academician ouyang minggao first pointed out that the development of new energy vehicles is not limited to power electrification, but also needs to focus on energy greening, which is the key to realizing true new energy vehicles. he emphasized that the original intention of china's new energy vehicle industry lies in energy security and environmental protection considerations. therefore, the new energy revolution is the key to promoting the sustainable development of the new energy vehicle industry.

when reviewing the development of china's power batteries, academician ouyang minggao divided it into three ten-year stages: the first decade focused on the safety research of power batteries, the second decade focused on the artificial intelligence revolution and the development of smart batteries, and the third decade will focus on the innovation of material systems and the research and development of solid-state batteries. he pointed out that china's power battery technology breakthroughs are an important factor in promoting the explosive growth of new energy vehicles.

academician ouyang minggao elaborated on the three key directions of current power battery technology: safe batteries, smart batteries and solid-state batteries. in terms of safe batteries, he introduced the research results of improving battery safety through material innovation and thermal management optimization; in terms of smart batteries, he emphasized the importance of intelligent battery simulation and design, intelligent manufacturing and intelligent management; and in terms of solid-state batteries, he planned in detail the research and development path of solid-state electrolytes, composite negative electrodes and composite positive electrodes, and looked forward to the performance of solid-state batteries in different application scenarios.

looking into the future, academician ouyang minggao believes that the technological transformation of lithium-ion power batteries will continue for a long time, and high-energy-density all-solid-state batteries and low-cost, long-life lithium-ion batteries will occupy an equally important position in china's power battery industry. at the same time, he emphasized the importance of energy conservation and emission reduction and green manufacturing, and pointed out that the transfer of the power battery industry to the western region with abundant renewable energy will be an important direction for the development of china's battery industry.
