A vital component required for lithium-ion battery fast charging has been found by researchers at the University of Tennessee in Knoxville.
The commercially viable method creates a potential route for enhancing electric vehicle charging rates.
The nation's portfolio of renewable energy technologies must include lithium-ion batteries, or LIBs. The majority of all-electric and hybrid vehicles employ LIBs.
Because they can store more energy, charge more quickly, and last longer than conventional lead-acid batteries.
The group found a unique molybdenum-tungsten-niobate (MWNO) compound with quick rechargeability and excellent efficiency.
This may eventually take the role of graphite in industrial batteries.
The fact that the electrolyte breaks down and builds up on the electrode surfaces while being charged is a barrier for graphite anodes.
This accumulation can reduce the stability and performance of batteries by slowing the mobility of lithium ions.
The traditional method of making niobium oxides, such as MWNO, over an open flame uses a lot of energy and produces poisonous waste.
The success of the material is largely due to its nanoporous structure, which offers improved electrical conductivity.
