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

Green Car Congress

The resulting 12-sided carbon nanospheres had “bumpy” surfaces that demonstrated excellent electrical charge transfer capabilities. The material exhibits a high reversible capacity of 624 mAh g –1 with an 85.9% capacity retention at 0.1 A g –1 as the temperature drops to ?20 Even if the temperature drops to ?35

Volvo C40 Recharge LCA highlights huge potential of manufacturing and charging EVs with clean energy

Green Car Congress

Volvo Cars has published a lifecycle analysis report on its second fully electric car, the C40 Recharge, which shows the potential CO 2 reductions if a car is built and charged using clean energy sources. However, a significantly lower carbon footprint is achieved when charging the car with renewable electricity, such as wind power.

Roskill sees recovery in lithium industry, buoyed by demand from rechargeable battery applications

Green Car Congress

In 2019, monthly average lithium carbonate prices fell 36% between January and December. Q1 2020 saw monthly average prices fall further to less than US$7,000/t Li 2 CO 3 for the first time since 2014, eroding price increases caused by forecast strong demand growth in the lithium-ion battery industry and uncertainty over future supply.

Carbon nanomembrane prevents dendrite formation in Li-metal batteries, doubles lifetime

Green Car Congress

The energy density of traditional lithium-ion batteries is approaching a saturation point that cannot meet the demands of the future—in electric vehicles, for example. Lithium metal batteries can provide double the energy per unit weight when compared to lithium-ion batteries. Here, the use of an ultrathin (?1.2
