GM researchers demonstrate hierarchical electrode architectures for high energy lithium-chalcogen rechargeable batteries

Green Car Congress

lithium-sulfur (Li-S) and lithium selenium (Li-Se) systems— are promising candidates for high energy electrical storage solution. A corresponding chalcogen cathode structure, which is composed of a chalcogen element (S or Se), a conductive framework, and a polymer binder, is well-accepted for most studies.

Purdue team uses pollen grains as basis for carbon architectures for Li-ion anodes

Green Car Congress

A team at Purdue University has used pollens as the basis for carbon architectures for anodes in energy storage devices. Currently, Li-ion batteries generally use graphite as the anode material, with a theoretical capacity of 372 mAh/g and excellent capacity retention over extended cycling. —Vilas Pol. The work is ongoing.

ETH Zurich team shows vanadate-borate glasses as inexpensive high-capacity cathodes for Li-ion batteries

Green Car Congress

A team from ETH Zurich in Switzerland has demonstrated the use of vanadate-borate glasses (Li 2 O-B 2 O 3 -V 2 O 5 , referred to as V 2 O 5-LiBO 2 ) as high-capacity cathode materials for rechargeable Li-ion batteries for the first time. Subsequent quenching to room temperature produces the glass material. Batteries'
