Abstract

The invention discloses an independently packaged reference electrode suitable for a lithium ion battery. The reference electrode comprises a shell, a current collector, a pin, an electrode, an interface stabilizing layer, a packaging layer and a packaging cover; the shell is a cylinder or a cuboid; the current collector is connected with a bottom of an inner cavity of the shell, the electrode isconnected with an upper side of the current collector, the interface stabilizing layer is connected with the upper side of the electrode, and the packaging layer is connected with the upper side of the interface stabilizing layer; the packaging cover is connected with the top of the shell; and in use of the reference electrode, the packaging cover is removed, thus, the packaging layer is communicated with electrolyte of the lithium ion battery, and the pin stretches out the shell of the lithium ion battery and is connected with a detection external circuit. With the reference electrode provided by the invention, industrialization and large-scale form of the reference electrode are promoted effectively, stability, consistency and interchangeability of product performance are improved, and production cost of enterprises is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to an independently packaged reference electrode suitable for lithium ion batteries. Background technique [0002] Lithium-ion batteries are widely used in the fields of electric vehicle power batteries and large energy storage batteries due to their excellent characteristics such as high energy density, high output voltage, low self-discharge rate, long service life, no memory effect and environmental friendliness. With the development of electric vehicles, the market has higher and higher requirements for the power batteries used in electric vehicles. The batteries used in the existing power batteries and energy storage batteries are mainly laminated. , current collector, electrolyte, casing and other components are basically the same structure as the lithium-ion battery used in portable 3C devices. [0003] However, power batteries and energy storage batteries are ...
