Creation of the anode of lithium-ion batteries and the study of electrochemical characteristics

Abstract

In connection with the energy crisis in the world, scientists are considering various alternative sources of energy. Environmental pollution and lack of fossil resources are pushing scientists and engineers to develop new, more efficient ways to obtain and store energy without polluting the environment. Currently, lithium-ion batteries are an alternative energy storage medium and have been well studied. Lithium-ion batteries have a small size, light weight, long service life, high power density, low discharge rate, and no residual memory effect. The ability to efficiently store and release lithium ions in the anode material determines the capacity, specific power and service life of the battery. The electrochemical characteristics of these anode materials are carefully analyzed using cyclic voltammetry, galvanostatic cyclic charge/discharge methods. These description methods determine the electrochemical characteristics of anode materials, including charge/discharge capacity. Due to its environmental friendliness, relatively energy intensity and stable performance, lithium-ion batteries are used in many industries. Researchers are conducting research in the direction of increasing the price, capacity, small size, length of service life of lithium-ion batteries. The anode material was obtained from Activated Carbon, which was made by processing rice husks in two stages to obtain it. Carbonization of rice husks in the first stage and chemical activation in the second. To obtain the electrochemical characteristics of the electrode, a coin-shaped CR2032 brand battery was developed. The resulting material was examined using a scanning electron microscope and X-ray phase analysis.
