Will charging your phone in cold weather affect it?

The charging speed will be slower and once fully charged, the battery will not be durable at all. This is because current mobile phone batteries are lithium batteries, and the suitable operating temperature of lithium batteries is 15-40°C. degrees, so if the ambient temperature is too low, the lithium battery will automatically reduce the operating voltage, so the same charger will charge much slower in a low temperature environment.

When the temperature is low, the power of the lithium battery is not fully released, so the battery is not durable in low temperature environments. In some cases, when the temperature is very low, self-protection can even. happen when the temperature is very low, so sometimes when the temperature is low, the phone turns off automatically.

New technology for charging mobile phones in cold weather:

In the face of today's "low temperature environment" The reason why the phone automatically turns off when it is unplugged is because "in a low temperature environment, the chemical reaction speed of the battery slows down, the discharge current becomes smaller, and the temperature protection circuit of the battery built-in protection board is activated and the phone will turn off automatically.

Scientists have recently developed a new technology of "cold-resistant hard carbon anode" and "lithium-rich cathode". This "cold-resistant hard carbon anode" and "lithium-rich cathode" technology, in the first charging process, theLithium ions flow from the cathode to the anode and some lithium ions will be lost, but the lithium ions will be integrated and stored using a lithium ion reduced vanadium phosphate cathode with a pre-lithiated hard carbon anode.

The battery retains the high energy density, high power capacity and cycle life of conventional lithium-ion batteries.

Thanks to the natural characteristics of the vanadium phosphate cathode and the rapid reaction kinetics of the pre-lithiated hard carbon anode, even at minus 40°C, it is equipped with a " cold-resistant hard carbon anode". and “lithium-rich cathode” technologies. The battery power can also be maintained at 2/3, while the energy retention capacity of conventional lithium batteries is only 10%.

My lithium battery can't work at minus 20 degrees in winter. Far, can it return to normal in summer?

It depends on the temperature in winter and personal usage habits, but under normal circumstances, it will decrease. around 10%.

Lithium batteries can generally be charged and discharged 300 to 500 times. It is better for lithium batteries to be partially discharged rather than fully discharged, and try to avoid frequent full discharges. Once the battery is disconnected, the clock begins to move.

Whether used or not, the lifespan of lithium batteries is only a few years. The decrease in battery capacity is due to an increase in internal resistance caused by oxidation (which is the main cause of the decrease in battery capacity). Finally, the resistanceBattery capacity will reach a certain point. Although the battery is fully charged at this time, it cannot release the stored energy.

If possibleIf possible, charge the battery to 40% and store it in a cool place. In this way, the battery protection circuit can work for a long time. If the battery is placed in high temperature after being fully charged, it will cause serious damage to the battery.

Therefore, when using a fixed power supply, the battery is in a fully charged state and the temperature is generally between 25-30°C, which will damage the battery and cause its capacity to decrease .

Notes on extending the capacity and life of lithium batteries;

1. If you use an external power supply. power your laptop for a long time. If the computerpower is on or if the battery charge has exceeded 80%, remove the battery immediately. There is no need to fully charge the battery during normal charging, just charge it to around 80%. Adjust the operating system power options and set the power alarm above 20%. The minimum battery power should not be less than 20%.

2. For mobile phones and other small electronic devices, the power cord (including the USB interface for charging function) should be unplugged immediately after charging. Keeping it connected will damage the battery. Charge frequently, but it is not necessary to fully charge the battery.

3. Whether it's a laptop or mobile phone, be careful not to let the battery run out (automatic shutdown).

4. If you want to travel, you can fully charge the battery, but chaSwitch off electrical appliances at any time if conditions permit.

5. Use a smarter, more energy-efficient operating system.

To what extent does the lithium battery of electric vehicles decompose in winter?

It can be restored. It is normal for the temperature to drop and the battery storage capacity to decrease. It has nothing to do with battery quality. Users should not blindly replace the battery. .

As the temperature drops, the activity of various substances present in the battery will decrease and the energy storage capacity will also deteriorate. When the temperature is around 25°C, the battery can store electricity normally and discharge to the maximum; when the temperature drops below 10°C, the quantity of electricityé stored in the battery will be reduced by 20%. When the temperature is below 0℃, the stored power will be reduced by 30% or more. Therefore, even if it is a newly purchased electric vehicle, there will be problems with low battery life in winter.

Determined according to winter temperature and personal usage habits, but under normal circumstances it will decrease by about 10%.

Lithium batteries can generally be charged and discharged 300 to 500 times. It is better for lithium batteries to be partially discharged rather than fully discharged, and try to avoid frequent full discharges. Once the battery is disconnected, the clock begins to move.
