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

Researchers at the Ulsan National Institute of Science and Technology (UNIST) in Korea say they have developed an 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. In a paper published in Nature Communications, the scientists reported that when the substance was… Read more »

South Korean team develops coated LMO cathode that lasts longer at high temperatures

The quest for the better battery involves ongoing research on improving and optimizing materials used for lithium-ion cells. One such material is LiMn2O4 (LMO), which offers high power and low cost, but cell life at high temperatures can be problematic. In a paper in Nano Letters, a team from the Ulsan National Institute of Science… Read more »

Single-crystal nanoparticles increase battery charging speed by 30 times [corrected]

The rush for a better battery is in full swing – every week seems to bring news of a new breakthrough, or at least a promising avenue of research. While most researchers concentrate on increasing energy density, and a few on improving thermal performance, a group of Korean scientists is attacking the issue of charging… Read more »
