Researchers from the Cockrell School of Engineering at The University of Texas at Austin have developed a cobalt-free high-energy lithium-ion battery, eliminating the cobalt and opening the door to reducing the costs of producing batteries while boosting performance in some ways. More nickel in a battery means it can store more energy.

A team at Stanford University has developed stable silicon Li-ion battery anodes by incorporating a conducting polymer hydrogel into the Si-based material. A g -1 , the composite electrode exhibited a relatively stable reversible lithium capacity of 1,600 mAh g -1 for 1,000 deep cycles based on the weight of only Si.
