文摘Titanium niobium oxide as an electrode material for lithium-ion batteries(LIBs)has relatively high working potential and theoretical capacity,which is expected to replace a graphite anode.However,it possesses low electronic conductivity,leading to the internal electrochemical polarization of the battery during high current charging,which is mainly reflected in the large difference between the actual electrode capacity and the theoretical capacity.
