At present, lithium ion battery is the most popular solution for mobile power supply. However, in some applications, it has reached its limits. This is particularly applicable to electric vehicles, which require a wide range of lightweight compact vehicles. Lithium metal batteries may be another option. They are characterized by high energy density, which means that they store a large amount of energy per mass or volume. However, stability is still a problem because electrode materials react with traditional electr

With the development of electric vehicles, people pay more and more attention to a problem - whether the battery of electric vehicles is safe. Many forum users are discussing this issue. DEKRA Company plans to conduct a series of tests on electric vehicle batteries. During the test, three important electric vehicle batteries in the market will be tested to make the batteries burn and then extinguish them with different emergency extinguishing methods. Markus Egelhaaf, the head of DEKRA accident research team, sa

The progress of mobile devices and electric vehicles is driving the battery technology to obtain new breakthroughs, because only new progress in battery design can meet the energy demand of today's world. From handheld tools to computers and mobile phones, uninterruptible power supplies to satellites, batteries have always been a key design feature of everything. For many years, battery research has been carried out to improve energy density. During the rise of handheld devices, people needed higher energy d

The US Department of Energy approved a US $6 million fund for Ford Motor Company and Los Alamos National Laboratory to accelerate the development of hydrogen fuel cell technology. Debbie Dingell, the representative of D-Dearborn in the United States, jointly announced the approval of the grant on Thursday. Dingell said in a statement: "Ford Motor Company will help lead the research and development of the next generation technology in the United States, making American vehicles cleaner, safer and more fuel-e

At present, in the application of all electric or hybrid electric vehicles, the management of high voltage lithium-ion battery packs faces many challenges. In addition to monitoring the charging and discharging cycles, based on safety considerations, it is also necessary to isolate the battery packs that supply hundreds of volts. This paper discusses the monitoring needs of lithium-ion batteries, and discusses the architecture and components used in battery monitoring systems, digital communication systems and isol

Recently, South Korean researchers found that the performance of lithium air battery is closely related to the content of carbon dioxide. Related papers have been published in the Journal of the American Chemical Society. Researchers believe that Li2CO3 in the battery can be selectively used as the final product of the discharge reaction according to the dielectric properties of the electrolyte in the lithium air battery. In addition, they also verified that Li2CO3 can react reversibly in the lithium oxygen/carbon

In the 1980s and 1990s, people's communication basically depended on letters, telegrams and telephones. Among them, telephones were mainly landlines. If anyone installed a landline, they would immediately become the envy of the left and right. However, with the continuous development of science and technology, the landline phone was gradually replaced by the mobile phone. At that time, the most impressive thing was the "Big Brother", because it was the pioneer of mobile communication and the symbol of

Recently, American media reported that an American battery company named Sakti3 has successfully developed a new type of battery with energy density twice that of the existing lithium ion battery, and said it would like to cooperate with Tesla. As for Tesla, which wants to build its own battery factory, what will it do with this proposal and whether it will be included in its own supply system? Today, we might as well talk about this topic. ● Who is Sakti3? Sakti3 is an unknown small company for most people,

Recently, the National Development and Reform Commission and the National Energy Administration issued the Action Plan for Energy Technology Revolution and Innovation (2016-2030) within the system, and simultaneously released the Roadmap for Key Innovation Actions in Energy Technology Revolution, proposing 15 key innovation tasks, including innovation in clean and efficient utilization of coal, advanced nuclear energy technology, hydrogen energy and fuel power cell technology, advanced energy storage technology Ene
