Although lithium-ion batteries have become the mainstream of energy storage today, the molecular and atomic basic science of their charge and discharge is still a mystery. According to the "NatureCatalysis" study by the U.S. Department of Energy's Argonne National Laboratory, the research team has made a breakthrough in obtaining the chemical composition of the solid-electrolyteinterphase (SEI) between the electrode and the liquid electrolyte. This will help improve the team's ability to predic
So far, for different fields and different needs, people have proposed and developed a variety of energy storage technologies to meet the application. Global energy storage technologies mainly include physical energy storage, chemical energy storage (such as sodium-sulfur batteries, all-vanadium flow batteries, lead-acid batteries, lithium-ion batteries, supercapacitors, etc.), electromagnetic energy storage and phase change energy storage. 1. Physical energy storage Physical energy storage technologies mainl
In recent years, my country's new energy vehicle industry has developed rapidly and has now become one of the world's leading industries in my country. According to the data of the Ministry of Industry and Information Technology, in 2017, the production and sales volume of new energy vehicles in my country reached 794,000 and 777,000 respectively, and the cumulative number of vehicles reached 1.8 million, accounting for more than 50% of the global market, ranking first in the world for three consecutive yea
From April 17th to 18th, the 7th Seminar on Recycling and Recycling of Automobile Power Batteries and Recycling and Regeneration of Secondary Batteries was held in Beijing. The key crux of power battery recycling Huang Jianzhong, former deputy inspector of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology and Secretary General of China Electronics Energy Conservation Technology Association, said: The current power battery recycling indus
According to foreign media reports, batteries have been integrated into our daily lives. Electric vehicles, flashlights, and remote controls seem to have long been inseparable from batteries in our lives. Fortunately, the battery of the future is developing in a sustainable direction. The editor has compiled five examples of innovative battery technologies in the future for readers to appreciate, as follows: 1. New battery powered by human skin Today, "smartwearables" such as smartwatches, Bluetooth
On the premise of ensuring safety, improving energy density, reducing production costs, and improving product consistency are topics of widespread concern in the power battery industry. The production cost curve is constantly fluctuating, and product consistency is not easy to quantify. To evaluate the technical level of power battery companies, comparing the energy density of cells is the most intuitive method. This article takes the ternary battery as an example, according to the three packaging systems of squ
From the cell phone in your pocket to the car on the road, almost everything with an electrical circuit requires a battery. While the rest of the tech industry has grown rapidly over the past few decades, batteries have made slow progress. In today's transportation, energy, infrastructure and other fields, insufficient battery has become the biggest bottleneck. Our energy needs continue to grow, but the amount of energy we can carry and store is limited. Smartphones struggle to last a day, electric cars have
In recent years, with the rapid development of the new energy industry and the continuous upgrading of the new energy vehicle and power battery industries, battery factories have higher and higher requirements for automation and compatibility. From December 27th to 28th, the "2017 APEC New Energy Vehicle & Lithium Battery Leaders Summit and the 3rd Qidian Golden Tripod Award Ceremony" hosted by Qidian Research, Lithium Battery Big Data and Qidian Electric Network was held in the Julong Hall of the
Difficulties and development directions of lithium titanate battery technology development 1. Reasons for developing lithium titanate battery technology in China The competition of lithium titanate battery technology in various energy storage batteries in our country should have the advantages of timing, location, and people. In terms of service life, the ultra-long cycle life of lithium titanate battery is far better than that of various lead-acid batteries; its efficiency, cost and electrochemical performan
