1.Description of Lithium battery
Lithium-ion battery (Li-ion battery) is a common rechargeable battery technology widely used in mobile devices, electric vehicles, portable electronics, and many other fields. It consists of a single or multiple Li-ion cells and a protective circuit board, and once the battery is installed in a device with a protective circuit board, it is ready to operate. It is noted for its high energy density, light weight and long life. This rechargeable battery was invented in 1859, and its lead-acid chemistry is still used today in automotive batteries that start internal combustion engines, while the research underpinning lithium batteries was published in the 1970s, followed by the first commercial lithium battery in 1991. Lithium batteries have continued to evolve and have become widely used as an indispensable necessity in our daily lives. Today, lithium is the most popular rechargeable battery chemistry, and lithium batteries power the devices we use every day, such as our cell phones and electric cars.
2. Working principle of lithium battery
THE BASICS
A battery is made up of an anode, cathode, separator, electrolyte, and two current collectors (positive and negative). The anode and cathode store the lithium. The electrolyte carries positively charged lithium ions from the anode to the cathode and vice versa through the separator. The movement of the lithium ions creates free electrons in the anode which creates a charge at the positive current collector. The electrical current then flows from the current collector through a device being powered (cell phone, computer, etc.) to the negative current collector. The separator blocks the flow of electrons inside the battery.
CHARGE/DISCHARGE
While the battery is discharging and providing an electric current, the anode releases lithium ions to the cathode, generating a flow of electrons from one side to the other. When plugging in the device, the opposite happens: Lithium ions are released by the cathode and received by the anode.
During a discharge cycle, lithium atoms in the anode are ionized and separated from their electrons. The lithium ions move from the anode and pass through the electrolyte until they reach the cathode, where they recombine with their electrons and electrically neutralize. The lithium ions are small enough to be able to move through a micro-permeable separator between the anode and cathode. In part because of lithium’s small atomic weight and radius (third only to hydrogen and helium), lithium batteries are capable of having a very high voltage and charge storage per unit mass and unit volume.
3.Composition of Lithium battery
Different types of lithium batteries vary in their raw materials composition. While all the usual lithium battery types consist of 11 percent lithium and different amounts of cobalt, more advanced batteries include nickel and manganese in various ratios. But they are generally made up of the following components:
- Cathode or the positive electrode: Source of lithium ions that determines the batteries capacity and voltage
- Anode or the negative electrode: Section that stores and releases ions through an external unit
- Electrolyte: Medium that transports ions between the cathode and anode
- Separator: Barrier that prevents the cathode and anode from coming in contact with each other
These major components need to be present in a lithium battery in order to function properly.
4.Widely Application of Lithium battery
Lithium batteries are commonly used to power computers, cell phones, digital cameras, watches and other electronic devices. lithium batteries are often rechargeable (like the battery in your iPhone, laptop or Nintendo Switch, for example), while regular lithium batteries are usually single-use (like the batteries in toys, remote controls and smoke detectors). Unlike alkaline batteries, lithium batteries are reactive and contain hazardous materials. Because of this, you should never put them in your trash or recycling carts.Here are the top uses for rechargeable lithium batteries– from facilitating daily activities to providing essential emergency support:
Emergency Power Backup Or UPS (Uninterruptible Power Supply)
lithium batteries provide emergency back-up power in case of power loss or fluctuation. Office equipment like computers, as well as IT servers, need to keep running in case of power interruption to prevent data loss. Back-up power is also needed in the medical or health care industry to guarantee consistent power supply to life-saving medical equipment. Therefore, having a lithium battery for an emergency power backup or UPS can protect you from traditional power loss or instability and will give you great benefits of using eletronic when you need it. Because it is different from a generator or other emergency power backup in that it provides nearly instant power in order to run (or safely shut down) the equipment it is connected to. Emergency power backup systems benefit critical equipment: computers, communication technology and medical technology.
Dependable Electric And Recreational Vehicle Power
The automotive industry poses a demand for lithium battery packs to provide power source for electric, hybrid or plug-in hybrid electric vehicles. As lithium battery can store large amounts of energy and can be recharged many times, they offer better charging capacity and longer lifespan. Besides, lithium batteries offer reliable, stable, long-lasting power – the best solution for staying comfortable and safely exploring remote locations. With a life span of over ten years, lithium batteries provide power for long journeys and lose little power between uses. Lightweight lithium batteries power your RV or electric vehicle with increased efficiency due to reduced weight and size as compared to lead-acid batteries.
Reliable And Lightweight Marine Performance
lithium batteries continue to emerge as an alternative to gasoline and lead-acid batteries in powering work or tug boats and leisure boats like speed boats and yachts. lithium batteries provide quiet and efficient power source and can also be used to provide electricity to appliances inside the boat or yacht while it is on dock. What is more, lithium batteries will let you focus on the fun of being on the water, not on the worry of whether your marine motor starts at the end of a long day, although mixing water and electricity provides the potential for numerous problems. In addition, upgrading your boat to a long-lasting rechargeable lithium battery gives you years of reliable motor starts at a fraction of the weight of a traditional lead-acid battery.
Whether you need to power a small trolling motor, or power all of the conveniences of home on a yacht, lithium batteries are capable and dependable.
Solar Power Storage
We can look at the following set of data to prove that the demand for lithium batteries is increasing day by day：The use of solar power in the United States increased 30% from 2013 to 2014. Even in the desert, there are days when the sun doesn’t shine or times when your solar equipment needs repair. Avoid getting left in the dark with lithium batteries for solar power storage. Rechargeable lithium batteries are the best match for solar panels due to how they charge, and how fast. Solar panels produce low resistance charging, which is what lithium batteries require. In addition, lithium batteries charge quickly – allowing you to maximize the potential solar power storage from each day of sunlight.
