What kind of battery is called a lithium battery, is it in the shape of a garden cake for watches?

The garden cake-shaped battery used for the watch is a silver-zinc battery, commonly known as a button cell battery, which is a primary power supply.

The "lithium batteries" mentioned by LS are actually lithium-ion batteries, not lithium batteries. Lithium batteries and lithium-ion batteries are secondary power sources that can be recharged repeatedly, but lithium batteries do not charge well, so they are generally not used as rechargeable batteries.

Lithium-ion batteries (li-ion) are developed from lithium batteries. So before introducing Li-ion, let's introduce lithium batteries. For example, in the past, button batteries used in cameras were lithium batteries.

The cathode material of lithium batteries is manganese dioxide or thionyl chloride, and the negative electrode is lithium. After the battery is assembled, the battery has voltage and does not need to be charged. This kind of battery may also be charged, but the cycle performance is not good, in the process of charging and discharging cycles, it is easy to form lithium dendrites, resulting in a short circuit inside the battery, so under normal circumstances, this kind of battery is forbidden to charge.

Later, Japan's Sony company invented the carbon material as the negative electrode, with lithium-containing compounds as the positive electrode, in the process of charging and discharging, there is no metal lithium, only lithium-ion, which is the lithium-ion battery. When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move through the electrolyte to the negative electrode. The carbon as the negative electrode has a layered structure, it has many micropores, and the lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer, and the more lithium ions are embedded, the higher the charging capacity.

Similarly, when the battery is discharged (i.e., the process in which we use the battery), the lithium ions embedded in the carbon layer of the negative electrode come out and move back to the positive electrode. The more lithium ions that return to the positive electrode, the higher the discharge capacity. When we talk about battery capacity, we usually mean discharge capacity.

During the charging and discharging of li-ion, the lithium ions are in a state of motion from the positive electrode to the negative electrode to the positive electrode. Li-ion is like a rocking chair, the two ends of the rocking chair are the poles of the battery, and the lithium-ion runs back and forth in the rocking chair like an athlete. That's why li-ion is also called a rocking chair battery.

The batteries commonly used in watches are silver batteries. It is often referred to as a coin cell battery. It is characterized by stable voltage and long service life, and can generally be used for more than 2 years.

Lithium batteries are often used in high-tech electronic products. For example: commonly used mobile phones, laptops, some ***, mp4, etc. Lithium batteries are characterized by large capacity, stable voltage, and low pollution.

Watches generally use button batteries.

Lithium batteries are generally used in mobile phones or digital products such as ***, which can be charged and used repeatedly.

Made of lithium composites.

The one used in the watch is not necessarily a lithium battery, and there are other batteries in the shape of a garden cake.

The kind of watch common is not!

In general, there is no problem. Because one is low voltage, the other is that water can only pass AC but not DC, so it cannot produce a large current, as long as the battery sealing part is not damaged, wipe the outside water dry.

The battery is washed in the pocket, there must be a problem, the main thing is that the battery will be short-circuited and scrapped, but it has little impact on people's health, unless the battery is on the spot and causes clothes to be dirty, there will be no long-term impact on people's health.

This will not have any problems, if this is a problem, then the battery will become a dangerous product, rest assured, the voltage of the lithium battery, there will not be much discharge current in the water, are you worried that the chemicals in it will precipitate out because of soaking in water,

Take it out and play with it, bask in the sun, and wait for it to dry and change the electron OK

It's okay, the harm to health is very small, almost negligible, don't worry, the clothes should be worn, the quilt should be covered, and you can just continue to live your happy life.

Lithium-ion batteries do not contain harmful metals such as cadmium, lead, and mercury, so if you don't feel at ease, wash them more often. It's okay.

"Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution. In 1912, lithium metal batteries were first developed by Gilbert NLewis proposed and studied.

In the 70s of the 20th century, m s.Whittingham proposed and began research on lithium-ion batteries.

Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been applied for a long time. With the development of science and technology, lithium batteries have now become the mainstream.

Lithium batteries can be broadly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain lithium in a metallic state and are rechargeable.

The fifth-generation product of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance** ratio are better than those of lithium-ion batteries. Due to its own high technical requirements, only a few companies in a few countries are now producing such lithium metal batteries.

The battery specifications are different for different styles and sizes of watches, as long as you open the back cover, you can see what model it is.

Watch style-sized batteries.

The lithium battery should be installed in the watch, even if it is outside, it can be taken on the plane.

1. Mechanical automatic meter, artificial kinetic energy meter.

The rotation of the rotor in the case is used to drive the electrical energy, and the energy is stored by IC control. It is necessary to use the usual wrist movements to maintain energy production.

Feature: Exercise is energy. No battery replacement is required. Eternal power!

Electricity is driven by the rotation of the rotor in the case, and the energy is stored by IC control. Similar to an automatic watch, it is also necessary to use the normal movement of the wrist to maintain energy production. In addition, when not worn for a long time, in order to save energy, the watch itself will automatically stop the movement of the hands, and at the same time remember the operation of the time.

When the wrist is worn again and the energy is generated, all hands will immediately rotate to the current time when they are worn and continue to run. And you never need to install a battery.

Another explanation might be simpler: the watch has a bead-like thing inside, a hammer, a semicircular piece of metal that sits above the movement, with the center of the movement as its axis, and because the arm is in constant motion, the winding piece of metal automatically rotates due to the gravitational pull of the earth, thus winding the mechanical watch.

2.Eco-Drive watches.

Needless to say, it is also the eternal energy source, solar energy.

The secret of this type of watch is that the watch is thermally insulated except for the back cover, and the temperature of the watch surface is lower than the body temperature, so that there is a temperature difference between the surface and the back cover, and electrical energy can be emitted by the action of a miniature thermocouple. The greater the temperature difference, the greater the heat flow, i.e. the greater the current, so the greater the amount of electrical energy generated. With a difference of 1 degree Celsius, the current generated is enough to make the watch move, and the excess energy generated can flow into a silver-cadmium battery for storage.

If the temperature difference exceeds the capacity to produce energy and the needs of the watch and battery, then a limiting circuit in the watch will direct excess heat energy to the case. Heat can only produce an electric current if it flows in the above direction. If the temperature is the same as the temperature of the wrist, the heat does not flow from the back of the watch to the front through the thermocouple, and no electricity is generated, and if this is the case, or when the watch is not in use, the energy stored in the battery can keep the watch moving.

It is said that a charged battery can make the watch move for more than a year without body temperature.

Like this cheap plastic electronic watch, the battery is generally a battery, as long as the battery voltage size meets the installation conditions, the battery of any material can be used, but the batteries on the market are basically alkaline batteries, and they are replaced once a year to a year and a half under normal use.

Watch battery ???

How can it be???

Dude above, you use a 2032 battery as a watch battery???

Don't mislead.

The computer motherboard uses a CR2032 battery, which generally does not need to be replaced, and can be bought at the small store at the entrance of the school, indicating that it is 2032.

The electronic dictionary used by students is the one used in 2032.

Of course, you can also buy it in the computer city.

Same! Watch batteries are also available, but they have to be ***!

Battery model: CR2032, available in computer stores.

As long as it's 3V, it's the same size, and it's sold in the computer city.

The Beidou Land Destruction Satellite Watch uses a charged lithium battery, which is more unique in that the watch is charged with a small clip early nuclear charger, and it can be used for at least 90 days on a single charge.

The Little Genius** watch is a lithium battery, and it takes about 3 hours to fully charge. It is recommended that you disconnect the watch from the charger in time when it is fully charged, so as to avoid charging for too long and affecting the battery life.
