What are Lithium Batteries?

Lithium batteries have been used for so many things in today’s world. The importance of lithium batteries cannot be over-emphasized. This is why we have decided to discuss the benefits of lithium batteries today. It will help if you read through this guide keenly.

What are lithium batteries?

A lithium battery is formed of four key components. It has the cathode, which determines the capacity and voltage of the battery and is the source of the lithium ions. The anode enables the electric current to flow through an external circuit and when the battery is charged, lithium ions are stored in the anode.

The electrolyte is formed of salts, solvents, and additives, and serves as the conduit of lithium ions between the cathode and anode. Finally, there is the separator, the physical barrier that keeps the cathode and anode apart.

Lithium batteries are often used to directly replace lead-acid batteries because they have very similar charging voltages. A four-cell LiFePO4 Battery (12.8V), will typically have a max charge voltage between 14.4-14.6V (depending on manufacturers’ recommendations). What’s unique to a lithium battery is that they do not need an absorption charge or to be held in a constant voltage state for significant periods of time.

Typically, when the battery reaches the max charge voltage it no longer needs to be charged. The discharge characteristics of LiFePO4 batteries are also unique. During discharge, lithium batteries will maintain a much higher voltage than lead-acid batteries typically would under load. It’s not uncommon for a lithium battery to only drop a few tenths of a volt from a full charge to 75% discharged. This can make It difficult to tell how much capacity has been used without battery monitoring equipment.

Applications of Lithium Batteries

Here are the top uses for rechargeable lithium batteries:

• Emergency Power Backup or UPS (Uninterruptible Power Supply)

Owning a lithium battery for an alternative power backup or UPS protects you from traditional power loss or instability. It is different from a generator or other emergency power backup in that it provides nearly instant power in order to run (or safely shut down) the equipment it is connected to. Emergency power backup systems benefit critical equipment: computers, communication technology, and medical technology.

• Steady Electric and Recreational Vehicle Power

Lithium batteries give reliable, stable, long-lasting power – the best solution for staying comfortable and safely exploring remote locations. With a life span of over ten years, lithium batteries provide power for long journeys and lose little power between uses. Lightweight lithium batteries power your RV or electric vehicle with increased efficiency due to reduced weight and size as compared to lead-acid batteries.

Don’t let the absence of hard-wired electricity limit your security. Do you need to monitor remote perimeters, a fleet of vehicles, job sites, or a temporary location where a permanent alarm system installation is not possible? Secure any of these difficult locations with a surveillance or alarm system powered by lithium batteries.

Rechargeable lithium batteries are ideal for remote monitoring systems due to their long life, small size and not losing power via self-discharge during the time that your system is inactive. Lithium batteries have a self-discharge rate that is 10 times lower than lead-acid batteries, making them ideal for situations where they are not under continuous use.

• Personal Freedom with Mobility Equipment

Modern technology has made daily life easier for people with mobility restrictions. From electric wheelchairs to stair lifts, numerous individuals depend on reliable mobility technology to live an independent life. Lightweight lithium batteries are the ideal choice for mobility equipment, as they offer size customization, a longer life span, fast charging, a low self-discharge rate, and extended run time when compared to lead-acid.

• Portable Power Packs That Eliminate Downtime

Rechargeable lithium batteries are well-known for powering our phones and the latest lightweight laptop computers. Lithium batteries are lighter and smaller than lead-acid batteries. They also tolerate movement and temperature changes, as well as maintain their power delivery during use.

When they do need a charge, lithium batteries recharge much faster than lead-acid batteries. Custom lithium battery options also allow you to transition your existing technology to a longer-lasting and more efficient portable power pack.

Rechargeable lithium batteries are both economical and durable under challenging conditions. When dependable performance is required, lithium batteries offer a safe and long-lasting solution.

FACTORS THAT SHORTEN THE LIFE OF LITHIUM BATTERIES

The internal factors of lithium batteries

• Side reactions of lithium batteries;
• Irreversible consumption of active materials in lithium batteries;
• For large lithium batteries for sale, the battery’s working current is large, and the heat dissipation is slow, which is easy to cause damage to the battery structure;
• If safety protection measures are attached to the lithium battery, it must be maintained by the power supplied by the lithium battery.

The working environment of lithium battery

• The improper working environment of lithium batteries will directly affect the length of life. The charging temperature of a lithium battery is 0℃～45℃, and the discharge temperature of a lithium battery is -20℃～60℃;
• Do not overcharge or over-discharge the lithium battery during the charging and discharging process of the lithium battery;
• Avoid incorrect operation methods when working with lithium batteries: short circuit;
• Use a properly matched lithium battery charger to charge the battery;
• The newly charged lithium battery for the bike should be put aside for half an hour, and then used after the performance is stable, otherwise, it will affect the battery performance.

Types of lithium-ion batteries

Lithium-ion batteries come in a variety of shapes and sizes, and not all of them are made equal. Below are descriptions of six different lithium-ion battery types, as well as their compositions and common applications.

