Analysis of breakthroughs in energy density of power batteries

　　At present, many domestic power battery manufacturers have launched power battery products with a weight energy density of more than 300Wh/kg to meet the increasing cruising range of electric vehicles. The demand for high energy density power batteries, but lithium-ion based on liquid electrolyte Battery energy density is about to hit the ceiling. It is currently generally believed that the upper limit of energy density of the existing lithium-ion battery system is 350Wh/kg. To further improve the energy density of the battery, a new system needs to be adopted. Judging from the existing technology , all-solid-state battery technology based on solid-state electrolytes is the most promising next-generation battery technology candidate. 02 Thermal Battery Australia launches the world's first thermal battery for energy storage: with a lifespan of 20 years and a cost eight times lower than that of lithium batteries. In order to improve the stability of power consumption, South Australia is committed to installing various grid-level energy storage systems, ranging from lithium-ion battery energy storage systems, pumped hydropower stations and compressed air energy storage plants, covering almost everything. Now South Australia may have a new energy storage force. Local energy technology company CCTEnergyStorage claims to have created the world's first usable thermal battery. In addition to It has a service life of 20 years and the cost is 60-80% lower than current lithium batteries. 03 Flywheel Energy Storage my country’s first flywheel energy storage system commercialization project with completely independent intellectual property rights was put into operation. Recently, the first (set) 100kW flywheel independently developed by Erzhong Deyang Energy Storage Technology Co., Ltd. (referred to as Erzhong Energy Storage Company) The energy storage uninterrupted power supply system has been installed and debugged in the data center of Erzhong (Deyang) Heavy Equipment Co., Ltd. and has been officially put into operation. 04Hydrogen hybrid battery The world’s first hydrogen hybrid battery ferry is about to be launched for testing. Recently, three companies, ABB, SINTEF and Fiskerstrand, collaborated in the HYBRIDship project to test the world’s first hydrogen hybrid ferry conversion for fuel cells. Hot New Vocabulary 01 Integrated Energy Services State Grid leaders said: Integrated energy services have a trillion-level market potential. It was learned at the Integrated Energy Services Seminar under the "Three Types, Two Networks, World-class" strategy held on April 9 that 2020~ In 2025, my country's comprehensive energy service industry will enter a period of rapid growth, with the market potential increasing from 0.5 to 0.6 trillion yuan to 0.8 to 1.2 trillion yuan; in 2035, it will enter a mature stage, with a market potential of 1.3 to 1.8 trillion yuan. The four major business layout ideas of integrated energy services. The most abstract understanding of the integrated energy service industry chain is from upstream standard formulation, to design planning, product manufacturing, engineering services, and then to downstream operations. Another understanding of the industrial chain links is the electricity production and supply chain, that is, "power generation, power transmission (transformation), power distribution, power consumption, dispatch (transaction)", in which the dispatch (transaction) link is relatively independent of. 02 Ubiquitous Power Internet of Things The Ubiquitous Power Internet of Things will drive power systems such as energy storage and distributed power supplies to form a huge industrial chain. The Ubiquitous Power Internet of Things will directly drive the development of sensors, power secondary equipment, and the information and communication (ICT) industry. More importantly, the ubiquitous power Internet of Things provides a secure and open data exchange, operation control and management platform that connects power equipment, power operators and users anytime and anywhere, and will promote distributed power generation, energy storage, electric vehicles, The development of new equipment, new businesses, and new business models such as smart home appliances, data analysis services, system operation and maintenance services, power system peaking auxiliary services, power trading services, and efficient comprehensive energy utilization will form a huge industrial chain around the power system. . 03BP World Energy Outlook 2019 "BP World Energy Outlook" is freshly released! Renewable energy accounts for about one-third of power generation. The world continues to be electrified, and power consumption is growing strongly. Under the gradual transformation scenario, about three-quarters of the increase in primary energy demand is used for power generation, and nearly half of the primary energy is absorbed by the power industry by 2040. Nearly all of the growth in electricity demand is coming from developing economies, especially China and India. Demand growth in the OECD was very small, reflecting slower economic growth in mature, advanced economies and the gradual decoupling of electricity demand from economic growth. Renewable energy accounts for about one-third of electricity generation and will account for about 30% of the global power generation industry by 2040. On the contrary, the proportion of coal power generation has decreased significantly, and as a primary energy source, it will be surpassed by renewable energy by 2040. New Bidding Plan 01 Energy Storage Frequency Modulation Guangdong Maoming Zhenneng Thermal Power AGC Energy Storage Auxiliary Frequency Modulation Project EPC Maoming Zhenneng Thermal Power Co., Ltd. coal-fired unit has an installed capacity of 1220MW+1330MW+1600MW. The 220MW unit was officially put into operation for power generation in June 2003, and the 330MW unit was officially put into operation for power generation in May 2007. The utility system of the unit was put into use with the commissioning of the 220MW unit; the 1600MW coal-fired unit was put into operation at the end of December 2013. The bidder also needs to conduct a feasibility study on connecting the energy storage frequency regulation device to the #5 unit. Please refer to the technical specifications for details. 02 Energy storage operation and maintenance Hunan Changsha Langli Energy Storage Power Station short-term operation and maintenance service bidding Changsha Battery Energy Storage Power Station Phase I Demonstration Project Langli Energy Storage Station short-term operation and maintenance services, including operation monitoring, inspection inspections, abnormal operation and fault handling, system Maintenance, equipment maintenance and other work content.
