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

Green Car Congress

This work could open up widely available, low-cost graphitic materials for high-capacity alkali metal/Cl 2 batteries. The new study found that the evolution of graphite over battery cycling, including intercalation/deintercalation and exfoliation, generated sufficient pores for hosting LiCl/Cl 2 redox. 2c07826.

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

Green Car Congress

We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames. An ultrafast rechargeable aluminum-ion battery,” Nature. —Prof. Resources. “An

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).
