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.

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

Researchers use graphite positive electrodes in high-capacity rechargeable lithium/chlorine batteries

Green Car Congress

The high surface area and large pore volume of aCNS in the positive electrode facilitated NaCl or LiCl deposition and trapping of Cl 2 for reversible NaCl/Cl 2 or LiCl/Cl 2 redox reactions and battery discharge/charge cycling. The study is published in the Journal of the American Chemical Society. 2c07826.

ORNL researchers develop new electrolyte for extreme fast charging

Green Car Congress

Researchers from Oak Ridge National Laboratory (ORNL) and colleagues have developed a novel high-performance electrolyte (HPE) consisting of lithium bis(fluorosulfonyl)imide (LiFSI), lithium hexafluorophosphate (LiPF 6 ) and carbonates to support extreme fast charging (XFC). The cell recharged 80% of its capacity in 10 minutes.

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
