Dr Ruitao Shi

Chief Technology Officer

New Energy Technology Co., Ltd. Thailand

Dr. honglin Liu is a distinguished expert in all-solid-state battery (ASSB) technology, with over a decade of deep expertise in sulfide-based ASSB R&D and industrial scaling.

He has spearheaded the end-to-end construction of ASSB R&D and manufacturing systems, covering laboratories, pilot lines and a 200 MWh mass production line. His landmark technical breakthroughs include stable kilogram-scale batch synthesis of sulfide and halide electrolytes, and large-format cells with capacity exceeding 60 Ah. He resolved critical process bottlenecks such as electrostatic film formation, lifting the fabrication yield of large-size ASSB cells from less than 10% to over 90%. He has a proven track record of building technical teams from scratch, and delivers full-cycle project execution from technology roadmap planning to mass production ramp-up.

Case study

Recent breakthroughs in All-Solid-State Batteries (ASSBs) are reshaping the energy storage landscape, driven by next-generation superionic solid electrolytes that offer unparalleled thermal safety and energy density. Advanced sulfide-, halide-, and oxide-based configurations are maximizing ion conductivity, effectively unlocking the potential of high-voltage cathodes and pure lithium-metal anodes. However, scaling these innovations places unprecedented pressure on critical raw material supply chains. Beyond the surging global demand for battery-grade lithium, the synthesis of advanced solid electrolytes requires large-scale, high-purity inputs of strategic elements such as phosphorus, sulfur, and rare halides, necessitating urgent supply chain diversification and mineral security to achieve commercial viability.
