A high-voltage, all-solid-state lithium-ion thin-film battery composed of LiNi 0.5 Mn 1.5 O 4 cathode, a LiPON solid electrolyte, and a lithium metal anode has been deposited layer by layer on low-cost stainless-steel current collector substrates.
Thin-film lithium-ion batteries have the ability to meet these requirements. The advancement from a liquid to a solid electrolyte has allowed these batteries to take almost any shape without the worry of leaking, and it has been shown that certain types of thin film rechargeable lithium batteries can last for around 50,000 cycles.

High-Performance Solid-State Lithium Metal Batteries of Garnet/Polymer Composite Thin-Film Electrolyte with Domain-Limited Ion Transport Pathways The integrated approach of interfacial engineering and composite electrolytes is crucial for the market application of Li metal batteries (LMBs).
In a thin film based system, the electrolyte is normally a solid electrolyte, capable of conforming to the shape of the battery. This is in contrast to classical lithium-ion batteries, which normally have liquid electrolyte material. Liquid electrolytes can be challenging to utilize if they are not compatible with the separator.
A final protective film is needed to prevent the Li-metal from reacting with air when the batteries are exposed to the environment. The typical energy densities that can be achieved for these thin-film cells are 3.6 J·cm −2 (1 mWh·cm −2).
All-solid-state thin-film lithium batteries (TFBs) with high voltage are crucial for powering microelectronics systems. However, the issues of interfacial instability and poor solid contact of cath...
