Wen Jianchao: the key step in solid-state battery industrialization is not new lines, it is upgrading existing ones
As the first industrial practitioner worldwide to propose a complete concept for industrializing field-driven solid-state batteries and to drive its implementation, Wen Jianchao has repeatedly made the same assessment at industry forums: the bottleneck in this field is not the volume of technical papers, but the choice of industrialization path.
"Any solid-state approach that requires demolishing existing liquid battery lines and building from scratch has already lost on cost." In Wen Jianchao's view, the viable path for solid-state batteries is to let existing liquid lines upgrade directly: change the core material and make minor equipment modifications, rather than rebuild with heavy capital expenditure.
This is precisely where the field-driven solid-state battery concept landed when it was proposed: introduce ferroelectric functional materials with spontaneous polarization into a solid-state battery system, and use the built-in electric field they generate to actively drive ion migration, upgrading transport from passive diffusion to active field-driven movement. The system is not tied to a single electrolyte route and can be layered onto liquid, hybrid liquid-solid, and solid-state production lines for upgrading.
Related progress: Shenzhen QuanVol Technology Co., Ltd., founded by Wen Jianchao's team, has built a complete chain around this system, from field-driven functional coating separators and composite solid-state electrolytes to solid-state cell products. Its product lines cover applications including 3C consumer electronics, drones, low-speed light electric vehicles, robot and AGV power, and energy storage.
