In this article we will discuss about the design of high voltage and low voltage atomic batteries with the help of suitable diagrams. Design of High Voltage Atomic Battery: Fig. 9.28 shows the schematic diagram of a high voltage atomic battery. It consists of an inner spherical electrode on the surface of which is deposited a powerful beta emitting (i.e., [...]
In this article we will discuss about:- 1. Container of Lead-Acid Batteries 2. Plates of Lead-Acid Batteries 3. Active Materials. Container of Lead-Acid Batteries: The materials of which the battery containers are made should be resistant to sulphuric acid, should not deform or become porous, or contain impurities deterious to the electrolyte; of these iron and manganese are especially intolerable. [...]
The following types of special charges are usually required for proper maintenance of secondary batteries: 1. Boosting Charge: Though batteries are usually of sufficient capacity to work for the whole day without requiring any intermediate charge during the day, but in some cases such as in battery operated vehicles, however, the batteries may require an extra charge known as “boosting [...]
There are three important characteristics of an accumulator (or storage battery) are: 1. Voltage 2. Capacity 3. Efficiency. Characteristic # 1. Voltage: Average emf of cell is approximately 2.0 volts. The value of emf of a cell does not remain constant but varies with the change in specific gravity of electrolyte, temperature and the length of time since it was [...]
In this article we will discuss about the working of lead-acid battery with the help of diagram. When the sulphuric acid is dissolved, its molecules break up into hydrogen positive ions (2H+) and sulphate negative ions (SO4- -) and move freely. Now if two lead electrodes are immersed in this solution and connected to dc supply mains, the hydrogen ions [...]
In this article we will discuss about:- 1. Methods of Charging Lead Acid Battery 2. Types of Charging Lead Acid Battery 3. Precautions during Charging 4. Charging and Discharging Curves 5. Charging Indications. Methods of Charging Lead Acid Battery: Direct current is essential, and this may be obtained in some cases direct from the supply mains. In case the available [...]
