Working of Lead Acid BatteryThe storage battery or secondary battery is such a battery where electrical energy can be stored as chemical energy and this chemical energy is then converted to electrical energy as and when required. The conversion of electrical energy into chemical energy by applying external electrical source is known as charging of battery. Whereas conversion of chemical energy into electrical energy for supplying the external load is known as discharging of secondary battery.Dur

Applications of ElectrolysisElectrolytic Refining of MetalsThe process of electrolytic refining of metals is used to extract impurities from crude metals. Here in this process, a block of crude metal is used as anode, a diluted salt of that metal is used as electrolyte and plates of that pure metal is used as cathode.Electrolytic Refining of CopperFor understanding the process of electrolytic refining of metals, we will discuss about an example of electrolytic refining of copper. Copper extracte

There are mainly two parts in a lead acid battery. The container and plates.Lead Acid Battery ContainerAs this battery container mainly contains sulfuric acid hence the materials used for making a lead acid battery container must be resistant to sulfuric acid. The material container should also be free from those impurities which are deterious to the sulfuric acid. Especially iron and manganese are intolerable.The glass, lead lined wood, ebonite, hard rubber of bituminous compound, ceramic mater

Electrolyte of Lead Acid BatteryThe electrolyte of a lead acid battery cell is a solution of sulfuric acid and distilled water. The specific gravity of pure sulfuric acid is about 1.84 and this pure acid is diluted by distilled water until the specific gravity of the solution becomes 1.2 to 1.23. However, in some cases, the specific gravity of diluted sulfuric acid is recommended by the manufacturer of the battery depending upon the type of battery, season, and climatic conditions.Chemical Actio

Ionization is a fundamental concept in chemistry and physics that describes the transformation of electrically neutral atoms or molecules into electrically charged ones. Ionization occurs when an atom or molecule gains or loses one or more electrons, resulting in a positive or negative charge. The charged atom or molecule is called an ion.Ionization can happen in various ways, such as through collisions, chemical reactions, or exposure to electromagnetic radiation. Ionization plays an important

Batteries can be quite heavy. This disadvantage prevents batteries from being a source of energy in many different appliances and applications where being lightweight is crucial.An aluminum air battery overcomes this issue. It uses air as a cathode, significantly reducing its weight.In an aluminum air battery, aluminum is used as an anode, and air (the oxygen in the air) is used as cathode. This results in the energy density – i.e. energy produced per unit weight of the battery – very high compa

Working Principle of BatteryA battery works on the oxidation and reduction reaction of an electrolyte with metals. When two dissimilar metallic substances, called electrode, are placed in a diluted electrolyte, oxidation and reduction reaction take place in the electrodes respectively depending upon the electron affinity of the metal of the electrodes. As a result of the oxidation reaction, one electrode gets negatively charged called cathode and due to the reduction reaction, another electrode

Which battery is becoming more popular day by day as there is a huge scope of development to turn the battery into high energy density battery for an electric vehicle? The answer would be Nickel Iron Battery or Edison Battery. In a single word, a Ni-Fe battery is a very robust battery. This battery has a very high tolerance for overcharging, over discharging, short-circuiting, etc. This battery can perform equally well even we do not charge the battery for a long period. Due to its heavy weight,

Batteries have become one of the most important and most used equipments these days. Batteries are used where the power supply is not regular, where low voltage is required (i.e. lower than supply voltage); watches, mobiles and many other small types of equipment that require lesser voltage, mainly run on battery. The main advantage of the battery is that they can be charged and used if the capability of supplying power reduces. Cells are the unit of battery, many cells complete a battery. There

Battery CellsBattery is an electrical element where electrical potential is produced due to chemical reaction. Every electrochemical reaction has its limit of producing electric potential difference between two electrodes.Battery cells are those where these electro-chemical reactions take place to produce the limited electric potential difference. For achieving desired electric potential difference across the battery terminals multiple numbers of cells are to be connected in series. Hence it can
