KERI researchers develop high-capacity Li-metal battery with improved rate performance and stability

Green Car Congress

A research team at Korea Electrotechnology Research Institute (KERI) has developed a high-capacity Li-metal battery with improved rate performance and stability using a one-dimensional Li-confinable porous hollow carbon host. However, these hosts suffer from unwanted Li growth on their surface (i.e., Kang et al.

Purdue team uses pollen grains as basis for carbon architectures for Li-ion anodes

Green Car Congress

A team at Purdue University has used pollens as the basis for carbon architectures for anodes in energy storage devices. Currently, Li-ion batteries generally use graphite as the anode material, with a theoretical capacity of 372 mAh/g and excellent capacity retention over extended cycling.

Study links carbon fiber microstructure to Li insertion mechanism in structural batteries

Green Car Congress

Carbon fibers have already beeen demonstrated as high-capacity Li-ion battery anodes, opening the way for their use as structural electrodes—i.e., simultaneously carrying mechanical load and storing electrical energy. There is therefore some potential here for carbon fiber manufacturers to extend their utilisation.
