Are rechargeable battery 18650 3.7v still the mainstream technology?

Research shows that although lithium batteries are the future development direction of power batteries, their safety cannot be guaranteed and their costs are relatively high. From the perspective of development trends and speed, the nickel-hydrogen power battery is currently the most industrialized, because nickel-hydrogen battery technology is the most mature and will remain the mainstream of new energy vehicles for a long time in the future. After that, nickel-hydrogen battery technology will share the world with lithium iron phosphate and hydrogen fuel cells. Battery giants Panasonic and Sanyo also believe that lithium-ion power batteries are unlikely to replace nickel-hydrogen power batteries in the near future. The main reason is that nickel-hydrogen power batteries are cheap and safe and have reached large-scale production. Lithium batteries still have topics to be tackled, such as safety, so commercialization will take some time. All hybrid vehicles that have been mass-produced in the world use nickel-hydrogen power battery systems. Toyota has always insisted on the mainstream of rechargeable battery 18650 3.7v in hybrid power. Last year, Toyota built a production line with an annual output of 100,000 units, which is still rechargeable battery 18650 3.7v, which fully proves the vigorous and long-term vitality of rechargeable battery 18650 3.7v in the market.

There was a time when the industry's assertion that "rechargeable battery 18650 3.7v are backward batteries" was very popular. The two most important indicators for considering automotive power batteries are safety and cost. Lithium batteries are the core power batteries of pure electric vehicles, but there has been no substantial breakthrough in the technical difficulties faced by lithium batteries. The first is safety. The hidden dangers of lithium battery fire, combustion and even explosion cannot be completely eliminated. The second is that lithium-ion batteries all need to protect the circuit to prevent the battery from being overcharged and over-discharged. The third is that the production requirements are high and the cost is high. At present, lithium iron phosphate batteries, which are the mainstream technology, still have inherent defects such as large size, heavy weight, slow charging and short battery life.

However, from the perspective of the industrial cycle, nickel-hydrogen power batteries have entered a mature stage and have formed large-scale production, which has price advantages. Moreover, rechargeable battery 18650 3.7v are also the only power batteries that have been actually verified and commercialized and mass-produced in the battery system used in hybrid vehicles. Hybrid vehicles, including Toyota Prius, the world's best-selling car, generally use rechargeable battery 18650 3.7v. It can be seen that in the field of energy-saving and new energy vehicles, rechargeable battery 18650 3.7v are still the mainstream of commercialization. According to my country's new energy vehicle planning, the development in the next few years will be a period of explosion of hybrid vehicles, which will provide development opportunities for rechargeable battery 18650 3.7v with more mature technology and more suitable for hybrid vehicles.
