In recent years, demands for high-performance lithium-ion batteries have increased along with the expansion of their usage. The high electrical conductivity of active materials is essential for lithium-ion batteries to provide stable and improved performance. However, metal oxides currently used as cathode materials suffer from stable operation due to the low electrical conductivity of ceramic materials. In this study, we tried to supplement the low electrical of cathode materials by introducing the carbonized pitch with high carbon contents and low cost, as a conductive material. Two types of pitch with different softening points were analyzed to investigate their suitability as conductive material. The pitch with a higher softening point showed better properties and improved initial charging/discharging efficiency by 29.2% when applied to commercial cathode electrodes with LiCoO₂.

Artificial intelligence is being used in a variety of fields, including medicine. But their lack of interpretability and explainability stand as one of the main drawbacks. To solve this problem, explainable artificial intelligence has been studied in healthcare. In this paper, we summarize recent advances in explainable artificial intelligence technologies and introduce the use of explainable artificial intelligence studies in medicine.
