The present invention belongs to the technical field of solid-state lithium batteries, and particularly discloses a hybrid solid-liquid electrolyte lithium battery. The lithium battery includes a positive electrode plate, a negative electrode plate and a composite solid electrolyte sheet arranged between the positive electrode plate and the negative electrode plate, wherein the composite solid electrolyte sheet includes a solid electrolyte core layer and buffer adhesive layers arranged on both sides of the solid electrolyte core layer, wherein the solid electrolyte core layer is mainly formed by mixing a core layer inorganic solid electrolyte, an electrolyte polymer and an electrolyte additive, and the buffer adhesive layer mainly formed by mixing a buffer adhesive layer inorganic solid electrolyte, a buffer adhesive layer lithium salt and a buffer adhesive layer additive. The lithium battery of the present invention is prepared by combining coextrusion technology and rolling technology to achieve one-time processing and forming, which has the characteristics of a high production efficiency, and a simple operation, and the obtained lithium battery has relatively higher electric cycle performance and safety performance.

A propulsion control device of a 3D printing-based tunnel boring machine, includes two propulsion control modules, and each of which includes tunnel support assemblies, a propulsion control assembly and a barrel body, where a propulsion sliding sleeve is arranged on an outer surface, and several tunnel support assemblies are arranged on an outer side of each propulsion sliding sleeve. Support plates on the two propulsion control modules alternately rise to support a 3D printed tunnel pipe. In the propulsion control module with the support plates in a closed state, a propulsion hydraulic cylinder controls a propulsion hydraulic cylinder extending end to contract, so as to pull the propulsion sliding sleeve to a front section of the barrel body; and in the propulsion control module with the support plates in a support state, the barrel body continuously advances relative to the propulsion sliding sleeve.
