Porous microspheres consisting of carbon-modified LiFePO 4 grains prepared by a spray-drying assisted approach using cellulose as carbon source

摘要: Porous microspheres composing of carbon-modified LiFePO4 (C/LFP) nanoparticles have been prepared successfully by a spray-drying process combined with calcination step using cellulose as carbon source. LiOH plays duple roles agency for dissolving aqueous solution and source lithium LiFePO4. The synthesized C/LFP composite are rich in porosity, all the consist numerous grains diameter about 200 nm. In addition, individual encapsulated matrix derived from cellulose. cladding enhances electronic conductivity LiFePO4, while porous structure shortens Li+ diffusion distance facilitates penetration electrolyte when composites used cathode material battery. Hence, unique delivered an initial specific discharge capacity 165 mAh g−1 showed good rate performance.
