The advancement of electronic devices, such as electric vehicles and drones, has led to an increased focus on battery research. Lithium-ion batteries are widely used for their high energy density and long cycle life. However, using liquid electrolytes in these batteries presents several challenges, including leakage risks, flammability, and the formation of dendrites, which can lead to safety hazards and reduced battery performance. Solid electrolytes offer several advantages, such as enhanced safety, prevention of leakage, and suppression of dendrite formation. These benefits can potentially address the issues associated with liquid electrolytes. However, solid electrolytes also face challenges, including difficulties in manufacturing, lower ionic conductivity, and mechanical stability issues, which hinder their commercialization. Uniform distribution of lithium ions within solid electrolytes is crucial to ensure consistent performance and prevent the formation of hotspots that can lead to battery failure. Electrochemical Strain Microscopy (ESM) is a powerful technique that can analyze ion concentration and conductivity by detecting the strain generated in the material due to ionic movement. When applied to solid electrolyte materials, ESM provides valuable insights into the uniformity of ion distribution and ion conduction pathways. This capability is particularly beneficial in developing and optimizing solid electrolytes, where understanding and controlling ion distribut...
