Studying battery cycling on the beamline

During his Ph.D. with TUoS, ISIS facility development student Innes McClelland developed a cell for testing battery materials during their operation using muon spectroscopy and used it to study an increasingly vital cathode ...

The world's first fluorosulfate-based flame retardant additive

In lithium-ion batteries commonly used in electric vehicles, incombustible additives are added to the electrolyte in preparation for the possibility of ignition. ETRI researchers succeeded in developing a fluorosulfate-based ...

A cathode is an electrode through which electric current flows out of a polarized electrical device. Mnemonic: CCD (Cathode Current Departs).

Cathode polarity is not always negative. Although positively charged cations always move towards the cathode (hence their name) and/or negatively charged anions move away from it, cathode polarity depends on the device type, and can even vary according to the operating mode. In a device which consumes power, the cathode is negative, and in a device which provides power, the cathode is positive:

An electrode through which current flows the other way (into the device) is termed an anode.
