We are now talking about lithium-ion batteries. Lithium polymer batteries are smaller and lighter than genuine lithium ion batteries and can typically be used for more than three years.
The lifespan of lithium batteries is generally 300 to 500 charge cycles. Assuming that the power provided by a full discharge is 1Q, if the power reduction after each charge cycle is not taken into account, the lithium battery can provide or supplement a total of 300Q to 500Q of power over of its lifespan. From this we know that if you charge 1/2 each time, you can charge it 600-1000 times; if you charge it 1/3 each time, you can charge it 900-1500 times. By analogy, if it is charged randomly, the number of times is uncertain. In short, no matter how you charge it, the total amount of electricity added is 300Q to 500Q, which is constant. PTherefore, we can also understand this: the lifespan of a lithium battery is related to the total charging capacity of the battery, and has nothing to do with the number of charging times. There is little difference in the impact of deep discharge, deep charge and shallow discharge on the life of lithium batteries.
Are cell phone batteries lithium batteries?
Currently, cell phone batteries are all lithium batteries. The main characteristics of lithium batteries are high voltage and high energy density, which means they can store. lots of power and discharges smoothly. There is almost no self-discharge and no memory effect. It can be charged anytime and anywhere. It is a must-have for all current mobile phones.
Under normal conditions of use and without impactseriously, the lifespan set by mobile phone manufacturers should be 5 years. In humid and rainy areas, the lifespan of mobile phones may be affected. The lifespan of cell phone batteries is related to the quality of the battery and the number of charges. Generally, it can be charged at least 500 times.
To charge cell phone lithium batteries, the charger should use regular products, preferably original chargers, and avoid the use of counterfeit products and products of unknown brands and poor quality.
Don't charge your phone to 100% Once your phone's battery reaches 100%, you should stop charging it immediately, let alone charge it continuously overnight. Although the battery automatically turns off the power after being fully charged and does not continue to overcharge, if you do not unplugthe power plug after being fully charged, the battery will remain at full capacity, although it will not cause explosion or fire. this will accelerate battery loss.
Do not wait until the battery is completely exhausted before recharging, because the battery is almost exhausted and will be deeply discharged, causing great damage to the battery, especially when the battery is very low , like like 20% straight to 100% full charge. The consequences of doing such operation frequently will reduce the battery capacity and shorten its lifespan.
The optimal power ratio of lithium batteries is maintained between 65% and 75%, and the suboptimal power ratio is maintained between 45% and 75%. This is the most ideal state and longest battery life. .
Mobile phone batteries are lithium batteries.
The batterieslithium are mainly batteries that use lithium metal or lithium alloy as the negative electrode material and use non-aqueous electrolyte solution. It works primarily by relying on lithium ions moving between the positive and negative electrodes. During the charging and discharging process, Li+Intercalation and deintercalation between the electrodes: During charging, Li+ is deintercalated from the positive electrode and integrated into the negative electrode through the electrolyte. The negative electrode is in a lithium-rich state; the opposite is true during discharge.
Lithium-ion batteries have many advantages such as high energy density, long life, small size, light weight, low self-discharge, no memory effect and no environmental pollution. environment, and have been widely used. in various fields. Currently, cell phone batteries usemainly read lithium-ion polymer batteries.
