- ➤Mid-sulfur material achieved 94.8% graphitization versus 93.9% for low-sulfur material
Expert Statements
Haiping Hu, Founder, CEO and Chairman of E-Power Inc.
“We chose the mid-sulfur coke route deliberately, and GSD-2 has been in commercial supply for more than three years, so that choice has been tested in production and not only in the laboratory.”
Haiping Hu, Founder, CEO and Chairman of E-Power Inc.
“We are setting out the technical basis because shareholders should be able to see what sits behind the product.”
DOVER, USA, Oct. 23, 2026 (GLOBE NEWSWIRE) -- E-Power Inc. (“E-Power,” the “Company,” “we” or “our”) (NASDAQ: EPOW), a provider of advanced battery materials and AI Data Center (AIDC) microgrid solutions, today disclosed technical details of the mid-sulfur petroleum coke raw-material route used by its joint venture, Sunrise (Guizhou) New Energy Materials Co., Ltd. (“Sunrise Guizhou”), in its graphite anode materials for energy storage systems (“ESS”).
In side-by-side evaluation at comparable median particle size (Dv50 of approximately 11 μm), graphite anode material produced from mid-sulfur petroleum coke measured a specific capacity of 357.8 mAh/g, compared with 346.8 mAh/g for material produced from conventional low-sulfur coke — approximately 3.2% higher. Graphitization degree measured 94.8% and 93.9%, respectively.
