Here, abilities of CNT, CNT-CoO and CNT-TiO 2 as anodes in LIB and NIB are investigated. Results stated that the top carbon atom in CNT is more stable site to attach the CoO and TiO 2 on CNT surface. The ΔG and V cell of Li and Na on CNT and CNT-CoO and CNT-TiO 2 surfaces are calculated. It can be concluded that the V cell and capacity values of LIBs are higher than NIBs. Results indicated that the attached metal oxide/dioxide (CoO and TiO 2 ) to CNT can improve the V cell and capacity of LIB and NIB, efficiently. Finally, results presented that the CNT-TiO 2 is proposed as new anodes material in batteries.
