The adoption of lithium-ion batteries has risen significantly in the present times. This is because Li-ion batteries endure for a long time, hold a high power frequency, and are affordable to manufacture. Lithium-ion battery advantages include its rechargeable and highly portable nature. This is the reason why they get frequently employed in electric vehicles. However, just like every other technology, lithium-ion batteries have their share of advantages and disadvantages.

A lithium-ion battery or Li-ion battery is a type of rechargeable battery composed of cells in which lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge and back when charging, Li-ion batteries are able to be recharged hundreds of times and are more stable, They tend to have a higher energy density, voltage capacity and lower self-discharge rate than other rechargeable batteries, This makes for better power efficiency as a single cell has longer charge retention than other battery types Use a two to three-year life expectancy for batteries that do not run through complete charge cycles. Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible, The minimum lifespan most manufacturers expect from lithium-ion batteries is around 5 years or at least 2,000 charging cycles. But, if well cared for and used in proper conditions, lithium-ion batteries can last as long as 3,000 cycles.
