KRI proposes development of next generation battery materials related development by holding base technologies. We help resolve issues that can not be solved with materials alone and support matching issues with other materials and components by collaborating with material engineers and battery engineers.
Next-generation battery materials related development
●Proposal for the practical realization of Li2MnO3 series solid solutions
- ・Capacity of 300 mAh / g (twice as high as commercialized positive electrode materials）
- ・Capable of obtaining high capacity even for the charging and discharging times of around 30 minutes to a few hours required for practical use. (Japanese Patent No. 5781411)
●Target of next-generation cathode material
- ・Successful synthesis of Li2NiO3 series material through high temperature and high pressure technology with the verified formation of a laminated structure.
- ・Confirmation of primary particles with a diameter of several 10 nm and capacities exceeding 200 mAh / g
●Structural design of PAHs negative electrode material
- ・Analysis of the correlation between lithium storage state and battery characteristics for the structural design of high capacity PAHs
- ・An approach to control the state of carrier and localized electrons
- ・An approach to achieving microstructural control regarding the reversibility of lithium
Proposal from KRI
- ●Application study of thin layer Si material (2000 mAh / g class) to battery
Thin film Si material of around 5 μm: A capacity of 5 mAh / cm 2 is obtained. Please consult us for this project proposal by collaboration.
- ●Target of next-generation cathode material
We will pursue materials comparable to Li metal (2060 mAh / cc).
- ・Development of high capacity material of C2Li or higher with polyacene negative electrode material (PAHs: 2680 mAh / cc)
