Carmakers are perfecting a new form of solid-state battery technology designed to eliminate one of the chief concerns among prospective EV buyers – range anxiety.
oday’s electric cars, from the Tesla Model 3 saloon to Jaguar’s I-Pace crossover, are all powered by lithium-ion batteries. These cells, which have been around for decades, are relatively cheap to charge but can’t compete with the range of petrol or diesel cars, leaving EV owners anxious about running out of power between charging stations.
However, it will be a different story when the “miraculous” new solid-state battery technology makes its way into production cars, says Autocar.
What are solid-state batteries?
As the name suggests, solid-state batteries are composed of “solid lithium electrodes” set in rigid “conductive” material such as ceramic or a polymer, reports Alphr.
By contrast, conventional lithium-ion batteries use solid lithium electrodes and are encased in a “chemical electrolyte”.
So why are they better than lithium-ion batteries?
Replacing the wet electrolyte with a solid means that the new batteries should be easier to make – and therefore cheaper – than the lithium-ion versions, says Top Gear.
