That depends on the type of battery. There are nickel cadmium, lithium, lead acid,
LEAD
Lead
Lead.
Nickel Metal Hydride or Lithium Ion batteries are the most widely used.
lead
Lead (Pb) is commonly used in electrodes in car batteries as it forms lead-acid batteries, which are known for their reliability and low cost. Lead is a heavy metal that can store and release electrical energy efficiently in this application.
Yes. but it isn't the only metal used for batteries.
lead
Lead is the primary element used in metal plates of car batteries, as it is a cost-effective material that can efficiently store and release electrical energy through chemical reactions in the battery. Lead-acid batteries are commonly used in cars due to their reliability and ability to provide the high currents needed for starting a vehicle.
Zink
Lead is the metal present at both the cathode and anode in a car battery, as it is used in both the positive and negative plates of lead-acid batteries.
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.
