US Patent 7462419 - Microscopic battery with ion transmitting electrolyte

This patent from Bipolar Technologies has some early priority (3/10/1998) and teaches an electrolytic microfabricated battery structure. Claim 1 reads:

1. A microfabricated battery comprising:

a system for internal storage of electricity comprising reactants,

the microfabricated battery having a volumetric size which is microscopic including a micrometer footprint substantially less than 20 cm2 and congruent with a microelectronic circuit accommodating integration with the circuit to provide long term stored power and to materially limit power losses,

the microfabricated battery comprising a body of material having:

a first microfabricated electrode of chemically reactant material,

a second microfabricated electrode spaced from the first electrode and

a microscopic amount of internal ion-transmitting electrolyte which restricts electronic current flow and accommodates reactions at the electrodes contained within an internal microfabricated space in the body accessible to both electrodes.
