Lithium ion, or lithium ion battery is a kind of rechargeable battery, lithium battery is divided into lithium battery and lithium ion battery. Cell phones and laptops use lithium ion batteries, which are commonly referred to as lithium batteries. Batteries generally use materials containing lithium as electrodes, which are representative of modern high-performance batteries. There are many lithium ion battery applications, but they are most commonly found in the electronics industry. Lithium ion batteries provide portable power to power electronic gadgets such as mobile phones, laptops, and tablets. Lithium ion batteries are also used to provide energy for medical equipment, electric vehicles and power tools. Thus there are AGV battery, robot battery, batteries for RV, golf carts and cleaning machines etc.
In addition to the electronics industry, lithium is the main mineral in mining, manufacturing, energy storage and many other industries. Due to its numerous industrial uses, the importance of li ion battery pack cannot be overemphasized: it is likely to be one of the most critical developments in the modern world, and without it, the 21st century cannot come.
Lithium ion battery is a kind of secondary battery (rechargeable battery), which mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. In the process of charging and discharging, Li+ intercalates and deintercalates back and forth between the two electrodes: during charging, Li+ deintercalates from the positive electrode and inserts into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Although lithium electronics has a history of more than 50 years, lithium batteries are still improving. Scientists are constantly breaking through the limits and boundaries of current lithium-ion technology, by experimenting with new methods that combine electrolyte, anode, and cathode to create a battery that is more energy-efficient, more cost-effective, and safer than its current form. From the use of relatively cheaper (but safer) materials, such as silicon and vanadium oxides, to the creation of "nanometer-scale" in batteries to create more surface area, scientists are thinking of new ways to improve the current performance of lithium-ion batteries. Energy capacity and safety measures.
