What are the working principles of lithium titanate batteries and lithium ion batteries

The working principle of lithium titanate battery Lithium titanate battery consists of positive and negative plates (the active material of the positive electrode is ternary lithium, and the negative electrode is lithium titanate), separator, electrolyte, tabs, and stainless steel (aluminum alloy) housing. The positive and negative plates are the electrochemical reaction area, the diaphragm and the electrolyte supply the transmission channel of Li+, and the tabs play the role of guiding current. When the battery is charged, Li+ migrates from the ternary lithium material to the surface of the crystal, is removed from the positive plate material, enters the electrolyte under the use of electric field force, passes through the diaphragm, and then migrates to the negative electrode lithium titanate crystal through the electrolyte. The surface is then embedded in the negative lithium titanate spinel structure material. At the same time, electrons flow through the aluminum foil of the positive electrode, flow through the tab, battery pole, load, negative pole, and negative tab to the aluminum foil electrode of the negative pole, and then flow to the lithium titanate negative pole through the conductor to balance the charge. When the battery is discharged, Li+ is deintercalated from the lithium titanate spinel structure material, enters the electrolyte, passes through the diaphragm, and then migrates to the surface of the ternary lithium crystal through the electrolyte, and then re-embeds in the ternary lithium material. At the same time, electrons flow to the aluminum foil electrode of the negative electrode through the conductor, and flow to the aluminum foil electrode of the battery positive electrode through the tab, battery negative pole, load, positive pole, and positive tab, and then flow to the ternary lithium positive pole through the conductor. To balance the charge. The basic principle of lithium titanate battery is that in the process of charging and discharging, the corresponding lithium ions are inserted and removed back and forth between the positive and negative electrodes to complete the charging and discharging of the battery and the power supply to the load. Lithium titanate battery has the advantages of small size, light weight, high energy density, good sealing performance, no leakage, no memory effect, low self-discharge rate, rapid charge and discharge, long cycle life, wide working environment temperature range, safe and stable green Environmental protection and other characteristics, so it has a very wide range of application prospects in the field of communication power supply. The working principle of lithium ion battery Lithium ion battery is a kind of rechargeable battery, which mainly depends on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when recharging the battery, 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. Generally, batteries containing lithium elements are used as electrodes. It is a representative of modern high-performance batteries. The charging and discharging process of lithium ion batteries is the process of intercalation and deintercalation of lithium ions. In the process of intercalation and deintercalation of lithium ions, it is accompanied by the intercalation and deintercalation of electrons equivalent to lithium ions. In the process of charging and discharging, lithium ions are inserted/de-intercalated and inserted/de-intercalated back and forth between the positive and negative electrodes, which is vividly called the rocking chair battery.
