[WELION New Energy: Large-Scale Adoption of Solid-State Batteries Will Occur in the ESS Sector] On February 27, during the 2025 International New Energy Industry Marketing Summit, Wei Jizhou, Deputy General Manager of Beijing WELION New Energy, delivered a keynote speech titled "Current Commercialization Progress of Solid-State Lithium Batteries." He stated that the large-scale adoption of solid-state batteries will occur in the ESS sector. In the composite route of solid-state batteries, the biggest challenge lies in interface issues, and the in-situ solidification approach helps address this problem, facilitating the standardized mass production of hybrid solid-liquid batteries. WELION New Energy has established a fully solid-state battery company in Shenzhen and set up a factory in Zhuhai. Currently, the communication base stations in Dongguan primarily use the company's half-solid state batteries, and it is expected that the deployment of 1,000 base stations will be achieved before September.
