Highly sensitive 2D organic field-effect transistors for the detection of lithium-ion battery electrolyte leakage†
Abstract
Lithium ion batteries (LIBs) have become indispensable in daily life. Here, we fabricated a broad range of polymer semiconductor films as thin as 2 nm via a standard spin-coating method, and utilized the resulting organic transistors for the detection of LIB electrolytes, which can give an early warning signal before LIB failure.
