Benefits of technology

The solution provides enhanced energy storage density per unit mass and volume, and improved charging rates for lithium ion and lithium-air batteries, addressing the limitations of prior art by optimizing the structure and materials used in the cathodes and electrolytes.

Problems solved by technology

For example, prior art cathodes used in lithium ion batteries suffer from low energy density (i.e. lithium cobalt oxide ˜180 mAh / g) when compared to the best available anode materials (silicon—4000 mAh / g).
One issue with the technique described in this paper is that the materials used to catalyze the reaction (gold), has a weight that creates an effective energy density of ˜300 mAh / g.
The technology also suffers from poor charging rates.

Embodiment Construction

[0041]FIG. 1A illustrates a cross section of a single element of an energy storage electrode 100, according to various embodiments of the invention. One or more of electrode 100 may be used in a rechargeable battery, such as the rechargeable (secondary) battery of FIG. 6, in accordance with various embodiments of the invention. The electrode 100 includes a substrate 110, an optional seed layer 115, and an energy storage system 190. The energy storage system 190 includes an underframe 130 and an active layer 150. The seed layer 115 may be used to initiate growth of the underframe 130 and may be used to facilitate connection of the energy storage system 190 to the substrate 110. In alternative embodiments the energy storage system 190 is coupled directly to the substrate 110. The underframe 110 supports the active layer 150, as well as the optional overlayer 154 and optional underlayer 152. The underframe 130 provides enhanced surface area per unit volume for uptake and / or deposition ...

Abstract

An energy storage device includes a nano-structured cathode. The cathode includes a conductive substrate, an underframe and an active layer. The underframe includes structures such as nano-filaments and / or aerogel. The active layer optionally includes a catalyst disposed within the active layer, the catalyst being configured to catalyze the dissociation of cathode active material.
