| 제목 | Synthesizing rock-salt structured for high energy density Cathode Material by Sol-gel Method |
| 초록 | Secondary batteries have gradually risen to prominence as the mobile devices, electric vehicle, laptop, and energy storage devices. Lithium-ion battery’s(LiBs) market is gradually increasing by 10% every year. There are many studies into increasing LiBs performance; the energy density, cycle life, stability and cost effectiveness. The main way of increasing the energy density of LiBs is to use electrode material that exhibit high capacities owing to battery material structure. However, commercial lithium-ion batteries are mostly layered, olivine, and spinel structured, these structures do not allow the maximum lithiation/delithiation of lithium-ions. We are studying new structured battery material. Recently, layered Li-excess cathode material can deliver much higher capacities compare with traditional layered Li-material through the design of more lithium-ion space. This design notwithstanding a new structure; the rock-salt structure can accommodate more lithium-ions compared to the above-mentioned structures. We designed rock-salt structured lithium-ion cathode materials, Li3NbO4, on a nanoscale by sol-gel method. Based on the rock-salt structured material, Li3NbO4 was doped with Ni2+ ions to increase the energy density. We will evaluate Ni-dope Li3NbO4 cathode material by XRD, SEM and Electro-property. |
