Why batteries die in cold temperatures is an interesting yet annoying question. One of the most important variables affecting a battery’s performance is temperature.
The capacity and discharge rate of the battery decline as the temperature drops because the chemical reactions needed to produce energy become slower and less effective. Furthermore, the battery loses some of its mechanical stability, and charging may result in additional harm.
Discover the five techniques to keep batteries warm in the winter and why cold weather is so bad for battery life in this blog post.

Why Does a Battery Die in Cold Weather?
Battery cells are typically tested to withstand a wide range of temperatures because they are susceptible to environmental factors. However, a large change in temperature might seriously harm your batteries. However, why do batteries degrade in cold weather?
The chemical reactions needed to produce energy slow down and become less effective as the temperature drops. The battery’s capacity and discharge rate deteriorate as a result of this ongoing stress. Furthermore, the battery’s mechanical stability deteriorates, increasing the likelihood of an unexpected failure.
Additionally, the chemical reactions may be further hampered if a battery is charged in cold conditions. Reversible reduction reactions power battery cells like lithium-ion batteries, and rapid plating—the deposition of lithium ions on the anode without intercalation into the carbon sites—occurs when the temperature lowers considerably. This could puncture the cell’s separator and result in a short circuit that drains the battery.
How Do Lithium-Ion Batteries React to Cold Weather?
Have you ever had to call off a road trip or an outdoor project because the chilly weather caused your lithium-ion batteries to die too soon? Despite their reputation as one of the greatest batteries for cold climates, lithium-ion batteries suffer greatly from cold temperatures, which can drastically lower their performance and efficiency.
When lithium ions move from the graphite anode (negative electrode) to the cathode (positive electrode), an electric current is released from the battery. In cold weather, this process slows down, which reduces their power. Lithium ions will simply coat the anode (lithium plating) when the temperature drops, increasing the electrolyte’s resistance and reducing the number of lithium ions available to generate the electrical current. Although lithium-ion batteries should ideally run at 98–95% of their rated capacity, this can lower the battery’s capacity by 20%–30%.
In summary, lithium batteries can suffer serious drawbacks if they are not used, charged, and kept in accordance with cold weather standards, even if they still retain the majority of their performance in cold weather and are likely still the best batteries in cold weather. When organizing any project, road trip, etc. in cold weather, it is crucial to take these adverse effects of lithium batteries into account.
Knowing How Chemicals React at Low Temperatures
As previously stated, the conductivity of the electrolyte in the battery and the rate at which lithium ions intercalate at the graphite electrode both decrease with decreasing temperatures.
Ion insertion and ion adsorption are the two stages of the intercalation reaction. The transfer of lithium ions from the cathode surface into the graphite carbon sites is known as ion insertion. The assimilation of lithium ions on the carbon mesh surface is known as ion adsorption. As the temperature drops, so does the activation energy for intercalation, which in turn slows down the rate of lithium insertion and adsorption.
The process by which lithium ions create a long trench of alloy at the cathode surface, lowering the quantity of lithium ions that can be inserted into the carbon sites, is known as the lithium plating reaction. The alloy forms more readily at lower temperatures, which speeds up the plating process. This plating slows down the rate of intercalation in addition to lowering the number of lithium ions accessible for intercalation.

It is evident from the information above that a lithium-ion battery’s performance is hampered by low temperatures.
Can Batteries Made of Lithium Freeze?
The question, “Do lithium batteries freeze?” is frequently asked. In actuality, the answer would have to be no if you were to understand the word “freeze” literally. However, it can significantly hinder and decrease the battery’s ability to power gadgets in subfreezing temperatures.
Low temperatures cause a sharp decline in the rate of lithium-ion transport into and out of the anode of lithium batteries. The lithium-ion alloy that plates onto the anode’s surface and blocks ion entry into the anode’s carbon site is the reason for this drop in the rate of lithium-ion transfer. Consequently, this stops current flow and significantly lowers battery capacity. Stated differently, if the lithium-ion cannot pass through the anode, the battery “freezes.”
In addition to lowering capacity, freezing conditions have a more detrimental effect on several battery components. For instance, the electrolyte may stiffen and circulate less smoothly, which would slow down the transfer of lithium ions. Voltage and output power of the battery decrease as capacity decreases.
In summary, although a battery cannot be “frozen,” freezing temperatures do have an adverse effect on lithium batteries. Low temperatures will hinder the lithium-ion’s ability to move in and out of the anode and impair the performance of the battery’s constituent parts.
What Is the Adverse Temperature for Lithium Batteries?
If you want to use lithium batteries in equipment that has a wide temperature range, it’s critical to know what temperatures are harmful to them. For best safety, lithium batteries should only be charged between 32°F and 131°F (0°C and 55°C), even though the ideal temperature range for them is -4°F to 140°F. Before charging, make sure the temperature is within the safe limit because higher temperatures can possibly cause an explosion.
What temperature is too low for lithium batteries, then? Unfortunately, batteries can sustain significant damage from any temperature below 32°F. When lithium batteries are charged below the freezing point, the chemical reactions slow down until almost no useable energy is produced. The batteries may finally quit functioning completely at this time.
Lithium batteries should not be charged in temperatures below freezing as this can result in irreversible damage.
Five Fantastic Ways to Keep Lithium Batteries Warm in Cold Weather
When it comes to keeping a lithium battery warm in cold weather, winter is a period that calls for extra attention and work. When you’re out and about enjoying the winter, you need to take some precautions to ensure that your lithium battery stays warm. These five excellent suggestions will help you keep your lithium batteries warm during chilly weather.
1.Put on a battery blanket first. In cold weather, batteries are kept warm by battery blankets, which are insulated blankets. To prevent the battery from being exposed to the cold, they are made to fit around it tightly. By retaining the heat produced by the battery and shielding it from the weather, they offer effective insulation to lessen the exposure of the battery cells to the cold environment.
- Store your battery in a battery box or other insulated storage item. Compact, reusable, and constructed from a range of materials, insulated storage units and battery boxes keep lithium batteries warm by reducing the quantity of freezing air that comes into contact with the battery’s constituent parts. Additionally, the insulation in them adds warmth and aids in retaining any heat produced by the battery.
- Before leaving in the cold, charge them using solar panels. Lithium batteries deplete more quickly in colder climates than in warmer ones. Before you leave the house, it’s a fantastic idea to utilize solar panels to charge lithium batteries. Even on the coldest days, solar panels are an excellent way to produce a regular and reliable supply of electricity that will keep your batteries charged and at their ideal temperature.
- Store lithium batteries in a garage or other warm place. Even in cold weather, keeping your battery warm and functional can be greatly aided by placing it in a heated location, such a garage. By doing this action, you can lessen the rate at which cold temperatures harm batteries.
- Apply heat from a battery. An excellent way to insulate lithium batteries and keep them warm, even in the coldest weather, is with battery warmers. You may extend the life of your battery in cold weather by using battery heaters made especially for lithium batteries, which have programmable temperatures and settings.
