Abstract
The electrolyte material includes a polymer, a salt, and a solvent. The electrolyte material has a viscosity in the range from about 3.0 cP to about 20.0 cP such that the electrolyte material can be applied to a substrate using an ink jet print head.
Claims26
An electrolyte material comprising a polyimide polymer, a lithium salt, and a solvent, wherein the electrolyte material has a viscosity in the range from about 3.0 to 8.0 cP such that the electrolyte material can be applied to a surface in a layer using an ink jet print head.
An electrolyte adapted to be applied using an ink jet print head, comprising:
- from about 0.5% to about 2.5% by weight of a polyimide polymer;
- a lithium salt;
- and
- from about 80.0% to about 98.0% by weight of a solvent;
- wherein the electrolyte has a viscosity in the range from about 3.0 to 8.0 cP such that the electrolyte can be jetted by the ink jet print head.
A method of manufacturing a battery using an ink jet print head comprising the steps of:
- jetting an electrolyte material onto a surface, wherein the electrolyte material comprises a polyimide polymer, a lithium salt, and a solvent and has a viscosity in the range from about 3.0 cP to about 8.0 cP;
- and
- vaporizing a portion of the solvent.
