Embodiment Construction

[0024] Below in conjunction with specific embodiment and accompanying drawing, the present invention is further elaborated and illustrated:

[0025] A method for preparing a lithium battery pole piece, comprising the following steps:

[0026] The first step is to form a semi-finished product with a metal coating on the surface of the metal substrate by physical vapor deposition in a negative pressure inflated environment;

[0027] In the second step, the semi-finished product processed in the first step is cut into the required battery pole piece shape by laser cutting in a negative pressure inflatable environment.

[0028] In the above scheme, the negative pressure inflation environment is an environment with an air content of 99.9999% nitrogen, so that the environment is in a normal and safe negative pressure state, and at the same time, it also avoids the influence of other factors such as oxygen on the production and processing of battery pole pieces.

[0029] And the phy...

Abstract

The invention discloses a lithium battery pole piece preparation method. The preparation method comprises the following steps: S1, forming a semi-finished product with a metal coating on the surface of a metal base material through a physical vapor deposition method in a negative pressure inflation environment; and S2, cutting the semi-finished product treated in step S1 into a required battery pole piece shape by adopting a laser cutting mode in a negative pressure inflation environment. The provided a preparation method of the lithium battery pole piece solves the problem of oxidation of the battery pole piece in the processing process. The invention also provides a solid-state lithium battery.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a method for preparing a pole piece of a lithium battery and a solid-state lithium battery. Background technique [0002] With the increasingly prominent energy crisis and environmental pollution, people's demand for clean and renewable energy is becoming more and more urgent. In practical applications, renewable energy sources such as solar energy, wind energy, and hydropower need to be converted into secondary energy sources such as electric energy before they can be widely used by people. In order to solve the mismatch between natural renewable energy and power demand in space and time, the development of energy storage technology is essential. Among the many energy storage technologies, the electrochemical energy storage technology, that is, the use of batteries has attracted more and more attention. [0003] The traditional liquid lithium battery is also vividly ...
