This application provides a dual-frequency laser frequency difference adjustment system and method based on stress transfer. The system includes a dual-frequency laser and a detection component. The dual-frequency laser includes a housing, a magnetic strip, a first reflector, a second reflector, and a first deformation functional component. The first deformation functional component is connected between the first reflector and the housing and is configured to undergo at least plastic deformation when subjected to external force, and to transmit the stress generated by its deformation to the first reflector. The detection component includes a polarizer, a detector, and a processor. The detector receives the laser light emitted from the dual-frequency laser and passes through the polarizer, and converts the laser light into an electrical signal. The processor receives the electrical signal and generates frequency difference information of the two linearly polarized beams of the laser light. According to this application, damage to the dual-frequency laser can be reduced during frequency difference adjustment, and the frequency difference stability of the dual-frequency laser can be improved, as well as the ease of operation of frequency difference adjustment.

The invention provides an electrolyte and a secondary battery, the electrolyte comprises a solvent, an additive and an electrolyte, the solvent comprises fluoroethylene carbonate, a compound as shown in a formula I and a compound as shown in a formula II, the mass ratio of fluoroethylene carbonate to fluorochain ester is 1: (0.33-4), the mass ratio of the compound as shown in the formula I to the compound as shown in the formula II is 1: (0.33-3), and the additive and the electrolyte are used for preparing the electrolyte. Based on the mass of the electrolyte, the mass percentage A of the fluorinated solvent is more than or equal to 20% and less than or equal to 80%; the additive comprises tetraethylene silane, based on the mass of the electrolyte, the mass percentage of the tetraethylene silane is M, and M is larger than or equal to 0.02% and smaller than or equal to 3%. Through the arrangement, the fluoroethylene carbonate, the compound as shown in the formula I, the compound as shown in the formula II and the tetraethylene silane have a synergistic effect, so that the electrolyte has proper viscosity and relatively high oxidation resistance, and meanwhile, the negative influence of defluorination on a positive electrode can be improved; therefore, the high-temperature cycle performance and the high-temperature storage performance of the secondary battery under the high-pressure condition are improved.
