To protect the marine ecological environment and facilitate the sustainable development of the marine economy in Hong Kong, a CityU-led marine research team has developed a new aquaculture technique by establishing a floating, indoor weatherproof fish farm with a seawater recirculating system to replace conventional fish rafts.

A joint research team co-led by a scientist from City University of Hong Kong (CityU) has developed a much more stable, manganese-based cathode material. The new material has higher capacity and is more durable than the existing cobalt and nickel cathode materials - 90% of capacity is retained even when the number of charging-recharging cycles doubled.
