KERI researchers develop high-capacity Li-metal battery with improved rate performance and stability

Green Car Congress

A research team at Korea Electrotechnology Research Institute (KERI) has developed a high-capacity Li-metal battery with improved rate performance and stability using a one-dimensional Li-confinable porous hollow carbon host. However, these hosts suffer from unwanted Li growth on their surface (i.e., Kang et al.

New electrode material for solid-state batteries improves performance

Green Car Congress

A research team from Japan has recently developed a novel electrode material for all-solid-state batteries (ASSBs) by combining lithium sulfate and lithium ruthenate, which results in improved performance. However, they have never been applied to all-solid-state batteries. Credit: Atsushi Sakuda, Osaka Prefecture University.

UH, Toyota researchers develop new cathode and electrolyte for high-power Mg battery rivaling Li-ion

Green Car Congress

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered. The combination affords a Mg battery that delivers a specific power of up to 30.4?kW?kg —Dong et al.

Tohoku, UCLA team advance 4V-class metal-free organic Lithium-ion batteries; croconic acid cathode

Green Car Congress

A joint research team from Tohoku University and the University of California, Los Angeles (UCLA) has made a significant advance towards high-voltage metal-free lithium-ion batteries by using a small organic molecule: croconic acid. Increasing organic batteries’ voltage could lead to higher energy-density batteries.

Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. Na is comparable to graphite for standard lithium ion batteries. 100 to 150 mA h g ?
