What battery is the best and most durable

　　What are the advantages and disadvantages of graphene batteries compared with lithium batteries?

　　The graphene battery is a single atomic plane film composed of carbon atoms, with a thickness of only 0.34 nanometer. They are the thinnest and strongest nanomaterials in the world, and have good light transmission and folding ability. Graphene is the most conductive material in the world. Adding graphene composite conductive powder to the traditional mobile phone lithium battery can improve the battery's charging and discharge performance and cycle life. Safe and stability, the new graphene polycarbonate capacitance battery, after full charging with a nail gun, makes it short -circuit without response; it will not explode on the fire.

　　The incompleteness of the craft characteristics and the large ratio area of the graphene will bring many process problems to the existing process such as decentralization and homogeneity of lithium -ion batteries. The cycle life refers to the number of battery charging and discharge. standard. Generally speaking, the cycle life of a typical lead -acid battery is only about 500 times. Lithium iron phosphate batteries are 1500-2000 times, and ternary lithium is 1000-1500 times. Graphene is 800-1000 times.

　　If it is a pure graphene battery, the performance in all aspects is better than electric vehicle lithium batteries. However, considering that the current graphene battery products are only partially using graphene technology, their performance should be equivalent to lithium batteries. In terms of price, from the perspective of the battery products launched by Tianneng, Chaowei, and Jinqiu, the price gap between the two batteries is not very large. However, it should be noted that graphene batteries are more stable and safer than lithium -ion batteries in electric vehicles, so choosing graphene batteries has more advantages.

　　Let's take a look at the graphene battery. It is a new energy battery that uses the rapid and large amount of movement between lithium ions on the surface of graphene and the electrode. The biggest advantage of the battery is that it can accommodate a large amount of electricity, which means that it can have the most battery life. In addition, this battery has another main advantage that fast charging time and fast charging. Their weight is half of the traditional lead -acid battery, with a longer life than lithium -ion batteries. However, there is also a disadvantage of graphene battery, because the graphene battery on the market is not pure graphene battery, but only uses some graphene technology, so it has a slight decrease in performance. In addition, the manufacturing process of graphene batteries is also harsh.

　　The best and most durable electric vehicle batteries are lithium titanate batteries, lithium iron phosphate batteries, ternary lithium batteries, graphene batteries, lithium permomylite batteries, black gold batteries, and ordinary lead -acid batteries.

　　1. Lithium titanate battery

　　The durability of lithium titanate batteries is the best in the type of lithium battery. It is charged and discharged 25,000 times in circulation, and the capacity can be maintained at 80%.

　　2. Lithium iron phosphate battery

　　Lithium iron phosphate batteries have a relatively long life, and the lithium iron phosphate battery is high to high temperature resistance, and its safety will be higher. In addition, it also has a high advantage of high circulation. After the battery is looped 1600 times, the battery capacity can reach about 80%.

　　3. Tricss lithium battery

　　It is currently a wide range of batteries. It has become market -dominated in many areas due to the advantages of small size, light weight, and high energy density.

　　4. Graphene battery

　　It is one of the types of batteries that are currently very sought after. There are many big brands such as Yadi, Emma, and Taoling, all of which have launched their own graphene batteries, and graphene batteries retain the advantages of good safety of lead -acid batteries. Because of the addition of graphene elements, the life of the battery is increased.

　　5. Lithium permanganate battery

　　It is a relatively low cost in lithium battery, and it is better to resist low temperature and safety.

　　6. Black gold battery

　　It is a triangle -shaped negative electrode material that compounds graphene, which improves the energy density of the single battery, enhances conductive and corrosion resistance, enhances the combination of conductive body conductive body, and achieves the purpose of extending the battery life.

　　7. Ordinary lead -acid battery

　　As a battery with a very high share of electric vehicles, the advantage of lead -acid batteries is that it is cheap and can be fixed after -sales.
