Analyze the development of lithium-ion battery energy storage technology

my country’s largest battery energy storage project, lithium-ion battery re-spring, according to relevant media reports, recently, the Jiangsu Zhenjiang Power Grid Energy Storage Power Station project was officially connected to the grid. The energy storage power station uses lithium iron phosphate batteries as the energy storage unit, with a total capacity of 202,000 KWH and a total power of 101,000 kW. It is currently the largest battery energy storage power station in China. The operation of this project is of great significance to the lithium-ion battery industry. If it can form a demonstration effect, it can alleviate the current predicament of the lithium-ion battery industry to a certain extent. Since February 12, the bluff of the new energy vehicle subsidy standard has declined, the subsidy has been increased from 3 to 5 steps, and the subsidy threshold has been increased from a range of 100 kilometers to 150 kilometers, basically following the principle of a longer range of higher subsidy standards, because of subsidies Standard adjustments are fast, and many production of lithium-ion batteries have a low energy density transition. At the same time, with the domestic lithium-ion battery industry in recent years, the price of lithium-ion batteries related to materials has been average. Under the background of substantial decline in subsidies, the price of materials has doubled. The performance of lithium-ion battery companies has basically experienced a sharp decline this year. In addition to power lithium batteries, lithium ion batteries are used as energy storage batteries. Power lithium batteries have a higher price. Compared with power lithium batteries, the requirements for battery storage energy density are not high, but the safety and life requirements of the battery are very high, such as Lithium iron phosphate batteries, due to their low energy density, have gradually replaced ternary lithium ion batteries in the field of power lithium batteries, and the safety of lithium iron phosphate batteries is very good. Most energy storage power stations choose lithium iron phosphate. Ion batteries are used as energy storage batteries. In fact, this is because of the safe ferrous phosphate lithium-ion batteries. BYD has always been the battery of choice for new energy vehicles. This is why the emphasis is on long-term. BYD’s lithium-ion battery production has exceeded the Ningde era. , Using high-energy density lithium-ion batteries. However, lithium-ion battery energy storage power stations are commonly used in new energy power stations, and relatively few applications are used in traditional power stations. Due to the unstable voltage and the uncertain time of wind power and solar power generation, the use of energy storage power stations as power relays is more conducive to healthy grid operation. Some solar energy companies also have solar power generation and energy storage power stations combined into one product for sale, and the difficulty of customer deployment is reduced. In recent years, with the rapid development of the lithium-ion battery industry, the construction of lithium-ion battery energy storage power stations in traditional power stations has become a craze. Compared with pumped storage power stations, battery energy storage power stations are more flexible and occupy less area. It can be arranged quickly everywhere. In the entire domestic lithium-ion battery industry, high-energy-density battery technology is still relatively weak.In the Ningde era, for example, the company developed a ternary lithium-ion battery with an energy density of 240wh/kg, but the energy density of Tesla's power lithium battery supplied by Panasonic can be Up to 300wh/kg, the cobalt content of Panasonic battery production is low, which has an impact on the environment. The Ningde era can basically represent the highest level of lithium-ion battery technology in my country, and the lithium-ion battery products of other manufacturers may not be as good as the Ningde era. Under the premise of relatively oversupply of low-energy density batteries, the appropriate development of lithium-ion battery energy storage technology is expected to make the lithium-ion battery industry more healthy.
