The answer is that it will not freeze, lithium batteries are much less affected by cold weather than other types of batteries, if the lithium battery is placed in freezing temperatures, the battery’s ability to power the device will be significantly reduced or curtailed.

In the freezing ring temperature, will make the electrolyte harden, electrolyte circulation is not smooth, reduce the transmission rate of lithium batteries, the current flow rate will be slowed down, will seriously affect the capacity of the battery. In the low temperature environment will damage the battery, the worst case scenario is also the occurrence of freezing phenomenon.

The effect of cold on lithium batteries

1. Reduce battery capacity and performance

In cold weather, the power consumption capacity of lithium batteries will increase, and the chemical reaction of lithium batteries will be slowed down in a cold environment, resulting in a lower discharge current of lithium batteries, and the capacity of the battery will also decrease. (Note: The chemical reaction of lithium battery is mainly the movement of lithium ions between positive and negative electrodes)

2. Reduce the duration

Lithium batteries in cold weather power consumption capacity will increase, the capacity of the battery will decline, which will lead to reduce the duration of use.

3.Slower charging speed

The charging speed of lithium batteries decreases in cold weather, and the batteries take longer to fully charge.

4. May cause damage to battery components

Under the extremely cold environment, it may affect the components of the battery, such as electrodes, connectors, spacers will be damaged, which will cause the battery to rupture, leakage and so on.

5.Safety

Charging lithium batteries in a low temperature environment, there are certain safety hazards, with the lowering of the temperature, lithium battery graphite anode power characteristics will deteriorate, the electrochemical polarization of the negative electrode in the charging process will be significantly increased, which may lead to the precipitation of lithium metal to form lithium dendrites, which can break through the diaphragm and trigger a short-circuit of the positive and negative electrodes.

How to protect lithium batteries in cold weather

No matter what type of battery we use, cold weather conditions will affect the performance and function of the battery, the chemical reaction of the battery will slow down, which will limit our use of the battery. Therefore we recommend taking the necessary precautions to ensure stable battery operation and prevent the battery from being damaged.

1. Select different types of batteries

Lithium-ion batteries are made in different ways, and the materials used in the batteries will be different, so we can choose a battery that can effectively withstand cold weather according to our needs.

2. Preheat the battery before charging

When charging the battery in cold weather, it is better to preheat the battery, you can use the battery heater and other methods, which can minimize the effect of cold weather on the performance of the battery.

3.Use battery blanket

Battery blankets are thermal blankets that are used to keep batteries warm in cold weather by trapping heat from the battery, providing warmth to the battery and addressing the effects of low temperatures on the environment. They are designed to fit snugly against the battery to prevent the battery from being exposed to cold temperatures.

4. Place batteries in battery boxes or insulated storage units

Battery boxes and insulated storage units are compact and reusable devices made from a variety of materials whose main purpose is to protect the battery pack from exposure to cold weather and keep the lithium batteries warm. The insulating material retains the heat generated by the battery and keeps the battery as warm as possible.

5. Store the battery in a warm place

In a warm environment, lithium batteries can work normally, provide stable and reliable power, will not affect the capacity of the battery, reduce the damage caused to the battery.

6. Use a battery heater

Battery heaters are great for insulating lithium batteries and keeping them warm in cold conditions. At the same time, the battery heater can also regulate the temperature and settings to ensure that the lithium battery can be in good working condition, will not reduce the life of the battery.

7. Regular battery maintenance

In cold weather, you can check the appearance of lithium batteries, check the environmental status of lithium batteries, check the state of lithium battery power, to ensure that the lithium battery is running well, in the cold environment to reduce the damage to the battery.

Conclusion:

Lithium batteries do not freeze, in the cold weather will affect the capacity and performance of lithium batteries, the battery will reduce the use of time, charging time will become longer, serious safety problems will occur. We can use different types of batteries, or battery maintenance, use a battery heater and other methods to make the battery run well in the cold environment.
