Review on poly(ethylene oxide)-based electrolyte and anode nanomaterials for the internet of things node-level lithium-ion batteries

Abstract

Long lifetime, small size, and rechargeability are the most Internet of Things (IoT) node-level batteries requirements. At the IoT node-level, the power management unit is the most important part through which the battery gets recharged through an energy investment mechanism where it is applicable. The IoT device life is determined by its battery life, so the battery chemical materials play a major role in producing a good battery to be utilized for IoT different applications. The lithium-ion batteries (LIBs) of secondary type are considered good candidates for IoT node-level usage due to their rechargeability and the developments in their membrane and anode with the help of nanotechnology. The current paper objective is to review those developments in terms of poly(ethylene oxide) (PEO) electrolyte (as a membrane) and anode nanomaterials in order to provide a research direction towards the batteries materials side rather than the software side which is the current way for obtaining long-life batteries in the IoT domain.
