Abstract
A flexible energy storage device with a glycerol-based gel electrolyte is provided. The flexible energy storage device can include a pair of electrodes separated by the gel electrolyte. The electrolytes can be in gel form, bendable and stretchable in a device. The gel electrolyte can include glycerol, redox-active molybdenum-containing ions, and a secondary ionic substance. The secondary ionic substance can include a salt. The gel electrolyte can have a density of 1.4 to 1.9 g/cm3 and an ionic conductivity of 2.3×10−4 to 3.2×10−4 Scm−1. The flexible energy storage device may retain greater than 95% of an unbent energy storage capacity when bent at an angle of 10 to 170°.
Claims13
A flexible energy storage device for galvanostatic charge-discharge, comprising:
- a pair of electrodes separated by a gel electrolyte, the gel electrolyte comprising glycerol, redox-active molybdenum-containing ions, and a secondary ionic substance,
- wherein the glycerol is present in an amount of 40 to 98 wt %, based on a total weight of the gel electrolyte, and the redox-active molybdenum-containing ions are molybdate anions present in an amount of 1 to 25 wt %, based on a total weight of the gel electrolyte, and
- a gel electrolyte support disposed between the electrodes, wherein the gel electrolyte is embedded in and penetrates the gel electrolyte support and the gel electrolyte support is in the form of a film,
- wherein the flexible energy storage device retains greater than 75% of an unbent energy storage capacity when bent at an angle of 10 to 170°.
