Abstract

A high-performance rechargeable battery using ultra-fast ion conductors. In one embodiment the rechargeable battery apparatus includes an enclosure, a first electrode operatively connected to the enclosure, a second electrode operatively connected to the enclosure, a nanomaterial in the enclosure, and a heat transfer unit.

First claim

The invention claimed is:

1. A rechargeable battery apparatus, comprising:
an enclosure,
a first electrode operatively connected to said enclosure wherein said first electrode is an electro-catalytic anode,
a second electrode operatively connected to said enclosure wherein said second electrode is an oxygen cathode,
a suspended flowing material in said enclosure wherein said suspended flowing material comprises nanoparticles and wherein said suspended flowing material is directly connected to said first electrode wherein said first electrode is an electro-catalytic anode,
an electrolyte and separator between said first electrode and said second electrode,
an oxygen selective membrane between said first electrode and said second electrode,
a suspended flowing material storage tank containing said suspended flowing material wherein said suspended flowing material storage tank is connected to said enclosure by flow lines for flowing said suspended flowing material into and out of said enclosure,
a pump for circulating said suspended flowing material from said suspended flowing material storage tank into and out of said enclosure, and
a heat transfer unit connected to said suspended flowing material in said suspended flowing material storage tank.

2. The rechargeable battery apparatus of claim 1 wherein said nanoparticles are lithium nanoparticles.

3. The rechargeable battery apparatus of claim 1 wherein said nanoparticles are lithium alloy nanoparticles.

4. The rechargeable battery apparatus of claim 2 wherein said nanoparticles are hydrides as a source of hydrogen ions.

5. The rechargeable battery apparatus of claim 1 wherein said nanoparticles are lithium nanoparticles or lithium alloys nanoparticles or a mixture of lithium nanoparticles and lithium alloys nanoparticles.

6. The rechargeable battery apparatus of claim 2 wherein said nanoparticles are intercalated graphite or carbon aerogel as a Li source.

7. The rechargeable battery apparatus of claim 2 wherein said nanoparticles are intercalated transition metal oxide as a Li source.

8. A rechargeable battery apparatus, comprising:
an enclosure,
a first electrode operatively connected to said enclosure wherein said first electrode is an electro-catalytic anode,

a flowing material in said enclosure wherein said flowing material comprises nanoparticles and wherein said flowing material is directly connected to said first electrode wherein said first electrode is an electro-catalytic anode,
an electrolyte and separator between said first electrode and said second electrode,
an oxygen selective membrane between said first electrode and said second electrode, and
a circulation system for circulating said flowing material into and out said enclosure, said circulation system including
a storage tank containing said flowing material wherein storage tank is connected to said enclosure by flow lines for flowing said flowing material into and out of said enclosure,
a pump for pumping said flowing material from said storage tank into and out of said enclosure,
a heat transfer unit connected to said flowing material in said storage tank.

9. The rechargeable battery apparatus of claim 8 wherein said nanoparticles are lithium nanoparticles.

10. The rechargeable battery apparatus of claim 9 wherein said nanoparticles are hydrides as a source of hydrogen ions.

11. The rechargeable battery apparatus of claim 9 wherein said nanoparticles are lithium nanoparticles or lithium alloys nanoparticles.
