A Low-cost And A High Power Rechargeable Aqueous Aluminum-graphite Battery.
Project Description :

The ever-growing popularity for harnessing renewable energy has given a massive boost in the research of cost-effective and easily scalable rechargeable battery technologies, lead acid and lithium(li)-ion batteries have been dominating the global battery market due to their some of the remarkable merits. in particular, li-ion battery is regarded as the powerhouse of modern portable electronic gadgets due to its high energy density, miniaturized size, and longer durability. however, the scarcity and high-cost of the essential ingredients for the fabrication of lithium batteries are now emerging to be major industrial setbacks. moreover, the safety issues of li-ion batteries are also a matter of concern for its widespread use in transportation. therefore, it is becoming quite imperative to develop alternative battery technologies based on earth-abundant and green materials. hence, we report a low-cost rechargeable aluminum-graphite using aluminum foil as anode and graphite sheet as cathode. the electrochemical performance was performed in 1 m aqueous electrolyte (aluminum chloride). the unique chemistry uncovered in this work ensure the production of aluminum-graphite battery in the future. the assembled aluminum-ion battery exhibited a discharge potential of 1.8 v and the initial discharge capacity of 250 mahg-1. although the work hints at obtaining a rechargeable aluminum battery with a graphite cathode in aqueous electrolyte, it also unveils certain intricacies associated with it. notable are the low cycle life stability and continuous fall of the storage capacities. nevertheless, the advantages of this type of rechargeable battery will be beneficial for powering small household utilities.
