Researchers in Korea propose graphene/Ni foam as Li metal storage medium for advanced batteries

Green Car Congress

Researchers in Korea have developed three-dimensional monolithic corrugated graphene on nickel foam electrode as a Li metal storage framework in carbonate electrolytes. Therefore, hybrid engineering to prevent dendritic Li growth and increase the coulombic efficiency in highly reactive electrolytes is essential. 2018.12.075.

MIT electrolyte enables ultra-high voltage Ni-rich cathodes in Li-metal batteries

Green Car Congress

MIT researchers and colleagues at two national laboratories have developed a sulfonamide-based electrolyte that enables stable cycling of a commercial LiNi 0.8 A limited cyclable Li inventory can be easily depleted by side reactions or become kinetically unreachable due to electronic/ionic isolation. —Jeremiah Johnson.

UNIST team develops new electrolyte additive for high-energy-density Li-ion batteries

Green Car Congress

Researchers at the Ulsan National Institute of Science and Technology (UNIST) in Korea have developed an innovative electrolyte additive that enables a high-energy-density Li-ion battery to retain more than 80% of its initial capacity even after hundreds of cycles. An open-access paper on their work is published in Nature Communications.

Roskill forecasts Li-ion battery demand to increase more than ten-fold by 2029 to >1,800GWh

Green Car Congress

Roskill forecasts that Li-ion battery demand will increase more than ten-fold by 2029, reaching in excess of 1,800GWh capacity. In the late 2020s, Li-ion technologies could see increasing competition from other battery technologies, though Li-ion cells are expected to maintain their dominant position, Roskill said.
