    Which materials are used in making battery of an automobile?


    Have a query about automobile batteries? Wondering which material is used to make the battery? Here, you can go through the responses from experts and know more about the material which are used to make this battery.

    The automobile is a need of the hour and transportation by road is not possible by trucks, buses, cars our bikes. Each one uses the battery for certain operations.

    Car batteries came into use from around 1920 and cars are provided with electric starters. The sealed battery was invented in 1971.
    The first starting and charging systems were designed with a 6-volt and positive-ground systems keeping the vehicle's chassis connected to the positive battery terminal. Today, all road vehicles are using a negative ground system. The negative battery terminal is connected to the car's chassis.
    Cars used a 6 V electrical system until the mid-1950s. The 6V system is changed to 12 V when bigger engines with higher compression ratios.
    In the past, batteries required maintenance in the form of electrolyte refills. Modern batteries retain their fluid for the life of the battery. Absorbed glass mat (AGM) batteries are more capable of deep discharge, but they are costly
    Batteries are typically made of six galvanic cells in a series circuit. Each cell provides 2.1 volts for a total of 12.6 volts at full charge. Each cell of a lead storage battery consists of alternate plates of lead (cathode) and lead coated with lead dioxide (anode) immersed in an electrolyte of sulfuric acid solution.,
    The main materials required are an outer shell, lead plates, Lead dioxide coated lead plates and sulfuric acid of required concentration.

    The main constituents of a automobile battery are two lead electrodes (anode and cathode) submerged in a solution of sulphuric acid.

    Lead is used to make the electrodes with one of the electrode coated with lead oxide. For better exposure area for electrochemical reaction between lead and sulphuric acid the plates are designed in a flat grid style and each cell is capable of generating about 2 volt and 6 such cells in series will suffice to give 12 volt which is the general standard in automobiles. The complete system is kept in an acid resistant enclosure. Two electrical terminals are provided on outside for electrical connections to the vehicle.

    Nowadays sealed batteries are available and there is no need to top up electrolyte time to time.

    Thoughts exchanged is knowledge gained.

    Automobile battery contains lead and lead oxide electrodes immersed in sulphuric acid electrolyte. The reaction between the lead and sulphuric acid creates EMF between the electrodes which is used as the electrical supply in form of a 12 volt DC.

    In the old type of batteries electrolyte was to be filled against the decrease in the level of acid but now sealed batteries are available where the electrolyte does not dry up till the age of the battery.

    In a running vehicle the battery is continuously charged from the current from the alternator and if a vehicle does not run for a long time then the battery may not be able to start the car and may need to be charged from an outside repair and maintenance shop.

    Knowledge is power.

    Which materials are used in making of a battery of an automobile?

    Automobile batteries power the starting of engine, basic light, fan, radio and stereo functioning when the car's engine is switched off.
    The current batteries have lead and lead dioxide coated plates in sulfuric acid electrolyte solution wherein the lead acts as anode and the coated plate acts as cathode.As electricity is used from the battery, lead sulfate is formed which reverts back to lead dioxide when we charge the battery.

    What is the alternative to it?
    The alternative would be the new future concepts in battery technology. The are light weight and charge lasts for a much longer time.

    Few vehicles will have a lithium ion battery. There are alos solid state batteries being developed like the Graphene based hybrid batteries.

    Gold nanowire batteries have been developed by University of California.

    A new non flammable battery has been developed using copper foam substrate.

    Store dot charger based on biological semi-conductors are currently being used to charge a mobile phone in 60 seconds.

    In the lithium-ion batteries, the negative electrode is made of graphite, a form of carbon, the positive electrode is made of a metal oxide, such as lithium cobalt oxide, and the electrolyte is a lithium salt dissolved in an organic . There are a range of materials being used in batteries for electric vehicles. Lithium-ion batteries are utilized in the majority of all-electric and plug-in hybrid electric vehicles, nickel-metal-hydride are common for hybrid cars; and newer materials are being introduced, such as lithium polymer and lithium iron phosphate, with more on the horizon to challenge those in commonly used.
