Q:

What are different kinds of batteries?

A:

Common types of batteries include zinc-carbon, alkaline, lithium-ion and lead-acid batteries. Zinc-carbon and alkaline batteries are most often used as small household batteries. Lithium-ion batteries are used in rechargeable devices such as cell phones and laptops, while lead-acid batteries are most often used in vehicles.

The difference between these battery types is the chemical composition. Different anodes, cathodes and electrolytes give each battery type a different performance profile. This affects their electrical output, useful life and ability to recharge.

Zinc-carbon and alkaline batteries both use zinc for the anode and magnesium dioxide for the cathode. The difference between the two is the electrolyte: alkaline batteries use potassium hydroxide for their electrolyte and zinc-carbon batteries use ammonium chloride. Alkaline batteries derive their name from their electrolyte, which is highly alkaline.

Lithium-ion batteries do not have one single chemistry. They all utilize some form of lithium for the cathode, but electrolytes and anodes vary. The most common variety of lithium-ion battery uses lithium cobalt oxide for the cathode and carbon for the anode. The electrolyte is a lithium salt dissolved in an organic solvent.

Lead-acid batteries use lead dioxide for the cathode and metallic lead for the anode. The electrolyte is sulfuric acid. This combination is where lead-acid batteries get their name.

    How can button cell batteries be recharged?

    A:

    Button cell batteries that are used in hearing aids, cameras and watches are considered single-use and therefore recharging should not be attempted. Lithium ion coin cell batteries, which are larger and flatter than button cell batteries, can be recharged.

  • Q:

    How do I wire two 12-volt batteries together?

    A:

    Wiring two 12-volt batteries together depends on the application it needs to be used in. If double the voltage from 12 to 24 volts is needed , the batteries are wired in series (negative, positive wired to negative, positive). If 12 volts are needed, the batteries are wired in parallel (positive wired to positive and negative wired to negative).
