Researchers use graphite positive electrodes in high-capacity rechargeable lithium/chlorine batteries

Green Car Congress

The high surface area and large pore volume of aCNS in the positive electrode facilitated NaCl or LiCl deposition and trapping of Cl 2 for reversible NaCl/Cl 2 or LiCl/Cl 2 redox reactions and battery discharge/charge cycling. This work could open up widely available, low-cost graphitic materials for high-capacity alkali metal/Cl 2 batteries.

Stanford team develops ultra-fast aluminum-ion battery with stability over thousands of cycles

Green Car Congress

A team at Stanford University, led by professor Hongjie Dai, has developed a high-performance, safe, fast-charging aluminum-ion battery that can last for thousands of cycles. The Al-ion battery—comprising an aluminum anode, graphite cathode and ionic liquid electrolyte—produces about half the voltage of a Li-ion battery.

Improving the Charge-Discharge Capacity and Cycleability of Carbon Electrodes for Li-ion Batteries

Green Car Congress

As one of the many approaches under investigation to increase the power density, specific capacity, and cyclic efficiency of rechargeable lithium-ion batteries, researchers are seeking to develop higher-capacity anode materials (such as silicon- or tin-based materials).
