Li-Ion Battery

Lithium-ion batteries store energy and create an electrical potential between the positive and negative terminals of the battery using lithium ions. They are one of the newest battery technologies available and are currently the most expensive. However, these batteries have the highest storage capacity, longest lifespan, and fastest charging time compared to other battery types.

In addition, various other benefits make lithium batteries the battery of choice in most applications.

How Does A Lithium-Ion Battery Work?
Lithium-ion batteries contain multiple individual battery cells wired together along with a battery management system (BMS). The BMS helps balance the charge across cells and monitors the battery’s health and temperature to ensure optimal performance and lifespan. Each battery cell consists of four main components: the cathode, the anode, an electrolyte, and a separator.

While a lithium-ion battery discharges, lithium ions move through the electrolyte and pass through the separator from the cathode (positive terminal) to the anode (negative terminal). While the battery charges, this process is reversed. The flow of the ions creates an electrical potential called “voltage.” The separator allows the lithium ions to pass through but blocks electrons and forces them to move through your electronics and providing them the power to operate.

Types of Lithium-Ion Batteries
There are multiple types of lithium-ion batteries available, and each is named for its active materials and chemical makeup. The different types of lithium batteries excel in various applications and all have pros and cons.

For example, lithium iron phosphate (LiFePO4) is popular for replacing 12-volt lead-acid batteries. Lithium iron phosphate batteries have excellent chemical and thermal stability, which makes them safe for rugged applications. Additionally, they have a long life cycle and a high current rating. We use this chemistry in our Battle Born Lithium Batteries.

Another type that you’ll commonly see is lithium cobalt oxide (LiCoO2). You’ll often find this battery type in consumer electronic equipment such as DSLR cameras, mobile phones, tablets, and even laptops. The LiCoO2 is less stable and has a shorter lifespan than LiFePO4 but can pack a big punch due to its high energy density.

Lithium manganese oxide (LiMn2O4) is also commonly seen in lithium-ion battery-powered devices. The chemistry of LMO batteries allows for a high current flow and fast charging but leads to a shorter lifespan. You’ll often see this type of battery in power tools, medical tools, or even some electric vehicles.

What Are The Benefits Of Using Lithium-ion Batteries?
There is a long list of benefits when it comes to using lithium-ion batteries. Let’s look at a few reasons why many manufacturers and consumers choose to use this type of battery.

One of the most significant benefits is longevity. When you choose a lithium-ion battery, you can typically expect a 3-5 times longer life expectancy than any other battery on the market. While lithium batteries are more expensive than their counterparts, they are more cost-effective when you factor in the increase in charge cycles.
