The semi-solid energy storage lithium battery developed by Chengdu is set to make a significant impact. On March 30, 2025, Chengdu will host the 29th International Energy Conference, where advancements in energy technology are expected to be showcased. This innovative battery technology utilizes a “solid-liquid separation” method, which allows for the efficient separation of lithium ions from the electrolyte and battery system. This approach aims to enhance production, transportation, application, and recycling capabilities.
The battery’s outer casing is designed to have integrated channels that connect with the external energy management system, enabling real-time monitoring. This feature addresses the challenge of large-scale energy storage, particularly in terms of safety and efficiency. According to reports from IT Home, the battery technology was first developed in 2010 at the Beijing Engineering Laboratory and has seen 13 years of technological advancements, culminating in its recent production in Chengdu.
The project adopts a “1+N+M” model for deployment, which includes one central production base in Chengdu, supported by N manufacturing units for lithium-ion components, and M regional service centers both domestically and internationally. The strategic goal is to establish a robust application foundation for energy storage systems.
As a testament to its capabilities, the Chengdu facility has achieved a production line with a capacity of 100MWh, and by July 2024, the first batch of battery products is expected to undergo trial production. These products will also be subjected to external testing, including both short-circuiting and other safety assessments. The upcoming energy storage station is set to enhance applications in various industries.
Simultaneously, the company is collaborating with international partners to establish battery production lines abroad, aiming to become a leading player in the energy storage market. This initiative highlights the company’s commitment to advancing lithium battery technology in China and beyond.
Chengdu’s advancements in energy technology signify a pivotal step towards more sustainable energy solutions, demonstrating the potential for innovation in the battery sector.
