Introduction Can lithium batteries be recharged at any time? Lithium batteries have no memory effect and can be charged at any time. In order to reduce the number of charges, deliberately depleting the battery and then recharging it will not extend battery life. oppos

Can lithium batteries be recharged at any time?

Lithium batteries have no memory effect and can be charged at any time. Deliberately using the battery and then recharging it to full capacity to reduce the number of charges will not extend battery life. but will have a negative impact on battery life.

In fact, when charging lithium batteries, it is important to “eat less and eat more”. Frequent superficial charging and discharging will help extend their lifespan.

You can charge your phone at any time. You don't need to wait for the low battery alarm or for the phone to be completely discharged. Additionally, when you charge your mobile phone, you should keep the phone in sleep state with black screen and try not to watch videos or play games. When you need to use your mobile phone to talk, it is best to unplug the socketrment. otherwise it will also affect battery life.

Notes:

First of all, keeping lithium-ion batteries properly charged and discharged can extend battery life. Keeping the lithium-ion battery power between 10% and 90% is beneficial to protect the battery. This means that when charging batteries of digital products such as mobile phones and laptops, it is not necessary to reach the maximum value.

If digital products equipped with lithium-ion batteries are exposed to sunlight or stored in hot cars, it is best to keep these products turned off because if the operating temperature exceeds 60 degrees Celsius, the lithium battery -ion ​​will accelerate aging. Lithium battery charging temperature range: 0 ~ 45 degrees Celsius, lithium battery discharge temperature range 0 ~ 60 degrees Celsius.

Second, if the mobile phone battery needs to be charged every day, the reason may be that the battery is defective or it is time to "retire".

For laptop owners, it is best to remove the battery if it is plugged in for a long time (the high heat generated by the computer while in use is not good for the battery of the laptop).

Third, under normal circumstances, 50% power is most conducive to the preservation of lithium-ion batteries.

Different materials

< p > 1. Lithium battery: It is a battery that uses manganese dioxide as the positive electrode material, lithium metal battery metal as the negative electrode material, and uses non-electrolytic solutionwatery.

2. Dry Battery: This is a voltaic battery that uses some absorbent (like sawdust or gelatin) to turn the contents into a paste that will not spread.

2. Different principles

1. Lithium battery: It adopts a spiral winding structure and uses a very thin and highly permeable polyethylene film. is spaced between the positive and negative electrodes.

2. Dry battery: the carbon rod is used as the positive electrode and the zinc cylinder is used as the negative electrode, which converts chemical energy into electrical energy and supplies it to the external circuit. In chemical reactions, because zinc is more active than manganese, zinc loses electrons and becomes oxidized, while manganese gains electrons and is reduced.

3. Different uses

1. Lithium batteries: widely used in mobi phoneslaptops, power tools, electric vehicles, emergency power supplies for public lighting, and navigation lights, small household appliances.

2. Dry batteries: suitable for flashlights, solid-state radios, tape recorders, cameras, electronic clocks, toys, etc., and also suitable for various fields of national economy such as national defense, scientific research, telecommunications, navigation. , aviation and medicine

Known requirements: 50W LED light, lights up for 5 hours a day, keep three rainy weather;

First estimate the capacity of energy storage battery:

The capacity of the battery should be at least 50*5*3=750WH, whether it is a lithium battery or a lead acid battery;

Re-estimate the power of the solar panel:

Suppose there is one sunny day before three rainy days. The battery must be fully charged for. the day. Taking ten hours of sunshine, the solar panel power should be at least 750/10=75W;

More situations can be assumed, and the above method is for reference.
