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

GM researchers demonstrate hierarchical electrode architectures for high energy lithium-chalcogen rechargeable batteries

Green Car Congress

lithium-sulfur (Li-S) and lithium selenium (Li-Se) systems— are promising candidates for high energy electrical storage solution. It has now well recognized that excellent performance could be achieved with a low sulfur to carbon ratio and a low total S mass loading in the electrode. Lithium-chalcogen batteries—e.g.,

KAIST researchers develop nitrogen-doped carbon nanotubes for high-capacity Li-ion energy storage systems

Green Car Congress

Korean have developed nitrogen-doped carbon nanotubes for high-capacity lithium-ion energy storage systems, such as a lithium-ion capacitor. As an attempt to take only advantages of both types of ESSs, recently, lithium ion capacitors (LICs) have been designed and demonstrated. Credit: ACS, Shin et al. Click to enlarge.
