Utilizing large-scale renewable energies is the key to achieving carbon neutrality. However, the renewable powers like solar and wind is naturally unstable and intermittent. An energy storage system (ESS) is essential to overcome the intermittency of renewables. The scale of battery for ESS will be tremendous for utilization of renewable energy in the near future. Yet, commercial Li-ion battery energy storage faces issues like flammability, limited life cycles and increasing cost, making it not an ideal candidate for large-scale ESS.

The novel flow battery technology innovated by our team employs aqueous electrolytes, which is inherently inflammable. The battery is made from earth-abundant elements as active materials, which is low-cost and eco-friendly. The novel highly selective ion-exchange membrane developed by the team greatly promotes the charge-discharge life cycle of the aqueous flow battery to thousands of cycles. The estimated battery lifetime is over 15 years, which doubles the lifetime of Li-ion batteries. We aim to provide a secure, low-cost, and eco-friendly battery solution to accelerate the progress of carbon neutrality.

可再生能源是實現碳中和的必經之路，要克服風電、光伏等可再生能源不穩定的問題，電力儲存技術是可再生能源的大規模應用的關鍵。在不遠的未來，當我們的電力系統全面轉向可再生能源，可再生能源配套的儲能電池規模將空前龐大。已經商業化的鋰電池技術面臨易燃易爆、循環壽命有限、成本高昂的問題，並不是大規模儲能系統的理想選擇。
