China’s first factory dedicated to the mass production of liquid-solid state batteries by Hylic has begun operations in Jiangsu province in the fourth quarter of 2025, marking a milestone in the commercialization of next-generation battery technology.
Hylic, formally known as Heyuan Lithium Innovation, was founded in January 2023 and is headquartered in Suzhou. The company focuses on the research, development, production and sales of solid-state lithium-ion batteries for applications including energy storage systems, power batteries and household appliances.

In December 2023, Hylic signed a project agreement with the local government to establish a liquid-solid state battery mass production base. The project involves a total investment of 5 billion yuan ($716.6 million) and covers 65.3 acres. The facility is designed to deliver 10 gigawatt-hours (GWh) of annual production capacity once fully built.
Construction of the factory is being carried out in three phases. The first phase, occupying 20.84 acres, required an investment of 500 million yuan and includes a 1 GWh production line. The second phase, built on the same site, adds a 2 GWh production line with an investment of 1 billion yuan. The third phase reserves 44.9 acres for a 7 GWh production line, backed by an investment of 3.5 billion yuan.

At the launch ceremony, Hylic also introduced its “Six-in-One Battery” concept, which the company said focuses on improving energy density, safety, capacity, discharge performance, cycle life and cost. The product portfolio targets a range of use cases, from light mobility to automotive and emerging aviation applications.
Hylic said its intelligent lightweight power batteries for small mobility vehicles, such as electric scooters and bicycles, offer energy densities of 250 to 300 watt-hours per kilogram and have passed 1,500 charge-discharge cycles as well as nail penetration safety tests. For low-altitude aviation applications such as electric vertical takeoff and landing aircraft, the company unveiled a battery supporting instantaneous discharge rates of up to 15C and operating temperatures from minus 20 to 55 degrees Celsius.

The company also presented solid-state battery products for embodied intelligence applications, with energy densities ranging from 280 to 360 Wh/kg. Its automotive-grade battery is rated at up to 360 Wh/kg with a cycle life of around 1,000 cycles, according to the company.
The start of operations at the Jiangsu facility underscores growing investment in solid-state and hybrid battery technologies in China, as manufacturers seek higher energy density and improved safety to support electric vehicles, energy storage systems and new mobility segments.
