Battery manufacturing is the process of making batteries by assembling cells and putting them into a battery casing. The most common type of battery is the lead-acid battery, which is made by combining lead and sulfuric acid. Other types of batteries include lithium-ion batteries, nickel-cadmium batteries, and nickel-metal-hydride batteries.
Some of the emerging trends in battery manufacturing include the use of nanomaterials for lithium ion batteries, the use of graphene for lithium ion batteries, and the use of solid-state batteries.
