Lithium-ion batteries are quite popular in the modern lifestyle being used in laptops, mobile phones or MP3 players. They are also referred to as lithium-metal batteries. These batteries contain high energy and low self-discharge. Li-ion batteries are highly used by the consumer market and industrial applications.


Lithium-ion cells could explode if the temperature is too high. It can only happen due to short-circuit or overcharging that could cause a fire. The best example, in this case, could be Note 7. Li-ions have a huge benefit as they have grown significantly over the year. The advantages of these batteries are:


  • Self-discharge ‚Äď Lithium-ion batteries self-discharge rate is much lower than the other rechargeable batteries such as Ni-Cad and NiMH. It is around 5% in the first 4 hours after being charged.
  • Low maintenance - One of the crucial advantages of Li-ion batteries is that they do not require maintenance to ensure their performance.
  • High energy density - Mobile phones need to operate longer between the charges while consuming more power. People require a battery with a much higher density of energy. The lithium-ion batteries are advantageous with its high power density.
  • Variety of types available - There are varieties of Li-ion batteries available. Some of them provide a high current density and are ideal for electronics. Others provide much higher current and are best for power tools and electric vehicles.


Li-ion cell technology has various benefits. There have been heavy improvements and numerous researches. It has made life easier for the modern people according to their needs. Li-ion batteries are highly used in a portable device. It is people’s first choice.
