Adden Energy has commissioned an advanced production line for batteries that drastically outperform those currently on the market. These batteries use dynamic stability, a scientific phenomenon discovered at Harvard, to enable differentiation in the form of the battery and manufacturing of the batteries.

This phenomenon allows the batteries to combine two next-generation technologies: lithium metal and all-solid-state batteries. The breakthrough is particularly significant for electric vehicles (EVs), as it offers a scalable solution to improve battery energy density, charging speed, and safety while maintaining compatibility with existing manufacturing infrastructure.
These batteries are unique in their performance, surpassing current commercial batteries in energy density, charge rate, and safety. Equally important, Adden Energy has developed processes for producing these next-generation batteries on conventional, readily available manufacturing equipment.
“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 commonly used for lithium-ion production, which gives us a clear route to scale-up and manufacturing.”
This pilot line produces Adden Energy’s batteries on equipment standard for the lithium-ion industry. This is a major differentiator for Adden Energy’s technology.
Typical lithium metal solid-state batteries require extremely slow and costly equipment to produce. In turn, this makes batteries too expensive to use in applications like EVs. With only minor modifications to standard equipment, along with Adden Energy’s patented technology, large scale lithium metal solid-state batteries can be produced economically.
Adden Energy has already started receiving purchase orders from automakers and other industrial users buying cells for validation in their applications. Those purchased cells will be produced on this new line.
In late January, Adden Energy hosted a commissioning event for the new line. The Massachusetts Secretary of Economic Development Yvonne Hao, who is also the Chair of MassVentures, joined to tour the new facility and see the batteries in action. MassVentures has supported this technology and team since its inception at Harvard University with a Catalyst grant. Later, MassVentures participated in the company’s Seed round in 2022 and the Series A in 2024 and has maintained a seat on the company’s board since 2022.
The line will reach its full production rate this summer, allowing Adden Energy to meet the rapidly growing demand from its automaker customers across the globe.
