Co-founded by the technological mastermind behind the 150 kWh WeLion battery pack found in Nio electric vehicles, the institute debuted the tech alongside state-backed asset vehicle China Green Development Group (CGDG). The product unveiling occurred at the 2026 Tianmu Lake New Electrochemical Energy Storage Technology Seminar. The engineering utilises in-situ solidification to chemically transform liquid electrolyte into a stable solid matrix inside the cell casing, aiming to bridge the gap between traditional liquid lithium-ion cells and pure solid-state platforms. Hardware capacity specs The manufacturer introduced two distinct large-format battery cells utilising a lithium-iron phosphate and carbon chemistry. These include a standard utility-grade 314Ah format and a large 588Ah format, optimised for long-duration energy systems requiring extended discharge windows. Both configurations directly scale up the energy density footprints commonly tracked by domestic electric vehicle enthusiasts. Regulatory line adaptations The technology deployment leverages manufacturing parameters that carry deep strategic implications across the wider automotive supply chain. Upcoming national standards taking effect on July 1 strictly define cells with 5% to 20% liquid content as liquid-solid state architectures. This allows conventional liquid factories to adapt lines with under 10% equipment modifications. The structural adaptation effectively bypasses the equipment expectations outlined in our recent report on the illusion of the solid-state equipment market. Rather than being caught in an estimated 62.36 billion yuan (9.15 billion USD) machinery expenditure trap, the venture utilises its active pilot line to manufacture these cells immediately. Competitive industry bottlenecks The rollout targets a commercial window, while major tier-one automotive suppliers face persistent development bottlenecks. Internal evaluation indicates that market leader CATL keeps its pure solid-state battery development fixed at a mid-level maturity rating. This delay allows nimbler joint ventures to deploy high-capacity configurations directly into commercial networks. TIES also finalised a strategic agreement with the Yellow River Delta Jinbo Chemical Research Institute to secure its supply chain for raw energy materials. The institute simultaneously launched a specialised evaluation solution to streamline quality control across materials and membranes. These integrated ecosystems directly support downstream output tracking as localised pilot lines scale up cell production. Source: China Liyang Official WeChat Channels Live Stream
