Abstract:

Rechargeable battery technology is evolving, driven by the accumulation of new knowledge and the invention of new materials. The rechargeable battery has been transformed into one of the main portable sources of electricity with wide application in everyday life (vehicles, telecommunications, information technology, etc.). The most common trend in the development of rechargeable batteries is the development of a battery with reduced weight and maintenance or non-serviceable rechargeable batteries for the whole period of service use such as lithium-ion ones. Lots of companies in recent years have mastered the production of such rechargeable batteries. Lithium-ion batteries (popularly known as Li-ion) are currently being developed most successfully. In 2012, they accounted for over 70% of total world battery production in this area, whereas in 2020 they accounted for about 85% of the world market. These batteries are most widely used in the manufacture of electric vehicles, mobile devices, and all types of technology. Li-ion batteries or LIB belong to the rechargeable types of batteries. In this type of battery, lithium ions move from the negative electrode to the positive electrode during discharge and vice versa when charging. Li ion batteries are common in consumer electronics. They are one of the most popular types of rechargeable battery for portable electronics. In addition, Li ion batteries find their application in the power supply of military, electric vehicles as well as space applications. Lithium-ion batteries are more expensive than NiCd batteries but operate over a wider temperature range with a higher energy density.

In this report, based on research, acquired knowledge and a great deal of competence about lithium-ion batteries, we solve the following problems together with some students:
1. We describe a scheme of work
2. Making a lithium-ion battery
2. 1. Study and selection of materials for lithium-ion batteries
2. 2. Execution of the lithium-ion battery connection scheme
2. 3. The finished product of a lithium-ion battery.
