How Lithium-Ion Batteries are made and Why are they Important?

In recent years, Li-ion batteries have been improved remarkably. In contrast to other types of battery technology, they offer some benefits and also have a few enhancements. 

However, it is important to consider not just the benefits but also the limitations of these batteries to get the most out of Li-ion battery technology. 

To better play the abilities, these batteries can be used in several ways.

How Lithium-ion Batteries Are Made?

Lithium-ion batteries are a link in the rechargeable battery series. It mainly consists of a combination of three elements- a negative electrode, a positive electrode, and electrolyte. 

Such batteries are used for carbon negative electrodes whereas oxides are used for positive electrodes. Lithium solder is for electrolytes. 

The biggest feature of lithium batteries is that they can increase and decrease their voltage according to the need. 

At the same time, it can also be made into a small packet. This is the reason why it is being used indiscriminately in mobile devices like mobile, laptop tablets. In colloquial language, it is called Ion battery.

Why Is A Lithium-Ion Battery Important?

  • Lithium is the lightest metal that provides high energy density, and also has the highest electrochemical potential.
  • Lithium-ion’s energy density is typically twice that of standard nickel-cadmium.
  • The energy density of iron ion batteries is 350 watts/kg under normal conditions, while the lithium-ion batteries have an energy density of 220 watts/kg.
  • Battery packs can be designed using only one cell with a high cell voltage of 3.6 volts capacity.
  • Lithium-ion batteries ’ maintenance is much simpler and less expensive.
  • The load characteristics of these batteries are reasonably good and behave similarly to nickel-cadmium in terms of discharge.
  • There is no need for any special repair cycle to prolong the battery usage period.
  • In addition, its self-discharge is less than half that of nickel-cadmium, making lithium-ion suited for modern fuel applications.
  • Lithium-ion batteries cause little damage during disposal.
  • These batteries are an example of the wireless technology revolution that makes portable compact disc players, digital wristwatches, laptops, and current mobile phones collaborative, making them easy to save.

Pros Of Lithium-Ion Battery:

  • High-voltage single-cell operating voltage is 3 times the voltage of the Ni-Cd and Ni-MH batteries (3.2V lithium iron phosphate).
  • The actual specific energy produced by the specific energy is approx. 555Wh / kg, which means the material will achieve a specific capacity of 150mAh / g or more, near at around 88 percent of the theoretical value (3–4 times Ni-Cd, 2–3 times Ni-MH).
  • Cycle life typically can exceed 500 times or over 1000 times, and phosphate lithium iron can exceed 2,000 times. The longevity of the battery would double the competitiveness of the smaller current discharge systems.
  • The strong output of protection, no pollution, no impact of memory. A modern lithium-ion battery type is responsible for the development of short circuits of metal lithium dendrites as a Lithium-ion battery in the predecessor of Li-ion, which minimize their application to the Li-ion, namely cadmium lead.
  • Is it free from mercury and other elements of environmental contamination which is a big downside to Ni-Cd batteries (for example sintered), part of the mechanism is the “speed-up effect.”
  • At room-temperature for 1 month, which is around 2%, the rate of self-discharge of Li-ion is fully charged, which is below 25 to 30% of Ni-Cd, and below 30 to 35% of the MH.
  • Fast Charging 1C charging 30-minute capacity can cross more than 80% of nominal capacity, and a ferrophosphorus battery in 10 minutes can go up to 10% of nominal capacity.
  • The temperature of operation is -25 ~45 °C. It is predicted to grow to -40 ~ 70°C by raising the electrolyte and the positive electrode.
  • Consumption: No Blast (gas flame barbecue battery)

Cons Of Lithium-Ion Battery:

  • Safety circuits are required to maintain their safe operation.
  • The lack of capacity over time for most lithium-ion batteries is a matter of concern.
  • Its production cost is about 40 percent more than that of nickel-cadmium.


Although not inherently an advantage or disadvantage, it is to be noted that lithium-ion batteries must be stored in a cool place so that the aging process of lithium-ion slows down.
