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.

Single-particle electrode  measurement for the first time shows capability of precise electrochemical measurement for ~10 μm NMC/NCA single cathode particles. It can be regarded as a breakthrough in the electrode materials characterization,the level of measurement technology has been at the top of the world. This technology has successfully revealed the long-standing scientific problems such as the rate-limiting factorsaging mechanisms in Li-ion battery electrode materials.

Single-particle electrode material measurement provides battery materials R&D with a new functional characterization tool, which can precisely (1) measure electrode materials properties, (2) evaluate development efficiency,(3) verify electrode performance . With the single-particle technology, R&D people can identify the core development problems for advanced electrode materialsfurther propose solutions, so as to greatly improve R&D efficiencymake breakthroughs.
