Abstract
An example composition is disclosed. For example, the composition includes a ultra-violet (UV) curable mixture of water, an acid, a phosphine oxide with one or more photoinitiators, a water miscible polymer, a salt, and a neutralizing agent. The composition can be used to form an electrolyte layer that can be cured in the presence of air when printing the thin-film battery.
Claims18
A composition, comprising:
- an ultra-violet (UV) curable mixture comprising water, an acid, a phosphine oxide, a water miscible polymer, a salt, and a neutralizing agent;
- and
- a cross-linker comprising triethylene glycol divinyl ether (TEGDVE).
A battery, comprising:
- a cathode layer;
- an anode layer;
- and
- an electrolyte layer coupled to the cathode layer and the anode layer, wherein the electrolyte layer comprises a cross-linked polymer and phosphine oxide, wherein the cross-linked polymer is formed from a mixture of water, an acid, the phosphine oxide with one or more photoinitiators, a water miscible polymer, a salt, a neutralizing agent, and a cross-linker comprising triethylene glycol divinyl ether (TEGDVE) that is consumed during curing under a UV light to form the electrolyte layer.

A method, comprising:
- printing an electrode layer;
- dispensing an electrolyte layer precursor composition onto the electrode layer, wherein the electrolyte layer precursor composition comprises water, an acid, a phosphine oxide, a water miscible polymer, a salt, a neutralizing agent, and a cross-linker comprising triethylene glycol divinyl ether (TEGDVE);
- and
- ultraviolet light curing the electrolyte layer precursor composition in presence of air to form an electrolyte layer.
