Weekly Hot ： the Initial Implementation of Semi-Solid-State ESS

SMM November 20 News:
Highlights: Industry consensus this week was that the semi-solid-state route will commercialize first, focusing on the low-altitude economy and ESS. The 200MW/800MWh semi-solid-state BESS project in Wuhai entered the final sprint stage, while Hymson and Lead Intelligent Equipment made breakthroughs in solid-state battery equipment and key processes.

This week remained a week of continuous industry conferences, with few major but many minor developments in the solid-state battery sector. The industry consensus is that semi-solid-state (solid-liquid hybrid) batteries will lead the way initially, targeting markets in the low-altitude economy, consumer electronics, and humanoid robots.

The price of lithium sulfide stabilized with a slight rebound this week, primarily due to high demand for cost-effective products in the downstream market, while transactions were still dominated by small orders.
