On March 5, four Japanese companies, including NGKINSULATORS and TOTO, announced the establishment of joint ventures on March 4 to promote the research and development of "solid oxide fuel cells (SOFCs)" that generate electricity by reacting oxygen in the air with hydrogen and other fuels. All companies will share relevant technologies previously promoted independently to promote practicality. This is the first time that four companies of "Sencun Group" have participated in joint business. Th

As a clean secondary energy, the wide application of hydrogen energy will become an important factor affecting economic development and inject fresh blood into industrialization. Countries with leading hydrogen energy technologies in the world, such as the United States, Canada, Germany and Japan, have studied their fuel cell and hydrogen energy industry chain technologies for more than 20 years. The hydrogen energy industry system, core components and materials have all had the basis for mass production, and their

According to the Japanese Economic News recently, Sanyo Chemical Industry and start-ups from Keio University are actively researching and developing. The "all resin battery", which uses resin to replace metal as a battery component to avoid fire, is expected to start mass production as early as the autumn of 2021. In this way, we will catch up with all solid state batteries and air batteries that are currently leading in the research and development competition of new generation batteries.(Lithium - Ion B

February 18 is the National Battery Day in the United States. Many Americans will replace their old batteries at home on this day and send them to the recycling center. To celebrate this unofficial festival, the US Department of Energy recently announced that the construction of the battery recycling research and development center of Argonne National Laboratory was officially launched, and the lithium ion battery recycling award project was launched to promote the recycling of key materials in lithium based batter

We will hear such remarks for a long time. The battery in Japan is good, but the battery in China is poor. The important point here is the consistency between battery cells. For vehicle endurance, capacity is the most direct and important parameter, so consistency mainly refers to capacity. Capacity is a parameter that cannot be directly measured in a short time. According to experience, it is found that the capacity of a single electric core has a one-to-one relationship with its open circuit voltage. Therefore, t

1 Application scenario of large-scale energy storage system In order to stabilize the fluctuation of output power, more and more new energy power plants, wind power plants or solar power plants are equipped with energy storage systems. With the reform of the electric power system, independent energy storage power stations have gradually entered people's vision, and independent energy storage power stations that make a living by reselling electricity have gradually emerged.(Lithium - Ion Battery Equipment)

The level of battery energy density is becoming an important factor determining the direction of subsidies for new energy vehicles. The subsidy of "low price retreat and high price rise" has promoted the upgrading of batteries and their materials. The ternary high nickel materials with high energy density and relatively stable price have become the best choice for battery enterprises. Ternary materials are gradually evolving towards high nickel. Many battery enterprises, such as Shenli Battery, Bike Batte

Despite the "cheat compensation" storm, the support of the decision-making level for new energy vehicles has not decreased. The recently held executive meeting of the State Council has determined five major measures to further support the new energy vehicle industry, including requiring central state organs, government departments and public institutions in cities where new energy vehicles are promoted to be used to increase the proportion of new energy vehicles purchased in the total number of vehicles e

Lithium ion battery is a complex system, including positive pole, negative pole, diaphragm, electrolyte, collector, binder, conductive agent, etc. The reactions involved include the electrochemical reaction of positive and negative poles, lithium ion conduction and electronic conduction, as well as the diffusion of heat. Therefore, the electrical performance and safety of lithium ion battery are affected by many factors. Therefore, the design and manufacture of lithium ion battery not only requires rich electrochem
