New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Much recent research on batteries, including other work done by Cui’s research group, has focused on lithium-ion batteries, which have a high energy density; however, energy density really doesn’t matter for storage on the power grid. Cost is a greater concern. —Colin Wessells.

NETL investigating researching chemistries for large-scale battery- and supercapacitor-based grid energy storage systems

Green Car Congress

NETL researchers have synthesized Si-C (carbon fiber, carbon nanotube, carbon mattes, graphene) composite anodes. Most supercapacitor systems to date rely on carbon-based structures utilizing electrochemical double layer capacitance (EDLC) phenomenon based on charge transfer occurring from adsorbed species.

Report: sustainable batteries represent the best prospect for meeting Paris climate goals; requires $550B investment over 10 years

Green Car Congress

The report— A Vision for a Sustainable Battery Value Chain in 2030 —suggests that, with a concerted push to put the right conditions in place, batteries could enable a 30% reduction in carbon emissions in both the transport and power sectors. This would close the world’s existing energy access gap by 70%.
