Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
The concept of thin-film lithium-ion batteries was increasingly motivated by manufacturing advantages presented by the polymer technology for their use as electrolytes. LiPON, lithium phosphorus oxynitride, is an amorphous glassy material used as an electrolyte material in thin film flexible batteries.
This review summarizes the research on, and progress in such nanostructured thin-film electrode materials for lithium storage and for all-solid-state thin film batteries. Nanostructured thin film electrodes with various electrochemical reaction mechanisms based on nanometer-size effects, chemical composition and structure are summarized.
The electrode's material is one of the key components for perfecting lithium-ion batteries. It plays a crucial role in establishing the overall properties of the battery and presently is the main obstacle in fabricating the next generation of these batteries.
Recent reports of all-solid-state lithium batteries fabricated entirely of thin-film (<5 μm) components are relatively few in number, but demonstrate the variety of electrode materials and battery construction that can be achieved. More numerous are studies of single electrode films evaluated with a liquid electrolyte in a beaker-type cell.
For example, the thickness of a typical nanostructured thin-film electrode usually is less than 200 nm with a particle size smaller than 50 nm ( Fig. 1 a) . Such kinds of electrodes could significantly reduce the transportation and diffusion length of ions and electrons ( Fig. 1 b), thereby remarkably enhancing the kinetics of lithium storage.
