Adden Energy Launches R&D Pilot Line to Advance Dynamically-Stable Battery Scaling
Adden Energy, a cutting-edge battery technology company, has officially commissioned a state-of-the-art production line designed to manufacture next-generation batteries that significantly outperform current commercial options. These revolutionary batteries leverage a breakthrough scientific phenomenon known as dynamic stability, originally discovered at Harvard University, to achieve substantial advancements in both battery architecture and manufacturing processes.
The implementation of dynamic stability enables Adden Energy’s batteries to integrate two transformative technologies: lithium metal batteries and all-solid-state batteries. This unique combination allows the company to produce batteries with remarkable improvements in energy density, charging speed, and safety. Furthermore, Adden Energy has successfully developed manufacturing techniques that allow these high-performance batteries to be produced using conventional, readily available production equipment—eliminating a major bottleneck that has hindered the commercialization of other advanced battery technologies.
A Breakthrough in Battery Performance and Manufacturing
The introduction of dynamic stability represents a fundamental shift in battery science. Traditionally, lithium metal batteries and all-solid-state batteries have been viewed as promising yet difficult to commercialize due to challenges related to cost, scalability, and reliability. By overcoming these barriers, Adden Energy is positioned to make these high-performance batteries widely accessible for a variety of industries, including electric vehicles (EVs), consumer electronics, and grid storage applications.
“Our initial prototypes had already demonstrated a 50% improvement in energy density compared to conventional lithium-ion batteries,” said Dr. Pu Zhang, Chief Product Officer at Adden Energy. “These prototypes also offered the added advantages of charging in under 10 minutes and being non-flammable. Now, with the commissioning of this new production line, we’ve proven that these groundbreaking batteries can be manufactured using the same equipment currently employed for lithium-ion production. This provides us with a clear pathway to large-scale manufacturing and market adoption.”
For years, the battery industry has faced a dilemma: while lithium metal solid-state batteries theoretically offer substantial benefits over lithium-ion batteries, they have remained impractical due to high production costs and the need for specialized, slow, and expensive manufacturing equipment. Adden Energy’s breakthrough lies in the ability to adapt standard lithium-ion production lines with only minor modifications, dramatically reducing the costs associated with scaling up these next-generation batteries.
Meeting Market Demand and Scaling for the Future
As the global demand for more efficient and safer energy storage solutions continues to grow, Adden Energy has already begun receiving purchase orders from major automakers and industrial customers looking to validate its battery cells for real-world applications. The newly commissioned pilot line will fulfill these initial orders, allowing customers to evaluate the technology in their specific use cases.
On January 28th, Adden Energy hosted a commissioning event to celebrate the launch of the new production line. Massachusetts Secretary of Economic Development Yvonne Hao, who also serves as Chair of MassVentures, attended the event to tour the facility and witness the innovative battery production process firsthand. MassVentures has played a pivotal role in supporting Adden Energy since its early days as a Harvard University research project. The organization provided initial funding through a Catalyst grant and later participated in the company’s Seed round in 2022 and Series A funding round in 2024. Since 2022, MassVentures has maintained a seat on Adden Energy’s board, underscoring its commitment to fostering high-tech innovation in Massachusetts.
“Adden Energy’s story is a perfect example of the entrepreneurial excellence we have in Massachusetts,” said Hao. “The company is a Harvard spin-out that is commercializing breakthrough energy science, building domestic manufacturing capabilities, and creating high-tech jobs right here in the Commonwealth.”
The pilot line is expected to reach its full production rate by this summer, enabling Adden Energy to meet the rapidly increasing demand from its automaker customers and other industry partners worldwide. As more companies seek advanced battery solutions to power the next generation of electric vehicles and energy storage systems, Adden Energy’s scalable and cost-effective approach could play a transformative role in accelerating the global transition to clean energy.
Addressing Key Industry Challenges
One of the most pressing challenges in the battery industry today is the need for higher energy density without compromising safety or affordability. Conventional lithium-ion batteries have reached their practical limits in terms of energy storage capacity, meaning that further performance improvements require fundamental changes in battery chemistry and design.
Lithium metal batteries offer a promising alternative because they can store significantly more energy than traditional lithium-ion batteries. However, they have historically faced stability and safety issues, including the formation of dendrites—tiny, needle-like structures that can grow within the battery and cause short circuits or fires. Adden Energy’s dynamic-stability approach addresses this challenge by preventing dendrite formation, making lithium metal batteries safer and more reliable than ever before.
Another major hurdle for all-solid-state batteries has been their prohibitively high manufacturing costs. Most all-solid-state battery designs require custom-built production lines, which significantly increases capital expenditures and slows down adoption. Adden Energy’s ability to manufacture its batteries on standard lithium-ion production equipment represents a major competitive advantage, allowing for seamless integration into existing supply chains without the need for costly infrastructure overhauls.
Scaling Up for Mass Adoption
As the global EV market continues to expand, the demand for batteries with higher energy density and faster charging capabilities is at an all-time high. Automakers are actively searching for battery technologies that can extend vehicle range, reduce charging times, and improve overall safety—all while keeping production costs competitive. Adden Energy’s dynamically stable lithium metal solid-state batteries check all these boxes, making them a highly attractive option for next-generation EVs.
In addition to the automotive sector, these batteries have significant potential in other applications such as consumer electronics and grid storage. The ability to store more energy in a smaller and lighter package could enable slimmer, longer-lasting smartphones, laptops, and wearable devices. Meanwhile, grid storage applications could benefit from safer, longer-lasting batteries that enhance the reliability of renewable energy sources like solar and wind power.
As Adden Energy moves forward, the company remains focused on refining its technology, expanding its production capabilities, and forging partnerships with key industry players. By proving that dynamically stable lithium metal solid-state batteries can be produced at scale using existing manufacturing infrastructure, Adden Energy is paving the way for a future where high-performance, cost-effective batteries become the norm rather than the exception.
With the pilot line now operational and full-scale production on the horizon, Adden Energy is well-positioned to lead the next era of battery innovation, delivering solutions that will power the world’s transition to cleaner, more efficient energy systems.
