New green battery is in recent years has been put into use or is developing a class of high-performance, pollution-free batteries. Lithium Ion Power Bank, metal hydride nickel batteries and nickel-free alkaline zinc-manganese batteries that are being used and lithium Lithium Ion Power Bank, fuel cells, and electrochemical storage supercapacitors that are being developed are all new Green battery category. In addition, has been widely used in the use of solar energy photoelectric conversion of solar cells (also known as photovoltaic power generation), also belong to this category.
Lithium Ion Power Bank works is the principle of its charge and discharge. When the battery is charged, the battery has a positive lithium ion generation, the generated lithium ions through the electrolyte movement to the negative. And the negative carbon as a layered structure, it has a lot of holes, to reach the negative lithium ions embedded in the carbon layer of the pores, the more lithium ions embedded, the higher the charge capacity.
In order to ensure the safety of Lithium Ion Power Bank, we Amy's electronic engineers are often tested several times, the test results
1. Various environmental abuse test: the abuse of the test, such as external short circuit, overcharge, acupuncture, flat impact, burning, etc., to check the safety performance of the battery. At the same time the battery temperature test and vibration, drop, impact and other mechanical properties test, the battery in the actual use of the environment under the performance of the situation.
2. Add additives to the electro-hydraulic: the battery overcharge, the battery voltage is higher than 4.2v under the conditions of electro-hydraulic additives and other substances in the electro-polymerization polymerization, battery resistance increased, the battery inside the formation of a large area of open circuit, battery No longer warming up.
3. Lithium Ion Power Bank charging is divided into two stages: the first constant current charging, to close to the termination voltage to constant voltage charging, such as a 800mAh capacity lithium battery, the termination of the charging voltage of 4.2V. Battery to 160mA (charge rate Is 0.2C) constant current charging, the battery voltage at the beginning of a large slope of the boost, when the battery voltage close to 4.2V, become 4.2V constant voltage charging, the current gradually, the voltage change is not, to the charge current down to 0.01C (about 8mA), that is close to full, you can terminate the charge.
Lithium Ion Power Bank use precautions
1, do not disassemble the battery, do not heat the battery.
2, a one-time battery regeneration can not be heated or charged, otherwise there may be an explosion.
3, electrical and battery contacts should be clean, if necessary, wipe with a damp cloth, to be dry after the polarity marked correctly loaded. When installing batteries, it is important to install polar ("+" and "-") installations that should be installed using the recommended battery in accordance with the instructions of the appliance. Failure to follow the instructions will result in malfunction of the appliance, damage to the appliance and / or battery. Such as 3 or 3 batteries in series, one of the polar anti-reverse, the reverse battery is charged, the internal gas, leakage and electrolyte leakage, and some batteries are likely to explode, people have hurt.
4, the old and new batteries do not mix, but the same type but different types of electrochemical or grade batteries do not mix, or will make a group of batteries in the use of some batteries in the over-discharge state, thereby increasing the possibility of leakage.
5, can not short circuit the battery, so as to avoid leakage of the battery or heat damage to the insulation packaging.
6, electrical appliances should not be used for a long time when the battery should be removed after use, so that the battery continues to discharge to the internal adverse chemical reactions caused by leakage.
7, waste batteries do not arbitrarily discarded, as far as possible with other garbage separately.
