Abstract:
In order to satisfy the increasing requirements on operation time of wearable and portable electronic devices, novel self-powered systems by integrating triboelectric nanogenerator (TENG) with an energy storage device have emerged as a promising technology to provide sustainable power. Here, a flexible sodium composite anode (Na@CC) was prepared by infusing the molten sodium into flexible sodiophilic carbon cloth. The symmetric cell with the Na@CC anode shows stable sodium plating and stripping for 400 h. The full cell with a flexible quasi-solid-state electrolyte, Na3V2(PO4)3@C nanofiber cathode, and Na@CC anode delivers an excellent rate capacity of 72.5 mAh g-1 at 5 C and also exhibits stable cycling performance under different bent degrees. By combining with TENG to form a self-powered system, the flexible quasi-solid-state sodium battery can effectively store the pulse current and shows stable discharging capacity for over 100 cycles. The advanced flexible battery demonstrates its capability as a promising energy storage part in combination with TENGs and shows great potential in powerful flexible self-powered systems.

Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
