Abstract

The invention provides a solid-state electrochemical component, a solid-state electrochemical device and a preparation method of the solid-state electrochemical component. The solid-state electrochemical assembly includes a solid-state electrochemical functional layer and a plastic crystal interlayer in physical contact with the solid-state electrochemical functional layer, the plastic crystal interlayer including a plastic crystal matrix and an ion conductive compound and an additive dispersed in the plastic crystal matrix. The assembly, the solid-state electrochemical device, and the methodof preparing the same of the present invention improve interface resistance between an electrode and a solid-state electrolyte.

Description

technical field [0001] The present invention relates to the field of electrochemistry, and in particular to an electrochemical component suitable for a solid-state electrochemical device, a solid-state electrochemical device (such as a battery, a capacitor, etc.), a method for preparing the component, and a method for preparing a solid-state electrochemical device. In particular, the present invention relates to all-solid-state electrochemical devices, which means that the electrochemical devices do not contain electrolytes in a liquid state, and that the electrolytes are all solid-state. Background technique [0002] Lithium-ion batteries (LIBs) have been used as power sources for portable electronic devices since the late 1990s. More recently, they have also been used to power electric vehicles. However, these devices contain flammable and volatile organic liquid electrolytes, and when the batteries are mismanaged, they can catch fire, emit harmful gases, and even explode...
