Sinopec Completes Polymer Solid-State Battery Microgrid Demonstration
- Sinopec completed a polymer solid-state battery microgrid demonstration at the Baiyun comprehensive energy station in Suzhou, Jiangsu.
- Project partners included Sinopec Research Institute, the Sales Company and Jiangsu Petroleum, with initial operational verification at a Jiangxi Petroleum station.
- System uses polymer solid-state (gel) batteries with polymer solid electrolytes and incorporates TOPCon flexible and perovskite photovoltaic modules.
- Following increased energy cabinet capacity and a self-developed intelligent microgrid control system, peak daily charging volume rose 47% and the storage system ran stably.
Project overview
Sinopec completed a polymer solid-state battery microgrid demonstration at the Baiyun comprehensive energy station in Suzhou, Jiangsu, developed jointly by the Sales Company, Sinopec Research Institute and Jiangsu Petroleum, and integrating a self-developed intelligent microgrid system.
Technology
The system uses polymer solid-state (gel) batteries based on polymer solid electrolytes—replacing liquid electrolytes to improve safety, energy density and cycle life—and for the first time integrates TOPCon flexible photovoltaic modules and perovskite photovoltaic modules.
Deployment and testing
A battery energy storage cabinet was designed to meet petrochemical safety requirements; initial operational verification took place at a Jiangxi Petroleum energy station, and the Baiyun site received increased cabinet capacity plus the intelligent microgrid control upgrade.
Operational results
After the upgrade, peak daily charging volume increased by 47% versus prior performance and the energy storage system has been operating steadily, supporting higher utilization of green electricity.
