All-solid-state lithium-ion batteries (ASSBs) have garnered attention for their high energy density and superior safety.

Inconsistent results led to another discovery — that ... anode (the bottom-emitting device has a reflecting cathode and a transparent anode). At CDT we have had a focused top-emission device ...

but the split anode arrangement differs slightly from the microwave in your kitchen. The idea is to make a heated filament the cathode, so electrons are ejected from the hot surface by thermionic ...
