Product performance:

1. Good safety performance. Built in circuit protection board, with short circuit, overcharge,over discharge, shock, vibration, acupuncture, high temperature,no explosion ,etc.

2. Stable performance. Long cycle life, after 500 times of ontinuous charge and discharge,the battery capacity shall not be less than 80% of the rated capacity.

3. No memory effect. It can be charged and discharged at any time.

4. Small thickness and high volume utilization. Polymer lithium battery overcomes Lithium battery in the thickness of the bottleneck, to achieve ultra-thin settings, and can assemble it into a credit card. Polymer cell can achieve thickness up to less than 1 mm, in line with the current demand for mobile phones.

5. Shape can be customized. Polymer lithium battery models and capacities are available,it has strong applicability.

Application : lighting, backup power supply, wind energy storage, communication equipment, IT products, IC card terminal, GPS system, LED lights, medical equipment,instrumentation, beauty and hair products, electric toys, flashlight, miner's lamp, agricultural machinery equipment, electric tools, etc.

How are Lithium Batteries Protected?

Discharge protection: Over-discharge protection should not occur when used by the client. This over-discharge protection is a post-level protection. Generally speaking, for batteries with a protection voltage of 2.5V, the minimum voltage of the electrical appliances used should be 3.0V Or above, the battery's over-discharge protection voltage cannot be used every time to use the battery correctly.

Charge overcurrent protection: Generally speaking, the protection occurs when the current of the charger is greater than the charge overcurrent protection value of the battery, which belongs to the matching problem between the two.

Discharge overcurrent protection: Generally speaking, the battery protection is caused by the large starting current of the electrical equipment. This should be considered at the beginning of the design for the redundancy of the battery overcurrent, which needs to be provided to the manufacturer of the battery design to avoid overcurrent protection. Occurs; if a rate-type battery needs to provide a rate of continuous discharge current, this current is different from the maximum discharge current of the battery. The maximum discharge current of the battery refers to the discharge at this current, not continuous discharge. Because continuous discharge has a large number of heating problems to be solved, there must be a large redundant design in the design.

Short-circuit protection: If there is a short-circuit protection, you need to find out the reason to avoid repeated short-circuit protection. If accidental short-circuit protection occurs, you need to remove the short-circuit protection before normal assembly and use; if the battery is in contact with the device The short-circuit protection that occurs during the installation process requires the battery to be disassembled, and then assembled again after the short-circuit protection is released; the general method of short-circuit release is to charge.

Lithium Battery Cell Model

Voltage of single cell of lithium battery is 3.7V, but Ni-MH and Ni-Cd is only 1.2V, which means one lithium battery cell could replace three Ni-MH or Ni-Cd cells. Therefore, lithium battery pack has much smaller size than Ni-MH and Ni-Cd battery pack.

Self-discharge rate of lithium battery is 5% per month, which is much lower than Ni-MH and Ni-Cd (25% per month). Lithium battery has around 800 times of cycle life, which is also longer than Ni-MH and Ni-Cd(500 times). So lithium battery is replacing Ni-MH and Ni-Cd in more and more fields.
