Claim 0:
1. Apparatus for introducing a quasi-solid electrolyte into one or a plurality of lithium battery cells, said apparatus comprising:
(a) a cell-holding device to hold one or a plurality of lithium battery cells and is in a working relation to a liquid electrolyte-filling device that is configured to inject a liquid electrolyte into the battery cells, wherein the liquid electrolyte comprises a lithium salt dissolved in a first liquid solvent having a first lithium salt concentration from 0.001 M to 3.0 M (mole/L); and
(b) a solvent vapor-removing device in a working relation to the cell-holding device, wherein the vapor-removing device comprises a pumping device to move solvent vapors away form the battery cells so as to form the quasi-solid electrolyte having a final lithium salt concentration higher than the first concentration and higher than 2.0 M,
wherein said solvent vapor-removing device further comprises a vaporization device, vacuum degassing device, centrifugal degassing device, centrifugal vacuum degassing device, gas-liquid separation membrane, or a combination thereof.
