Abstract

Claims (21)

1 . A lightweight high power battery, comprising:

an active structure including:

an anode electrode having a first side and a second side opposite the first side;

a first metal layer formed on the first side of the anode electrode;

a cathode electrode having a first side and a second side opposite the first side;

a second metal layer formed on the second side of the cathode electrode; and

a separator material arranged between the second side of the anode electrode and the first side of the cathode electrode;

a liquid electrolyte; and

a non-metallic pouch arranged to encapsulate the active structure and the liquid electrolyte, wherein the non-metallic pouch is bonded to a first portion of the first metal layer, the first portion being positioned between the non-metallic pouch and the anode electrode, and

wherein the non-metallic pouch is bonded to a second portion of the second metal layer, the second portion being positioned between the non-metallic pouch and the cathode electrode.

2 . The lightweight high power battery of claim 1 , wherein the non-metallic pouch comprises a material that binds to both a metal and itself.

3 . The lightweight high power battery of claim 1 , wherein the battery has a weight less than 1 gram.

4 . The lightweight high power battery of claim 3 , wherein the battery has a weight less than 300 mg.

5 . The lightweight high power battery of claim 1 , wherein the battery has a power density of at least 1 kW/kg for a duration of at least one second.

6 . The lightweight high power battery of claim 1 , wherein the battery has an irregular shape.

7 . The lightweight high power battery of claim 1 , wherein the first metal layer comprises copper.

8 . The lightweight high power battery of claim 1 , wherein the second metal layer comprises aluminum.

9 . A lightweight high power battery, comprising:

an active structure including an anode electrode, a single cathode electrode, and a separator material arranged between the anode electrode and the single cathode electrode;

a liquid electrolyte; and

a non-metallic pouch arranged to encapsulate the active structure and the liquid electrolyte and comprising a top layer and a bottom layer, wherein the active structure is positioned between the top layer and the bottom layer of the non-metallic pouch.
