The ability to accumulate the charge and the ability to recharge batteries into a separate class of devices, widely used both in production and in everyday life. Slide 4. The last years of the twentieth century are the years of the wide distribution of such portable devices, like players, pagers, cell phones, various portable computers, etc. As a source for them, it is not only convenient to use batteries, but also it is impossible to use anything else. Despite some differences, all batteries for portable electronic devices are inherent in many common properties: a large capacity (the battery must work for a long time without recharging), small size and weight (person using this device must be easily and convenient to carry it), high reliability ( Batteries should not be susceptible to various shocks, shakements, temperature drops, etc.). All these requirements are satisfied with the lithium-metall - hydride batteries Slide 5. Slide 6. In addition to the wide propagation of batteries in frequent devices, the battery has found its main application in the automotive industry. In cars, it is used for the initial start of the engine. Despite the general lower indicators of the latter compared to the lithium-metall - hydride, it is leading batteries in cars due to ease of use, relative cheapness and simply automotive traditions. Slide 7. Slide 8. For quite a long time, humanity is trying to build an electric car, working not on liquid fuel, but on electric current. The main advantage of the electric vehicle compared to the usual car is environmental purity. The source of the current should be large batteries of batteries. Incen due to the size of the batteries, the electric vehicles still did not become serious competitors of cars on gasoline or diesel fuel. Slide 1.

All these requirements are most satisfied with lithium-metal hydride batteries. Slide 5. Slide 6. If earlier the computer was a tool for scientists, then he was currently published in everyday life and in business. In the latter case, an important data may be lost with a sudden disconnection of electricity, which will lead to serious losses. If this happens with a large server, then the consequences can even be disastrous. So that this does not happen, use the uninterruptible power supply (UPS) source, the most important element of which is the battery. The requirements for it are several others than to the battery for portable devices. The battery must work for a long time without recharging and should give voltage enough to normal operation of the computer at its outputs. For it, sometimes the output power is 500 W and more. Slide 7. In addition to the wide propagation of batteries in the above devices, the main use of the battery has found in the automotive industry. In cars, it is used for the initial start of the engine. Despite the general lower indicators of the latter compared to lithium metal-hydride, it is lead batteries that use lead batteries due to ease of use, relative cheapness and simply automotive traditions.

Italian scientist Luigi Galvani (1737-1798) opened the possibility of obtaining electric current other than electrification by friction of batteries Once, when he conducted a study of frogs, he noticed that when touched a steel scalpel to the nerve, the paw was a dead frog in motion. In the future, Galvani put several experiments to detect the cause of the occurrence of electric current and translas The principle of batteries is based on the electrolysis phenomenon. Electrolysis is a change in the chemical composition of the solution when the electric current is passed through it, due to the loss or addition of electrons by ions. An important property of electrolysis is its reversibility. E lecturer Similar to the galvanic element, you can make a battery. To do this, use two lead plates immersed in a solution containing one part of sulfuric acid and five parts of water. To charge the battery, it is connected in series with an ammeter and passed through a circuit current. Battery manufacturing The charging process is that two identical battery plates due to electrolysis become different; One of them, negative, still remains lead, and the material of another (positive) turns into lead peroxide. When the electric current battery passes on the cathode, hydrogen bubbles are released on the cathode, and oxygen is released on the anode. Due to the fact that a certain amount of oxygen is chemically connected to the material of the anode plate, it gradually acquires a dark brown color due to the formation of lead peroxide on its surface. Charging process When forming the charging current drops, which indicates an increase in the internal resistance of the battery. If the battery is fully charged, the voltmeter attached to it will show a voltage of a few more than 2 volts. Charging Tok The following chemical reactions occur in the battery (in the process of charging the reaction, go to the left right, when discharged - in the opposite direction): Charging\u003e Positive plates in the production of industrial batteries are covered with a thick layer of lead peroxide. Negative plates are made of porous spongy lead. In a conventional battery consisting of three successively connected battery elements, the voltage is a little more than 6 volts. The efficiency of the battery is approximately 75%. On the rechargeable battery put a number that shows the number of electricity stored in the battery, expressed in amps - industrial batteries For example, 120 amps-hours means that with a complete discharge, the battery will be able to give a current of 1 amps for 120 hours, or a current of 2 amps for 60 hours. It is necessary to constantly maintain the battery in the charged state. Even if the battery is not in operation, it should be regularly recharged. It is necessary to contain clips of batteries clean and protected from corrosion. Neither should be allowed to freeze batteries. Ampere - hours Basically, rechargeable batteries are used to start motor engines and other machines. It is also possible to use as temporary sources of electricity in places remote from settlements. It must be remembered that the batteries should be maintained in the charged state, applying for this, for example, solar energy. In the future, the batteries expect to be used to power eco-friendly electric motors.
