Abstract There is an ever-increasing demand for the improvements in rechargeable Lithium secondary batteries owing to their high energy density, flexibility, cyclic stability and wide range of applications. Even though the science is often criticized for its slow progression, countless variations on the basic lithium chemistry are been investigated to address the safety and performance issues. The major components raising safety concerns are the volatile organic electrolytes and the dendrite forming Li metal electrodes. The present review covers the application of ionic liquid electrolytes in combination with the alloy anodes wherein these relatively advance Li ion battery components mutually benefits to overcome the existing issues related to cell efficiency as well as safety concerns. The essential understanding of lithiation/delithiation process as well as the SEI layer formation of alloy anodes in combination with Room temperature IL electrolytes is considered as an approach towards safer Li batteries.
