lithium 3400mah 3.7v 18650 battery

　　lithium 3400mah 3.7v 18650 battery technology innovation is one of the foundations of future transportation/energy transformation

　　Recently, Meng Xiangfeng, assistant to the chairman of CATL New Energy Technology Co., Ltd., accepted an exclusive interview with Battery China Network on hot topics such as how to deal with climate change and how lithium 3400mah 3.7v 18650 battery technology can support future urban transportation and energy transformation, and shared CATL’s latest innovative practices. Results.

　　It is urgent to reduce carbon emissions and the energy structure needs to be transformed.

　　Meng Xiangfeng said that the core content of the Paris Climate Agreement is to control global temperature rise within 2°C by the middle of this century, and strive to control it within 1.5°C. However, the current global temperature rise has reached 1.2°C. He believes that the main factor of climate change is caused by energy consumption. While traditional fossil energy brings convenient lifestyles, it also emits a large amount of greenhouse gases. Research by the World Meteorological Organization shows that from 2015 to the present, the earth has been experiencing the hottest five years on record, with temperatures on both land and ocean surfaces reaching record highs. Since the beginning of summer in 2019, extreme temperatures have occurred in many places around the world.

　　At the same time, human demand for energy continues to grow. How to balance the relationship between energy consumption and climate change? Meng Xiangfeng said that solutions to climate change can be found by changing the energy structure. However, the pressure on my country's energy transformation may be greater. In this process, it also needs to face issues such as energy security and environmental protection. With the development of my country's economy, the number of motor vehicles has also achieved rapid growth, and total oil consumption has continued to increase. However, my country's self-produced oil has declined year by year. In 2018, my country's oil dependence on foreign countries exceeded 70%, seriously exceeding the 50% safety warning line, and the political environment of my country's oil import channels is complex, which undoubtedly brings huge challenges to my country's energy security.

　　Traditional car companies accelerate electrification transformation, lithium 3400mah 3.7v 18650 battery technology supports transportation transformation

　　Meng Xiangfeng said that this year's Nobel Prize in Chemistry was awarded to three experts in the field of lithium batteries, which shows that the global industry and academia have regarded lithium 3400mah 3.7v 18650 battery technology as a basic technology for future transportation and energy transformation. Combined with the Boao Consensus of the World New Energy Vehicle Conference, it is expected that the proportion of global vehicle electrification will exceed 50% by 2035, and my country has certain first-mover advantages in this regard.

　　Judging from the trend of global transportation electrification, emission regulations in various countries continue to tighten, making it increasingly difficult for traditional fuel vehicles to meet standards. Taking Europe as an example, many countries have proposed timetables for banning the sale of fuel vehicles and formulated incentive policies such as subsidies for new energy vehicles. Germany's subsidies for new energy vehicles will be increased by 50% and extended for five years. The bicycle subsidy has reached 6,000 euros (approximately RMB 46,469). At the same time, the world's traditional automobile industry giants are also rushing to release their electrification transformation target plans and launch a dedicated electric drive platform for forward research and development, optimizing the chassis layout and vehicle performance. In terms of related supporting facilities, the coverage of private charging piles continues to increase, and the layout of high-power charging piles above 350kW is also accelerating.

　　Meng Xiangfeng pointed out that all means of transportation that can be used frequently are more suitable for electrification, which is also in line with my country's urban planning concept of "promoting electrification starting from the public transportation field". However, some people question that China's electricity source is mostly coal power generation, and new energy vehicles cannot achieve energy conservation and emission reduction in the true sense. In this regard, Meng Xiangfeng said that the proportion of renewable energy use in our country is also gradually increasing. In June 2019, Qinghai Province used clean energy for 15 consecutive days to provide power. All electricity came from green energy generated by water, solar energy and wind power. The province has successfully achieved zero emissions from electricity consumption for 360 consecutive hours, setting a good example.

　　Some organizations predict that the number of new energy vehicles in China will exceed 80 million in 2030. Calculated based on 60kWh per vehicle, the electric energy that electric vehicles can store in 2030 will reach 4.8 billion kWh. According to the 2017 per capita electricity consumption standard, it can satisfy the needs of residents nationwide. Electricity consumption in the past 2 days (according to the National Bureau of Statistics, the daily electricity consumption of national residents in 2017 was approximately 2.45 billion kWh). A large number of electric vehicles can be used as flexible loads on the user side or as distributed power equipment to help regulate the power load of the grid, load peaks and valleys, absorb renewable energy, and provide auxiliary services such as frequency regulation and backup for the grid. Meng Xiangfeng said that Ningde Times has also recently carried out in-depth cooperation with State Grid on V2G. He hopes that this can strengthen the positive interaction between electric vehicles and the power grid and further promote the organic combination of energy, energy storage, and electric vehicles.

　　Breaking through the pain points of industrial development, innovative technology is still the lifeblood

　　Meng Xiangfeng pointed out that power batteries are a capital-intensive and technology-intensive industry, and the intensity of R&D investment and the level of R&D personnel will determine the fate of a company. In the past three years, CATL's R&D investment has reached 5 billion yuan (RMB), the R&D team has exceeded 4,600 people, and the number of patent applications has exceeded 4,800. In terms of product innovation, CATL continues to improve energy density and find the best curve for performance and cost while ensuring battery safety and service life.

　　For consumers, it is inevitable to compare electric vehicles with fuel vehicles. So, can the service life of the power battery meet their driving needs? Meng Xiangfeng believes that battery cells can have the same lifespan as electric vehicles, and the driving range of long-life battery cells can reach 600,000 kilometers. The remaining energy can be used for V2G interaction with the power grid, and can also be used for operations or echelon utilization. As long as the service life is long Long enough, the battery can provide more value. In terms of fast charging technology, the technology currently developed by CATL can charge the battery to 80% in 15 minutes. Based on the complete infrastructure of high-power charging piles, this time is expected to be shortened to 12 minutes in the future.

　　In the long term, as the production and sales of new energy vehicles continue to expand, the demand for metals such as nickel, cobalt, and lithium will continue to increase. Therefore, the impact of upstream resources on the industry is crucial. Meng Xiangfeng pointed out that while CATL continues to improve battery technologies such as ternary and iron-lithium, it also continues to develop new technologies and new system power batteries in the future, and has made a reasonable layout in upstream resources and recycling to maximize Maximize the full life cycle value of power batteries and share the cost of power batteries for new energy vehicles. Finally, he said that the current electrification of global new energy vehicles has just started. For power battery companies, there is still a long way to go in the future. He hopes that companies throughout the industry chain will work together to face more opportunities and challenges.
