Analysis of the difference between aluminum ion battery and lithium battery

The difference between aluminum ion battery and lithium battery Aluminum ion battery: The aluminum ion battery pack contains a negatively charged anode made of aluminum and a positively charged graphite cathode. Due to the excellent electrical conductivity and huge specific surface area of u200bu200bthree-dimensional graphite, it can be extremely large. To shorten the charging time of the battery. When discharging, aluminum ions move from the cathode to the anode; when charging, aluminum ions return to the cathode. Aluminum-ion batteries have similar functions to lithium batteries, but due to the difference in composition and structure, the level of electrical energy output is different. The aluminum ion battery can be fully charged in a short time and can be recharged 7500 times. Aluminum has low cost, low flammability, and high charge storage capacity, so it has always been an attractive material for batteries. The characteristics of aluminum ion batteries Aluminum ion batteries are highly efficient and durable, ultra-fast charging, high safety, foldable, low material cost, flexibility and long life. In fact, aluminum-ion batteries have long been considered by people to have a certain future in research, because of the great potential for energy density. But so far, the aluminum battery has only been used as a metal fuel power battery, not charging, but replacing the aluminum electrode to supplement the electricity. This is what the aluminum battery car that ran hundreds of kilometers said in the previous paragraph. Lithium battery: Lithium battery is a kind of secondary battery, it mainly depends on the movement of lithium ions between the positive electrode and the negative electrode to work. During 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, the negative electrode is in a lithium-rich state; the opposite is true during discharge. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium batteries. Lithium metal batteries are usually non-rechargeable and contain metallic lithium. Lithium batteries do not contain metallic lithium and are rechargeable. The characteristics of lithium batteries 1. The voltage is high, and the working voltage of the single battery is as high as 3.6-3.9V, which is 3 times that of Ni-Cd and Ni-H batteries; 2. The specific energy is large, and the actual specific energy that can be achieved at present is 100- 125Wh/kg and 240-300Wh/L, with the development of technology in the future, the specific energy can be as high as 150Wh/kg and 400Wh/L; 3. Long cycle life, generally can reach more than 500 times, or even more than 1000 times. About small current Discharged electrical appliances, the battery life will double the competitiveness of electrical appliances; 4. Good safety performance, no pollution, no memory effect; 5. Low self-discharge, self-discharge after fully charged Li-ion stored for 1 month at room temperature The rate is about 10%, which is much lower than 25-30% of Ni-Cd, 30-35% of Ni and MH; 6. It can be charged and discharged quickly, and the capacity of 1C charging can reach more than 80% of the nominal capacity; 7. The working temperature range is high, the working temperature is -25~45C. With the improvement of electrolyte and positive electrode, it is expected to be expanded to -40~70C. In recent years, the application range of lithium batteries has become wider and wider. Lithium batteries are widely used in energy storage power systems such as water power, thermal power, wind power and solar power stations, as well as electric tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, and aviation. Aerospace and other fields. At present, lithium batteries have gradually expanded to the fields of electric bicycles and electric vehicles.
