The working principle of the new lithium battery

In the future, mobile phones may only be half thin and light, and no longer need to be charged daily. Even if the battery cost of electric vehicles is high, the short battery journey will be solved, because the international first of the new dual-ion battery technology was born in Shenzhen. Tang Yongbing, a researcher at the Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences, learned of this technology from Germany on March 29 and published their findings in the leading international journal Advanced Energy Data. Now the cost of choosing lithium batteries is relatively high, and waste batteries will pose a serious environmental problem, especially the power lithium-ion batteries of new energy vehicles have cost and battery life. However, Tang Yongbing's team discovered a new type of high-energy density aluminum-graphite dual-ion battery technology, which can process a new type of high-efficiency and low-cost energy storage battery. The new battery adjusts the positive and negative electrodes of traditional lithium batteries and replaces the negative data of cobalt lithium, manganese lithium, ternary or lithium iron phosphate that are currently widely used in lithium batteries, and replaces it with cheap and easily available graphite. Use aluminum foil as anode data and anode collecting liquid. The electrolyte is composed of traditional lithium salt and carbonate organic solvents. The working principle of this kind of battery is different from the traditional lithium battery. During the charging process, the anode graphite reacts with the negative ion intercalation, and the anode aluminum reacts with the aluminum-lithium alloy, and the discharge process is reversed. This new response mechanism not only significantly increases the working voltage of the battery (3.8-4.6v), but also significantly reduces the quality, volume and manufacturing cost of the battery, thereby comprehensively increasing the energy density of the entire battery.
