What are the advantages and disadvantages of graphene batteries

Graphene battery advantages 1. A wide range of applications, and a large number of them will be used in the mobile terminal, aerospace engineering, and new energy battery industries. 2. According to the advantages of high conductivity, high strength, ultra-light and thin, the advantages of graphene in the aerospace industry are also extremely clear. Not long ago, NASA of the United States of America developed and designed graphene temperature sensors that are used in the aerospace industry, which can very well test the nutritional elements in the high-altitude layers of the universe and the functional shortcomings of the space shuttle. Graphene will also fully mobilize more critical applications in potential applications such as ultralight aircraft materials. 3. Graphene is the most suitable material for electrical conductivity in the world today. Graphene is added to traditional mobile phone lithium batteries. The conductive performance powder of the ene composite material strengthens the battery’s rate of charge and discharge performance indicators and cyclic reciprocating application time; 4. It is safe, reliable and relatively stable. Its short-circuit failure, there is no chemical reaction; it is placed on a fire, and there will be no explosion accident; 5. When electrons transmit data in graphene, they will not easily cause electron scattering, and the electron density can reach 200,000 cm2/( V*s) is about one hundred and forty times the electron density in silicon, and its conductivity can reach 104S/m, which is the most suitable material for conducting electricity at indoor temperature. 6. The application time limit is 4 times that of traditional nickel-hydrogen batteries and twice that of lithium batteries. 7. The charging efficiency is high, and its total weight is about only a part of traditional batteries. In terms of charging rate. Graphene batteries can be enhanced to a higher level in performance. Disadvantages of graphene batteries 1. There are still problems with the process itself, and it is not night. Compatibility issues, the graphene specific surface area is too large, which will cause chaotic process problems such as the dispersion and homogenization of the existing lithium battery; 2. The graphene battery on the market is not a pure graphene battery, but a lithium battery On the basis of a part of graphene-related technologies, compared with traditional lithium batteries, the performance indicators that it has caused are only a little bit stronger. In addition, the cost of graphene is extremely expensive, and its processing The manufacturing process is also particularly high, and the manufacturing process of graphene batteries is still not mature enough to be processed in batches. 3. Traditional conductive properties. Carbon/graphite is very cheap, all sold per ton, while graphene is very expensive. The price per gram exceeds 1,000, which is not usually the company can afford, far exceeds the price of gold jewelry, and various types of customers cannot bear it. What's more, technologies such as graphene, not to mention the early stages of the industrial development plan, may take three or four years before they are very likely to appear in current electronic products. 4. Human ingestion of graphene can cause harm to the human body and may be toxic. Unsafe Statement: Some pictures and content of articles published on this site are from the Internet.
