There is still a long way to go from successful R & D to mass production.
Recently, according to foreign media reports, Australian researchers have developed what is said to be the most efficient lithium-sulfur battery in the world. Compared with similar batteries on the market, the performance of this battery may be more than four times higher.
It is understood that Dr. Mahdokht Shaibani of Monash University has led an international research team to develop a large-capacity Li-S battery that can power smartphones for 5 consecutive days or allow electric vehicles to travel more than 1,000 kilometers without recharging. Compared with current lithium-ion products, this battery has better performance and less impact on the environment.
Associate professor Matthew Hill who participated in the research said that the performance of the battery is very attractive. If the battery is produced in a manner with low manufacturing cost, sufficient material supply and low impact on environmental pollution, then this battery will be There is great value in the entire commercial market.
The Monash University team in Melbourne has published the research paper in the "Science Progress" magazine, and the work of the research team has been funded by the Australian government. It has also applied for a patent for the lithium-sulfur battery they developed. The battery technology will be further tested later this year.
At present, the German R & D partner Fraunhofer Institute for Materials and Beam Technology, which cooperates with the team, has successfully manufactured prototype batteries. very interested. Researchers on the team said they are now on the "edge" of commercializing innovation.
Currently, battery technology is still one of the core technologies of new energy vehicles. The research and development of high-performance batteries has been carried out in enterprises and major universities. At present, the research direction is mainly divided into several categories: one is the graphene battery that Huawei and Samsung are continuously developing; the other is the nickel developed by Tesla and the Jeff Darn research team of Darn Dalhousie University. Cobalt manganese battery.
Among them, Huawei demonstrated the graphene battery in 2016, and also cooperated with the University of Manchester to study the application of graphene, that is, the breakthrough results in the field of graphene will be applied to consumer electronics and mobile communications equipment.
However, there is still a long way to go from successful R & D to mass production. On November 27, 2017, Samsung also announced that it has developed a new battery technology based on graphene materials, which can increase the charging speed by 5 times and increase the battery capacity by 45%. However, this graphene battery has not been used in any Samsung devices. application. (Author: Terence Lee Nan)
Carbon crystal is a kind of modified purification of carbon particle heating product,which the short carbon fiber is modified by ball milling processing,and made into microcrystalline particles, then add far infrared emission agent, with special craft synthetic made heating element. High quality carbon particles can generate heat more evenly,more efficient.
By continually practiced and compared,we have applied most advance infrared heating technology to improve the quality of our panel heaters.
