Solid-state battery: Adden Energy produces sample cells for OEMs
Adden Energy says it is already taking orders from car manufacturers and other customers who want the first solid-state cells for validation. These sample pouch cells are now being produced on a newly inaugurated pilot line that Adden Energy has set up in Waltham, Massachusetts. The Americans want to make solid-state batteries based on lithium metal ready for the market and claim that they can “double the driving range while cutting the charge-times to as fast as gas.”
In addition to the performance of the batteries, Adden Energy also attaches importance to the fact that solid-state batteries can be built in existing production facilities. With this in mind, the company explains that it has developed a process to produce these next-generation batteries using “conventional, readily available manufacturing equipment.” The new pilot line is said to prove that. It should reach its full production rate in the summer.
“Our initial prototypes had already shown 50% improvement in energy density over current lithium-ion technology with the added benefits of charging in under 10 minutes and being non-flammable,” said Adden Energy Chief Product Officer Dr. Pu Zhang. “Now we have shown we can manufacture these batteries on the same equipment that is commonly used for lithium-ion production, which gives us a clear route to scale-up and manufacturing.”
Adden Energy first made a name for itself as a Harvard University spin-off in 2022. The startup received a technology license and closed a seed financing round of 5.15 million dollars at that time. Adden Energy also attracted attention with the statement that its self-developed lithium-metal battery had a charging time of just three minutes in the laboratory and a service life of more than 10,000 cycles. However, this was still a pre-development stage for an automotive battery.
