Lithium-ion battery is expected to become the cheapest power storage option

According to the recent news from the American 'Joule' magazine, Imperial College of the United Kingdom released a new model prediction, the results show that in the next few decades, lithium-ion batteries are expected to become the cheapest choice for power storage in most application scenarios. . In the 1990s, researchers at Sony Corporation in Japan inserted lithium ions into carbon (petroleum coke and graphite) to form a negative electrode, and successfully developed a lithium-ion battery. At that time, traditional lithium batteries used lithium or lithium alloy as the negative electrode. As a kind of secondary battery (rechargeable battery), lithium ion battery mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. Lithium ions are embedded in carbon, which not only overcomes the high activity of lithium, but also solves the existence of traditional lithium batteries. Security issues. The lead author of the latest research report, Imperial College scientist Oliver Schmidt believes that in the future, lithium-ion batteries will have an advantage in most power system applications due to their low cost and superior performance. Schmidt and his research team established a model to analyze the cost trend of 9 power storage technologies, including large batteries and pumped storage power stations, in 12 application scenarios from 2015 to 2050. The research results show that the current cheapest way to store electricity is pumped-storage power stations, which use excess electricity when the power load is low to pump water to the upper reservoir, and then release water to the lower reservoir to generate electricity when needed. But according to model predictions, as time goes by, the cost of pumped storage power stations will not drop further, while the cost of lithium-ion batteries will continue to drop. According to the study, it is expected that from 2030, lithium-ion batteries will become the cheapest power storage option, and this conclusion is applicable to most application scenarios. By 2050, the cost advantage of lithium-ion batteries will be more obvious. Since the birth of lithium-ion batteries in the 1990s, they have increasingly become an indispensable existence in ordinary people's lives. From mobile phones that stay in the air every day, to consumer drones flying in the sky, to electric cars running on the road, lithium-ion batteries are the energy heroes that drive them. Undoubtedly, lithium-ion batteries will continue to be proud of their outstanding performance in power storage for some time to come. However, new technological revolutions are surging, and once there is a breakthrough in the new energy storage technology, it is not impossible that Cheng Yaojin halfway through.
