Abstract

The invention provides an in-situ electrochemical atomic force microscope for observing the surface interface of a variable temperature solid-state battery, including a battery fixture, the battery fixture includes a conductive plate and an insulating plate, the positive electrode of the solid-state battery is in contact with the conductive plate, and the negative electrode is in contact with the insulating plate. The feature is that the device also includes a temperature control device under the battery clamp, a protruding positioning device is provided on the side of the conductive plate facing the insulating plate, and a corresponding positioning device is provided on the side of the insulating plate facing the conductive plate. Positioning hole, after the positioning device is aligned with the positioning hole, the distance between the conductive plate and the insulating plate is equal to the thickness of the solid-state battery, preventing the solid-state battery from being over-extruded or unevenly stressed.

Description

technical field [0001] The invention belongs to the technical field of electrochemical testing, and in particular relates to a device for observing the surface interface of a temperature-changing solid-state battery with an in-situ electrochemical atomic force microscope. Background technique [0002] With the development of energy storage devices such as electric vehicles and portable electronics, solid-state lithium-ion batteries have become the preferred technology for next-generation energy storage devices due to their high energy density and power density, high safety and electrochemical stability. At present, there is no clear understanding of the interface reaction mechanism between electrodes and electrolytes in solid-state batteries and the failure mechanism of batteries in this field. Solid-state batteries have problems such as large interface resistance and interface side reactions. Electrochemistry-Atom Force Microscope (EC-AFM) is a new characterization techniqu...
