Fraunhofer researchers develop new low-cost dry-film electrode production process

Green Car Congress

Researchers at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed a new battery cell production process that coats the electrodes of the energy storage cells with a dry film instead of liquid chemicals. BroadBit uses it to produce new types of sodium-ion batteries. © Fraunhofer IWS.

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.

New cathode material for Li-S batteries: sulfur-anchored azulene

Green Car Congress

A team of researchers from China and Germany have used azulene—a benzene-free and vinyl-free molecule—to polymerize with sulfur to create a cathode material for Li-S batteries. Hence, it is urgent to develop new organosulfur polymers with high sulfur content as candidates for Li-S batteries. Chen et al.

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

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. 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.
