SPM (AFM) Measurements of Cathode and Anode Materials from All-Solid-State Lithium-Ion Batteries without Exposure to Air

User Benefits

- SPM (AFM) observations and measurements can be performed without exposure to air. - The cathodes and anodes of all-solid-state lithium-ion batteries can be observed and measured. - Shapes can be observed at the microscopic scale, and current and electrical forces can be visualized.

Introduction

Further improvements to battery performance are called for due to policies promoting electric vehicles (EV). This includes expectations for the commercialization of all-solid-state lithium- ion batteries because of their advantages including safety, high energy density, and resistance to degradation. One issue in the practical utilization of such batteries is the difficulty of reducing the interface resistance between the electrodes and the solid electrolyte. However, it is believed that shape observations and measurements of current at the microscopic scale will lead to a better understanding of interface reaction mechanisms leading to the resolution of this issue. This article introduces examples of surface observations of cathode and anode materials and measurements of current in all-solid-state lithium-ion batteries using SPM.
