US backs consortium to scale battery production with abundant materials
The US Department of Energy is backing BattMan, a consortium led by national laboratories to move advanced battery technologies from research into domestic manufacturing. It aims to address the gap between promising laboratory results and commercial production, which matters as demand grows for batteries in electricity grids, data centres and electric vehicles.
The programme brings together four national laboratories, five universities and manufacturers, and will use AI, sensors and automated pilot lines to monitor and adjust production. Oak Ridge National Laboratory plans to test wet and dry electrode manufacturing at its Battery Manufacturing Facility. BattMan also aims to reduce costs, improve safety and performance, and develop batteries using more abundant, domestically sourced materials to ease reliance on critical minerals.
In short
- BattMan aims to scale new battery technologies in the US.
- AI and automated lines will help monitor manufacturing.
- The consortium is seeking more partners and abundant materials.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Federal backing for BattMan could help bridge the costly gap between laboratory research and commercial production, strengthening US manufacturing capacity as demand for batteries grows. Shared pilot lines, sensors and AI may help identify efficient production methods, while developing batteries from more abundant domestic materials could reduce supply-chain vulnerabilities and reliance on critical minerals.
The case against
Government support for a particular consortium risks directing public money towards technologies or production methods that may not prove commercially viable, when private firms might be better placed to judge demand and invest. The programme’s benefits are uncertain: scaling laboratory results is difficult, and domestic sourcing or new manufacturing processes may not deliver lower costs or less reliance on critical minerals in practice.
Explained simply
Batteries store electricity for later use and power devices ranging from electric cars to large grid systems. Some newer battery designs use materials that are more widely available than the minerals used in many batteries today, but promising results in a lab do not automatically translate into reliable, affordable products made at scale.
The US Department of Energy funds research and development in energy technology, including work at national laboratories. BattMan brings together four of these laboratories, universities and manufacturers to test ways of producing batteries, with Oak Ridge National Laboratory examining different methods for making electrodes, a key part of a battery.
The work matters because demand for batteries is growing, including from electricity grids, data centres and electric vehicles. Making more batteries with domestically sourced materials could reduce reliance on minerals that are harder to obtain, while production methods that improve cost, safety or performance could help new designs reach wider use.
