Abstract: Ionic cyclic nitroxyl radical oligomers, methods of making the ionic cyclic nitroxyl radical oligomers, and electrochemical cells, such as aqueous organic redox flow batteries (AORFBs) that use the ionic nitroxyl radical oligomers as catholytes are provided. The oligomers are larger than individual cyclic nitroxyl radical molecules, but maintain a high density nitroxyl radical groups within the molecule. As a result, when the oligomers are used as catholytes in an AORFB, they are able to reduce catholyte permeation through the ion-conducting membrane, while providing a high volumetric capacity and cycling stability.

Abstract: A portable lighting device including a shell, at least one luminous element, a lens component, a battery compartment, positive and negative terminals, at least one indicator mark disposed on the battery compartment, and light-transmitting channels is provided. The battery compartment is made of transparent and fluorescent materials. The indicator mark is used for indicating the positive or negative terminals. The light-transmitting channels allow the light emitted by the luminous element to irradiate and stimulate the battery compartment to emit light and exhibit an afterglow. Thus, by using the light from the battery compartment to illuminate the indication mark, the user can accurately determine the positive and negative terminals in the battery compartment in a dark environment, which is convenient to replace batteries or battery pack.
