Recently Escort manila, a Guangqi Group officially announced that its graphene battery mass production research and development task will move from the experiment room to the actual vehicle by the end of this year, once again focusing the industry’s attention on graphene batteries.
Introduction to Guangqi Group, the “super fast charging battery” developed based on Guangqi three-dimensional structure graphene (3DG) data can charge the battery to 85% in just 8 minutes, and the charging time is comparable to the refueling time of traditional fuel vehicles. In this regard, some people are praising the innovative technology of this battery, some are skeptical about 85% charging in 8 minutes, and some even say that this is another hype about graphene batteries.
So, where is the specific application value of graphene data in the power battery field? Regarding the next generation of power battery technology, which category is more optimistic about in the industry? Surrounded by these issues, Liss Motor launched a one-week online survey, attracting nearly 1,700 people to participate.
Graphene batteries do not change battery functions from the essence
Because they have super light, ultra-high strengthSugar baby, super-strong conductivity and other characteristics, graphene data was once considered the main technology to improve battery charging rate and promote the advancement of power battery technology. In 2010, graphene explorer Rong won the Nobel Physics Award. In 2017, the Ministry of Industry and Information Technology drafted the “New Special Plan for the 13th Five-Year Data Field Science and Technology Innovation”, which regarded graphene data technology as a key development field. To this end, many companies have started research and discussions on graphene data in terms of power batteries, but there has never been much breakthrough.
In the field of power batteries, what are the application conditions of graphene data? Nearly 46% of participants pointed out that “the gimmick is practical and not worth much”, and 38% of the participants are also saying that.net/”>Sugar baby said that “in theory, graphene can improve the charging and discharge speed, and it is actually waiting to be verified. daddy”.
The in-depth analysis of the Via Motor Research Institute pointed out that the application of graphene data does not change the battery function from the essence, and the important data system of this type of battery has not changed. The main reason is ternary, iron phosphate or primordial system, etc., which is mostly graphite or metal oxide. There are electrolytes and separators, but there are almost no real graphene batteries.
As an insider involved in data research, it is reported that the “graphene batteries” currently discussed in general refer to the storage of graphene data that is used for battery negatives, and the storage of electrochemical energy in the battery is still subject to steel ion migration, embedding or combining electrochemical energy. href=”https://philippines-sugar.net/”>Escort and skeletons are strictly speaking without the term “graphene battery”. The gimmick meaning is far from being large in practical value.
The demand points out that in the “super fast charging battery” released by the Guangzhou Auto Group this time, the href=”https://philippines-sugar.net/”>Pinay escort‘s specific application methods for graphene data are not introduced. In this regard, the industry has guessed that graphene should be more efficient or charged as an electric conductor, and its functions are better than others. daddy has done a little better.
Sugar babyMainly the cost and technology, the graphene battery “hard production” has led to the “difficult” development of graphene batteries. According to the planning of the Guangqi Group, its graphene battery production research and development tasks will move from the laboratory to the actual vehicle by the end of this year. AiSugar daddyon) car model will be the first to be launched. From the experiment room to the actual vehicle, what difficulties do graphene batteries need to occupy?
“This kid!” Jung Ju slammed helplessly, “Then go back, the research results show that “capital money” is the biggest resistance, followed by “technology”. 46% of the participants said that real graphene batteries are difficult to produce at large modulus. Importantly, graphene money is too expensive, and it is comparable to the data used in common steel batteries. Manila escortGraphene data is more than ten times more expensive in capital.
In addition, from a technical point of view, the reason why graphene batteries are “difficult” is to balance the fast charging and safety. Fast charging has always been one of the goals of power batteries, but for The operator who carries the safety of the lives of passengers. In terms of automobiles, in addition to fast charging, it also requires functions such as battery safety, efficiency and long life.
Today, the “super fast charging battery” of the Guangzhou Automobile Group has completed the testing tasks of cores, modules, and battery packs, and has installed the car with a large power<a For charging tests, it takes only 8 minutes to charge the battery to 85%. Can this fast charging battery, which is comparable to the fuel car refueling time, be balanced and meet the above functions. It is still a step further in the market to be realized. Things are indeed like a dream. baby—Ye Qiukan’s beekeeper failed, experienced.
Solid battery has become the first choice for the next generation of battery technology
In addition to Guangqi’s announcement of breakthrough in graphene batteries, Honeycomb Power, which has been independent from Changcheng Automobile, has recently launched the “unscaling-free battery” technique. In addition to the birth of Biadi blade batteries, domestic power battery sectors have been severely broken. The diversified Pinay escortBehind the technical routeEscort manila, who will be polite? Escort
In the question of “Which type do you prefer for the next generation of power battery technology”, solid-state batteries were selected with high tickets. More than 40% of participants said that solid-state batteries will be the ultimate goal of the development of next generation of power battery, Gao Xiao San Technical routes such as phosphate and iron phosphate are all transition plans. This result is incompatible with the predictions in the “New Power Automobile Power Battery Industry Report (2020 Edition)” recently released by the Lishi Automobile Research Institute.
Sugar daddy forecast analysis around 2020, battery data will evolve to 300px + silicon carbon to Sugar daddyThe important thing in 2025 is that the strongest data of Fujiji is broken, and in 2030, it is important to hope to break through the electrolysis quality and realize the full solid battery.
Euro Minggao, an academician of the Chinese Academy of Sciences, also publicly demonstrated that based on the comparison of the technical routes of power batteries in various countries, in the short term, the short term is Sugar daddy. daddy seems to be the ionic electrolyte of liquid electrolyte. It has developed high-voltage ternary electrodes and silicon carbon negative electrodes, and will slowly transition from liquid electrolyte to all solid-voltage batteries in the medium and long term.
“Solid-voltage batteries have become the ultimate goal of the development of the next generation of power batteries, and are inseparable from its unique functional advantages. “The above analyser shows. It is clear that the application of solid electrolysisThe quality solid battery has the advantages of non-ignition, non-corrosion, non-discharge, and no leakage, which can greatly ensure the safety of the battery. In addition, solid battery uses metal steel as a negative electrode, which can be matched with high voltage positive electrode data to further improve energy density.
However, solid batteries also face considerable challenges in the process of industrialization. First of all solid battery has some key technologies that need to be broken, such as the solid electrolysis data has a low electrical conductivity, and the contact area with the electrode data is small, which has a large impact on the charging rate. Secondly, how to find a balance between scale and capital is also the main problem that must be considered in the mass production jo TC:
