Changan Automobile's semi-solid-state battery is expected to debut at the end of 2026, Zhu Huarong revealed the news in advance

According to news on April 19, Changan Automobile Chairman Zhu Huarong revealed at the recent 2023 performance briefing that the company is actively developing semi-solid batteries and is expected to launch them on the market by the end of 2026.

The company’s previously disclosed product layout information shows that they plan to launch 8 self-developed batteries by 2030, including liquid, semi-solid and solid-state batteries, and are expected to form a battery production capacity of 50-80GWh. This series of research and development work not only covers material modification and system optimization of liquid batteries to improve battery energy density and charging speed, but also includes the research and development of semi-solid and solid-state batteries.

According to the editor’s understanding, Changan Automobile has made significant progress in battery technology. They plan to use technical research to increase the charging rate of liquid batteries to 3C applications, popularize 5C, and even the pre-research stage of 7C, which can be fully charged in 7 minutes at the fastest, providing a range of 400 kilometers. At the same time, the company also plans to gradually produce and apply solid-state batteries from 2025. Its weight energy density is expected to reach 350-500Wh/kg, and its volume energy density reaches 750-1000Wh/L. It is expected that by 2030, this kind of battery will be fully popularized.

In terms of new battery research and development, Changan Automobile is also taking precautions and is carrying out the design work of prototype cells such as lithium-ion batteries and metal batteries. It is expected that the energy density of these new batteries will exceed 1300-1500Wh/kg, and strives to Implementation of on-board applications in 2035.

In addition, Changan Automobile also has comprehensive plans in battery pack integration and battery energy systems. They plan to start mass production of the first CTV technology in 2024, achieving a group efficiency greater than or equal to 86%. At the same time, the company also plans to build a complete renewable energy ecosystem with "energy" as the main line, covering the production, storage and utilization of energy, so as to maximize the value of the entire industry chain.

In order to support this ambitious R&D plan, Changan Automobile has established an advanced battery research institute with more than 1,200 R&D personnel, and plans to invest 10 billion yuan in the future , it is expected to expand the battery R&D team to 3,000 people in 2024. Previously, at the 2023 Guangzhou Auto Show, Changan Automobile also released its self-developed battery brand "Jinzhongyu", aiming to solve users' problems in energy density, charge and discharge efficiency, cycle life, low-temperature performance, etc.

The above is the detailed content of Changan Automobile's semi-solid-state battery is expected to debut at the end of 2026, Zhu Huarong revealed the news in advance. For more information, please follow other related articles on the PHP Chinese website!
