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. 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.
4. Shape can be customized. Polymer lithium battery models and capacities are available,it has strong applicability.
5. No memory effect. It can be charged and discharged at any time.
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.
The Development of Lithium-ion Battery
The Lithium-ion Battery is a rechargeable battery that relies on the movement of lithium ions between positive and negative poles to complete the charging and discharging work. When the battery is charged, the lithium ions generated on the anode are moved to the negative electrode through the electrolyte, and the more lithium ions are embedded into the negative carbon layer, the higher the battery capacity is. Similarly, when the battery is discharged, the lithium ions in the negative carbon layer move to the positive pole, and the more lithium ions in the anode, the higher the discharge capacity.
Commonly called Lithium Batteries are commonly used as lithium ion batteries, such as mobile phones and notebook computers. Lithium batteries are easily confused with lithium-ion batteries. It main difference is that they are using different materials, lithium batteries based on lithium metal anode, because real lithium batteries because of the risk is bigger, so rarely used daily life products. The positive material of the lithium battery is manganese dioxide or azuride, and the negative is lithium. It's easy to form lithium crystals in the cycle of charging and discharge, causing a short-circuit in the battery, and the battery is charged when the battery is finished and the battery is charged. Such a battery can also be charged, but the cycle performance is not good, and the early lithium battery is generally not charged.
Performance Curves of Lithium Cell:
1.Lithium Cell Charge Curve (Charge at 1C)
2. Lithium Cell Discharge Curve (Discharge at 1C )
3. Lithium Cell Cycle Life Curve
