Lithium Ion Battery Advantages & Disadvantages

With the rapid advancement of lithium-ion battery technology, the disadvantages are being addressed and the overall technology is being enhanced.

Lithium-ion batteries and cells are more suited for some applications than others due to their characteristics. They have a higher voltage and deliver higher amounts of charge than other battery technologies, and they can be more expensive than other types. This makes them more suitable for some electrical circuit designs than other forms of battery technologies, but it may also make them less suitable in other circumstances.

Lithium-ion battery advantages

There are numerous advantages to adopting a lithium-ion battery cell. As a result, the technology is increasingly being used for a wide range of applications. Everything from small electronic gadgets to smartphones and computers, as well as automobiles and a variety of other uses.

When deciding between a lithium-ion battery and a lead-acid battery or a nickel-metal hydride battery (NiMH battery), it’s important to consider the benefits.

Because of the benefits of Li-ion technology, these batteries are finding an expanding number of uses, and as a result, a lot of research and development is going into them.

The following are some of the advantages of lithium-ion batteries:

High energy density:

One of the most significant advantages of lithium-ion battery technology is its high energy density. There is always a need for batteries with a much better energy density as electronic equipment such as mobile phones need to operate longer between charges while still consuming more power.

NiMH batteries, for example, would not be able to deliver the charge capacity required by today’s smartphones. A smartphone powered by Nickel Metal Hydride batteries would not last long enough, especially if the battery had to fit within the same size limits.

There are also several power uses, ranging from power tools to electric cars. Lithium-ion batteries have a significant advantage in terms of power density. Electric vehicles also require high-energy-density battery technologies.

Self-discharge:

The self-discharge rate of many rechargeable batteries is an issue. The rate of self-discharge of lithium-ion cells is substantially lower than that of other rechargeable cells such as Ni-Cad and NiMH. It is normally over 5% for the first four hours after being charged but thereafter drops to around 1% or 2% per month.

Low maintenance:

One of the most significant advantages of lithium-ion batteries is that they do not require any maintenance in order to function properly.

To avoid the memory effect, Ni-Cad cells have to be discharged on a regular basis. Because lithium-ion batteries and cells are unaffected. This method, as well as others identical to it, is not required.

Lead-acid cells, too, require care, with some requiring the battery acid to be topped up on a regular basis.

Fortunately, one of the benefits of lithium-ion batteries is that they do not require any active maintenance.

Cell voltage: 

Each lithium-ion cell produces roughly 3.6 volts of power. This offers a lot of benefits. The voltage of each lithium-ion cell is higher than that of typical nickel-cadmium, nickel-metal hydride, and even standard alkaline cells at approximately 1.5 volts and lead-acid at roughly 2 volts per cell, needing fewer cells in many battery applications. A single cell is all that is required for smartphones, which simplifies power management.

Load characteristics: 

A lithium-ion cell or battery’s load characteristics are quite good. They maintain a rather steady 3.6 volts per cell until the last charge is used up.

No requirement for priming:  

Some rechargeable batteries need to be primed before they may be used for the first time. One of the advantages of lithium-ion batteries is that they are delivered fully functional and ready to use.

Variety of types available:  

Lithium-ion cells come in a variety of shapes and sizes. This benefit of lithium-ion batteries could imply that the appropriate technology can be used for the purpose at hand. Some lithium-ion batteries have a high current density, making them excellent for consumer electrical devices. Others may deliver even larger currents, making them perfect for power equipment and electric vehicles.

Other advantages of using lithium-ion batteries and cells may exist for some applications. A single cell with a cell voltage of just over 3 volts may be sufficient for many applications. A single cell is used in the majority of mobile phones.

Other applications may have their own criteria that indicate the employment of a lithium-ion battery or cell in an electronic circuit or for an electrical application.

Lithium ion battery disadvantages

As with any technology, there are some drawbacks that must be weighed against the benefits. Lithium-ion batteries and cells aren’t flawless, and they do have some flaws.

