Korean researchers have ushered in a new era for electric vehicle (EV) battery technology by solving the long-standing dendrite problem in lithium-metal batteries. While conventional lithium-ion batteries are limited to a maximum range of 600 km, the new battery can achieve a range of 800 km on a single charge, a lifespan of over 300,000 km, and a super-fast charging time of just 12 minutes.

A research team from the Frontier Research Laboratory (FRL), a joint project between Professor Hee Tak Kim from the Department of Chemical and Biomolecular Engineering, and LG Energy Solution, has developed a “cohesion-inhibiting new liquid electrolyte” original technology that can dramatically increase the performance of lithium-metal batteries...

Graphene-Nanotube Hybrid boosts Lithium Metal Batteries

1. Lithium metal coats the hybrid graphene and carbon nanotube anode in a battery created at Rice University. The lithium metal coats the three-dimensional structure of the anode and avoids forming dendrites. Courtesy of the Tour Group. 2. A graphic shows carbon nanotubes covalently bonded to a graphene substrate. The material created at Rice University is being tested as an anode for high-capacity lithium metal batteries.

An electron microscope image shows a carbon nanotube evenly coated with lithium metal. Tests on the graphene-carbon nanotube anode created at Rice University show it resists the formation of lithium dendrites that can damage batteries. Courtesy of the Tour Group
