WebAluminium–air battery. Aluminium–air batteries (Al–air batteries) produce electricity from the reaction of oxygen in the air with aluminium. They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using traditional electrolytes. WebThe lead-acid batteries and lithium ion batteries are common examples of rechargeable electrical battery. Disposable batteries. Chemistry: Anode (−) Cathode (+) Nominal voltage (V) Specific energy (MJ/kg) Zinc–carbon: Zn: ... The chemical equations for the zinc–air cell are: The chemical reaction at the anode ...
