LR20 LR20 No. 1 Alkaline Zinc-Manganese Dry Battery Electric toys, electric shavers, gas water heaters.

Note: 1. R represents a cylindrical battery, and L indicates that the electrolyte in the battery is an alkaline liquid.

2. There are three types after the three models of R6, R14 and R20 plus S, C and P. For example, R6 has three types: R6S, R6C, and R6P. S is a paste-type battery, C is a high-capacity cardboard battery, and P is a high-power cardboard battery.

3. The S-type paste battery has low capacity, and it is easy to leak at the end of the battery, but it is cheap.

4. C-type (high-capacity) batteries are suitable for low-current discharge.

5. The discharge capacity of P-type (high-power) batteries has been greatly improved compared with the previous two, and this type of battery has good leakage resistance and is suitable for continuous discharge of high current.

6. The capacity of alkaline batteries is 3 7 times that of batteries of the same size mentioned above, and can be continuously discharged with large current, and has the characteristics of excellent leakage resistance.

1. Batteries are a kind of energy conversion and storage device, which converts chemical energy or physical energy into electrical energy through reaction. Depending on the energy converted by the battery, the battery can be divided into chemical and physical batteries.

2. A chemical battery or chemical power source is a device that converts chemical energy into electrical energy. It consists of two electrochemically active electrodes of different compositions of the positive and negative electrodes, and is made up of a chemical substance that can provide conduction as the electrolyte, and when connected to an external carrier, it provides electrical energy by converting its internal chemical energy.

3. A physical battery is a device that converts physical energy into electrical energy.

a) The working principle and application of galvanic batteries.

1. Galvanic battery: a device that converts chemical energy into electrical energy.

1) Formation conditions of galvanic cells: redox reactions that can be carried out spontaneously; Two electrodes with different activity; Electrolyte solutions or ionic compounds in a molten state.

2) The two poles of the galvanic battery: Negative electrode: a metal with strong activity, loses electrons and undergoes oxidation reaction; Cathode: A weakly active metal or a non-metal that conducts electricity, and undergoes a reduction reaction.

3) Electron flow direction of galvanic cells:

External circuit: the negative electrode provides electrons, and electrons flow from the negative electrode along the wire to the positive electrode (the direction of the current is the opposite direction of the electron flow);

Internal circuit: The negative electrode is continuously dissolved into the electrolyte solution, the anion moves to the negative electrode, and the cation moves to the positive electrode.

2. Judgment of the positive and negative poles of the original electric attack on the blue pool:

1) According to the electrode material: the metal with strong activity is the negative electrode, and the weak activity or non-metal is the positive electrode.

2) According to the flow direction of electrons or currents: electron flow direction: negative electrode positive electrode; Current direction: positive and negative.

3) Judging according to the change of electrode: oxidation reaction negative electrode; Reduction reaction of the cathode.

4) According to the phenomenon: the electrode dissolves the negative electrode; The weight of the electrode increases or there is a pat to lift the bubble to form the positive electrode.

5) According to the direction of ion movement in the electrolyte: the anion moves to the negative electrode; The cation moves towards the positive electrode.

Note: The liveliness of metals is affected by the environment. For example:

After MG is connected with AL, it is placed in hydrochloric acid, MG is the negative electrode, and Al is the positive electrode; Put it in NaOH solution, Al is the negative electrode and Mg is the positive electrode. Fe and Cu are connected and immersed in dilute Hno3, Fe is the negative electrode and Cu is the positive electrode; Immersed in concentrated HNO3, Cu is the negative electrode (Fe passivation) and Fe is the positive electrode.

A battery is a device for energy conversion and storage. It converts chemical or physical energy into electrical energy through reactions. The battery is a chemical power source, which consists of two electrochemically active electrodes of different compositions composed of positive and negative electrodes, and the two electrodes are immersed in an electrolyte that can provide conduction, and when connected to an external support, it provides energy by converting the chemical energy inside it.

As an electrical storage device, when two metals (usually metals with different properties) are immersed in an electrolyte, they can conduct electricity and generate a certain electromotive force between the "plates". The amount of electromotive force (or voltage) is related to the metal used, and different kinds of batteries have different electromotive force.

A battery is a portion of a cup, trough or other container or composite container that contains an electrolyte solution and metal electrodes to generate an electric current. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy. Such as solar cells.

The performance parameters of the battery mainly include electromotive force, capacity, specific energy and resistance.

