Opinion About Increasing use of Li-Air Batteries |Biomedgrid

Currently, conventional lead-acid and lithium-ion batteries are inappropriate to withstand conditions and requirements of industrial applications, such as in high-range electric vehicles and electro-mobile devices such as cell phones and laptops. To meet the storage requirements of electrical energy, batteries must develop a higher energy density. The batteries that are currently dominating the field of electromobility are Li-ion batteries. To achieve a requirement of high energy density, metal-O2 mainly Zn-O2, Al-O2, Li-O2 batteries (O2 is taken from the air) are attractive as an alternative, to the fact that these have a high theoretical energy density. Metal-O2 batteries are characterized by oxygen, one of their electroactive materials. Given that oxygen is an electroactive material, in theory this simplifies the design and increases the energy density of a battery cell. For metal-O2 batteries, there are different technologies based on using different metals as an anode, for example: Ca, Al, Fe, Cd and Zn [1]. Interest has been directed more towards Zn-O2 and Li-O2 batteries, of which research into Zn-O2 batteries is considered to be a sufficiently mature technology, and most of their applications are regarded as stationary or in primary batteries, i.e., non-rechargeable batteries. Currently, there are primary batteries with Zn-O2 technology.
