New York, Sep 3 : A startup in the US called Adden Energy has achieved solid-state battery charge rates up to three minutes with more than 10,000 cycles in the course of a lifetime in laboratory settings.The startup has been granted a technology license by Harvard University to scale innovative lithium-metal battery technology for commercial use.
“We have accomplished in the lab between 5,000 and 10,000 charging cycles in the lifetime of a battery which is in contrast with the 2,000-3,000 charge cycles for the most advanced in class right now and we don’t think there is any fundamental limitation to advancing the battery technology we have developed.It could be an important game changer,” said Xin Li the associate professor of materials science at the Harvard John A.Paulson School of Engineering and Applied Sciences (SEAS).
The battery also provides high energy density and a degree of stability that is superior to the security issues that are posed by others lithium batteries as per findings reported in Nature and various other journals.
The Harvard’s Office of Technology Development has granted an exclusive technology license to Adden Energy.
Adden Energy has closed a seed round with $5.15 million in capital which was led by Primavera Capital Group, with participation from Rhapsody Venture Partners as well as MassVentures.
The license and venture capital will allow the startup to expand the Harvard lab prototype to commercial deployment of a lithium-metal-based solid-state battery that could offer reliable and fast charging to future EVs to assist in their introduction into the mainstream market.
The company’s goal is to expand the battery to a small pouch cell and then move it up to the full-size car battery in the next three to five years.
“If you are looking to electrify your vehicle using a solid-state battery, this is the best choice,” said Li.
“We have set out to commercialize this technology since we believe that our technology is distinct from other solid-state batteries” he added.
The technology created at Harvard and Harvard, which includes key innovations in the design of solid-state batteries and electrolyte production techniques, could provide additional advantages.
“Typically lithium-metal anodes in other solid-state designs form dendrites.These are twig-like structures that slowly penetrate the electrolyte and reach the cathode.
We can stop the development of dendrites, before they could cause damage through our innovative materials and structural designs,” said Luhan Ye CTO of Adden Energy.
In the end, the device can maintain its performance for the course of its life, he added.
