Defining role of the surface and bulk contributions in camphoric carbon grafted lithium nickel manganese oxide powders for lithium ion batteries

摘要: Abstract In the present study, lithium nickel manganese oxide powders grafted with camphoric nano-carbons have been exploited to fabricate high voltage, capacity rechargeable electrodes for Li storage. The prepared particles were pyrolyzed using a solution graft porous carbon layer on surface. A detailed study was performed elucidate effect of content performance electrode. Relative contributions capacitive and diffusion-controlled processes underlying these composite mathematically modeled. composites showed two times higher conductivity as compared pristine samples. These exhibited specific value ~154 mAhg -1 good rate capability. fading found be ~17% at end 200 cycles 100% depth discharge. retention blends ~10% ~40% respectively than which are promising considering their low cost facile fabrication process.
