Abstract: The present invention discloses a method for recycling a spent lithium-ion battery, including the following steps: sandwiching a cathode of the spent lithium-ion battery with a conductive acid-resistant material as a cathode of a primary battery system; sandwiching an anode of the spent lithium-ion battery with a conductive acid-resistant material as an anode of the primary battery system; injecting an acid solution into a chamber of the primary battery system; and carrying out, after an electrochemical reaction is completed, solid-liquid separation on a mixed liquor in the chamber. The present invention further discloses an electrochemical system for recycling a spent lithium-ion battery. The method for recycling a spent lithium-ion battery in the present invention requires only dismantlement of cathode and anode materials, without a series of complex pretreatment operations on the cathode materials of the spent lithium-ion battery. In addition, by the method, the cathodes and anodes of the spent lithium-ion battery can be recycled at the same time, and valuable elements can be separated, which is greatly improved compared with the electrolytic leaching method. Moreover, there is no need to add an external power supply, which saves energy and can also output electricity.

Abstract: The disclosure provides a precursor solution, a perovskite solar cell and a preparation method thereof. The solute of the precursor solution includes a metal halide, the solvent of the precursor solution is an organic solvent, and the precursor solution contains nanobubbles, which have a diameter not more than 1000 nm, and the zeta potential of the precursor solution does not exceed-20 mV. The method of preparing the precursor solution includes: (1) preparing an organic solvent containing nanobubbles; (2) dissolving a solute in the organic solvent containing nanobubbles. The precursor solution of the disclosure has a very low zeta potential, and the nanobubbles can exist stably in the organic solvent(s) for up to one month. When comparing with traditional methods for preparing the precursor solution of the perovskite cells, the method for preparing the precursor solution of the disclosure can effectively improve the stability, reproducibility and solubility of the metal halide in the organic solvent(s).
