They also should have a relatively smooth surface. Each component of the thin-film batteries, current collector, cathode, anode, and electrolyte is deposited from the vapor phase. A final protective film is needed to prevent the Li-metal from reacting with air when the batteries are exposed to the environment.
Sator reported the first thin film cell in 1952 ; it featured a lead chloride electrolyte deposited by vacuum evaporation. Then, the first Li-ion thin film batteries (AgI||LiI||Li) were reported in 1969 . Over the next 20 years, the primary focus of research was on enhancing the performance of SSEs and electrode materials.
For thin-film battery systems, surface coatings are a simple and effective method. Introducing coating materials onto the surface of Ni-rich layered oxides avoids direct contact with the electrolyte, thus minimizing the parasitic reactions. It also sets a kinetic barrier to O 2 evolution.
The higher rate performance is ascribed to the inherently faster Li-ion kinetics due to chlorine doping. This shows the importance of obtaining a large specific capacity with an enlarged surface area and using high-rate performance electrode materials. Therefore, silicon and tin are also widely used in 3D thin film batteries.
All solid-state thin-film batteries (TFLIBs) have been produced by various deposition techniques. These techniques efficiently avoid microscopic defects at the solid-solid interface and minimize barriers at the junctions. TFLIBs exhibit high stability, a long cycle life, a wide operating temperature range, and a low self-discharge rate.
