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. C and fast charging capability (1.9% O 2 cathodes. —Park et al.

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).

Stanford researchers develop new electrolysis system to split seawater into hydrogen and oxygen

Green Car Congress

Negatively charged chloride in seawater salt can corrode the anode, however, limiting the system’s lifespan. The researchers discovered that if they coated the anode with layers that were rich in negative charges, the layers repelled chloride and slowed down the decay of the underlying metal. to 1 A/cm 2 ) over 1,000 h. 1900556116.
