The performance of Li-ion batteries mainly depends on electrode active material properties. However, the advanced characterization of obtaining the essential electrode materials properties is extremely required for electrode materials R&D. We developed the world＇s first single-particle electrode measurement, which shows precise electrochemical measurements of obtaining the essential electrode materials properties. Single-particle electrode measurement will become the vital characterization technology for electrode materials R&D in Li-ion batteries as well as advanced rechargeable batteries.

The present invention relates to a solid sodium carbon dioxide battery, which can utilize carbon dioxide gascan chargedischarge at room temperature. This solid carbon dioxide battery is composed of a positive electrode, a negative electrode,an inorganic solid electrolyte sheet. In order to improve the contact between the electrodethe inorganic solid electrolyte sheet, a positive/negative interface layer can also be introduced.