• Lithium Cobalt Oxide

Lithium cobalt oxide batteries are manufactured from lithium carbonate and cobalt and are also known as lithium cobaltate or lithium-ion cobalt batteries. These batteries are used in cell phones, laptops, and electronic cameras because of their high specific energy. They have a cobalt oxide cathode and a graphite carbon anode, and lithium ions migrate from the anode to the cathode during discharge, with the flow reversing when the battery is charged.

This battery has a few disadvantages, including short battery life and low specific power. We also want to let you know that these batteries are not as safe as other varieties. Despite this, they are a popular choice for cell phones and other portable electronic devices because of their properties.

• Lithium Manganese Oxide

Lithium manganese oxide batteries are sometimes known as lithium manganate or lithium-ion manganese batteries, or li-manganese or manganese spinel batteries. The technology for this sort of battery was initially discovered in the 1980s, with the first publication in the Materials Research Bulletin in 1983. Moli Energy manufactured the first commercial lithium-ion cells using lithium manganese oxide as the cathode material in 1996.

High-temperature stability distinguishes lithium manganese oxide batteries from others, which are also safer than other lithium-ion battery types. As a result, they’re frequently found in medical equipment and devices, but they can also be used in power tools, electric motorcycles, and other applications. Lithium manganese oxide batteries can also be used to power laptop computers and electric vehicles.

• Lithium Iron Phosphate (LFP)

Phosphate is used as a cathode in lithium iron phosphate batteries, often known as li-phosphate batteries. They have low resistance qualities, which improve their thermal stability and safety.

Durability and a long lifecycle are other advantages – fully charged batteries can be kept with no effect on the battery’s overall charge life. When the lengthy battery life of Li-phosphate batteries is considered, they are frequently the most cost-effective option. The lower voltage of the lithium-phosphate battery, on the other hand, means that it has less energy than other lithium batteries.

As a result, these batteries are frequently used in electric bikes and other applications requiring a long lifecycle and high levels of safety. These batteries are also commonly used in electric vehicles.

• Lithium Nickel Manganese Cobalt Oxide (NMC)

Lithium Nickel Manganese Cobalt Oxide batteries, often known as NMC batteries, are constructed of a variety of materials that are universal in lithium-ion batteries. A cathode constructed of a mix of nickel, manganese, and cobalt is included.

NMC batteries, like other lithium-ion battery types, can have a high specific energy density or a high specific power. They can’t have both features, though. This battery is most commonly seen in power tools and automobile powertrains.

Some battery manufacturers plan to convert their battery chemistry to a larger percentage of nickel to utilize less cobalt, the price of these batteries may drop even more in the future. Because of its low self-heating rate, this battery type is often used in electric vehicles.

• Lithium Nickel Cobalt Aluminum Oxide

NCA batteries, or lithium nickel cobalt aluminum oxide batteries, are making their way in electric vehicles and grid storage.

Although NCA batteries are not widely used in consumer electronics, they have great potential in the automobile industry. NCA batteries offer a high-energy choice with a long lifespan, but they are less safe than other lithium-ion battery types and are rather expensive. To ensure driver safety, NCA batteries must be accompanied by monitoring systems.

Given the widespread use of NCA batteries in electric vehicles, demand for these batteries may increase as the number of electric vehicles grows.

• Lithium Titanate

Finally, lithium titanate, often known as lithium-titanate, is a type of battery that has a growing number of uses. Because of its superior nanotechnology, the lithium-titanate battery has an extremely rapid recharge time.

Lithium-titanate batteries are being employed by makers of electric vehicles and bicycles, and this type of battery has the potential to be used in electric buses for public transit. However, these batteries have a lower intrinsic voltage or energy density than other lithium-ion battery types, which might cause problems when it comes to efficiently powering automobiles. Despite this, lithium titanate batteries have a higher density than non-lithium-ion batteries, which is a benefit.

These batteries could be used for military and aerospace applications, as well as storing wind and solar energy and constructing smart grids. Furthermore, according to Battery Space, these batteries could be employed in power system system-critical backups.

After understanding the types of lithium-ion batteries, let’s understand two of these batteries in depth. These batteries are NMC and LFP.

• Lithium Nickel Manganese Cobalt Oxide (NMC)

A cathode combination of nickel, manganese, and cobalt is one of the most successful Li-ion systems. These systems, like Li-manganese, can be modified to serve as Energy Cells or Power Cells.

NMC in a 18650 cell for moderate load conditions has a capacity of about 2,800mAh and can produce 4A to 5A; NMC in the same cell can be optimized for specific power. For example, it can have a capacity of just about 2,000mAh but can deliver a continuous discharge current of 20A.

The capacity of a silicon-based anode can be increased to 4,000mAh and beyond, but at the cost of reduced loading capability and shorter cycle life.
