Sunrise New Energy Wins Japanese Patent, Expands IP

Sunrise New Energy said a subsidiary was granted a Japanese patent (No. 7413482) for a manufacturing method of graphite‑based anode materials for lithium‑ion batteries, adding to the company’s existing U.S. and Korean patents. The company said the patented process — and a related U.S. patent it also holds — improve efficiency, cycle life and power performance, and the patent news coincided with a roughly 178% post‑market stock surge. Sunrise highlighted applications across EVs, grid storage and AI data center battery packs as it scales production through a completed joint‑venture manufacturing facility and a Guizhou plant powered by renewable energy. The firm previously received a grant from the Guizhou Provincial Department of Science and Technology to establish an innovation workstation focused on next‑generation anode technologies. Despite strong revenue growth, Sunrise continues to face financial challenges, including negative profitability margins and a weak financial strength score. CEO Haiping Hu said the Japanese patent is a significant step in consolidating Sunrise’s international technology footprint to support the EV transition and rising demand for AI data center energy storage.
