li ion battery cell What is Lithium-Ion Battery and How Does it Work?
Lithium-Ion battery is a kind of battery used in the fields of cars, digital cameras, computers, watches, etc. Keep reading and learn about the internal work of this battery. Lithium-Ion batteries are used in many electronic devices such as mobile phones, MP3 players, laptops, etc. Because they are light. These batteries are rechargeable and have a high energy density compared to many other batteries. The amount of energy stored in the battery per unit volume is very high, and the energy stored in the battery is an electrical type of energy. This type of electrical energy is obtained from chemicals through chemical reactions. The loss of energy will also occur slowly. The basic function of any battery is composed of two important elements, electrode and electrolyte. The anode and cathode are two electrodes that conduct electrical energy (ions. When the cathode is connected to the positive pole of the battery, the anode is connected to the negative pole of the battery. The electrode is immersed in an electrolyte that acts as an ionic moving liquid medium. The electrolyte acts as a buffer and contributes to the electrochemical reaction in the battery. The movement of electrons between the electrolyte and the electrode generates current. How about lithium-The anode and cathode are composed of carbon and lithium oxide respectively. The electrolyte consists of lithium salt, which is dissolved in organic solvents. ). ), etc. , Dissolved in organic solvents such as ethylene carbonate, Diester carbonate and Diester carbonate. O), lithium (highly active alkaline metal) reacts violently with water to form hydroxide and hydrogen, which is not required at all. During charging, the lithium ion moves from the cathode to the anode, settling in the anode layer. The flow of lithium ion is through the electrolyte. When this process occurs, the battery is charged and the electrical energy is stored in it. During the discharge, the lithium ion moves from the anode to the cathode. When the battery is powered, in the external circuit, the motion of the electron is opposite to the direction of the lithium ion. Due to this movement of electrons, current is generated. Basically, the potential difference and resistance are generated between the electrodes, resulting in current flow. Ion movement occurs when the battery is powered by an external power supply. Now let's take a look at the chemistry happening on the electrode. -1--The circuit monitors the voltage and current levels in the battery. These switches are from the field-The effect transistor, which interrupts or interrupts the charging and discharging process after receiving the correct control signal from the controller IC. When the temperature of the control switch rises to a certain level, the fuse cuts off the current. This helps save the battery from the over current. The current in the battery is controlled by a thermal resistor, because it can change the resistance according to the current through it. Switches are also used for some lithium-The ion battery, not the thermal resistor, is used to prevent the circuit from overheating. Battery capacity I. e. The amount of charge it can store depends on the surface area of the electrode used. The number of charging and discharge cycles is increasing, and the charging speed is also very fast. But there was an explosion due to overheating. To prevent the battery from exploding, it is recommended to replace the battery frequently.
