Lithium-ion batteries have been the nucleus of the digital-modernization,especially when acknowledging the exponential rise in the digital-dependency of society on mobile devices.As they play such a vital role, over the years various efforts have been made to increase there capacity, cyclability and battery life with higher safety measures.At present,LiCoO2 cathode batteries with carbonaceous anode and LiPF6/EMC electrolyte is the most commonly used Li-ion battery. However the toxicity of Co,low cyclability of carbon and the inflammable nature of EMC demand the next generation Li-ion battery with enhanced performance and safety measures to take its place commercially to meet the high demand of the society which is possible at nanoscale using LiFePO4 and silicon-nanowires as the electrodes with an inorganic electrolyte(fluid SO2) that is incombustible in nature.The following content briefly explains the challenges faced by the current generation of Lithium-ion batteries and the recent progress made to tackle the said problems.
