For mobile phone battery principle of work, perhaps many friends want to know, only by understanding the handset battery principle of work, everybody can understand oneself one step further, to avoid the mobile phone battery explosion of the phenomenon.
The classification of battery
Nickel cadmium battery: consists of two side is composed, plate making, nickel metal is the other side of the metal cadmium, so called nickel cadmium battery this two kinds of metal in the battery in reversible response, so battery recharging, this also is the first generation of mobile phone battery, use rise need maintenance.
Nickel cadmium battery: nickel cadmium battery has another name battery, because it does not contain cadmium metal, not pollute the environment. It’s power reserve ratio nickel cadmium battery more than 30% to 50%, mobile phone calls and prolong the time and so on, but the 30% with nickel cadmium battery, but differ in internal materials
Nickel cadmium battery: is a kind of high energy density of the battery, and the same size of the nickel cadmium battery, compared to nickel cadmium battery power reserves bigger and more light weight. Based on the safety of nickel cadmium in batteries, it also has a built-in control chip, to provide power, voltage, current, many aspects of protection, can avoid to control charging battery constitute the excessive caused dangerous phenomenon, and further improve the safety of using battery.
Because the two kinds of battery has not put into use, we will not only introduces the principle, for everyone in the use of nickel cadmium battery principle are introduced.
Nickel cadmium in batteries for lithium ofits, lithium is a kind of metal elements, is a silvery white, soft and chemical properties are very lively in the metal, metal is the lightest. Nickel cadmium battery anode materials are usually the active compounds, lithium anode is special molecular structure of carbon. Common battery anode materials for the main component LiCoO2, charging the battery, and the potential of the positive force between compounds, lithium ion release molecules across embedded in the structure of carbon. Discharge, lithium ion from slice layer structure of carbon compounds, and positive, because of lithium ion movement and thus output current for mobile phone use.
Nickel cadmium battery protective circuit circuit
Nickel cadmium battery recognized use efficiency and security, and makes it even higher prices, sales still grow rapidly. And nickel cadmium battery protective circuit circuit is the patron saint of nickel cadmium battery, can effective let nickel cadmium battery for work on the protection and control, and the so-called nickel cadmium battery protective circuit circuit is the nickel cadmium battery is the protection circuit.
1 and the necessity of protection circuit:
Li-ion rechargeable battery charging or if there is often happen.according to discharge battery inflation, leakage protection circuit abnormal phenomenon, can prevent itself or malfunction with the charger, or because of improper use, battery failure and the performance deterioration and Settings. In normal conditions, the protection circuit is not working.
2, the protection circuit circuit of the installation position:
Protection circuit with a single battery and panel is a machine itself, even if the charger or fault, protect circuit can prevent cell damage, discharge, characteristics of degradation. These protect circuit must be put in the panels, and the professional company according to different battery design circuits.
3 and avoid protection circuit damage:
Avoid the use of static in places such as batteries, laboratory, precision instruments, empty place near the thunderstorm, etc.
4 and the battery safe charge temperature range:
The battery is best in between 45 degrees centigrade 0 – to maintain optimum charging, the safety of charging protection circuit, otherwise easy damage and reduce battery performance life. For the strong sunlight parked in the car, the battery is not suitable for placement.
Nickel cadmium battery internal structure and work principle
nicd battery
Nickel cadmium battery is composed of two plates, one is using nickel, another is the cadmium in batteries two metal occurs reversible reaction, battery recharging. Nickel cadmium is characteristic of “firm”, cheap price. Defect is for environmental pollution metal cadmium battery capacity, small, short life, so the battery is nickel cadmium battery, cheap, and every memory effects are charging and discharging charge shall be first.The battery is nickel cadmium battery replacement products, relative to the nickel cadmium battery, it is all the more remarkable nimh batteries. It greatly reduces the nickel cadmium in batteries “memory effects”, which makes use of nimh batteries more convenience, more long use life cycle (up to 1,000 times). In addition, still have the capacity nimh batteries, discharge, high resistance to overcharge depth and discharge, charging time short obvious advantages. The most important is no longer used nimh batteries toxic metal material, can eliminate the as pollution to the environment. At the same time, in the electrical characteristics and nickel cadmium battery basic similar, in actual applications can completely replace the nickel cadmium battery without the need for any modification of the camera? / P >
Of course, also not perfect nimh batteries, it also exist some disadvantages. It is poorer, high temperature characteristics in 45 degrees Celsius above and below 0 degrees under the environment of the cryogenic environment, will not work properly nimh batteries, even cannot start the camera, In addition, the battery is relatively high self-discharge, storage after period of time will find it’s power decrease, There is a nimh batteries exist mild memory effects.
