Abstract
Provided is apparatus for introducing a quasi-solid electrolyte into one or a plurality of lithium battery cells, the 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 injects 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 from the battery cells so that the electrolyte has a final lithium salt concentration higher than the first concentration and higher than 2.0 M. Also provided is a method of operating the apparatus.
