Advancing sustainable development: Introducing a novel fast charging technique for Li-ion batteries with supercapacitor integration

Li-ion batteries play a vital role in today's world for their wide range of applications in electrical vehicles, mobile phones, electronic gadgets etc. Applying fast charging to Li-ion batteries is crucial for increasing consumer convenience, productivity, energy efficiency, and stimulating technical innovation across various industries. With the wide-spread usage of Li-ion batteries, it is critical to consider the environmental degradation caused by their decomposition. Therefore, solutions for fast charging Li-ion batteries must not only be reliable but also sustainable to meet future demands. This paper presents a novel Li-ion battery fast charging technology with an integrated supercapacitor and battery, for quick charging without shortening the battery's life cycle. The advantage of the proposed charger is that the supercapacitor assists the Li-ion battery while charging, thereby fast charging and improving the efficiency and longevity of the battery. The utilization of supercapacitor-assisted charging diminishes the burden on lithium-ion batteries, enhancing their lifespan and consequently reducing environmental harm. To validate the performance of the proposed charging technology, an experimental investigation has been carried out. The obtained results through the investigation show the increased performance of 82 % efficiency and 40 % longevity more than the conventional method. The proposed supercapacitor-based fast charging technique is not only efficient but also sustainable and reliable.
