Lithium ion batteries as an energy storage device have achieved a great attention in specially portable electronic devices and electric vehicles. But due to the use of volatile and flammable liquid organic electrolytes in batteries, may improve safety issues such as fire and explosion. In order to address these safety risks, all solid-state lithium batteries have been developed in the past years, but due to low ionic conductivities of electrolytes, cause the reduction in usage in many industrial applications. As a compromise strategy, gel polymer electrolytes can be use with combined advantages of both high ionic conductivity and safety.
The overall objective of the project is to develop polymer based gel electrolyte to be used in the application of rechargeable Lithium ion batteries together with Sri Lankan vein graphite based anodes developed from the National battery research center located at the National Institute of Fundamental Studies, Kandy. This research work focused on to develop novel materials to be used in the current technology of batteries with readily available, sustainable and low-cost materials in order to improve the overall performance of the device focusing on the ionic conductivity and specific capacity improvements. This research findings can be further developed through a research and development phase in order to fabricate a rechargeable Lithium ion battery for commercial purposes.
