Özet

Highlights Li2ZnTi3O8 (LZTO) and MWCNTs modified Li2ZnTi3O8 (LZTO@MWCNTs) were synthesized with the use of fast and economical ball mill assisted solid state method. The CV experiments demonstrate that LZTO@MWCNTs electrode has a higher redox peak intensitiy and electrochemical reversibility compared to the LZTO electrode. DLi+ of LZTO@MWCNT and LZTO electrode was calculated as 2.43 × 10−12 cm2s−1 and 6.79 × 10−13 cm2s−1, respectively. The CV and charge-discharge measurements show that the LZTO@MWCNTs electrode has a smaller polarization compared to the LZTO electrode. The EIS results demostrate that the charge transfer and SEI resistance of LZTO anode can be suppressed via MWCNTs modification.
