The difference between polymer lithium battery and lithium battery

<p>Polymer<a href="https://www.hgbbattery.com/product" rel="noopener noreferrer" target="_blank"> <a href="https://www.hgbbattery.com/product" target="_blank">lithium batteries</a></a> generally refer to polymer lithium ion batteries. According to the different electrolyte materials used in lithium ion batteries, lithium ion batteries are divided into liquid lithium ion batteries and polymer lithium ion batteries or plastic lithium ion batteries. Do you know the difference between polymer lithium battery and lithium battery?</p><p><br></p><p><br></p><p>1. The difference between polymer lithium battery and lithium battery</p><p><br></p><p><br></p><p>Compared with lithium ion batteries, the characteristics of lithium polymer batteries are as follows:</p><p><br></p><p><br></p><p>1. There is no battery leakage problem. The battery does not contain liquid electrolyte and uses colloidal solids.</p><p><br></p><p><br></p><p>2. Can be made into a thin battery: with a capacity of 3.6V400mAh, its thickness can be as thin as 0.5mm.</p><p><br></p><p><br></p><p>3. The battery can be designed into various shapes.</p><p><br></p><p><br></p><p>4. The battery can be bent and deformed: the polymer battery can be bent about 900.</p><p><br></p><p><br></p><p>5. Can be made into a single high-voltage battery: liquid electrolyte batteries can only be connected in series to obtain high-voltage, polymer batteries.</p><p><br></p><p><br></p><p>6. Since there is no liquid, it can be made into a multi-layer combination in a single particle to achieve high voltage.</p><p><br></p><p><br></p><p>7. The capacity will be twice as high as a lithium-ion battery of the same size.</p><p><br></p><p><br></p><p><br></p><p>2. Life of polymer lithium battery</p><p><br></p><p><br></p><p><br></p><p>The correct statement: Lithium battery life is related to the number of completions of the charging cycle, not directly related to the number of charging cycles.</p><p><br></p><p>Simple understanding, for example, a lithium battery used only half of its power on the first day, and then it was fully charged. If it is still the case the next day, that is, use half of the charge and charge it twice. This can only be counted as one charging cycle, not two. Therefore, it may usually take several times to complete a cycle. Every time a charging cycle is completed, the power will decrease a bit. However, the reduction is very small. High-quality batteries will still retain 80% of the original power after being charged for multiple cycles. Many lithium-powered products are still used as usual after two or three years. This is the reason. Of course, the life of the lithium battery needs to be replaced.</p><p><br></p><p><br></p><p>The life of a lithium battery is generally 300 to 500 charging cycles. Assuming that the power provided by a complete discharge is Q, if the reduction in power after each charging cycle is not considered, the lithium battery can provide or supplement 300Q-500Q of power in its life. From this we know that if you charge 1/2 each time, you can charge 600-1000 times; if you charge 1/3 each time, you can charge 900-1500 times. By analogy, if it is charged randomly, the number of times is variable. In short, no matter how it is charged, the total power of 300Q～500Q is constant. Therefore, we can also understand this: the life of a lithium battery is related to the total charge capacity of the battery, and has nothing to do with the number of charges. Deep discharge and deep charge and shallow discharge and shallow charge have little difference in the impact of lithium battery life.</p><p><br></p><p><br></p><p>In fact, shallow charging and shallow charging are more beneficial to lithium batteries. Only when the product's power module is calibrated for<a href="https://www.hgbbattery.com/product" rel="noopener noreferrer" target="_blank"> lithium batteries</a>, is it necessary to deep discharge and deep charge. Therefore, products powered by lithium batteries do not need to be constrained by the process. Everything is convenient and can be charged at any time without worrying about affecting life.</p><p><br></p><p><br></p><p>If the lithium battery is used in an environment above the specified operating temperature, that is, 35°C or higher, the power of the battery will continue to decrease, that is, the battery's power supply time will not be as long as usual. If the device is charged at such a temperature, the damage to the battery will be even greater. Even if the battery is stored in a hot environment, it will inevitably cause corresponding damage to the quality of the battery. Therefore, keeping the operating temperature as suitable as possible is a good way to extend the life of the lithium battery.</p><p><br></p><p><br></p><p>If you use the lithium battery in a low temperature environment, that is, below 4°C, you will also find that the battery life is reduced. The original lithium battery of some mobile phones cannot even be charged in a low temperature environment. But don't worry too much. This is only a temporary situation, which is different from the use in a high-temperature environment. Once the temperature rises, the molecules in the battery are heated, and they will immediately return to the previous power.</p><p><br></p><p>To give full play to the effectiveness of lithium-ion batteries, you need to use it frequently to keep the electrons in the lithium battery in a flowing state. If you don't use the lithium battery often, please remember to complete a charging cycle for the lithium battery every month and do a power calibration, that is, deep discharge and deep charge once.</p>
