BATTERIES THAT CHARGES ON AIR.pptx (Size: 335.21 KB / Downloads: 277) This article is presented by: PRASHANT KAUSHAL E.C FINAL YEAR BATTERIES THAT CHARGES ON AIR INTRODUCTION Lithium-ion batteries power most of the mobile devices like: Laptops Cell phones Portable Playstation. Merits of li-ion lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest energy density for weight. Because of the inherent instability of lithium metal, especially during charging, research shifted to a non-metallic lithium battery using lithium ions. The energy density of lithium-ion is typically twice that of the standard nickel-cadmium. Lithium-ion is a low maintenance battery, The high cell voltage of 3.6 volts allows battery pack designs with only one cell. lithium-ion cells cause little harm when disposed. Demerits of Li-ion It is fragile and requires a protection circuit to maintain safe operation. Subject to aging, even if not in use - storage in a cool place at 40% charge reduces the aging effect. Lithium ion batteries are energy limited. Li-air batteries Arthur Dobley, metal air battery scientist, explains “Li-air batteries breathe oxygen from the air, and allow it to react with the Li metal anode. These are constructed in layers, like a sandwich, of the lithium metal anode, separator with electrolyte and then the air cathode . the air cathode is the critical part, and that is where oxygen enters to cells and reacts.”
