Effects of titanium incorporation on phase and electrochemical performance in LiFePO4 cathode material

► Nominal LiFe1−xTixPO4 cathode materials were synthesized via solid-state reaction. ► A clear feature of Ti-doped LiFePO4 has been clarified. ► The formation of impurity phases strongly depends on Ti doping level. ► Appropriate amount of Ti in LiFePO4 can enhance the electrochemical performance. Ti...