Although lithium-ion battery technology has drawbacks, this does not rule out the possibility of overcoming or at the very least mitigating these drawbacks and achieving exceptional performance.

Knowing the drawbacks allows for workarounds to be incorporated into the electronic design or electrical system, for example, to mitigate the effects of the flaws.

The following are some of the downsides of lithium-ion batteries:

Protection/battery management system required: 

Lithium-ion batteries and cells are less durable than other rechargeable technologies. They must be safeguarded against being overcharged and discharged too far. In addition, the current must be kept below safe limits. As a result, one downside of lithium-ion batteries is that they require protection circuitry to guarantee that they remain within their acceptable operating limits.

Fortunately, modern integrated circuit technology allows this to be easily implemented into the battery or, if the battery is not interchangeable, into the equipment. The battery management circuitry is integrated, allowing li-ion batteries to be used without any particular understanding. They can be left on charge until the battery is fully charged, at which point the charger will turn off the power.

Aging:

One of the most significant problems of lithium-ion batteries for consumer gadgets is that they age. This is dependent not only on the time or calendar but also on the number of charge-discharge cycles that the battery has gone through.

Typically, batteries can only tolerate 500 to 1000 charge-discharge cycles before their capacity degrades. This number is rising as li-ion technology advances, but batteries will eventually need to be replaced, which might be a problem if they are integrated into equipment.

Lithium-ion batteries age whether or not they are in use. Regardless of consumption, there is a time component to the capacity loss.

When storing a normal consumer lithium cobalt oxide, LCO battery, or cell, it should be partially charged (about 40% to 50%) and kept in a cold storage place. The life of the product will be extended if it is stored in these circumstances. one of the most significant lithium-ion battery drawbacks for consumers

Transportation:

This drawback of lithium-ion batteries has become more apparent in recent years. Many airlines have a limit on the number of lithium-ion batteries they can carry, which means they can only travel via ship.
Lithium-ion batteries are frequently required in carry-on luggage for plane travelers, though this may alter depending on the security situation. However, the number of batteries available may be limited. Separate lithium ion batteries must be protected from short circuits via protective covers, etc. It is especially critical where large lithium-ion batteries, such as those used in huge power banks, are concerned.

It is vital to confirm whether or not a large power bank can be carried before flying. Regrettably, the instructions are not always clear.

Cost:

The expense of lithium-ion batteries is a significant disadvantage. They are typically 40 percent more expensive to produce than nickel-cadmium cells. This is a significant consideration when contemplating their use in mass-produced consumer goods when any additional expenses are a significant consideration.

Developing technology: 

Despite the fact that lithium-ion batteries have been around for a long time, some people still regard them as a developing technology. This has the potential to be a disadvantage due to the fact that technology changes. However, because new lithium-ion technologies are constantly being researched, this can be a benefit when better alternatives become available.

Other issues with lithium-ion batteries

Although not always a benefit or disadvantage, lithium-ion batteries should be stored in a cold environment. The aging of lithium-ion batteries is slowed as a result of this (and other chemistries). Temperatures of roughly 15°C are recommended by the manufacturers. Furthermore, the battery should be half charged while being stored. A charge level of roughly 40% to 50% is usually recommended by manufacturers.

It is preferable not to fully charge or discharge lithium-ion cells and batteries in order to get the most out of them. The optimal operating range for the cells and batteries has been reported to be between 20% and 80%. Some battery management systems may ensure that the cells are never fully charged or discharged, and the levels they show may already reflect this.

Lithium-ion cells and batteries don’t like to be totally emptied, and they don’t want to be fully charged either. This is due to the fact that in either state, all of the lithium ions are taken from one electrode or the other, causing the electrode to disintegrate faster.

The advantages of Li-ion battery technology are numerous. As a result, the technology is widely used, and this trend is expected to continue. Understanding the benefits as well as the drawbacks or restrictions allows for the most effective usage of battery technology.
