Compared with traditional liquid lithium batteries, solid-state lithium batteries (SSLB) use solid electrolytes instead of organic electrolytes. Their safety and energy density are greatly improved, which can effectively reduce safety hazards of electric vehicles and relieve users' range anxiety. Solid electrolyte, as an electronic insulator and ionic conductor, is one of the core elements of SSLB. At the same time, it has problems such as low ionic conductivity, large interface impedance, and poor interface st

[Phenomena] From mobile phones, computers, wearable devices, to new energy vehicles and electric bicycles, lithium batteries are widely used. While market demand is increasingly strong, lithium batteries themselves also have shortcomings such as high production costs and low reserves of key raw materials, which has forced some companies to accelerate the search for alternative technologies and turn their attention to new batteries such as magnesium, zinc, and sodium. Some media pointed out that the global race arou

Global lithium resources are widely distributed, but reserves are limited. At present, they are mainly concentrated in South America, my country, and some places in Africa. my country's lithium resources are concentrated in salt lakes and ores. About 70% of the currently proven reserves are concentrated in the salt lakes of Qinghai, and some are scattered in mines. Due to their different natural endowments, these two resources have differences in later mining, extraction, production technology and product quali

The third exchange meeting on the special topic "Power Lithium Battery Technology Upgrading and Industrial Chain Research" organized by the my country Electric Vehicle 100 People's Association was held at the Tsinghua Unigroup International Exchange Center. More than 60 guests from universities, research institutes, and companies gathered around " "Power lithium battery design, technology and equipment" will be discussed.

Bipolar all-solid-state lithium batteries (LIB) have attracted considerable attention as a solution to rising energy and safety demands. However, the use of inorganic solid electrolytes (sulfides or oxides), which are the most widely studied electrolytes in LIBs, in addition to long-standing problems such as chemical/electrochemical instability, interfacial contact resistance and manufacturing processability, will also cause Causes problems with mechanical flexibility and form factor. [Background introduction]

Researchers at Chalmers Institute of Technology in Sweden have discovered that graphene could become lethal to bacteria, killing them and preventing bacterial infections during implant surgeries. Let’s follow the embedded editor to learn about the relevant content. Implant surgeries such as joint replacements and dental implants have been increasing in recent years. This type of treatment usually carries the risk of bacterial infection. In severe cases, the implant cannot connect to the bone and has to be

According to foreign media reports, researchers have designed a new lithium battery that may have five times more power than current lithium batteries. The design uses lithium to react with oxygen extracted from the air to reduce the weight of the lithium battery. It may be used in mobile phones, laptops and electric vehicles in the future, and may even extend the cruising range of electric vehicles. The research team was led by Amin Salehi-Khojin of the University of Illinois and Larry Curtiss of Argonne Nation

Gel battery is also a type of lead-acid battery. It is an improvement on ordinary lead-acid batteries with liquid electrolytes. Colloidal electrolyte is used instead of sulfuric acid electrolyte, thereby improving safety, power storage, discharge performance and service life. At present, gel batteries are widely used in power generation, communications, automobiles, emergency lighting and other fields. Why is it so popular? Let’s analyze the technical principles of gel batteries and unveil their popularity.
