Lithium batteries: discover their advantages and how to maximize their lifespan
Lithium batteries are among the most advanced and widespread energy solutions today, used in fields ranging from sustainable mobility to industry, from nautical applications to domestic energy efficiency. Thanks to their high energy density, long lifespan, and low maintenance, they represent a technological revolution for the future.
Archimede Energia, a specialized manufacturer of lithium-ion accumulators and batteries, develops solutions tailored to meet the needs of an ever-evolving market. But what are the tangible advantages? And how can we make the most of them?
In this article, we will answer all these questions, offering a comprehensive overview of lithium batteries’ potential and the best practices for preserving and maintaining them over time.
Why choose lithium batteries?
Lithium batteries are not just one option among many: they represent the most technologically advanced solution currently available on the market. This is because they offer a range of advantages that other technologies, such as lead-acid or NiMH (Nickel-Metal Hydride) batteries, cannot provide.
High energy density: more power in less space
One of the main advantages of lithium batteries is their high energy density, which translates into the ability to store a large amount of energy in a compact and lightweight format. With an energy density ranging from 150 to 200 Wh/kg, they are far more efficient than traditional batteries, which rarely exceed 40 Wh/kg.
This feature is crucial for applications where space and weight are critical, such as in electric vehicles and portable devices.
Longevity: an investment that pays off
The average lifespan of a lithium battery is approximately 1,000-2,000 charge and discharge cycles, which puts them far ahead of traditional technologies. This means you can use a lithium battery for many years before needing to replace it.
In systems like home solar panels, this longevity significantly reduces maintenance and replacement costs, making lithium batteries a sustainable choice even from an economic perspective.
Fast charging and high energy efficiency
Time is precious, and lithium batteries prove it. Thanks to their advanced chemical structure, they enable fast charging, reaching up to 80% of their capacity in a short time. Moreover, next-generation lithium batteries support charging currents up to 10C, delivering even higher performance.
In addition, lithium batteries boast an energy efficiency exceeding 90%, meaning that almost all the energy supplied during charging is effectively stored, with minimal losses.
What happens if a lithium battery is fully discharged?
One of the most frequently asked questions by users concerns the behavior of lithium batteries in the event of complete discharge.
Built-in Protection to Prevent Damage
Lithium batteries are designed with protective systems that prevent irreversible damage in case of full discharge. However, it’s essential to know that discharging them to zero can still have negative effects on their overall lifespan.
In particular, a full discharge may:
- Reduce the energy storage capacity.
- Activate the protection system, requiring technical intervention to reactivate the battery.
How to Prevent Full Discharge
Experts at Archimede Energia recommend always keeping the charge level above 20%, especially when the battery is not used for long periods. Whenever possible, use a Battery Management System (BMS) to continuously monitor the charge level and avoid critical situations.
How to keep lithium batteries performing at their best
Keeping a lithium battery in optimal condition requires a few simple precautions, but it’s important to follow them carefully. Let’s look at the most useful tips together.
Proper Charging: Avoid Overcharging
To avoid overvoltage, it’s advisable to use chargers equipped with communication systems, ensuring the device automatically switches to maintenance mode once charging is complete. While many modern devices automatically stop charging, overheating can still pose a long-term issue.
Similarly, avoid completely discharging the battery: ideally, maintain the charge between 20% and 80% to ensure greater longevity.
Optimal Storage Conditions
If you plan not to use the battery for an extended period, store it in a cool, dry place with about 50% charge remaining. High temperatures above 45°C, or extremely low ones below 0°C, can damage the chemical structure of the cells.
Use High-Quality Chargers
Low-quality chargers can compromise the battery’s safety and lifespan. Investing in a certified and compatible charger is essential to protect your investment.
Minimal Yet Essential Maintenance
Lithium batteries don’t require the periodic maintenance typical of lead-acid batteries, such as topping up with distilled water. However, periodic checks of the management system (BMS) and the cell status can be beneficial, especially for professional applications.
The future of lithium batteries
According to a recent report by BloombergNEF, global demand for lithium batteries could reach 2 TWh (terawatt-hours) by 2030, driven by the increasing adoption of electric vehicles and energy storage systems.
In Europe, government incentives and a growing awareness of sustainability are accelerating the adoption of these batteries, with an annual growth rate exceeding 30% since 2020.
As a specialized manufacturer, Archimede Energia is committed to developing increasingly innovative and sustainable solutions to meet the needs of a constantly evolving market.
Investing in lithium batteries is a smart choice
Lithium batteries offer a unique mix of advantages: long lifespan, high efficiency, lightweight design, and minimal maintenance. However, to fully exploit their potential, it’s essential to understand their characteristics and adopt good usage and storage practices.
