S. Korean researchers unveil lithium replacement for EV battery cathode that increases range

The research team at Gwangju Institute of Science and Technology has developed a high-performing lithium metal battery with higher energy storage capacity that can extend the driving distance of electric vehicles by enabling the realization of.

The new lithium battery’s capacity is about 1.5 times higher than the existing ones due to the use of vanadium oxide as a cathode material.

The vanadium oxide’s capacity is about 1.5 to 2 times higher than that of existing transition metal oxide, but its collapsible structure during the battery charging and discharging process results in low electron and ion conductivity.
.
Consequently, the electrochemical reaction is slower.

The research team developed a nanoplate-layered vanadium oxide cathode material using a new synthetic method to address vanadium oxide’s shortcomings.
