Li/fluorinated carbon (Li/CF) batteries are promising systems with ultrahigh energy density and long storage life. They are particularly suitable for emerging applications in military equipment, interventional medical devices, and spacecrafts. Research on Li/CF batteries is at a critical point, transitioning from small- to large-scale applications.
For almost half a century, lithium/carbon fluorides (Li/CF x) batteries have been considered irreversible in liquid electrolyte, but they still have attractive features such as a flat discharge plateau, a wide operating temperature window, and outstanding shelf life. Such benefits have spurred interest in developing rechargeable CF x batteries.
Research progresses of carbon fluorides secondary batteries are summarized. The reversibility mechanisms of carbon fluorides batteries are analyzed. The design rules for rechargeable metal carbon fluorides batteries are proposed.
A CFx battery is a lithium carbon monofluoride battery (Li/CFx). Li/CFx batteries are primary or non-rechargeable batteries. Li/CFx batteries have high energy density and long-storage life. They are very stable and ideal for military and space applications. EaglePicher is a leader in the development of lithium carbon batteries and cfx batteries.
