2. The battery must be exhausted before it can be recharged?
For lithium batteries, overcharging is not possible, nor is overdischarging. Especially for previous liquid lithium batteries, the damage was more serious. Of course, the cell phone batteries we use now are almost all lithium polymer batteries or other solid-state lithium batteries. Although there are some differences between each type, it is best not to overload or overload.
We just mentioned that once the phone is fully charged, the automatic protection will stop charging and then enter the normal sleep state. At this point, even connecting the charging cable makes no sense. phone going to sleep? We all know that even if the mobile phone is not in use it will consume power in fact it is consumed by standby and background programs.year. This causes the battery to self-discharge. The charger will continue to activate once the battery level is reduced, that is, if you do not disconnect the battery once it is fully charged, it will repeat this process, which is equivalent. to consume battery life.
In addition, excessive discharge is also bad for cell phones. The best way to recharge cell phone batteries is to recharge them whenever necessary. Don't wait for the last 1%. After all, there are some. some external factors that prevent us from charging. For example, in the event of a sudden power outage, the phone will inevitably turn off automatically because it cannot be charged. It's easy to miss some important information and this can also trigger a low charge level. phone power protection design because the battery is too low toAt that time, it will take a long time to charge it before you can turn it on. This measure is The phone is designed to ensure the safety of its own components, so try. do not use it until the battery is exhausted. In fact, the remaining battery amount displayed on the mobile phone itself is based on data obtained by monitoring and calculation. It is not entirely precise and is often only a rough estimate. In fact, the last amount of energy is easily consumed quickly. the data is simply inaccurate. It is always safer to invoice early.
3. At least 90% of people don't know what simple charge and discharge is.
When it comes to battery life, mobile phone manufacturers usually say that battery 500 last 1,000 cycles upon promotion. The effective capacity is greater than XX%. What kind of concept isgit?
Many people don't know what a cycle is. In fact, a cycle is what we call a charge and a discharge. Make no mistake, one charge and one discharge. are not It refers to the process of plugging and unplugging the charging cable all at once, but from 100% to 100% at the same time. That is, when your mobile phone is still 100% powered, it is drained to 0% after full use and then fully charged to 100%. This is a cycle, also called charging and discharging. If I use it at 50% and charge it at 100% each time, it will be one cycle after two times. Real
The reason why some people find their cell phone battery life is not as good as before after a while may be due to various reasons, such as a substantial increase in your actual battery. usage time and application consumption, poorRelatively inferior charging and discharging habits and batteries. Wait, and mobile phone systems tend to become redundant with use, and the background
Why the performance of flexible packaged lithium batteries. begin to decline after more than 2 months of use
The difference lies in the positive and negative aspects of liquid lithium-ion batteries and polymer lithium-ion batteriesThe electrode material and the The electrolyte are made of different materials, one contains liquid and the other does not. Another form of soft bag is called a lithium-ion polymer battery.
Soft-pack lithium battery:
The soft-pack lithium battery is simply a liquid lithium-ion battery with a polymer shell. Structurally, it is packaged in aluminum-plastic film. If there is a safety risk, the soft battery will only swell and crack.
Pol batteryymer:
Lithium polymer battery (Li-polymer, also known as lithium polymer battery): It is also a type of lithium-ion battery, but it is different from liquid battery . Lithium (Li-ion) battery is a new type of battery which has many obvious advantages such as high energy density, smaller size, ultra-thin, light weight and high safety. In terms of shape, lithium polymer batteries are ultra-thin and can be made into batteries of any shape and capacity to meet the needs of various products. The minimum thickness that this type of battery can achieve is up to 0.5 mm. Its rated voltage is the same as Li-ion 3.7V, and there is no memory effect.
The reason why it is prepared as a soft battery is that the lithium battery decomposes to produce gas and bulge during cycling. Y coRegardless of the battery preparation process, etc., this may cause the capacity of your lithium battery to drop significantly after being charged and discharged only a few times. In addition, I would like to give you a suggestion: do not often drive on roads with relatively steep slopes. It doesn't matter if you go down. Then, when charging, try to wait until it's almost empty before charging. In this way, the performance of your lithium battery electric vehicle will be better maintained.
