For too long, America has been sleepwalking into a dangerous dependency on Chinese battery technology. It’s not just about electric vehicles or smartphones anymore. It’s about national security, economic resilience, and the ability to stand firm in the face of geopolitical tension. And make no mistake: the stakes are high.
Chinese-made batteries, particularly those embedded with sensitive components, pose a dual threat. First, they can serve as conduits for data collection, quietly siphoning information from American infrastructure. Second, in the event of a conflict, such as over Taiwan, China could simply flip the switch and cut off battery supplies, crippling everything from our energy grid to our defense systems.

A quiet revolution is underway in battery chemistry. Lithium Iron Phosphate (LFP) batteries are rapidly overtaking their Nickel Manganese Cobalt (NMC) counterparts. They’re up to 50 percent less expensive. They last longer, and because of their lower energy density, they’re less prone to the fiery meltdowns that have plagued NMC designs.
More importantly, the materials needed for LFP batteries—lithium, graphite, iron, and phosphate—can be sourced right here in the United States. Lithium from North Carolina, Nevada, and Arkansas. Iron from Minnesota and North Dakota. Phosphate from Florida and Louisiana. No need to rely on cobalt from the Congo or nickel from Indonesia and Russia. No need to play supply chain roulette with autocratic regimes.
LFP batteries aren’t just for cars. They power data centers, grid-scale energy storage, EV charging stations, and homes. They’re also vital for defense applications, from aerial drones to underwater vehicles. Yet despite the construction of multiple LFP gigafactories by Tesla, Ford, GM, LG, and Samsung, one critical piece remains missing: the cathode active material (CAM). It’s still made in China.
Enter Sparkz, an American startup with a solution. Sparkz has developed a domestic technology to produce CAM for LFP batteries at scale, with performance and cost parity to Chinese products. A Sacramento plant is already in production. Now, Sparkz is preparing to scale up to a 44,000-ton capacity by 2029, with a main plant in Oklahoma, and other satellite plants throughout the United States.
