Team develops a commercially viable and safe gel electrolyte for lithium batteries. Professor Soojin Park, Seoha Nam, a PhD candidate, and Dr. Hye Bin Son from the Department of Chemistry at Pohang University of Science and Technology (POSTECH) have achieved a breakthrough in creating a gel electrolyte-based battery that is both stable and commercially viable. Their research was recently published in the international journal Small.

Lithium-ion batteries are extensively utilized in portable electronics and energy storage including electric vehicles. However, the liquid electrolytes used in these batteries pose a significant risk of fire and explosion, prompting ongoing research efforts to find safer alternatives...

When an electric vehicle is parked outside, its temperature can swing wildly from day to night and season to season, which can lead to deterioration of the battery. To dampen these fluctuations and extend the battery’s lifespan, researchers have designed an all-season thermal cloak that can cool an electric vehicle by 8°C on a hot day and warm it by 6.8°C at night...

Significantly improved electric vehicle (EV) batteries could be a step closer thanks to a new study led by University of Oxford researchers, published today in Nature. Using advanced imaging techniques, this revealed mechanisms which cause lithium metal solid-state batteries (Li-SSBs) to fail. If these can be overcome, solid-state batteries using lithium metal anodes could deliver a step-change improvement in EV battery range, safety and performance, and help advance electrically powered aviation.

One of the co-lead authors of the study Dominic Melvin, a PhD student in the University of Oxford’s Department of Materials, said: ‘Progressing solid-state batteries with lithium metal anodes is one of the most important challenges facing the advancement of battery technologies...
