However, compared to other battery types, the toxicity of alkaline batteries is moderate. Alkaline batteries contain zinc (Zn) and manganese dioxide (MnO 2) (Health codes 1), which is a cumulative neurotoxin and can be toxic in higher concentrations. In Switzerland, alkaline batteries account for 68%, in the UK 60% and in the EU 47% of all battery sales including secondary types. In Japan, alkaline batteries account for 46% of all primary battery sales. Other battery systems also use alkaline electrolytes, but they use different active materials for the electrodes.Īlkaline batteries account for 80% of manufactured batteries in the US and over 10 billion individual units produced worldwide. The alkaline battery gets its name because it has an alkaline electrolyte of potassium hydroxide (KOH) instead of the acidic ammonium chloride (NH 4Cl) or zinc chloride (ZnCl 2) electrolyte of the zinc–carbon batteries. Typically these batteries derive energy from the reaction between zinc metal and manganese dioxide.Ĭompared with zinc–carbon batteries of the Leclanché cell or zinc chloride types, alkaline batteries have a higher energy density and longer shelf life, yet provide the same voltage. Different batteries have different discharge rates.Size comparison of alkaline batteries (left to right): C, AA, AAA, N, PP3 (9-volt).Īn alkaline battery (IEC code: L) is a type of primary battery where the electrolyte (most commonly potassium hydroxide) has a pH value above 7. Typically, the longer the discharge time, the more energy produced.
It is the current supplied by the battery, measured in amperes, multiplied by the number of hours the battery can supply that amount of current. The discharge rate of batteries is expressed in ampere-hours.

Higher voltages may be obtained by connecting several cells in series so that their voltages add together. The voltage of a single cell is about 1.5 volts. The battery can be reused ad recharged many times. A secondary battery is a battery that can be recharged by regenerating the electrodes inside the cell. When the electrodes are fully consumed after much use, the battery can no longer generate electricity. When the battery is connected to a circuit, a chemical reaction takes place within the cell and current flows through the circuit. The electrodes are submersed in the electrolyte. All chemical cells contain three main parts: a positively charged electrode called the cathode a negatively charged electrode, called the anode and a chemical substance, called an electrolyte. Before that time, only static electricity an innovation with no practical value could be produced.Ĭhemical batteries convert chemical energy into electrical energy by means of a chemical reaction, which consumes the metal within the cell.
The Italian scientist Alessandro Volta invented the first electric battery in about the year 1800. Batteries are used to provide energy for devices from space satellites to trucks, to radios.
