Description
Summary:Thin‐Film Lithium‐Ion Batteries In article number 2309183, Ji‐Won Jung, Sang‐Jin Lee, Hyun‐Suk Kim, and co‐workers focus on developing miniaturized thin‐film lithium‐ion batteries (TF‐LIBs), specifically addressing the challenge of low energy density in these batteries. The study introduces an innovative design for SiOx‐based thin‐film electrodes, closely resembling traditional lithium‐ion battery (LIB) slurry formulations, which include an active material, a conductive agent, and a binder. A key innovation of this research is the use of mid‐frequency (MF) sputtering to create a singular hybrid thin‐film composed of SiOx nanoparticles, several conductive agents, and a strong binder made of plasma‐polymerized fluorocarbon (PPFC). Our design, which is analogous to SiOx‐based thin‐film electrodes, proposes a new approach to TF‐LIB fabrication.
