Adden Energy develop EV car batteries that charge fully in 3 minutes

The new battery is made of lithium metal, instead of the lithium-ion found in EV cars

Havard-backed start-up Adden Energy has developed a battery for EV cars that is capable of being fully charged in three minutes and has a lifespan of around 20 years. This is more than twice that of the current EV batteries. The technology used by them in EV batteries has received a special license from Harvard's office of technology development.  The Massachusetts -based startup received $5.15 million in funding from the Primavera Capital Group along with MassVentures and Rhapsody Venture Partners.

The new battery is made of lithium metal, instead of the lithium-ion found in EV cars. According to researchers, the battery has an intricate design inspired by a BLT sandwich, which tends to prevent the growth of dendrites that grow in lithium-metal batteries and reduce their lifespan. This BLT design prevents the penetration of lithium dendrites by controlling and containing them. The battery is also self-healing which means its design and chemistry allow it to backfill holes created by dendrites. Now, Adden Energy will advance the technology as they have achieved 5,000 to 10,000 charge cycles in a battery’s lifetime compared to 2.000 to 3,000 charging cycles of traditional EV batteries.
