Researchers in Belgium develop new class of solid composite electrolytes for Li-ion batteries: Eutectogels

Green Car Congress

Researchers at Hasselt University in Belgium are proposing a new class of solid composite electrolytes (SCEs) for Li-ion batteries: deep eutectic solvent (DES)–silica composites. Structural schematic of a Li/LFP cell with the ETG as electrolyte. V versus Li, and unable to stop the growth of lithium dendrites.

CMU study suggests difficulties in reaching targeted low price points for Li-ion batteries

Green Car Congress

Even in the most optimistic scenario, when the cells are the largest (20720), electrodes the thickest (100 mm), and the production volume is 8 GWh per year, the cost per kWh for LMO cells is well above the DOE target. Historical prices and future cost predictions for lithium-ion batteries.

Researchers fabricate high-performance 3D silicon anodes for Li-ion batteries from reed leaves

Green Car Congress

Nanoporous silicon is considered an attractive next-generation anode material in lithium-ion batteries due to its much higher theoretical capacity and lower operating voltage than the commonly used graphitic carbon materials. Even after 4,000 cycles and at a rate of 10C, the anode achieved a specific capacity of 420 mAhg -1. —Liu et al.
