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.

If new energy vehicles want to be truly close to the experience of traditional gasoline vehicles, shortening charging time, improving cruising range and charging convenience are unavoidable topics. Dr. Wang Shengwei, head of the fast charging project of CATL New Energy Technology Co., Ltd. (CATL), said that the "superconducting electronic network" and "fast ion ring" technologies developed by CATL are a perfect combination, and the lithium iron phosphate fast charging core has been developed int

The energy-saving and new energy vehicle technology roadmap announcement conference was held in Shanghai on the 26th. The roadmap was commissioned by the National Strategic Advisory Committee for Building a Manufacturing Power and the Ministry of Industry and Information Technology, and was researched and compiled by more than 500 industry experts organized by the my country Society of Automotive Engineering over a year. According to reports, this technology roadmap plans the development of my country's auto

When it comes to driving, safety comes first. As the most eye-catching newcomer, electric vehicles urgently need to improve themselves in the field of safety. The development of battery pack mechanics simulation models plays a key role in the development of collision safety of future electric vehicles. Research on the mechanical behavior of the component materials of lithium batteries aims to establish a basis for refined battery pack models. This article will introduce to you the relevant research of this research

In a narrow sense, ternary materials refer to stoichiometric nickel-cobalt-manganese three-component layered cathode materials. This type of material was first developed by Chinese scholar Liu Zhaolin in 1999 at the Institute of Materials Research and Engineering (IMRE) affiliated to A-Star in Singapore. ) was reported when I was working on it. Since then, many international research groups have conducted very detailed and in-depth research on this series of materials. In a broad sense, the scope of ternary mate

Recently, Zhang Yuegang's research group at the Suzhou Institute of Nanotechnology and Nanobionics, Chinese Academy of Sciences independently developed and designed an in-situ scanning/transmission electron microscope electrochemical chip, which enabled real-time observation of the charging process of lithium sulfide (Li2S) electrodes; in fully understanding Li2S charging Based on the discharge mechanism, a high-nitrogen-doped graphene-loaded lithium sulfide material was designed as the battery cathode. By cont

Since March, there have been 7 or 8 electric vehicle battery fire incidents in China, bringing the issues of battery safety and battery management system safety to the forefront. In these fire incidents, the temperature of the power lithium battery was uncontrollable and rose linearly after being heated, which led to combustion and explosion. This phenomenon has a professional term called thermal runaway of power lithium batteries. The rise in battery temperature is the culprit of fire and combustion, and the re
