• The electrochemical performance of CuF 2 was studied for FSBs. • The influence of conductive additives on the CuF 2 performance was investigated. • Both SWCNT and AB were simultaneously incorporated into the CuF 2 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. In this paper, the influence of conductive additives such as single-wall carbon nanotubes (SWCNTs) and acetylene black (AB) on the electrochemical performance of CuF 2 based electrodes in fluoride shuttle batteries are studied. CuF 2 based-electrodes with different SWCNT and AB concentrations, namely, CuF 2 /AB 4.5 /SWCNT 1.7 (85.4/4.5/1.7/8.4 in wt%) and CuF 2 /AB 3.8 /SWCNT 3.8 (73.4/3.8/3.8/19 in wt%), are prepared. Scanning electron and laser microscopy analyses show that the strong van der Waals (VdW) attractions in SWCNTs are reduced when an appropriate ratio between SWCNTs and AB is attained. This aids in the possible reduction of phase separation and aggregation of CuF 2 -based composite films. It is noticed that the contribution of AB in reducing the aggregation of CuF 2 is significantly high as it spreads the entire surface and acts as a bridge between SWCNTs and CuF 2 . Further, the electrochemical performance test results have revealed significant improvement in the capacity of CuF 2 at high C rates when appropriate concentrations of SWCNTs and AB are used. In addition, the recovery of the capacity at all C rates is also improved. The results show that the simultaneous inclusion of both AB and SWCNTs play a critical role to improve the performance of CuF 2 -based FSBs.
