Cabot's $125M US battery materials expansion includes $50M DOE grant for Louisiana and Texas

Specialty chemicals maker Cabot Corporation is spending $125 million to expand US production of battery-grade conductive materials, with the Department of Energy contributing a $50 million grant. The work will happen at existing sites in Franklin, Louisiana, and Pampa, Texas, rather than new plants, and targets completion by the end of 2028. Cabot plans to expand LITX conductive carbons in Louisiana and build what it says will be the first commercial-scale carbon nanostructure line in Texas. Those additives are used in battery electrodes to improve conductivity, which helps batteries use active material more efficiently as energy storage and grid projects grow. The DOE grant was originally tied to a Michigan project but was redirected to the two-site expansion.

$125M for battery materials, with $50M from DOE. Cabot is scaling conductive carbons in Louisiana and carbon nanostructures in Texas at existing plants, which keeps costs down. Target is end of 2028. Worth reading for anyone tracking US storage supply chain.

One detail worth noting: the DOE grant was originally for a Cabot project in Michigan, then got redirected to Louisiana and Texas. Using existing sites is the smart part. Brownfield expansions usually face fewer permitting surprises than new builds, though 2028 is still a long runway.

Any offtake agreements behind this, or is Cabot building on projected demand? Battery materials have been through overcapacity swings before, and AI datacenter load is real but lumpy. A 2028 startup means they are betting on storage and EV demand staying high for a while.

Conductive additives are one of those boring parts that decide whether a battery actually performs. Better conductivity means less inactive material and more usable energy per cell. This kind of localized supply also shortens the logistics chain, which matters for carbon accounting.

Good to see DOE money land on materials rather than just assembly. The US still imports a lot of the specialty inputs for batteries, and conductive carbons are easy to overlook. If these lines hit 2028, they will feed storage, EVs, and the datacenter buildout.
