Brand New Green Battery Is a Breakthrough for Electric Vehicles

Researchers from Harvard University have developed a breakthrough battery for electric vehicles (EVs) that takes just three minutes to charge and lasts for 20 years. The average EV takes around eight hours to charge. For instance, the Chevrolet Bolt takes seven hours, while the Tesla Model S (Long Range) can take up to 12 hours. The idea of a battery that takes just minutes is an exciting development. It promises better results for car manufacturers, car owners, and car charging installations, which will eventually be available to the public on a large scale as petrol and diesel vehicles become a thing of the past. What is this battery made of, and when will it be consumer-ready?

The Secret Lies in the Lithium

The new battery is made of lithium metal and can be charged and discharged approximately 10,000 times. It differs from most current batteries in that the latter are made with lithium ion. The design is inspired by something totally inspiring – a classic American delight, the BLT sandwich! The game-changing design prevents the growth of dendrites – the spiky structures that accumulate on a battery’s anodes. They reduce the lifespan of batteries, negatively affect their ability to hold a charge, and can cause short-circuits, which can affect safety. Lithium ion batteries develop these dendrites and last only seven to eight years. They also have only 2,000 to 3,0000 charging cycles, even when they are in the best of class. The new lithium metal battery can be charged as usual. This is good news for public stations and home chargers alike. They also enable families to rely on one charger for all their vehicles. Typical home level 2 charging stations are used to recharge just one vehicle, since charging is a long process. As such, current batteries can be a setback for families wishing to have more than one EV.

Adden Energy Obtains the Exclusive Licence to Develop the Battery

Adden Energy, a startup co-funded by three of the new battery’s developers (Xin Li, William Fitzhugh, and Luhan Ye) will be entrusted with the further development of the new battery. They currently have plans to scale it up to a palm-sized pouch cell, and then to a full-scale battery. They expect to achieve this goal within three to five years, having recently closed a seed funding round of $5.15 million for this purpose. Xin Li recently told the press that in order to electrify vehicles on a large scale, solid-state batteries are the solution.

It’s an exciting time for Harvard academics and Adden Energy. The team are currently developing a new lithium-metal battery that differs considerably from lithium-ion batteries. The new battery is a revolutionary product that promises up to 10,000 charging cycles. It takes just minutes to charge, which is a big incentive for families with more than one vehicle or buyers who are currently put off by long charging times. It will also make public charging stations much more efficient and lucrative owing to its faster charging rate.
