Thin-film batteries are solid-state batteries comprising the anode, the cathode, the electrolyte and the separator. They are nano-millimeter-sized batteries made of solid electrodes and solid electrolytes. The need for lightweight, higher energy density and long-lasting batteries has made research in this area inevitable.
Kanazawa and coworkers recently prepared thin-film batteries consisting of amorphous vanadium oxide with lithium phosphorus oxide (VO-LiPO), Si, and LiPON as cathode, anode, and electrolyte materials, respectively 102.
The aim for batteries in any size or shape, without the restrictions liquid components pose, has led to the development of solid elec- trolyte systems. All-solid-state thin-film batteries add a new dimension to the space of battery applications.
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.
The purpose of this thesis is to assess the application potential for solid-state thin-film batteries, particularly with regard to CMOS integration. Such batteries were developed with the aim of creating a power unit on a silicon microchip. The various degrees of integration of thin-film batteries on a silicon wafer are examined.
In addition, the durability of thin film lithium-ion batteries may be advantageous in other applications that involve temperatures that the human body cannot withstand . Radiofrequency identification (RFID) tags are employed in logistics and stock management and are frequently included in discussions of the Internet of Things (IoT) [83, 84].
