Biodegradable materials for energy storage

Are biodegradable polymers good for energy devices?

Energy devices based on biodegradable polymers can fulfill the original performance requirements during usage, maintain stability throughout their lifespan, and undergo chemical structure changes within a short period under natural conditions after use, resulting in performance degradation.

What are the challenges faced by biodegradable energy-storage devices?

One of the key unresolved challenges is the availability of power supply. To enable biodegradable energy-storage devices, herein, 2D heterostructured MoO 3 –MoS 2 nanosheet arrays are synthesized on water-soluble Mo foil, showing a high areal capacitance of 164.38 mF cm −2 (at 0.5 mA cm −2 ).

Can flexible biodegradable polymer-based energy devices provide energy for smart wearable devices?

However, employing flexible biodegradable polymer-based energy devices can convert the energy generated by human body movements into electrical energy through material properties such as piezoelectricity, frictional power generation, and electrostatic induction, thereby providing energy for smart wearable devices ( Fig. 1 ).
