New multifunctional polymer binder achieves theoretical capacity of LiFePO4 Li-ion batteries without additives

Green Car Congress

Researchers led by a team from Griffith University in Australia have developed a multifunctional polymer binder that not only maintains the outstanding binding capabilities of sodium alginate but also enhances the mechanical integrity and lithium-ion diffusion coefficient in a LiFePO 4 (LFP) electrode during the operation of the batteries.

U Waterloo team identifies key reaction in sodium-air batteries; implications for improving Li-air

Green Car Congress

Chemists at the University of Waterloo have identified the key reaction that takes place in sodium-air batteries. Understanding how sodium-oxygen batteries work has implications for developing the more powerful lithium-oxygen battery, which has been proposed by some as the “holy grail” of electrochemical energy storage.
