Zhejiang Zhiyuan Nake Energy Technology Co., Ltd.

About

Zhejiang Zhiyuan Nako Energy Technology Co., Ltd., abbreviated as Zhiyuan Nako, is located in the Binhai New Area Science and Innovation Park, Shaoxing City, Zhejiang Province. It is one of the earliest international technical teams to conduct research on anode self-generating batteries. The core R&D team, built on top-tier talent, brings together senior electrochemistry scholars from prestigious universities such as Shanghai Jiao Tong University and Zhejiang University, as well as experienced engineers from leading international sodium-ion and lithium-ion battery companies. The team has been deeply engaged in the research and development of anode self-generating battery technology for over a decade. In 2026, Zhiyuan Nako received strategic investment from battery giant Chaowei Group, which also serves as a core customer. This forms a deep integration of capital support and industrial implementation with Zhiyuan Nako, providing the new energy industry with a low-cost, low-temperature resistant, high-temperature resistant, high-safety, and high-performance anode-free sodium battery solution. Zhiyuan Nako breaks through the limitations of traditional battery structures. Through anode self-generating technology, it eliminates the anode active material in conventional sodium-ion batteries. By precisely controlling the deposition process of metal elements, a uniform and dense metal layer is directly formed on the current collector as the anode, achieving a 40% increase in energy density and a 40% reduction in manufacturing cost, while combining high safety with a wide temperature range performance. Low-temperature resistance: Breaks through the low-temperature performance bottleneck, completely solving winter range anxiety. Capacity retention >92% at -20°C, >90% at -30°C. High-temperature resistance: Effectively suppresses high-temperature side reactions, ensuring all-weather travel safety. The battery operates stably and reliably in extreme hot environments of 50~60°C. High performance: Supports fast charging and high-power output, perfectly meeting the instantaneous power requirements of power batteries. 2C charging retention >99%, 3C charging retention >99%. Additionally, the battery has inherently high safety, as solid as a rock. It completely eliminates the risk of anode combustible materials. It passes extreme tests such as nail penetration, internal short circuit, and hot box testing without smoking, catching fire, or exploding.
