The myths about lithium batteries: truths and misconceptions debunked

Lithium batteries have become an essential part of our daily lives, powering smartphones, laptops, electric cars, and even renewable energy storage systems. However, many misconceptions have arisen around this technology, often causing confusion and misinformation.

Let’s analyze the most common beliefs about lithium batteries and the scientific truths that debunk them.

1. Lithium batteries degrade rapidly

One of the most widespread myths is that lithium batteries have a very short lifespan. In reality, these batteries are designed to withstand thousands of charge-discharge cycles, maintaining significant capacity even after years of use. With proper charge management and controlled temperatures, degradation is very slow. On average, a lithium-ion battery can sustain between 500 and 3,500 cycles before it starts to progressively lose capacity.

2. Lithium batteries are dangerous and can explode

Another common misconception concerns the safety of lithium batteries. While improper use or manufacturing defects can cause overheating or malfunctions, modern Battery Management Systems (BMS) monitor temperature, voltage, and current to prevent issues. The risk of explosion is extremely low when using certified batteries and high-quality devices.

3. You need to fully discharge a battery before recharging it

This belief stems from older nickel-cadmium batteries but does not apply to lithium batteries. In fact, completely discharging a lithium battery can cause irreversible damage. It is preferable to maintain the charge between 20% and 80% to prolong its lifespan.

4. Lithium batteries fully discharge when not in use

Some people believe that an unused lithium battery will discharge completely over time. In reality, lithium batteries have a very slow natural discharge, especially when stored at an appropriate temperature. However, leaving them fully discharged for long periods can damage their internal chemistry, so it is recommended to store them with a charge level between 40% and 60%, recharging them monthly.

5. Lithium batteries do not perform well in cold temperatures

It is true that lithium battery performance can decrease in extremely low temperatures, but modern thermal management systems (such as integrated heating) mitigate this issue. Additionally, lithium iron phosphate (LFP) batteries are more tolerant to low temperatures compared to other lithium chemistries.

6. Lithium batteries pollute more than other technologies

Although lithium battery production requires significant energy resources, their environmental impact is lower compared to many alternatives, especially when considering their use in sustainable mobility and renewable energy storage. Moreover, lithium battery recycling is constantly evolving, and more companies are specializing in the recovery and reuse of valuable materials contained in battery cells.
