Abstract
Disclosed herein are energy harvesting devices and methods of making and use thereof. The energy harvesting devices can efficiently harvest energy for motions at a frequency of 5 Hz or less.
Claims18
An energy harvesting device comprising:
- a first electrode comprising a first material;
- a second electrode comprising the first material;
- wherein the first material comprises a plurality of particles and a plurality of ions;
- wherein the plurality of ions are intercalated within the plurality of particles;
- and
- wherein the plurality of ions comprise a plurality of alkali metal ions;
- a porous separator disposed between the first electrode and the second electrode such that the porous separator is in contact with the first electrode and the second electrode, wherein the porous separator further comprises an electrolyte;
- and
- wherein the energy harvesting device is configured to convert a mechanical strain to an electrical current, thereby harvesting energy.
