Lithium fluorocarbon batteries have gained widespread application in areas such as implantable medical devices, military application, sensors, wireless devices, and aerospace due to their high energy density, excellent safety performance, and low self-discharge rates. The performance of lithium fluorocarbon batteries is particularly critical in extending the service life of leadless pacemakers. This article reviews the strategies for enhancing the capacity and voltage of lithium fluorocarbon batteries. The following three aspects are mainly discussed:firstly, the advancement of high specific capacity and high voltage fluorocarbon, involving the optimization of carbon source structure, pre- and post-fluorination treatment, and control of fluorination methods; secondly, the development of high-performance electrolytes, including the use of low concentration lithium salts with solvents processing high donor number, as well as reactive lithium salts and solvents; lastly, the optimization of battery manufacturing processes, particularly focusing on thick electrode and electrolyte injection processes. A comprehensive analysis indicates that by meticulously modulating the structure of carbon sources, optimizing the proportion of fluorocarbon bonds, improving electrolyte formulations, and innovating process technologies, it is possible to develop lithium fluorocarbon batteries with higher capacity and voltage, thereby effectively enhancing the service life of leadless pacemakers.
