The American start-up Enovix recently unveiled its next-generation silicon battery. Being able to be almost completely recharged in less than 10 minutes, it would allow electric vehicles incorporating it to be back on the road in a minimum of time.
Encourage the adoption of electric vehicles by reducing charging times
The charging times of batteries are an extremely important factor in encouraging the adoption of electric vehicles. In recent years, significant breakthroughs have been made to drastically reduce it. In 2021, researchers from Harvard had notably presented an experimental ultra-fast charge lithium-ion cell capable of self-regeneration.
The technology group ABB currently offers the world’s fastest electric vehicle charger capable of fully charging a car in 15 minutes or less. Enovix endeavors to reduce this delay thanks to its battery architecture in 3 dimensions » exclusive, which incorporates a cathode and a anode silicon.
With a significantly higher storage potential, silicon is favored as an alternative to graphite for anodes. According Enovixthe innovative architecture of its new battery increases its energy density tenfold and enables it to withstand more than 1,000 charge/discharge cycles while retaining 93% of its capacity.
A silicon battery reaching 80% charge in just over 5 minutes
In a recent series of tests, the company demonstrated that this type of silicon cell recharged to 80% in 5.2 minutesand reached 98% charge in less than 10 minutes. This is significantly better performance than the lithium-ion battery unveiled last month by Chinese researchers.
” Ultra-fast charging can accelerate the mass adoption of electric vehicles and we were able to demonstrate a level of performance exceeding the objectives of many manufacturers “, valued Harold RustCEO ofEnovix.
” We are proud to contribute to the electrification of the automotive industry and to demonstrate that our batteries are an attractive option to power this type of vehicle.. »
