Does the cold weather affect the charging of mobile phones?

The charging speed will slow down and the battery will be very durable after being fully charged. This is because the current mobile phone battery is a lithium battery, and the suitable working temperature of the lithium battery is 15-40 degrees, so if the ambient temperature is too low, the lithium battery will automatically reduce the working voltage, so the charging speed of the same charger is much slower in a low temperature environment.

However, when the temperature is low, the lithium battery is not fully discharged, so the battery is not durable in the low temperature environment. In some cases, when the temperature is very low, there will even be power failure for self-protection, so sometimes the phone will automatically turn off when the temperature is low.

New technology of mobile phone charging in cold weather;

Facing the current "mobile phone will automatically turn off in low temperature environment", it is because "in low temperature environment, the chemical reaction speed of the battery is slow, the discharge current is small, and the temperature protection circuit in the battery built-in protection board is started, and the mobile phone will automatically turn off".

Scientists have recently developed a new technology of "cold-resistant hard carbon anode" and "lithium-rich cathode". It is understood that during the first charging process, lithium ions will flow from the positive electrode to the negative electrode, and some lithium ions will be lost, but lithium ions will be embedded and stored. Vanadium phosphate positive electrode with reduced lithium ions and pre-lithiated hard carbon negative electrode will be used.

The battery retains the high energy density, high charge and long service life of the traditional lithium ion battery.

Thanks to the natural characteristics of vanadium phosphate cathode and the rapid reaction kinetics of pre-lithiated hard carbon anode, even at MINUS 40℃, the battery equipped with "cold-resistant hard carbon anode" and "lithium-rich cathode" technology can maintain 2/3 power, while the conventional lithium battery only has 10% power.
