Researchers convert spent asphalt to mesoporous carbon anode material for Li/Na/K-ion batteries

Green Car Congress

Researchers at Changsha University of Science & Technology in China have used spent asphalt to produce a high-performance universal Li/Na/K-ion anode material. As an anode material for Li-ion batteries, the mesoporous carbon exhibits a reversible capability of 674.2 —Xie et al. 2021.230593.

UVA researchers devise method for converting retired Li-ion anodes to graphene and GO

Green Car Congress

Researchers at the University of Virginia (UVA) have devised a process for converting retired Li-ion battery anodes to graphene and graphene oxide (GO). So far, only 1% of end-of-life Li-ion batteries have been recycled. Here, graphite powders from end-of-life Li-ion battery anodes were used to fabricate graphene.

New smelting reduction process to recover Co, Ni, Mn, and Li simultaneously from Li-ion batteries

Green Car Congress

A team from metals research institute SWERIM in Sweden reports on a smelting reduction process to recover cobalt, nickel, manganese and lithium simultaneously from spent Li-ion batteries. The presence of slag may retain some Co, Ni, Mn, and Li in the slag due to the inherent nature of the slag. —Hu et al. 2020.228936.

Proterial developed a technology that reduces CO2 emissions during Li-ion cathode material production by more than 20%

Green Car Congress

formerly Hitachi Metals, earlier post ) has developed a technology to manufacture cathode materials for lithium-ion batteries (LIBs) without the previously required process of converting nickel to nickel hydroxide(Ni(OH) 2 ) to produce a precursor that is used as the starting material for the manufacture of cathode materials.

PNNL team develops carbon nanotube-silicon microspheres as high-performance Li-ion anodes

Green Car Congress

Silicon is an appealing anode material for Li-ion batteries because it can hold about 10 times the electrical charge per gram compared to graphite. Then we used aluminum and higher heat to convert the silicon oxide into silicon, followed by immersion in water and acid to remove by-products. —Xiaolin Li.
