Zusammenfassung:The invention provides a silicon-based negative plate as well as a preparation method and application thereof, and relates to the technical field of lithium ion batteries. Specifically, the solar cell comprises a current collector layer, an electrolyte layer and a silicon-based layer which are connected in sequence, wherein the electrolyte layer comprises an ion conducting agent and a lithium salt, and the electrolyte layer is composed of a plurality of filaments. According to the silicon-based negative plate disclosed by the invention, on the premise of ensuring high gram capacity of the electrode plate, volume expansion of silicon particles can be inhibited, the electrode plate is prevented from falling off, and the cycle performance of the electrode plate is improved. When the silicon-based negative plate is used for preparing a battery with an all-solid-state structure, the gram volume of the negative plate and the cycling stability of the battery can be effectively improved, the energy density of a sulfi
