Lithium batteries move lithium ions from the cathode to the anode during charging. The big challenge with lithium-metal batteries has always been chemistry. “By studying their fundamental thermodynamics, we can unlock superior performance and harness their abundant opportunities.” “Our research shows that the solid-state battery could be fundamentally different from the commercial liquid electrolyte lithium-ion battery,” said Li. Associate Professor Xin Li and his team have designed a stable, lithium-metal battery that can be charged and discharged at least 10,000 times. With its high current density, the battery could pave the way for electric vehicles that can fully charge within 10 to 20 minutes. This battery technology could increase the lifetime of electric vehicles to that of the gasoline cars - 10 to 15 years - without the need to replace the battery. The researchers paired the new design with a commercial high energy density cathode material. Now, Li and his team have designed a stable, lithium-metal, solid-state battery that can be charged and discharged at least 10,000 times - far more cycles than have been previously demonstrated - at a high current density. “But the stability of these batteries has always been poor.” Paulson School of Engineering and Applied Science (SEAS). “A lithium-metal battery is considered the holy grail for battery chemistry because of its high capacity and energy density,” said Xin Li, associate professor of materials science at the Harvard John A. Week Ahead on TV: 'Jhalak.Long-lasting, quick-charging batteries are essential to the expansion of the electric vehicle market, but today’s lithium-ion batteries fall short of what’s needed - they’re too heavy, too expensive and take too long to charge.įor decades, researchers have tried to harness the potential of solid-state, lithium-metal batteries, which hold substantially more energy in the same volume and charge in a fraction of the time compared to traditional lithium-ion batteries. Shared Recently! With no party likely to get a majority, who will align with whom is the big question Harvard-backed startup develops EV battery tech with over 10K cycles IANS 03 September 2022 Post Your Comments We defeat the growth of dendrites before they can cause damage, by novel structural and material designs,' said Luhan Ye, CTO of Adden Energy.Īs a result, the device can sustain its high performance over a long lifetime, he added. 'Typically, lithium-metal anodes in other solid-state designs develop dendrites, twig-like growths that can gradually penetrate through the electrolyte to the cathode. The technology developed at Harvard, which includes core innovations in solid-state battery design and electrolyte production methods, may offer other crucial advantages. 'We set out to commercialise this technology because we do see our technology as unique compared to other solid-state batteries,' he added.

'If you want to electrify vehicles, a solid-state battery is the way to go,' said Li. The startup aims to scale the battery up to a palm-sized pouch cell, and then upward toward a full-scale vehicle battery in the next three to five years.

The license and the venture funding will enable the startup to scale Harvard's laboratory prototype toward commercial deployment of a solid-state lithium-metal battery that may provide reliable and fast charging for future EVs to help bring them into the mass market. Harvard's Office of Technology Development has now granted an exclusive technology license to Adden Energy.Īdden Energy has closed a seed round with $5.15 million in funding led by Primavera Capital Group, with participation by Rhapsody Venture Partners and MassVentures. The battery also offers high energy density and a level of material stability that overcomes the safety challenges posed by some other lithium batteries, according to results published in Nature and other journals. Paulson School of Engineering and Applied Sciences (SEAS). That could be a game changer,' said Xin Li, associate professor of materials science at Harvard John A. 'We have achieved in the lab 5,000 to 10,000 charge cycles in a battery's lifetime, compared with 2,000 to 3,000 charging cycles for even the best in class now, and we don't see any fundamental limit to scaling up our battery technology.

The startup has now been granted technology license from Harvard University to scale innovative lithium-metal battery technology for commercial deployment. New York, Sep 3: US-based startup Adden Energy has achieved solid-state battery charge rates as fast as three minutes with over 10,000 cycles in a lifetime in lab settings.
