Why is Lithium-ion Battery the Best?

Date: 2022-09-09 Share:

Today, the use of lithium-ion batteries has grown significantly in recent years. It is a common power source for a variety of everyday products ranging from small electronics to large appliances, including laptops, cell phones, and even electric vehicles, electrical energy storage systems, etc.


What Is the Lithium-ion Battery?

Lithium-ion battery, also known as the Li-ion battery, is a secondary battery (rechargeable battery) that works mainly by moving lithium ions between the positive and negative electrodes. Capable of deep cycling while maintaining power, the lithium-ion battery is lightweight and long-lasting, offering a high energy density and charging efficiency with low self-discharge to power the lives of millions of people every day.


How Does the Lithium-ion Battery Work?

During charging and discharging, Li+ is embedded and de-embedded back and forth between the two electrodes: when charging, Li+ moves from the positive electrode through the electrolyte, then embeds in the negative electrode and back when discharging.

Why Choose the Lithium-ion Battery?



The lithium-ion battery provides the same or even more capacity and energy at less than half the weight and size of other conventional batteries. The portable lithium system is a lightweight and compact option to reduce concerns about battery weight - more flexibility and easier to install! That means the lithium-ion battery can greatly increase energy output and runtime without increasing the size and weight of the battery pack.


Low Maintenance

Traditional rechargeable battery types, such as NiCd or NiMH batteries, have the "memory effect", also known as the "lazy battery effect", requiring regular maintenance by fully discharging and recharging. In contrast, there is no memory for Lithium-ion batteries, which means no periodic discharge is needed. And the lithium-ion battery can be recharged at any time without tedious maintenance, no matter how much battery capacity you have used.



In general, the lithium battery lasts 10 times longer than the lead-acid battery, providing up to 80% of the rated capacity after thousands of cycles. Unlike lead-acid batteries with an average lifespan of only two years, requiring careful maintenance and water replacements to avoid structural damage, their lifespan may be further reduced if not properly maintained.


Most lithium-ion batteries can last five years or more, making them an excellent cost-effective choice for the solar street light system, communication energy storage systems, and more industrial applications.

Low Self-discharge Rate

A major problem with many rechargeable batteries is the self-discharge rate, which is much lower in lithium-ion batteries than in other rechargeable batteries. Self-discharge is a natural and irreversible phenomenon - chemical reactions within the battery will reduce battery capacity, even if it is not used.


The nickel-based rechargeable batteries lose about 10-15% of their capacity after charging and another 10-15% per month. While the self-discharge rate of lithium-ion batteries peaks at about 5% in the first 24 hours after charging and then gradually decreases to 1-2% per month.


High Energy Density

Lithium is a highly reactive element that can release and store large amounts of energy, allowing for high charging and discharging rates. As a result, lithium-ion batteries are fast and efficient - fast charging minimizes downtime, and high discharge rates are perfect for a burst of power.


High energy density is a clear advantage of lithium-ion battery technology - high energy capacity in a small size, providing maximum versatility for all types of power applications. In addition, the efficiency of lithium-ion batteries is unparalleled, with various stress situations, temperature fluctuations and energy depletion barely affecting the power delivery, eliminating the need to worry in situations that will exhaust the battery or run in extreme weather.



Lithium-ion technology has always been a hot topic in the battery field. By now, you should have figured out why the lithium-ion battery is a smart long-term solution worth investing in. However, looking for trustful li ion cell manufacturers may not be an easy task.
