Batteries are used in many day-to-day devices such as cellular phones, laptop computers, clocks, and cars. Batteries are composed of at least one electrochemical cell which is used for the storage and generation of electricity. Though a variety of electrochemical cells exist, batteries generally consist of at least one voltaic cell.
Batteries are used to store chemical energy. Placing a battery in a circuit allows this chemical energy to generate electricity which can power device like mobile phones, TV remotes and even cars. Generally, batteries only store small amounts of energy. More and more mobile devices like tablets, phones and laptops use rechargeable batteries.
Batteries are devices that use chemical reactions to produce electrical energy. These reactions occur because the products contain less potential energy in their bonds than the reactants. The energy produced from excess potential energy not only allows the reaction to occur, but also often gives off energy to the surroundings.
Electrochemical cells can range in number from one to many in a battery. Two electrodes are present in every electrochemical cell, and an electrolyte separates them. One electrode produces electrons as a result of the chemical process occurring inside the cell. When the electrons start travelling, electricity is created.
When a battery is created, a larger voltage is produced, since the voltages from the individual cells are combined. Non-rechargeable batteries have limited reactants. Non-rechargeable batteries use a specific number of reactants. The reactants are found in small amounts within these non rechargeable batteries.
Batteries are a non-renewable form of energy but when rechargeable batteries store energy from renewable energy sources they can help reduce our use of fossil fuels and cut down carbon dioxide and greenhouse gas production. Find out why batteries may have a key role to play in making our energy supply greener.
