Hard carbon is the main anode material for sodium-ion batteries, made by carbonizing biomass, resins, pitch, or polymers. A new QY Research report projects the global market will grow from $680 million in 2025 to $2.72 billion by 2032, a compound annual growth rate of 21.8%. That growth hinges on sodium-ion cells finding larger roles in grid storage, backup power, and low-speed EVs. The report breaks the market down by precursor, particle configuration, and reversible capacity. It also names suppliers including Kuraray, Kureha, JFE Chemical, POSCO Future M, BTR, and HiNa Battery. For anyone tracking storage supply chains, the key question is whether hard carbon production can scale fast enough and at low enough cost to make sodium-ion competitive with lithium-ion in stationary storage.
