Imperial College London researchers have designed polymer electrode materials to provide better stability for lithium-ion batteries and address problems with organic electrode molecules, such as the ...

As electronics demand higher energy density, one component has proved challenging to shrink: the capacitor. Making a smaller ...

Scientists develop positive electrode material using an organic redox polymer based on phenothiazine. Aluminium-ion batteries containing this material stored an unprecedented 167 milliampere hours per ...

Researchers have pushed sodium-ion battery charging speeds into territory once reserved for lithium-ion cells, demonstrating ...

Per- and polyfluoroalkyl substances (PFAS) are persistent pollutants that have contaminated drinking water supplies around the world. Scientists and regulators would like to easily detect these ...

A recent breakthrough in electrode technology addresses one of the key limitations of lithium iron phosphate (LFP) ...

For decades, microelectrodes have faced a challenge in balancing conductivity with tissue compatibility. Rigid metal or silicon-based electrodes enable stable signal recordings but often damage the ...

Today’s lithium-ion batteries use liquid electrolytes that can catch fire if a battery overheats. Solid electrolytes made of nonflammable polymers and ceramics are safer, but their performance isn’t ...

Microbial bioelectronic sensors use living bacteria that can create an electrical signal in response to the presence of a target substance, or analyte. These types of sensors offer many advantages ...
