UNIST team develops new electrolyte additive for high-energy-density Li-ion batteries

Green Car Congress

Researchers at the Ulsan National Institute of Science and Technology (UNIST) in Korea have developed an innovative electrolyte additive that enables a high-energy-density Li-ion battery to retain more than 80% of its initial capacity even after hundreds of cycles. The amount of metal inside the anode determines the battery capacity.

Argonne researchers use X-rays to understand the flaws of speedy charging

Green Car Congress

A team at Argonne National Laboratory has used spatially resolved energy dispersive X-ray diffraction to obtain a “movie” of lithiation and delithiation in different sections of a Li-ion battery cell and to quantify lithium gradients that develop in a porous graphite electrode during cycling at a 1C rate (full discharge in 1 hour).
