A very powerful battery for electric vehicles has been developed

A startup from Massachusetts has already received a license for large-scale production of a battery.

Harvard researchers have created a unique battery inspired by the BLT sandwich. The new electric car battery charges in three minutes and lasts 20 years, more than twice that of current car batteries.

The battery, developed by Harvard scientists, is lithium metal, not the lithium ion used in electric vehicles on the market. Lithium metal battery can be charged and discharged 10,000 times.

The startup’s goal is to scale a battery in a palm-sized cell bag, its components encapsulated in an aluminum-coated film.

Currently, electric vehicles contain lithium-ion batteries, which degrade over time and last up to seven to eight years, depending on how often they are used – similar to a smartphone battery . They are used in Tesla and other electric cars, as well as in laptops and smartphones.

“In the lab we have achieved 5,000 to 10,000 charge cycles over the life of a battery, compared to 2,000 to 3,000 charge cycles for even the best in class today, and we don’t see any major limitations on scaling our battery life.” technology,” the company said.

Its chemical composition allows you to fill the holes created by dendrites.

“Typically, lithium metal anodes in other solid state designs form dendrites, twig-like growths that can gradually penetrate the electrolyte toward the cathode. We stop the growth of dendrites before they can cause damage. with new designs and materials. As a result, the device can maintain its high performance over a long service life. Our recent study shows that this impressive feature can be maintained even when scaled up.”

Recall that early Korean engineers demonstrated the latest technology in which electric vehicles can be charged to 80% in just five minutes.

Experts say which electric cars drain batteries faster
