Executive Summary :

An ideal battery means safer, smaller and powerful further, it will not combust, even when punctured, twisted, or heated. A great market has been anticipated for the flat batteries in electronic industries, for powering sensors, medical devices, powered cards, and wearable. The Internet of things (IoT) is all about installing sensors for everything and connecting them to the internet for information exchange, monitoring and management. Today, the electronic market is undergoing drastic change driven by the emergence of new addressable market categories such as wearable electronic devices, health monitors, medical implants and Internet of things. Powering a wide variety of electronic devices and IoT in a wide variety of domains that are tiny, inaccessible is challenging. Life of Power storage should be same as the life of the product. Conventional batteries present a number of problems that make them unsuitable for wearable and similar IoT devices. Alternate option is SSBs which are free from hazardous chemicals or sparking, besides they possess high charge density, low power discharge and high rechargeable cycle capacity. Micropower sources have become indispensable in electronic industry as well as for important sensor monitors, lifesaving medical implants, strategic defence and information technology applications. Today, the number of smart devices (things) connected to the internet is exceeding at a great phase. For such emerging markets new power solutions is necessary and for this, batteries that are small, thin, self-recharging, and never need replacement is in demand. Conventional Li-ion batteries use liquid-based electrolytes are bulky and cannot be integrated with electronic devices. Alternate solution would be solid state rechargeable batteries (SSB) combined with renewable source or wire-free charging at remote locations. The project is aimed to develop sodium ion based solid electrolytes coupled with high electrochemical performance electrodes in thin film form for fabricating SSBs. Sodium ion over lithium ion is chosen as the later is less abundant, poor reserves in India and costlier. Prototype SSBs will be designed, fabricated and tested at lab scale.
