Influence of conductive additives on the electrochemical compatibility of cupper fluoride cathode for FSB

•The electrochemical performance of CuF2 was studied for FSBs.•The influence of conductive additives on the CuF2 performance was investigated.•Both SWCNT and AB were simultaneously incorporated into the CuF2 electrode.•The addition of appropriate amount of AB provides a homogeneous distribution.•The inclusion of SWCNTs decreases the capacity fading during the cycling.•The combined effect of SWCNT and AB has a significant impact on battery performance.
