From the trial production line of solid-state batteries to the upcoming launch of sodium batteries, there have been frequent breakthroughs in the field of power batteries recently. In various cutting-edge fields, many enterprises are accelerating their efforts to continuously promote technological progress and industrial landing. Industry experts say that as the core component of new energy vehicles, power batteries have entered a stage of diversified exploration of cutting-edge technologies with the support of multiple favorable factors. With the steady promotion and application of related technologies, it is expected to help the new energy vehicle industry achieve further development in safety, efficiency, and other aspects. Not long ago, CATL released the first mass-produced sodium ion battery Tianxing II light commercial low-temperature version in the light commercial field, and announced that it has completed winter standard testing in Jianghuai small trucks and ZhongVAN (vans), and will achieve mass production in July 2026. BYD has also previously released its first sodium battery for use on forklifts. According to Gao Huan, Chief Technology Officer of CATL, sodium ion batteries do not require heating of the battery cells in low-temperature environments, and can still maintain over 92% of available power at minus 20 ℃, effectively improving the vehicle's range and starting reliability in low-temperature environments. In the future, sodium batteries are expected to become an important component of the diversified layout of battery technology. With their low-temperature performance, safety, and potential cost advantages, they can open up incremental space in specific application scenarios and markets, and work together with lithium batteries to meet diversified needs in different scenarios. ”Gao Huan said. In the field of solid-state batteries, many companies have also made positive progress. The person in charge of the solid-state battery project of GAC Group told reporters that GAC has built its first pilot production line for all solid state batteries and is simultaneously conducting trial production and performance optimization of vehicle grade high-capacity all solid state battery cells. It is planned to start small-scale loading experiments in 2026. Solid state batteries combine high energy density and high safety, which can break through the performance bottleneck of traditional liquid batteries, further improve the range and safety of new energy vehicles, and enhance the competitiveness of products. Guangzhou Automobile Group plans to gradually achieve small-scale implementation and popularization from 2027 to 2030. It is expected that this technology will enter a mature development stage in the industry after 2030. ”The person in charge mentioned above said. According to the relevant person in charge of Dongfeng Motor, Dongfeng has successfully developed a new generation of 350Wh/kg high specific energy solid-liquid hybrid batteries, which are expected to be mass-produced on Dongfeng's independent new energy brand vehicles by 2026. At the same time, we are also laying out various technological routes, and preliminary research has been launched on a 500Wh/kg energy density sulfide system solid-state battery. With the support of policies and capital, the timetable for solid-state batteries to enter the market is becoming increasingly clear. It is expected that solid-state batteries will achieve a demonstration of thousands of vehicles by 2027, and achieve large-scale industrialization and vehicle application by 2030. ”In fact, car companies such as BYD and SAIC have made new progress in the application of solid-state batteries, and several leading companies have proposed plans for small-scale mass production and application by 2027. Zhang Yongwei, Chairman of Chebaihui, stated that based on the comprehensive progress of the industry, it is expected that from 2026 to 2027, all solid state batteries will enter the stage of small-scale production and vehicle demonstration. By around 2030, they will have preliminary conditions for large-scale application, and the energy density of battery cells is expected to further increase to 400Wh/kg to 500Wh/kg. In response to the recent trend of intensive breakthroughs in the domestic power battery track, the project leader of GAC Group's solid-state battery project analyzed that its core driving force is the coordinated support of four factors: policy, technology, industry, and capital. The national and local governments have introduced policies such as R&D subsidies and improved standards, leading to continuous breakthroughs in material and process innovation, deep integration of the upstream and downstream of the industrial chain, accelerated localization of equipment, and the scale effect formed by capital tilt and capacity expansion, jointly promoting the landing of technology and the transformation of achievements. The development of power batteries will fundamentally enhance the product strength of new energy vehicles, optimize the cost structure of the entire vehicle, promote the reconstruction of the upstream and downstream of the industrial chain, dispel user concerns, further improve the penetration rate of the new energy vehicle market, and help the industry advance towards high-end and global development. ”The above-mentioned person in charge stated. Hu Song, a senior expert at China Automotive Data Co., Ltd., also believes that the current power battery technology is in a stage of diversified exploration and steady progress, and the industry's focus is shifting from pursuing high energy density to comprehensively improving safety. At present, new routes such as solid-state batteries and sodium batteries are receiving much attention, and industrialization needs to be further promoted. The battery structure technology is also continuously improving, such as various integrated solutions, which significantly enhance the structural strength and safety performance of battery systems. In the coming years, the industry will continue to focus on improving safety performance and optimizing system integration while ensuring supply chain stability and controllable costs, promoting the healthy and sustainable development of the new energy vehicle industry. ”Hu Song said.
