1. Preface In the manufacturing process of lithium batteries, compaction density significantly influences battery performance. Generally, compaction density is closely related to the specific capacity, efficiency, internal resistance, and cycling performance of the battery. Identifying the optimal compaction density is…
1. Technical Features and Validation of Solid-State Batteries The fundamental characteristics of solid-state batteries are consistent with those of liquid batteries, and the evaluation criteria remain unchanged regardless of battery type. The development of solid-state batteries requires careful attention to…
1. Author Information and Article Summary In 2020, Jan-Patrick Schmiegel et al. installed a a gas sampling port (GSP) on the lithium-ion pouch cell, in-situ to realize the battery gas composition analysis of different charging times, different voltage states, different…
1. Preface Electrochemical measurement methods, which assess electrical quantities such as potential, conductivity, and current, explore the relationship between these measurements and the system being analyzed to achieve qualitative and quantitative analysis of system components. Common electrochemical measurement methods include…
1. Preface In the field of electrochemistry, battery testing equipment is a key tool for researching and developing new battery technologies, especially for emerging battery technologies. As new energy technologies advance rapidly, the importance of high-precision testing equipment becomes increasingly…
