Chinese researchers develop calcium-ion battery breakthrough
Chinese researchers have developed a new calcium-ion-based battery with more capacity and a longer life cycling life than current lithium-ion batteries. The new battery was developed by a team from the Shenzhen Institute of Advanced Technology at the Chinese Academy of Sciences.
The battery offers more capacity, because a calcium-ion can provide twice the number of electrons than lithium-ion. Also, calcium is about 2,500 times as common than lithium. According to the Shanghai Daily, high performance and low-cost calcium-ion energy storage technology can be promising candidate to replace lithium-ion.
The challenge until now was to find an appropriate combination of electrode materials and electrolytes. The new device has overcome this major obstacle, by using activated carbon as a positive electrode and tin as a negative electrode.
