China's First Mass-Production Solid-State Battery Plant Launches; Heyuan Lithium Unveils "Liuhe Battery"

On January 10, Heyuan Lithium Innovation held a ceremony in Huai’an, Jiangsu Province to mark the official launch of its solid-state battery manufacturing facility and the delivery of its new products. This facility is China’s first factory dedicated exclusively to the mass production of solid-state batteries, integrating R&D, manufacturing, and testing capabilities. It officially commenced operations in Q4 2025, achieving full-scale production and product delivery just three years after the company’s founding. At the event, the company unveiled its “Liuhe Battery,” designed for multiple application scenarios and optimized across six key dimensions: energy density, safety, capacity, charge/discharge rate, cycle life, and cost. The product portfolio includes solutions for smart light electric vehicles (250–300 Wh/kg, 1,500 cycles), low-altitude aircraft (15C discharge rate, operating temperature range of -20°C to 55°C), embodied intelligent devices (280–360 Wh/kg), and automotive-grade applications (360 Wh/kg, 1,000 cycles). During the ceremony, Heyuan Lithium Innovation delivered its first batch of products to its strategic customer, Jiushi Intelligence.
