Electrode materials for lithium-ion batteries: Lithium-rich positive electrode materials
Continuing research and development to improve battery capacity, aiming for practical application! Here is an introduction to lithium excess type positive electrode materials.
We synthesized a lithium-rich positive electrode material with a certain chemical composition and also created a coating electrode ink using this positive electrode material. This ink was applied to an aluminum current collector to be used as an electrode, and a test lithium-ion battery was created using lithium metal as the counter electrode. A standard carbonate-based electrolyte was used, and the electrochemical characteristics were measured using conventional measurement methods for lithium-ion batteries. As a result, we were able to create a lithium-ion battery with a large capacity of approximately 265 mAh/g initially under a 0.1C current measurement condition, and it maintained 215 mAh/g even after 40 cycles. *For more details, please refer to the PDF document or feel free to contact us.

Company information
We are a chemical company that researches, develops, manufactures, and sells cutting-edge materials and technologies in the environmental and energy sectors aimed at building a decarbonized society. We are developing various advanced materials and technologies, including natural biomass-based biodegradable plastics (resins), biomass coating materials, biomass inks, next-generation solar cells, next-generation secondary batteries, next-generation fuel cells, quantum dots, metal-organic frameworks, ionic liquids, deep eutectic solvents, and cellulose nanofibers. Our original brand, Nano Sakura, under GS Alliance, significantly enhances the functional properties of raw materials by "compositing" cellulose nanofibers, which are the main component of plants, with various existing resin materials, resulting in an environmentally friendly, next-generation high-performance advanced material. We also offer products made from 100% natural materials derived from natural biomass waste resources such as wood, plants, bamboo, paper, recycled paper, seaweed, and starch, aiming for a grade with zero petroleum usage, striving to create materials that are as environmentally friendly as possible. We have been selected as a startup support program company by UNOPS, a United Nations-related organization. UNOPS S3i Innovation Centre Japan
