Our group has established a growth strategy in July 2025, positioning "aggressive development of new businesses" and "proactive promotion of various alliances (business and capital partnerships)" as core policies, aiming to maximize corporate value and contribute to a sustainable society.

Great Power Nexcell is a Japanese group company of Great Power Energy & Technology Co., Ltd. (Guangzhou Great Power Energy & Technology Co., Ltd., stock code: SHE 300438), a globally recognized leading manufacturer of lithium-ion batteries and energy storage systems (ESS) listed on the Shenzhen Stock Exchange (SZSE).

Through this alliance, our company will leverage the Great Power Group’s globally renowned cutting-edge battery technology, mass production synergies, and robust supply chain infrastructure to participate in and invest in Great Power Nexcell’s domestic data center and energy storage projects. This initiative will not only stabilize infrastructure and contribute to local communities but also establish new revenue foundations for our company, strongly advancing long-term corporate value enhancement.
