Researchers investigate effect of impact on structurally-embedded Li-ion batteries

Green Car Congress

Researchers in China are investigating the effect of low-velocity impact loads on structurally embedded Li-ion batteries in vehicles. —Li et al. The researchers found that embedded batteries experienced micro short circuits during impact-loading process and kept good energy-storage capacity after transient impact.

Li-Cycle sets up its first US-based Li-ion battery recycling center in NY state

Green Car Congress

Empire State Development (ESD) announced that Canada-based Li-Cycle Corporation will establish its first US-based Li-ion battery recycling facility in New York State. Li-Cycle expects to be fully operational at the facility later this year. The technology can do so with a recovery rate of 80 – 100% of all materials.

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. . …

Researchers develop real-time picture of formation of solid–electrolyte interphase of a Li-ion battery

Green Car Congress

During the first charging process of a new Li-ion battery cell, trace amounts of electrolyte components decompose sacrificially to form what is called a solid–electrolyte interphase (SEI) on the anode surface. The inner SEI is continuous, dense and impermeable to electrolytes, and it is most probably composed of Li 2 O.
