High-Temperature Battery Technology: Ensuring Safety and Efficiency

Sunpower New Energy’s 21700 li ion battery incorporates advanced high-temperature battery technology to ensure both safety and efficiency. Our company is committed to pushing the boundaries of battery technology, resulting in cutting-edge solutions for our clients.

One key aspect of our high-temperature battery technology is the doping of metal elements in the anode material. This process improves the crystal structure stability of the lithium cobalt oxide at high temperatures, reducing the oxidation capacity of the material. As a result, our battery exhibits enhanced stability and reliability, even in extreme temperature conditions.

Furthermore, the doping process inhibits the reaction between the electrode material and the electrolyte, further enhancing the safety of our battery. This reduces the risk of thermal runaway and other safety concerns associated with high-temperature operation.

It’s worth noting that our 21700 li ion battery has undergone rigorous testing and certification.
