Sometimes abbreviated to Li-ion, lithium-ion batteries are used in a variety of different products, including wireless headphones, appliances big and small, hand-held power tools, electronic toys, electric vehicles, and so much more. People rely on them every day, but despite how common they are, most don’t know anything about them aside from the fact that they provide power to things they use. Considering the massive growth that the Li-ion industry has been experiencing globally, we figured it would be beneficial to go over how they work, the different types, the benefits, all their uses, and how long they typically last.
How does a lithium-ion battery work?
Lithium-ion batteries are comprised of multiple individual battery cells. Each cell is made up of a cathode (positive terminal), anode (negative terminal), electrolyte, and a separator. These cells are wired together along with a battery management system (BMS) which helps balance the charge while also monitoring the battery’s charge and internal temperature. When the battery discharges, lithium ions go through all four components – moving through the electrolyte from the cathode to the anode while passing through the separator. This process is reversed when the battery is charging. The flow of the ions creates electronic potential, or voltage, and the separator slows these ions to pass through but blocks the electrons. Electrons are then forced to move through your electronics, providing the power needed to operate.
Types of lithium-ion batteries
- Lithium iron phosphate
- Lithium cobalt oxide
- Lithium manganese oxide
- Lithium nickel manganese cobalt oxide
What are the benefits of using lithium-ion batteries?
- Up to 100% depth of discharge.
- Battery life of 3,000-5,000+ cycles.
- Much lighter than lead-acid batteries.
- Average discharge rate of 2-3% per month.
- Internal BMS that helps extend the battery’s lifespan.
- Can handle extreme temperatures.
Where can you use lithium-ion batteries?
Because they’re so durable and lightweight, lithium-ion batteries have a wide range of applications. They’re commonly used in household electronics like blenders, hand-held mixers, personal grooming devices, electric toothbrushes, hand-held power tools, and many others. Lithium-ion batteries are also used in electric cars because they’re able to provide so much energy in such a lightweight package. In addition to electric cars, other vehicles like RVs, sailboats, and motor boats. Lithium-ion batteries are also essential for anyone who lives off the grid, as it’s their main power supply.
How long do lithium-ion batteries last?
It depends on the type, but lithium-ion batteries can last from 300-700 charge cycles on the low end up to 3,000-7,000 cycles on the high end.