Using the battery as energy, you can get a current with stable voltage, stable current, long-term stable power supply, and little influence from the outside world, and the battery structure is simple, easy to carry, simple and easy to charge and discharge, not affected by the external climate and temperature, stable and reliable performance, plays an important role in all aspects of modern social life, and accounts for a large proportion of electric energy use.

Alkaline batteries have good preservation, good leakage resistance, good temperature resistance, small voltage changes, stable voltage, and high efficiency discharge under high current, so both large and small currents are suitable for use. Carbon-zinc batteries are not suitable for some electronic machines that require voltage stability, small shape and high output, and high energy density, and are only suitable for lamps, lighting equipment, toys, etc. Alkaline batteries, only suitable for small current electrical appliances, such as clocks, water heaters, etc., are widely used, large and small current electrical appliances are applicable, large and small current electrical appliances are the same as electronic dictionaries, CD Walkman.

Chemical batteries, as large as a huge device that can fit in a building, and as small as millimeters, are concentrated in the field of chemical batteries that power electric vehicles.

The flashlight is lit, the battery car starts, the shaver turns, the toy car starts, the remote control is remotely controlled, and the mobile phone is turned on; iPads that run and are not plugged in require batteries.

Batteries are needed to store wind energy, solar energy, hydropotential energy, nuclear energy, and electricity storage.

The combination of numbers and shapes will be good, and the fairy is not nervous, I think it's okay, and the crazy cool game.

I'm sure everyone has dealt with essays, especially expository essays, which are important to illustrate the characteristics, essence, and regularity of things by revealing concepts. What makes a good expository essay? Here's what I've put together for all of you.

Hazard Statement, I hope it can help everyone.

So, is there any harm in batteries? It's safe to say, "Yes, absolutely!"

If you still don't believe me, let me tell you!

In fact, the harm of waste batteries is like an atomic bomb, which may be at any time, as long as it is within the range, it will definitely be attacked by its powerful "attack", which will affect your health and risk your life. Relevant information shows that if a No. 1 battery rots in the ground, 1 square meter of land will permanently lose its use value; A single coin cell battery can pollute 600 tons of water, which is an amazing number! This amount of water is equivalent to the amount of water that a person drinks in his life, and the battery contains mercury, lead, cadmium and other heavy metals, among which mercury is a heavy metal with strong toxicity and great destructive power to the central nervous system of the human body. Lead, on the other hand, can cause lead poisoning, etc.; Cadmium can cause osteoporosis, etc.

If waste batteries are buried in the soil together with household garbage, or discarded, the leaching mercury and heavy metal mascots will penetrate into the soil, pollute groundwater, damage the living environment of human beings, and threaten human health.

Students, how about it, after my introduction, you should know the dangers of waste batteries. In the future, it is necessary to throw the waste electric cover into the battery box.

Summary. The working principle of the battery: during the discharge process of the battery, the negative electrode undergoes an oxidation reaction to provide electrons to the outside; The reduction reaction is carried out on the positive electrode, the electrons are received from the external circuit, and the electrons flow from the negative electrode to the positive electrode, and the direction of the current is exactly opposite to the direction of the electron flow, so the current flows from the positive electrode to the negative electrode through the external circuit.

The working principle of the battery: during the discharge process of the battery, the negative electrode undergoes an oxidation reaction to provide electrons to the outside; On the positive electrode, the reduction is reversed, receiving electrons from the external circuit, and the rubber infiltration causes the electrons to flow from the negative electrode to the positive electrode, and the direction of the current is exactly the opposite direction of the electron flow, so the current flows from the positive electrode to the negative electrode through the external circuit.

This happens because the controller is damaged. As soon as this happens, it is advisable to replace the controller immediately. The controller is used to control the circuit of the whole vehicle.

Without a controller, an electric car cannot function properly. The controller is generally fixed under the back seat. Electric vehicles are a relatively simple means of transportation.

Its main components include the frame, motor, controller, and battery. Motors are used to provide power. An electric motor can propel an electric vehicle forward.

Batteries are the part of the electricity that electric vehicles use to store electricity. The battery can power all the electronic devices on an electric vehicle.

Batteries are also consumable parts and need to be replaced regularly.

As the number of charge and discharge increases, the performance of the battery will deteriorate. During charging and discharging, the ions in the battery move in the electrolyte, and some ions react with the electrolyte when they move in the electrolyte. As the number of charge and discharge increases, the number of ions in the battery decreases, and therefore the performance of the battery decreases.

If you can maintain the correct driving habits, you can effectively extend the service life of the battery.

When charging, be sure to use a suitable charger to prevent the battery from overcharging. If you don't need to use the car for a long time, you should also charge the battery regularly, otherwise it will cause the battery to run out.
