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.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. The high energy storage has stimulated a worldwide study of Li-air batteries. V was developed.

Univ. of Maryland team develops tin-film on wood fiber anode for Na-ion batteries; targeting grid storage

Green Car Congress

A team at the University of Maryland has demonstrated that a material consisting of a thin tin (Sn) film deposited on a hierarchical conductive wood fiber substrate is an effective anode for a sodium-ion (Na-ion) battery, and addresses some of the limitations of other Na-ion anodes such as capacity fade due to pulverization.
