Guoke Tanmei raises hundreds of millions of yuan Pre-A for carbon materials
What's the deal? Guoke Tanmei New Materials, a maker of carbon-based energy storage materials, has closed a Pre-A round worth several hundred million yuan. Investors include Furong Investment, Bozhou Industrial Investment, and Taiyue Capital, with existing backer Changxing Industrial Group adding to its stake.
What's the endgame? The company will spend the money to scale up high-performance porous carbon capacity and build a supercapacitor production line. The goal is a "material-to-device" strategy that moves it from research into manufacturing.
Why now? The round follows a US$13.8M angel-plus raise in February 2026, signalling continued investor support. Guoke Tanmei says its 500-tonne porous carbon line is already in production, with products undergoing validation by major customers.
What could go wrong? Funding alone does not prove commercial scale. The key tests ahead are ramping capacity, converting customer validation into orders, and achieving cost competitiveness.
The signal: Commercialisation signals for sodium-ion batteries are strengthening, raising the stakes for reliable carbon material supply. CATL has announced a major storage supply partnership and is advancing a hard-carbon demonstration line with Shanshan Technology, underscoring why capacity and validation now matter most.
