Application research and prospect of lithium carbon fluoride primary battery in aerospace field

In recent years, with the rapid development of aerospace technology, there is a higher demand for energy. High-performance electrical energy systems can increase payload, reduce launch costs and improve on-orbit reliability. At the same time, with the change of application scenarios, the diversity of energy has also been tested. Lithium carbon fluoride primary battery (Li-CF
x
) has gradually emerged in the fields of aerospace and weaponry recently due to its ultra-high energy density (700-1000Wh/kg), ultra-long wet shelf life (more than 10 years, annual self-discharge rate less than 2%), free ground and on-orbit maintenance, wider storage and working temperature. This paper focuses on the working characteristics, application research and prospect of lithium carbon fluoride primary battery in the aerospace field, and provides a solution for different aerospace energy needs.
