The present invention relates to a lithium secondary battery and a method for manufacturing a lithium secondary battery, in which the lithium secondary battery comprises: a positive electrode comprising a positive electrode current collector and a positive electrode active material layer provided on the positive electrode current collector; a negative electrode including a negative electrode current collector, a negative electrode active material layer provided on the negative electrode current collector, and a solid electrolyte layer provided on the negative electrode active material layer; a separator disposed between the positive electrode and the negative electrode; and an electrolyte, wherein the A value in the following mathematical formula 1 may be 10% or more. [mathematical formula 1] A = {(F + C) / (F + C + G + M + E)} * 100F and C are respectively a fluorine-containing group content (unit: [mu] g / cm < 2 >) and a carbonate group content (unit: [mu] g / cm < 2 >), which are determined by capillary electrophoresis (CE) analysis of the solid electrolyte layer, and G, M, and E are respectively an ethylene glycol group content (unit: [mu] g / cm < 2 >), a methyl group content (unit: [mu] g / cm < 2 >), and an ethyl group content (unit: [mu] g / cm < 2 >), which are determined by capillary electrophoresis (CE) analysis of the solid electrolyte layer. This is determined by Nuclear Magnetic Resonance (NMR) spectroscopic analysis of the solid electrolyte layer.

The present disclosure relates to the field of material sorting, in particular to a switch assembly and a sorting machine, wherein the switch assembly comprises: a micro switch arranged on a fixed plate, the micro switch comprising a mechanical probe capable of being extended and retracted, the mechanical probe being capable of triggering a corresponding signal in the extended state and / or the retracted state; a handle rotatably arranged on a door plate, wherein the door plate is movable relative to the fixed plate; a trigger fixedly arranged on the handle and capable of rotating synchronously with the handle, the trigger forming an abutting arc surface; wherein the handle is rotated to a first position, the abutting arc surface pushes the mechanical probe to the retracted state; the handle is rotated to a second position, the abutting arc surface leaves the mechanical probe to extend the mechanical probe to the extended state. The switch assembly independently forms a chain of the micro switch, the handle and the trigger, and effectively associates the micro switch, the handle and the trigger. The safety and use experience of the whole device are improved, and the reliability and stability of the device are improved.
