Triboelectric nanogenerator (TENG) has been considered as a new type of energy harvesting technology, which employs the coupling effects of triboelectrification and electrostatic induction. One key factor having limited its application is the energy storage. In this work, a high performance Li₃V₂(PO₄)₃/C material synthesized by low-cost hydrothermal method followed with subsequent annealing treatment was studied to efficiently store the power generated by a radial-arrayed rotary TENG. Not only does the Li₃V₂(PO₄)₃/C exhibit a discharge capacity of 128 mAh g^–1 at 1 C with excellent cyclic stability (capacity retention is 90% after 1000 cycles at a rate of 5 C) in Li-ion battery, but also shows outstanding energy conversion efficiency (83.4%) compared with the most popular cathodic materials: LiFePO₄ (74.4%), LiCoO₂ (66.1%), and LiMn₂O₄ (73.6%) when it was charged by high frequency and large current electricity directly from by TENG.
