Pre-Lithiation Strategies for Rechargeable Energy Storage Technologies:…

- - - - Accurate prelithiation but the evaporation of the electrolyte solvents, the high reacctivity of the Li metal foil.
    - - two half cells using Li2SO4 solution instead of active Li metal.
        4.2h=4200 mAh/g
        a high overpotential of 0.3V during prelithiation
        the LISICON film is expensive
        to scale up?
  - - - 50% of the total capacity in 20 min.
        it's difficult to control the degree.
    - - on the surface of electrodes.
        added into the paste(toluene/xylene + pvdf,SBR).
        dispersion isn't stable
        dry room condition
        changed the fabrication system (aqueous system)
  - - - a thick SEI (thicker and brittle), no Li ion insertion (due to the high redox potential of n-BuLi of 1 V). Irreversibel capacity changed from 340 to 256 mAh/g.
    - - immersion of 72 h, OCV=0.21 V, d-Li =670 mAh/g
    - - comparison of solvents, 3h for complete lithiation for butyl methyl ether
    - - 45% to 56%
  - - - mixing Si NPs/SiOx and Li metal foil at 200℃ for 6h in glove box
- - - - Li2S-KB-PVP slurry was coated on the surface of a LiFePO4 electrode
  - - - n-BuLi
        LiI: mix and heat the pristine material with LiI (washed by acetonitrile)
    - - in a Li metal cell
