Transitional Metal Oxides (TMOs) has been considered as one of the promising candidates for anode materials in Lithium-ion batteries (LIBs) due to their high theoretical capacities. However, low electronic conductivity, volume expansion during discharge/charge cycles and poor rate capability challenges its further use in LIBs. In this work, unique behavior of self-revival in the capacity with cycling is presented. Self-revival in the capacity was attained by doping pristine tungsten trioxide (WO 3 ) with nitrogen at high temperature. The percentage increase of self-revived discharge capacity corresponding to the preceding discharge capacity at cycles, 9 th (412.85 Vs 370.95 mAhg -1 ), 13 th (405.24 Vs 390.95 mAhg -1 ) and 36 th (552.38 Vs 138.57 mAhg -1 ) cycles were 11.29%, 3.65% and 298.63%, respectively. This interesting phenomenon of self-capacity revival can be attributed to the reduction in the particle size of WO 3 that leads to high surface area. In addition, the created oxygen vacancies and defects make the reduced WO 3 electrochemically active and enhance the catalytic activity.
