Cell phone batteries for the working principle, may be lot of friends want to know, and only know the cell phone battery at the working principle, the U.S. will be able to deeper understanding of their mobile phone, thus avoiding the phenomenon of mobile phone battery explosion happened.

The classification of cell phone batteries

Ni-Cd batteries: composed by two plates, one side is the production of nickel metal, the other side are the production of cadmium metal, so called nickel-cadmium battery only these two metals in the batteries happen reversible reaction, so the battery can recharge your batteries This is also the first generation of mobile phone batteries, to use necessary to safeguard it.

Nickel metal hydride batteries: nickel metal hydride batteries have another name of environmental protection batteries, because it does not contain cadmium metal, will not pollute the environment. Its power reserve than the nickel-cadmium battery 30% to 50% more talk time of mobile phones has also been extended by 30%, but its structure with the nickel-cadmium batteries are basically the same, but different internal materials

Lithium-ion batteries: a high energy density of batteries, it is the same size nickel-cadmium batteries, nickel metal hydride batteries as compared to larger power reserve, is also lighter weight. Lithium-ion batteries based on security considerations, its also built a control chip to provide electricity, voltage, current and so on many aspects of the protection of control, be able to avoid over-charging the battery constitutes a dangerous situation and to further improve the battery the use of security.

Because the former two types of battery are no longer in use, and this principle we will not make its introduction, but everyone in the current lithium-ion batteries used in principle to the introduction.

Lithium batteries contain lithium because it got its name, lithium is a metal element, is a silvery white, very soft, lively and chemical properties of the metal, in metal is the lightest. Lithium-ion battery cathode materials typically have the active compounds of lithium composition, negative electrode is a special molecular structure of carbon. Common cathode materials for major components of LiCoO2, charging, add the electric polarization in the battery cathode potential to force the release of lithium-ion compounds, embedded negative elements were arranged lamellar structure in carbon. Discharge, the lithium ion from the lamellar structure of the carbon in precipitation, and re-cathode combination of compounds, because of lithium-ion mobile resulting current output for cell phone use.

Lithium battery protection circuit circuit

The use of lithium batteries recognized the efficiency and security, makes it even higher prices, sales are still growing rapidly. Lithium battery protection circuit and the circuit is the patron saint of lithium batteries, can effectively work to allow lithium batteries, as well as to protect the control, the so-called lithium-ion battery protection circuit is a circuit while the piece of lithium battery protection circuit.

1, the protection circuit the need to:

Lithium-ion rechargeable battery charging or if there have been over-discharge, and often there will be expansion of the battery, leakage and other abnormal situation, the protection circuit prevents the device itself or charger malfunction, or improper use, the battery appears damaged and deteriorating performance settings . Under normal use conditions, the protection circuit is not working.

2, the protection circuit loop installation location:

Protection circuit with a single battery and battery plate fused, even if the charger or the machine itself, a fault protection circuit can also prevent cell damage, leakage, deterioration characteristics of the role. These protection circuits must be installed in the battery plate by professional firms for different battery design loop.

3, the protection circuit to avoid damage:

Avoid the use of strong electrostatic place batteries, such as certain laboratory, precision instruments near thunderstorms open Office and so on.

4, the battery charging temperature range of security:

The best batteries at 0-45 degrees Celsius between the charge in order to maintain the best safety the most state-of-charge, otherwise easy to damage the protection circuit to reduce the battery life performance. Such as parked in the car under the scorching sun exposure, the battery does not fit one of the placement.

After reading the battery, as well as attention to the working principle of matter, I believe everyone will have lithium batteries deeper understanding.
