Is 18650 battery lithium ion 2200mah technology more mature than lithium-ion battery technology?

　　Is 18650 battery lithium ion 2200mah technology more mature than lithium-ion battery technology? In recent years, graphene, a Nobel Prize-winning material, has been attracting widespread public attention, and relevant media has been full of news about various “graphene batteries” and other aspects. Every product on the market has to go through a long process from research and development to launch, such as safety, stability, practicality, and cost-effectiveness. Only with these properties can it become a product that meets the needs of consumers. . People can't help but wonder: Is 18650 battery lithium ion 2200mah technology and manufacturing art more mature than lithium-ion batteries? Can it be relied upon to solve a series of technical bottlenecks currently encountered in materials, batteries, etc., and help industries such as electric vehicles and energy storage achieve a leap forward?

　　18650 battery lithium ion 2200mah technology manufacturing process technology

　　1. The weather deposition method mainly uses carbon-containing gas (methane, methane). Under certain temperature and pressure conditions, carbon atoms adhere to the growth base to form a single layer of carbon structure material and gradually grow.

　　Advantages: The resulting graphene has a good structure and its size is not limited by the raw materials. Disadvantages: The preparation process is complex and the production efficiency is low.

　　2. The redox method uses an oxidant to oxidize graphite layer by layer, and uses ultrasound and other methods to peel off the oxidized layers. Afterwards, the graphite oxide layer is reduced using a reducing agent to obtain graphene.

　　Advantages: low cost and high production efficiency. Disadvantages: The size of the graphene produced is determined by the raw materials, and the oxidants and reducing agents used may pollute the environment.

　　3. The intercalation method is to fill the interlayer gaps of graphite with intercalation substances, thereby overcoming the van der Waals force between layers, causing each layer to disperse, thereby obtaining graphene. This method is still in the research and development stage.

　　Graphene batteries cannot currently replace lithium batteries

　　The so-called 18650 battery lithium ion 2200mah is actually not a new technology and has been in the research and development stage in recent years. It should be said that its materials and processes are not yet fully mature, and many of the reports we see are only scientific research reports, not product reports. There are reports that some mobile phones use graphene batteries, but this is actually a misinformation.

　　At this stage, this technology mainly has two major problems: cost and production capacity. The ideal 18650 battery lithium ion 2200mah has extremely powerful performance, extremely fast charging, and extremely long life, but the cost is also extremely high. Most current research is addressing cost issues by combining graphene with other materials to create batteries. In fact, it is more appropriate to become a graphene-based battery, and quite a few of these types of batteries are still essentially the lithium batteries we are familiar with and have not been completely innovative.

　　Although in theory, graphene can be used as a conductive agent to increase the speed of charge and discharge, but if the power dispersion is not in place, the performance will not only fail to improve, but will also decrease. Coupled with the complexity of the production process, the cost is higher. Compared with traditional lithium batteries, they are not suitable for large-scale introduction into the market.

　　First of all, the cost of graphene batteries is extremely high. As a raw material, highly conductive graphene currently sells for up to 600 yuan per gram. Graphene batteries, known as "black gold", are mostly used in special aerospace and mobile equipment fields. People-friendly electric The car can only look forward to it and sigh.

　　Secondly, the manufacturing process of graphene batteries is still not mature enough. It is currently only in the laboratory stage and cannot reach mass production. It will be difficult for graphene batteries to be put into the electric vehicle market in the short to medium term.

　　In addition, compared with graphene batteries, lithium batteries, which are the crystallization of battery development, still have many advantages. Both the market and technology are more complete. Graphene batteries are more likely to be integrated into lithium batteries with a new technology to promote the battery revolution. process.

　　Graphene batteries have bright future

　　In view of the excellent performance and huge application prospects of graphene, governments and enterprises in various countries have invested a lot of manpower, material and financial resources in research on graphene. Perhaps in order to continue to attract attention and investment, companies often claim that they have made very powerful graphene products. In my opinion, these are just noises from reality.

　　But it is precisely amid this hustle and bustle and huge investment that graphene research has indeed achieved many good results. The price of graphene has been slowly decreasing, and larger-sized and higher-quality graphene has been gradually successfully developed. The downstream industry chain is also gradually trying to use graphene.

　　In terms of technology maturity and urgency of demand, its application in lithium-ion batteries to improve battery charging and discharging efficiency, battery capacity and battery stability obviously plays a decisive role in the development of automobiles, especially electric vehicles. For electric cars to become mainstream, graphene is crucial. If driverless and solar-powered cars are also taken into account, graphene will undoubtedly have a broader application space in the automotive field.

　　If graphene wants to surpass lithium batteries one day, it must show greater advantages than aluminum batteries in the laboratory. But for now, graphene batteries are still very immature and have not shown any major advantages over lithium batteries, so the era when lithium batteries will be replaced may not come so early.

　　However, I believe that as research continues to deepen, one day in the future, graphene’s singularity will come, and many industries will undergo earth-shaking changes and even be subverted.
