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.

The improvement of battery life determines the fate of electric vehicles. Scientific researchers are pursuing new discoveries in chemistry and materials, and car companies and battery suppliers are working together to reduce costs and add energy. Among the emerging new technologies, a lot of research has been invested in replacing lithium-ion chemistries, and some have become popular applications and solutions. 1.

Factors affecting the fast charging capability of lithium-ion batteries are analyzed from the perspective of battery structure. Under different state parameters and environmental parameters, the charging current value of each lithium-ion battery is optimal. So, from the perspective of battery structure, what are the factors that affect the optimal charging value? Microscopic charging process Lithium-ion batteries are known as rocking chair batteries, in which charged ions move between the positive and nega

According to foreign media reports, researchers at Virginia Tech in the United States have demonstrated a green and sustainable lithium battery (LIB) manufacturing method that does not use harmful organic solvents in the battery electrode production and recycling process. (: Virginia Tech) The researchers found that the rate performance and cycle life of electrodes fabricated through a water-based process were comparable to electrodes fabricated using traditional solvent-based processes. The use of water-solu
