- In this study, it is aimed to develop $LiMn_2O_4$/MWCNT nanocomposite cathode materials by using different calcination temperatures (300, 500, 700°C). The aim of using MWCNTs in the active material is to overcome poor conductivity and to increase stability of the electrodes during charging and discharging. The nanocomposites were produced by sol-gel method, which allows producing very fine particle size of $LiMn_2O_4$. $LiMn_2O_4$ and $LiMn_2O_4$/MWCNT were uniformly coated on an Al-foil to obtain 500 μm thicknesses with a specific amount of binder and conducting agent. The surfaces of cathodes were coated with ZnO by using magnetron sputtering PVD with a thickness of 10 nm. Coin-type (CR2016) test cells were assembled, directly using the $LiMn_2O_4$/MWCNTs and surface coated $LiMn_2O_4$/MWCNTs as anode and a lithium metal foil as the counter electrode.
