Batteries serve as a mobile source of power, allowing electricity-operated devices to work without being directly plugged into an outlet. While many types of batteries exist, the basic concept by which they function remains same one or more electrochemical cells convert stored chemical energy into electrical energy.
Batteries are divided into two main types they are primary and secondary. Primary batteries are disposable, are used once and rendered useless as the electrode materials in them irreversibly change during charging. Common examples are the zinc-carbon battery as well as the alkaline battery used in toys, flashlights and a multitude of portable devices.
Secondary batteries are rechargeable, can be discharged and recharged multiple times as the original composition of the electrodes is able to regain functionality. Examples include leadacid batteries used in vehicles and lithium-ion batteries used for portable electronics.
Graphene, a sheet of carbon atoms bound together in a honeycomb lattice pattern, is hugely recognized as a “wonder material” due to its miracle uses . A graphene battery can be light, durable and suitable for high-capacity energy storage, as well as shorten charging times.
It will extend the battery’s life, which is negatively linked to the amount of carbon that is coated on the material or added to electrodes to achieve conductivity, and graphene adds conductivity without requiring the amounts of carbon that are used in conventional batteries.
Graphene can improve such battery attributes as energy density and form in various ways.
Li-ion batteries can be enhanced by introducing graphene to the battery’s anode and capitalizing on the material’s conductivity and large surface area traits to achieve morphological optimization and performance
