Flexible Li-ion batteries (LIBs) have a strong oncoming consumer market demand for use in wearable electronic devices, flexible smart electronics, roll-up displays, electronic shelf labels, active radio-frequency identification tags, and implantable medical devices. This market demand necessitates research and development of flexible LIBs in order to fulfill the power requirements of these next generation devices. One of the main areas of research and development of high performance flexible LIBs is the active and inactive materials used in manufacturing these batteries. Active materials are those materials used in the battery electrodes that can store lithium ions in their structure. The remaining materials used in manufacturing flexible…show more content…
As explained by IDTech Ex report that the flexible electronics market will reach over $76 billion by 2023[1],while the market for flexible, thin, stretchable and bendable batteries will grow to become about $471 million industry by 2026[2]. Additionally, the product is considered the most promising energy storage device with low carbon dioxide emission. The energy density of the lithium ion battery range between 120-170 Wh Kg-1 and 250-380 Wh l-1 more higher than Ni-Cd and Lead-acid[3]. LIB has three major electronically active components namely anode, electrolyte, and cathode. The anode is the negative electrode that releases electrons into an external circuit during a discharge process that involves the oxidation of chemical reactions. On the other hand, the cathode is the positive electrode that is reduced during a reaction. Notably, the lithium ions are stored within the cathode after a cell is discharged. Both cathode and anode stores energy while on charge, and releases it on discharge[4]. Cathode materials have relatively high electrochemical potentials while anode materials have low potentials. This design approach helps maximize the battery’s output voltage. The final active component of the LIB is the electrolyte. It is a mixture of a set of organic solvents containing disassociated lithium salts that enables Li+ transportation between the anode and the cathode. Besides, other complementary components, such as current collectors attached to the
