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.

Study sees gradual, focused replacement of lead-acid SLI batteries by Li-ion batteries over next couple of years

Green Car Congress

A study by a team of researchers from Germany and South Africa forsees the gradual replacement of lead-acid SLI (starter, lighting and ignition) batteries with Li-ion batteries over the next couple of years. That will see an uptake of more hybrid-, plug-in hybrids and BEVs in the EU.
