Sunrise New Energy receives approval for two patents for Na-ion anode materials

China-based Sunrise New Energy Co., Ltd. announced that its subsidiary, Sunrise (Guizhou) New Energy Materials Co., Ltd., has received preliminary approval from the National Intellectual Property Office for two separate patents related to anode mateeials for,sodium-ion batteries.

Sodium-ion batteries predominantly utilize hard carbon materials as the anode material. However, these materials suffer from several noticeable drawbacks, including low specific capacity, low compactness, and limited expansion. Moreover, the inherent disparity in electronic conductivity of the material leads to performance variations in terms of rate capability.

Sunrise is a research-driven high-tech enterprise with cutting-edge technology in the field of anode materials worldwide, placing us in a leading position within the industry. We have filed domestic and international patents related to new graphite, silicon-carbon, and hard carbon technologies.

Due to our technological leadership, we have been able to secure top-tier domestic and international clients such as CATL, BYD, Narada Power, and Hithium Energy, specializing in electric vehicle and energy storage batteries. Furthermore, we have contributed significantly as a principal drafting entity to the national battery industry standard policy, “Technical Specifications for the Production Process of Artificial Graphite Anode Materials”.

Advanced sodium batteries may soon outclass lithium batteries due to cost alone.


A typical EV battery has about 8 kilograms of lithium
At $14.00 per pound for lithium this is less than $300 per car.


Why does it have to be Lithium vs Sodium? Why not a combination of Sodium and Lithium? Even Thomas Edison added Lithium Hydroxide to the Nickel-Iron Battery.

it’s possible and may provide the best solution. These batteries have what is called “Sodium and lithium incorporated cathodes”.
