Yes. but it isn't the only metal used for batteries.
Zink
They reduce the use of metal used to make them. (i.e. when you get disposable batteries the metal is disposed) but if you recharge batteries, it will reduce the costs of making.
Nickel Metal Hydride or Lithium Ion batteries are the most widely used.
The metal used in a flashlight battery is typically zinc. Zinc-carbon batteries and alkaline batteries are common types of batteries used in flashlights, both of which contain zinc as a key component in their construction.
Nickel Metal Hydride or Lithium Ion batteries are the most widely used.

Lead
Yes. It's used in Nickel Cadmium and Nickel Metal Hydride batteries.
The strong gray metal used in the manufacturing of some types of batteries is lithium. It is commonly found in lithium-ion batteries, which are known for their high energy density and rechargeable properties.
