A lithium-ion battery is a type of rechargeable battery which was proposed in the year 1970. Lithium-ion batteries are quite common nowadays. They can be easily located in a laptop, cell phones or MP3 players. These are used in portable electronics and electric vehicles.

Li-ion batteries are a family of rechargeable battery in which it moves from a negative electrode to the positive electrode during discharge and back when charging. The battery life of a lithium-ion cell can be described as:


  • Energy density ‚Äď Lithium-ion‚Äôs energy density is twice that of a nickel-cadmium. There is a potential for high energy density. The high battery voltage is 3.6 volts which allow battery pack designs with only one cell. Most of today‚Äôs mobile phones would run on a single cell. A nickel-based pack shall require three 1.2 volts cells connected in series.
  • Low maintenance ‚Äď This is an advantage that most of the batteries do not have. There is no memory and no scheduled cycling is required to prolong the battery life. The self-discharge is lower to the nickel-cadmium. This makes Li-ion cells suitable for modern fuel gauge applications.
  • Battery age- Lithium-ion battery age. They last two to three years even if they are unused. If a consumer needs to buy a new battery pack, they need to make sure that it is new because even if it is unused and old, it would not work very long. Manufacturing dates are too important.

Lithium-ion batteries contain high energy and low self-discharge. The most significant aspect of Li-ions is that they are not required to be maintained. These batteries comprise copper, nickel, and cobalt which makes it safe when we come around the issue regarding environmental concerns. Thus, it has improved the daily lives of consumers proving to be less toxic and easily recyclable.
