New aqueous rechargeable lithium battery shows good safety, high reliability, high energy density and low cost; another post Li-ion alternative

Green Car Congress

The battery, which can be low cost and reliable in terms of safety, provides another chemistry for post Li-ion batteries, they suggest, and with higher practical energy densities than Li-air systems for supporting applications including electric vehicles and large-scale grid energy storage. —Wang et al.

St. Andrews team elucidates behavior of carbon cathodes in Li-air batteries; the importance of the synergy between electrode and electrolyte

Green Car Congress

Carbon is seen as an attractive potential cathode material for aprotic (non-aqueous) Lithium-air batteries, which are themselves of great interest for applications such as in electric vehicles because of the cells’ high theoretical specific energy. Given the role of carbon as a possible porous positive electrode for nonaqueous Li?O

PNNL licenses three technologies via Startup America; batteries, fuel cells and buildings

Green Car Congress

Vorbeck, a manufacturer and developer of applications using its proprietary graphene material ( earlier post ), optioned the technology for use in a graphene-based electrode for lithium-air and lithium-sulfur batteries. PEM fuel cells are primarily used for backup power.

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

The critical barrier to wider deployment of electric vehicles is the high cost and low energy of today’s batteries. This ARPA-E program seeks to develop a new generation of ultra-high energy density, low-cost battery technologies for long range plug-in hybrid and all-electric vehicles.
