Recent Innovations Advancing Thin Film Battery Developments

Electronic devices are an integral part of human life, serving a multitude of functionalities. Many application areas—for example, electronic gadgets, health monitoring and medical devices, activity tracking, smart cards, and wearable electronics—require lightweight, flexible, and compact energy storage solutions. The focus on miniaturization and compactness in electronic devices has catalyzed the need for said solutions. Thin film batteries address the critical needs of the industry by providing reliable, lightweight, compact, and portable energy storage that enables self-powering devices.

Thin film Batteries are electrochemical energy storage devices typically fabricated by layer deposition of active battery material and are differentiated by their compact and flexible form factor as opposed to conventional cylindrical, or prismatic batteries. These batteries typically utilize a non-aqueous, polymer-based electrolyte that also functions as a separator by electronically disconnecting both electrodes—the cathode and the anode. As a result, thin film batteries do not require an additional separator material. Additionally, the non-aqueous electrolyte allows the battery to be flexible and conform to various shapes as the geometry of the application area necessitates, leading to much better space utilization.
