An energy storage company will begin mass producing an eco friendly alternative to at least one fossil fuel.
Adden Energy is preparing a commercially deploy solid-state battery systems for electric vehicles (EVs) that can be recharged up to 400 times faster than conventional units.
A lab scale, coin-cell prototype has already been developed at Harvard University’s John A. Paulson School of Engineering and Applied Sciences.
The research team, led by materials science associate professor Xin Li, confirmed the lithium-metal battery completely recharged in as little as three minutes – about the time it takes to refuel a diesel-powered light vehicle. This is significantly faster than conventional recharging cycles that last between 10 and 24 hours.
“Complete electrification of the vehicle fleet is one of the most meaningful steps we can take to fight climate change,” Adden CEO William Fitzhugh said in a public statement.
“EVs need to recharge at comparable times to internal combustion vehicles, essentially in the time you would currently spend at the gas pump.”
The battery can be recharged up to 10,000 times throughout its lifespan, allowing the technology to be used for more than a decade before a replacement is required. This is because the unit uses a “novel structural and material” design to defeat dendrite growth that penetrates and damages cathodes in conventional batteries.
“As a result the device can sustain its high performance over a long lifetime. Our recent study shows that this nice feature can also be maintained at scale-up,” Adden chief technology officer Luhan Ye said.
Primavera Capital Group, Rhapsody Venture Partners and MassVentures have approved US$5.15 million (A$7.91M) in seed round financing. An exclusive technology license has also been granted by the university’s office of technology development.
A full scale vehicle-sized battery is expected to take three to five years to develop.
