Cobalt derivatives prices have rarely been stable this week. Entering mid-April, consumer electronics are still in the off-season, and the recovery process of power batteries is slower than expected. The weakness of the terminal finally has a certain inhibitory effect on the skyrocketing upstream. The trading price of cobalt derivatives was flat this week. In terms of lithium salts, SMM believes that there is still some room for decline in lithium carbonate in the second quarter, but the space is limited, mainly be

Recently, the Energy Storage Technology Research Department of the Dalian Institute of Chemistry, Chinese Academy of Sciences reported a new process for preparing flexible batteries. They achieved direct and firm bonding of active materials and conductive substrates through electroless plating technology. When the battery is arbitrarily bent, the active materials will not be generated. It falls off, showing good flexibility, and the battery can be applied to bendable electronic devices.(Lithium - Ion Battery Equipm

Each lithium battery has an optimal charging current value under different state parameters and environmental parameters. Then, from the perspective of battery structure, what are the factors that affect this optimal charging value. The microscopic process of charging Lithium batteries are known as "rocking chair" batteries, in which charged ions move between positive and negative electrodes to transfer charges to power external circuits or charge from an external power source. In the specific charg

The application of large-scale energy storage devices represented by smart grids puts forward higher requirements on the cycle life, power density, cost, and safety of energy storage batteries. The room temperature secondary magnesium-based battery is a kind of electrochemical energy storage system with metal magnesium as the negative electrode. cm3), no dendrite formation during electrochemical cycling, and the theoretical reduction potential of magnesium ions is only about 0.6 V higher than that of lithium ions.

When discussing charging speed, the endurance of the battery itself is definitely the most inescapable factor. No matter how powerful the peripheral charging equipment is, how powerful the power is, and how strong the charging capacity is, if the battery itself has shortcomings in the acceptable charging capacity, the charging speed will definitely not be faster. If the battery capacity is relatively large, the natural charging time will be longer. If you have studied electrochemistry in high school, you will un

As of 2017, the total number of new energy vehicles promoted in my country has exceeded 1.8 million, the energy density of power batteries has tripled compared to 2012, and the price per kilowatt-hour has dropped by more than 70%. Data show that in 2020, it is expected that China's domestic automotive power battery recycling will reach 257,000 tons, and this figure will reach 422,000 tons in 2022. With the rapid development of new energy vehicles, the decommissioning of power batteries in my country will gra

A research team from Hefei University of Technology has prepared a high-strength, self-supporting, ultra-thin and transparent graphene film and assembled it into an all-solid-state flexible supercapacitor, opening up a new path for the research and development of next-generation flexible electronic devices. The scientific research team of Professor Huai Ping of the school cooperated with the University of Science and Technology of China, Nanjing University, etc., and found the molecule with the strongest interac

According to foreign media reports, Faurecia participated in the Hannover Messe in Germany for the first time this year. The company will display fuel cell solutions at the exhibition to support the transformation of the automotive industry to zero-emission mobility solutions. Faurecia aims to optimize high-pressure fuel tanks to advance fuel cell technology and stacks for industrialization in the automotive industry. Faurecia devotes considerable technical experience to its system integration, integrating hydro

As an extremely important non-metallic mineral, its processed products are not only widely used in traditional industries such as iron and steel industry, but also in emerging industries such as new energy and new materials, and are considered to be an important strategic resource to support the future development of high-tech . The Chinese government attaches great importance to the protection, development and utilization of graphite resources. In November 2016, the National Mineral Resources Plan (2016-2020) appr
