Researchers use carbon-based anodes with “bumpy” surfaces for Li-ion batteries that last longer in extreme cold

Green Car Congress

the key to addressing the low-temperature capacity loss lies in adjusting the surface electron configurations of the carbon anode to reinforce the coordinate interaction between the solvated Li + and adsorption sites for Li + desolvation and reduce the activation energy of the charge-transfer process.

Direct electro-oxidation method for lithium leaching from spent ternary Li-ion batteries

Green Car Congress

Researchers from Nanchang Hangkong University in China have developed a direct electro-oxidation method for lithium leaching from spent ternary lithium-ion batteries (T-LIBs) (Li 0.8 In a paper in the ACS journal Environmental Science & Technology they report that 95.02% of Li in the spent T-LIBs was leached under 2.5

U Michigan study finds cracking in Li-ion batteries speeds up EV charging

Green Car Congress

Rather than being solely detrimental, cracks in the cathodes of lithium-ion batteries reduce battery charge time, according to research done at the University of Michigan. This runs counter to the view of many electric vehicle manufacturers, which try to minimize cracking because it decreases battery longevity.

Roskill: Niobium industry looking for a future beyond steel; Li-ion batteries a possibility

Green Car Congress

Niobium consumption is driven by GDP but also by the regulatory environment as microalloying enhances construction safety. Niobium and batteries. As one of the indications of industry interest in the potential for niobium and batteries, the topic of the Charles Hatchett Award Seminar 2019 was the opportunity for niobium in batteries.

SLAC, Stanford researchers use cryo-EM to make first high-res images of wet SEI of Li-ion battery

Green Car Congress

Researchers from the Department of Energy’s SLAC National Accelerator Laboratory (SLAC) and Stanford University have made the first clear, detailed images of the solid-electrolyte interphase (SEI) layer in the wet environment of a working Li-ion battery by using cryogenic electron microscopy (cryo-EM).

Researchers designs new deep eutectic solvent to recover valuable elements from spent LNCM batteries

Green Car Congress

A team from Central South University in China has developed a new type of deep eutectic solvent (DES) that can efficiently leach metal elements from spent Ni-Co-Mn lithium-ion batteries (LNCM). The leaching rates of Ni, Co, Mn, and Li can all reach 99% under the conditions of T=140°C, t=10 min and no reductant.
