Novel copolymer binder extends the life of lithium-ion batteries

Green Car Congress

One of the major causes for the drop in capacity over time in Li-ion batteries is the degradation of the widely used graphite anodes. This study was supported by the JST-Mirai Program (grant umber JP18077239). Graphite thus requires a binder to prevent it from falling apart with use. 0c02742.

Saft team develops first metal hydride - sulfur Li-ion battery

Green Car Congress

Lithium-sulfur (Li-S) batteries are one of the most attractive candidates for the next generation of high-energy rechargeable Li batteries because of their high specific energy at a working voltage of ca. V vs. Li + /Li. V vs. Li + /Li, respectively. V vs Li=Li +.

NTU Singapore team develops ultra-fast charging Li-ion battery with new TiO2 gel anode material

Green Car Congress

Researchers from Nanyang Technological University (NTU Singapore) led by Professor Xiaodong Chen have developed a new TiO 2 gel material for Li-ion battery anodes. A battery equipped with the new anode material can be recharged up to 70% in only 2 minutes. A paper on their work is published in the journal Advanced Materials.

Univ. of Missouri team progressing with convection battery; enabling rechargeable lithium-metal batteries

Green Car Congress

The Li / Support is the electrode made possible with the convection battery technology. The technology allows lithium-metal batteries to be recharged without the dendrite failure (short circuit) that has prevented rechargeable lithium-metal batteries from being commercially viable.

PATHION develops new LiRAP-based solid-state electrolytes for Li-sulfur and sodium-ion batteries

Green Car Congress

At the Spring 2015 Materials Research Conference in San Francisco earlier this month, PATHION presented two new derivative superionic solid-state electrolytes built upon LiRAP (Lithium-Rich Anti-Perovskite). PATHION is working on a derivative for Li-sulfur batteries as well as a derivative that could be applied in a sodium-ion battery.

24M emerges from stealth mode with new semi-solid Li-ion cell; <$100/kWh by 2020

Green Car Congress

Stealth-mode battery start-up 24M has introduced its new semi-solid lithium-ion cell. Together, our inventions achieve what lithium-ion has yet to do—meet the ultra-low cost targets of the grid and transportation industries. The lithium-ion battery is a brilliant, enabling technology, but its economics are flawed.
