What are the uses of battery aluminum foil in batteries?

What is the purpose of aluminum foil in batteries? What is the purpose of aluminum foil in batteries? Battery aluminum foil is used as the collector of lithium batteries. In the operation of lithium batteries, rolled aluminum foil is generally used as the positive electrode collector. Active collector fluid lithium battery is a secondary battery system with two different intercalation lithium compounds, which act as the positive and negative electrodes of the battery, and can reversibly insert and discharge lithium ions. During charging, lithium ions are released from the positive electrode data lattice, and inserted into the negative electrode data lattice after passing through the electrolyte, making the negative electrode extremely rich in lithium and the positive electrode extremely depleted in lithium. During the discharge process, lithium ions are released from the crystal lattice of the negative electrode data, and inserted into the crystal lattice of the positive electrode data after passing through the electrolyte, making the positive electrode extremely rich in lithium and the negative electrode extremely depleted in lithium. In this way, the difference between the positive and negative data on the potential of lithium ions in and out of lithium metal is the operating voltage of the battery. Lithium battery cathode data Lithium battery is a new generation of green energy batteries with outstanding functions, and has become one of the focuses of high-tech development. Lithium batteries have the characteristics of high voltage, large capacity, low power consumption, no recall effect, no pollution, small size, small internal resistance, less self-discharge, and more cycles. Because of these characteristics, lithium batteries have been used in many civilian and military fields such as mobile phones, notebook computers, camcorders, and digital cameras. The important composition data of lithium batteries include electrolyte, barrier data, positive and negative data, etc. The positive data accounts for a large proportion (the mass ratio of positive and negative data is 3:1~4:1), because the function of the positive data directly affects the function of the lithium battery, and its cost directly determines the cost of the battery. The new technology of monotonization and calcination of lithium battery cathode data uses microwave monolithic new technology to process monolithic lithium battery positive data, and monolithic processing of conventional lithium battery positive data, so that capital turnover is slow, and the monolith is uneven and monolithic The detailed features of the low depth are: the use of lithium battery anode data microwave monolithic equipment, which is convenient and fast. It only takes a few minutes to finish the monolithic depth, and the moisture content can reach more than one thousandth. Using microwave single lithium battery negative data, The single time is uniform, and the product quality is good in a single time. Using microwave single-shot lithium battery cathode data, it is highly efficient, energy-saving, safe and environmentally friendly. Using the positive data of the microwave unipolar battery, there is no thermal inertia, and the instantaneity of heating is easy to control. The application of electroplating film technology has led to the emergence of thin-film printed batteries. Conductive coatings introduce nanotechnology into battery products and play a vital role in the development of lithium battery products. In high-speed mobile computing products, lithium batteries undoubtedly play a very important role. At this time, the demand for energy-saving products is rapidly increasing, and the need for rational use of electricity, that is, energy-saving, is also increasingly urgent. In this context, conductive coatings and shopping malls will become more important and have more potential. The electrocoating film can pass through electrical contact, thereby reducing internal resistance and stroke rate, improving discharge efficiency and prolonging cycle life. This coating is like a conductive gasket embedded in the battery, ensuring that the electrical connection to the touch interface is sealed. In addition, the coating can also provide a chemical barrier for the solid battery to keep the battery from oxidation or chemical corrosion, and also to end the self-discharge, heat dissipation and leakage, plus the extension of the service life of the power equipment. The use of conductive coatings in batteries not only maintains excellent electrical conductivity, but also chooses low-cost uncoated light metals as raw materials for battery processing, which significantly reduces the weight and price of battery products.
