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. . … —Lu et al.

Argonne researchers identify another reason why fast-charging degrades the performance of Li-ion batteries

Green Car Congress

A new study by researchers from Argonne National Laboratory and the University of Illinois Urbana-Champaign seeking to identify the reasons that cause the performance of fast-charged lithium-ion batteries to degrade in EVs has found interesting chemical behavior of the anode as the battery is charged and discharged.

New approach to recover anode materials from spent Li-ion batteries

Green Car Congress

A team from Shandong University of Technology in China has proposed a new process to recycle anode materials from spent lithium-ion batteries and to reuse the graphite. The copper foil can be directly reused without further treatment, the Cu 2+ and Li + in the electrolyte can be recovered by precipitation. C are 427.81

UH, Toyota researchers develop new cathode and electrolyte for high-power Mg battery rivaling Li-ion

Green Car Congress

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered. The combination affords a Mg battery that delivers a specific power of up to 30.4?kW?kg —Dong et al.
