Breakthrough flow batteries drive safe and low-cost energy storage

Professor Lo Yee-kwan's team at CUHK has developed a new flow battery technology. Compared with the currently commonly used lithium-ion batteries, this new battery uses sulfur, which is abundant and low-cost on Earth, as its core material. Combined with a water-soluble electrolyte, it not only eliminates the risk of fire, but is also expected to significantly reduce costs.

Currently, this technology has been applied to charging piles in mainland China, helping users save nearly 70% of their electricity bills. In the future, it will also be applied in renewable energy storage and high-computing data centers to promote carbon neutrality goals locally and globally.

This project was selected for the Hong Kong Government's second round “Industry-University-Research 1 Program” (RAISe). The program aims to unlock the potential of local universities to transform and commercialize scientific research results, and promote relevant cooperation among government, industry, universities and the scientific research community. We will introduce other CUHK selected projects in succession, please pay attention.
