects to achieve new breakthroughs.

At the Guangzhou Auto Show, Changan Automobile released its own battery brand and named it Changan "Golden Bell cover". As implied by the brand name, Changan Automobile's battery system will be repaired internally and externally with solid internal work to comprehensively solve users' anxiety in terms of energy density, charge and discharge efficiency, cycle life, low temperature performance, and so on. bring users a new experience of "long life", "really safe", "super-efficient" and "fast energy replenishment".

CTOnews.com previously reported that Changan Automobile, Deep Blue Automobile and time Changan Power Battery Co., Ltd., a battery company co-founded by Ningde Times, officially went offline on November 24.

According to reports, its first standard cell adopts advanced "fast ion ring graphite" and "ultra-high conductivity electrolyte" material technology, more than 6800 quality control points are embedded in the whole life cycle, more than 10,000 items of data can be traced back to the source, and the quality reliability can reach the level of DPPB (monomer defect rate 1/1000000000).

The automatization rate of Changan factory is more than 95%, and a battery can be produced in 1 second in the whole cycle from feeding to finished product production. Changan Automobile previously said on the interactive platform that time Changan, which is mainly engaged in the production of power cells, will have an annual production capacity of 25 Gwh and will be put into production within this year.
