Here is a fact about lithium-ion batteries that almost never makes it into a keynote: the single most expensive component of a battery cell is a powder. The cathode - the positive electrode, the part that stores and releases lithium ions - is routinely the largest line item in a cell's bill of materials, often cited at somewhere close to half. Everybody wants a cheaper electric car and a cheaper grid battery. Very few people want to talk about the powder. ACT-ion Battery Technologies wants to talk about the powder.
ACT-ion is a Dallas company, headquartered in a downtown high-rise on Ross Avenue, with a team of roughly twelve people. It was spun out of Hunt Energy Enterprises in 2019 and it is run by Jin-Myoung Lim, who carries the somewhat heroic title of co-founder, CEO, and CTO - which is startup shorthand for "he invented the thing and now he also has to sell it." The thing, in this case, is cathode active material, or CAM, and the pitch is not that ACT-ion has discovered a new battery chemistry. The pitch is that it has found a better way to make the chemistry everyone already uses.
The unsexy breakthrough
This is a subtle but important distinction, and it is worth dwelling on because it is the whole company. Most battery startups sell you a molecule: a novel anode, an exotic electrolyte, a solid-state dream that is always about five years away. ACT-ion is selling a process. Conventional cathode production is a batch affair - slow, energy-hungry, thirsty for water, and prone to producing byproducts you then have to deal with. ACT-ion's process is continuous rather than batch, which is the industrial equivalent of switching from baking one loaf at a time to running a bakery that never stops. The company says it produces surface-engineered single crystal cathode powders in a fraction of the time of incumbents, using less energy, less water, a smaller physical footprint, and - the part that makes the CFO look up - at lower cost.
The single-crystal detail matters to battery engineers. Most cathodes are "polycrystalline," clumps of many little crystals that, over hundreds of charge cycles, tend to crack along their grain boundaries. That cracking is one of the quiet reasons your battery gets worse over time. Single-crystal cathodes are more like one solid piece; they resist that fatigue, which translates to longer cycle life and better safety. Making them well and cheaply has historically been the hard part. ACT-ion's claim is that it has made the hard part routine.
The chemistry-agnostic bet
There is a strategic elegance to ACT-ion's second big claim, which is that its process is "chemistry-agnostic." The battery world cannot decide what it wants. For years the answer was NMC - nickel, manganese, cobalt - the high-energy-density chemistry that powers most premium EVs. Then lithium iron phosphate, LFP, staged a comeback because it is cheap, safe, and uses no cobalt. Now lithium-manganese-rich chemistries are the interesting frontier. A cathode plant tuned for one of these is an expensive thing to retool for another. ACT-ion says the same line can run all of them.
Read cynically, "chemistry-agnostic" is the kind of phrase startups deploy to avoid picking a lane. Read charitably - and the more persuasive read here is the charitable one - it is a hedge against a market that genuinely does not know its own mind. If you cannot predict which chemistry wins, the valuable position is the one that wins regardless. ACT-ion is trying to be the toll road, not the car.
The money, and who wrote the checks
In February 2025, ACT-ion closed a $7.5 million round - labeled Pre-Series A, filed in places as a seed - led by BASF Venture Capital. That name is the tell. BASF is one of the largest cathode material producers on the planet; when its venture arm funds a company whose entire premise is a cheaper way to make cathodes, it is either hedging its own franchise or scouting the future, and possibly both. Joining were Hunt Energy Enterprises (the former parent, still believing), Mirae Asset Capital, Arosa Capital Management, and LG Technology Ventures - LG being, not coincidentally, one of the world's great battery makers. In September 2025 the company added roughly $4 million more, co-led by KB Investment and Kyobo Securities, bringing the total to about $11.5 million.
That is not a huge number by the standards of hard-tech energy startups, which is itself interesting. ACT-ion has attracted strategic global investors - German chemicals, Korean batteries, Korean finance - without raising a fortune. The signal from a syndicate like that is worth more than the dollars in it. These are the people who would know if the powder were bunk.
From lab notebook to loading dock
In September 2025, ACT-ion signed a lease at 1200 Tappan Circle in Carrollton, a suburb north of Dallas, for a pilot plant dedicated to scaling the process. A pilot plant is a company's most honest moment. The lab is where a process looks brilliant on a good day; the pilot plant is where it has to work every day, on schedule, at volume. The U.S. Department of Energy has been paying attention - both its Advanced Materials & Manufacturing Technologies Office and its Vehicle Technologies Office have supported the scale-up - because a domestic battery supply chain is a stated national goal, and you cannot have one without domestic cathode powder. Carrollton's mayor, Steve Babick, welcomed the company as a clean-energy addition to the local economy.
ACT-ion had already collected an R&D 100 Award in 2024, the industry's version of an Oscar for the kind of invention no consumer will ever see. It is a good omen. R&D 100 winners tend to be companies quietly making an industrial input meaningfully better while nobody live-tweets it.
What ACT-ion can actually do, if it works at scale, is lower the floor under every battery that uses its cathodes - which is to say, make EVs and grid storage a little cheaper, a little safer, and a lot more American. The company will have to prove that the numbers that hold in a lab hold on a loading dock. That is the entire remaining question, and it is a big one. But it is the right question, aimed at the right, expensive, overlooked powder.
