Weijing Energy Storage

The company's primary offering is a zinc-iron flow battery, a technology with roots dating back to the 1970s. This battery chemistry utilizes an alkaline aqueous electrolyte, rendering it non-flammable and non-explosive. Key attributes of this technology include its inherent safety, suitability for long-duration storage, and a long operational lifespan. A significant commercial advantage stems from the use of abundant and low-cost raw materials like zinc and iron. The system architecture is modular, allowing the power (kilowatt) and capacity (kilowatt-hour) components to be scaled independently, which provides flexibility in system design and storage duration to meet specific client needs.

Weijing Energy Storage serves clients in the energy sector, providing solutions for grid-scale applications, renewable energy integration, and microgrids. Its business model encompasses the manufacturing and sale of these battery systems, alongside the development of energy storage power stations. The company has engaged in several key projects, including a 100kW/400kWh system for a Zero-Carbon Smart Integrated Energy Center in Shanghai and a 200kW/600kWh pilot project in Jiangxi, demonstrating functions like peak shaving, grid stabilization, and power fluctuation smoothing for solar power stations. To support its production, Weijing is developing gigawatt-scale intelligent manufacturing facilities, referred to as "Giga+ Factories," with one having commenced production in Guangdong in late 2023 and another under construction in Inner Mongolia.

The company has secured significant financial backing from a range of investors. In March 2023, it announced the completion of a CNY 600 million Series A funding round led by state-affiliated investors. Other notable investors include Gaorong Capital, ZhenFund, Green Pine Capital, and China SDIC Gaoxin. On July 18, 2024, the Chairman of WeView Energy, Ge Qun, delivered a keynote speech on the importance of long-duration energy storage.
