Electrochemical performance investigation. (a–c) GCD cycling performance comparisons among SnO2[O]rTiO2-PGN with single/binary/ternary phase samples under 100 mA g−1. (d) CD profiles of SnO2[O]rTiO2-PGN, Ad-SnO2-G, Ana-SnO2-PGN, and Ana. TiO2 at a current density of 10 mA g−1. (e) CV pattern under different cycles at 0.1 mV s−1 reveals the electrochemical processes in the first five cycles. (f) Charging capacity profiles under 10–200 mA g−1. (g) continuing cycling test of the SnO2[O]rTiO2-PGN LIB anode at a current density of 100 mA g−1.
