Lithium battery protection circuit works

The use of lithium recognized safety and efficiency, making it even higher price, sales are still growing rapidly. However, poor quality lithium batteries, such as lithium secondary recovery, fake lithium battery, protection circuit is usually modified or omitted, the occurrence of a short circuit, leakage, or explosion of cases often heard, and therefore recognize lithium real "protection circuit" is every digital mobile phone users the necessary knowledge, after all, superior quality, with lithium battery protection circuit to the patriarch with the phone around.

How to fix lithium battery

Lithium battery applications has been very popular now, how can save costs, so that "dead" lithium battery back to life, and to share what I came to experience
Lithium generally divided into three cases of suspended animation
First, the battery is simply recharged into electricity, chargers, appliances are not recognized, there is no voltage electrode.
Second. Can charge, charger, electrical appliances can identify, but only adhere to a few minutes and runs out quickly.
Third, they can charge, and the capacity is still relatively plentiful, but the large current discharge voltage drops significantly (specific performance such as: Using the camera's shooting mode can only insist on a few minutes, and go back to look at the pattern can persist for a long time)

Polymer lithium battery introduced

Polymer lithium-ion battery is the highest-tech battery industry, the latest varieties to lithium cobalt oxide cathode material, carbon material as the anode, electrolyte or gel state with solid organic conductive film composition, and the use of plastic film for outer packing The latest generation of rechargeable lithium-ion battery.

Lithium battery charging method

The current three-stage battery charger charging method is often used (linear charging mode), ie pretreatment, constant current charging, constant voltage charging. If the battery voltage is below the undervoltage threshold, first enter the preprocessing stage (with a trickle charge mode to charge the battery), if the battery terminal voltage is above the undervoltage threshold, direct normal constant - constant voltage charging way.

Parameter Description Lithium

Many businesses in order to stimulate consumer desire to buy, usually in the form of an oral commitment to consumers: their cell phone battery standby time of up to a month, but the actual use mostly barely hold half a month, used a few times even after a few days no electricity.

Digital Camera Battery Care and Maintenance

Digital camera on battery power, but if you are using a battery does not match or do not pay attention to saving, the battery will run out you do not have to take a few shots. Of course, the battery will eventually run out, when you find that they are depleted, you'll need to replace them.

Lithium battery safety performance test method

Lithium is the lightest non-gaseous in nature metallic substance, its intrinsic potential than any other metals are low compared with other types of batteries, lithium batteries, the ratio of capacity (capacity) of the unit weight and bulk density (unitvolume capacity) are the highest, have an unparalleled advantage.
In addition, the high internal resistance of the lithium battery, because of its internal electrolyte is a colloid aqueous solution instead. In addition, the very low moisture content, stable physical and chemical properties of the electrode material lithium battery can work safely in a wide temperature range. The individual lithium batteries can work in a low-temperature environment of -55 ℃ and 150 ℃ degrees Celsius temperature. Lithium battery rated output voltage of 2.7-3.6V

The cause of the lithium battery life shortened

In real life, lithium batteries commonly found in digital electronic products; often whether it is aware in the process of using the battery, the battery life is far less than the theoretical life.The reason is also controversial.Then the battery should be how to properly use it?Let us continue to find out.

Reasons: internal lithium battery lithium battery life is shortened factors:
1, the side reaction of the lithium-ion battery;
2, a lithium ion battery active substance irreversible consumption;
Large lithium-ion battery, battery current, heat slowly, easy to damage the battery structure;
4, if the additional security measures on the lithium battery, lithium battery provides power to maintain;

Teach you how to buy lithium battery

The lithium battery is divided into lithium-ion batteries and lithium polymer battery. Lithium-ion battery electrolyte flowing solid polymer lithium battery electrolyte, lithium-ion battery is more volatile than the lithium polymer battery, hit the external blows, or does not meet the standard charger, may cause the battery to explode. The batteries are lithium batteries use a lot of mobile phones, laptops, digital cameras and other portable electronic products. Buy poor quality lithium battery, just like in his side put a "time bomb". Therefore, consumers in the purchase of lithium battery must pay attention to the following points:
