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.
