Why do mobile phones utilize lithium batteries and their benefits?

Time: 2023-01-17 03:04:35

What does a mobile phone lithium battery mean?

  • mobile phone lithium battery is a battery that powers a mobile phone device using lithium ions. One of the most popular and essential cell phone accessories is a battery, and consumers nowadays are seeking batteries with bigger capacities and conveniences. 
  • Many smartphones and other gadgets run on lithium-ion batteries from mobile phones. These batteries perform better than average in terms of charge capacity, energy density, and discharge rate. Cell phone the most common kind of rechargeable battery used in cell phones is a lithium battery. However, they have numerous advantages, such as being lightweight and having a long lifespan. 
  • Then came the creation of lithium-ion batteries. Even now, people still employ them. They are more durable, thinner, and lighter. Charging happens faster. Any business may use them in their mobile devices as they can be produced in a wide variety of forms and sizes to accommodate various phone models. They may be recharged several times and have no memory effect, making them both environmentally friendly and worry-free. The cost is low, nevertheless.

Why are Lithium Batteries used in mobile phones?         

The mobile phone lithium battery is a superior and ideal option when compared to other battery technologies that may be employed in mobile devices. It has a better power density, charges more quickly, and lasts longer for longer battery life in a lighter design. The following distinguishes Li batteries for usage in mobile phones from other types:

  • Captures more energy:

 1 kilogram of battery, a lithium-ion battery has the capacity to store up to 150 watt-hours of power. This exceeds the storage capacity of the nickel-metal hydride battery by a wide margin. A lead-acid battery (used in vehicles) has a storage capacity of just 25 watt-hours per kilogram, compared to the 60 to 70 watt-hours that a nickel-metal battery can hold per kilogram. Due to lithium's high level of reactivity, a significant amount of power may be deposited in its atomic bonds. They have a high power solidity as a result.

  • Lighter Batteries:

Lithium batteries are often substantially lighter than most other types of batteries with the same capacity, even though they are not the lightest. They make cell phones incredibly light, which is why mobile manufacturers favour them. A Lithium battery's electrodes are built of compact carbon and lithium, which contributes to the battery's small weight.

  • Charges More Quickly and Easily:

The lithium battery makes charging a smartphone easier. It is not necessary to wait until your device is entirely depleted before recharging it because it is possible to connect it to electricity for a lengthy period of time without encountering any bad effects. It has no memory effect problems. Lithium batteries have the durability to sustain many charge/discharge cycles without losing their performance over time.

Shorter charge and discharge cycles are more comfortable for the chemical reactions taking place within lithium batteries than full discharge followed by a full recharge.

  • Low Discharge Rate and Low Maintenance Cost:

A lithium battery requires little upkeep. The battery cells are either harmless or barely harmful when discarded. It doesn't have a memory impact issue. Lithium batteries are perfect for use in devices because of their low self-discharge, which is less than partial that of nickel batteries and is just 5% in the first four hours after a full charge. However, the discharge rate drops to about 2% monthly.

What is the advantage of lithium batteries in mobile phones?

These devices are now being developed greatly due to the advantages of lithium technology and the increasing number of uses they are finding. The advantages of lithium batteries are as follows:

  • High energy density: 

The great energy density of lithium rechargeable batteries is one of its important rewards. Since electric devices like mobile phones should operate for extensive distances of time among charges while yet utilizing additional control, nearby is continuously a need for batteries with a noticeably improved energy compactness.

  • Self-discharge: 

Many rechargeable batteries have an issue with their high self-discharge rate. Lithium cells have a far lesser rate of self-discharge than further rechargeable battery types like Ni-Cad and NiMH. It characteristically drops to a rate of one or two percent each month after the initial four hours after recharging, when it was often about 5%.

  • Cell voltage: 

A power of around 3.6 volts is produced by each lithium cell. There are several advantages to this. Because each lithium-ion cell has a greater voltage than the average other battery, fewer cells are required in many batteries. Power management is considerably easier for cell phones because just one cell is needed.

  • No need for priming:

 Some rechargeable batteries require a priming step before their initial charge. Lithium-ion batteries have the benefit of not requiring this; they are delivered functional and ready to use.

  • A variety of varieties are offered:

 Lithium-ion batteries come in a number of different varieties. This benefit of lithium-ion batteries may allow for the adoption of the appropriate technology for a certain application. Several lithium batteries offer high current compactness, making them perfect for purchasing mobile batteries. Others are perfect for power tools and electric cars because they can deliver current levels that are substantially higher.


Using a cell phone is the best option for charging your mobile phone lithium battery. They may give your phone a dependable source of power because they are compact, strong, and long-lasting. All products of HI-CHIPCOM have obtained export certification for RoHS, UL, and CE, and their comprehensive ability is at the advanced domestic level.
