Critical to the advancement of the battery is the emergence of higher quality separator film, new coatings of separator film for higher efficiency, and the uniform coating of the anode and cathode materials. But the coating thickness and weight must be optimal to ensure a longer-lasting and safer battery.
Separator film is one of the key components of a lithium ion battery. It is a thin but permeable layer of film used to separate the anode from the cathode and prevent short circuiting while facilitating the flow of charged ions. Separator films are usually produced either by a dry or wet process to create the required micro porous structure.
The mechanism of the thin-film batteries is that ions migrate from the cathode to the anode charging and storing absorbed energy and migrating back to the cathode from the anode during discharge and thereby releasing energy .
Thin-gauges and uniform thickness: Battery separator film (BSF) must be thin to facilitate the battery's energy and power densities. To support many charging cycles, its thickness must be uniform. Optimum porosity enables the electrolyte to be thoroughly moistened and ensures facile ionic conduction.
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].
Thin-film batteries have a wide area of applications covering the Internet of Things (IoT), implantable medical devices, integrated circuit cards, smart watches, radio-frequency identifier (RFID) tags, remote sensors, smart building control, astronomical mirrors and other wireless devices.
