[Approaching "New Three Samples"] New Energy of Power Battery Technology
my country's cumulative sales of power batteries reached 616.3 gigawatt hours, an increase of 32.4 percent year-on-year; cumulative loading 387.7 gigawatt hours, an increase of 31.6 percent year-on-year; cumulative exports reached 127.4 gigawatt hours, an increase of 87.1 percent year-on-year. Among the top 10 power battery companies in the world, Chinese companies occupy 6 seats... On January 11, 2023, the report card of the power battery industry was released.
Thanks to continuous technological innovation, industrial structure innovation and business model innovation, the market scale of China's power battery industry has been leading the world for seven consecutive years, and its leading position in the industry has been continuously consolidated.
Direct strike, fill energy "pain point", continuous force material system innovation and structural innovation.
The volume utilization rate of the battery is 83.7 percent, ranking first in the world; charging for 15 minutes, the battery life is increased by more than 500 kilometers, is currently the world's fastest mass-produced lithium iron phosphate battery... The polar krypton 007 pure electric coupe launched at the end of 2023 is the first to carry a polar krypton self-developed BRICS battery with 75 degrees of electricity and a maximum range of 688 kilometers. This battery not only improves the mass energy density of the lithium iron phosphate battery pack by more than 10% compared with the traditional ternary lithium battery pack, but also truly realizes "charging thousands of miles in a moment".
6:30 from Shanghai, 20:33 arrived in Xiamen, the whole journey without power 1044 kilometers... December 2023, Weilai car founder, chairman and CEO Li Bin test Weilai "150 degree battery pack", took about 14 hours to successfully complete the 1000km endurance challenge.
After the energy density of mass-produced power battery cells exceeded 300 watt-hours per kilogram and the average driving range of pure electric passenger cars exceeded 460 kilometers, China's power battery enterprises continued to make structural innovation and electrochemical system innovation in 2023, and the technical level reached a new level.
"In order to be able to place more cells in the battery pack, the engineering team has completely reformed the battery pack structure." Xie Shibin, vice president of polar krypton intelligent technology, told reporters that compared with the traditional design, the total length of the BRICS battery sampling line has been shortened by 157 meters and the number of core components has been reduced by 35%.
Pole krypton makes the power battery life stronger through the extreme use of the battery compartment space. Zero Run chose battery chassis integration (CTC) technology. On January 10, 2024, Zero Run announced that the new C10 model launched in March will be equipped with Zero Run CTC2.0 technology. "The volume utilization rate can reach 79%, the number of parts is reduced by 28%, the cost of structural parts is reduced by 27%, the torsional rigidity of the whole vehicle is increased by 48%, the light weight level of the system is increased by 15%, and no fire, explosion and heat diffusion in 720 seconds can be realized." Song Yining, vice president of the zero-run battery product line, said that from large modules to no modules, from battery plug-ins to integrated integration, domestic enterprises adhere to differentiated innovation and stand at the forefront of global battery technology.
Compared to structural innovation, the disruptive innovation of the power battery electrochemical system, represented by solid-state batteries, is expected to completely solve the battery life, energy and safety problems. In July 2023, Toyota announced a major breakthrough in solid-state battery research and development, and will achieve mass production in 2027. Since then, SAIC, GAC, Chang 'an and other car companies have said that they will achieve mass production of solid-state batteries by 2027.
Entering Qingtao (Kunshan) Energy Development Co., Ltd., R & D personnel are working hard with engineers from SAIC Innovation Research and Development Institute to promote the mass production of the first generation of semi-solid batteries. "The first-generation semi-solid-state battery jointly developed by us and SAIC will take the lead in mass production in the third quarter of this year and will be installed on brand-new models of the Zhiji brand." Li Zheng, general manager of Qingtao Energy, said that the new car equipped with this generation of semi-solid battery technology can have a maximum range of more than 1000 kilometers and an increase of 400 kilometers after 10 minutes of charging. Next, the second-generation semi-solid-state battery, under the premise of better performance, will reduce the cost of existing battery products by 10%-30%, and quickly complete the mass production of "100000-class scale.
"Right now, we are steadily advancing the mass production of sodium batteries, ferromanganese aluminum phosphate batteries, and condensed matter batteries. At the same time, we are actively storing future-oriented next-generation battery technologies in order to lead the new energy industry to reduce costs and increase efficiency." Ni Jun, chief manufacturing officer of Ningde Times and co-president of engineering manufacturing and R & D system, told reporters that in the face of new opportunities and challenges in the industry, China's power battery enterprises have not and will not stop the pace of innovation.
Break the "difficulties" of cost and efficiency, and promote the innovation of industrial structure and business model.
The ground is spotless, the equipment is clean and tidy, and you have to wear white dust-proof clothing when you enter... Entering the battery cell workshop of Zhejiang Quzhou Polar Electric New Energy Technology Co., Ltd. (hereinafter referred to as "Quzhou Polar Electric Factory"), it seems to be in a huge hospital operating room. The air cleaning system here can ensure that there are less than 293 dust particles above 5 microns per cubic meter of air. The nearly "zero moisture" control system makes the humidity in the workshop only half of the lowest humidity in a year in the Sahara desert, ensuring that the moisture content ratio of a single cell is less than 2/10000.
The world's largest integrated manufacturing base for three power and energy storage systems with a construction area of 1.46 million square meters was wholly owned by Geely Holdings. It took only 14 months from construction to production. In 2023, Geely is not the only vehicle company involved in cell manufacturing and has achieved phased results.
On November 24, 2023, the first standard battery produced by Times Changan Power Battery Co., Ltd. rolled off the production line in Sanjiang New Area, Yibin, Sichuan. According to the plan, Chang 'an Automobile will introduce 8 battery cells in 2030, including liquid, semi-solid and solid, to form a battery capacity of not less than 150 gigawatt hours. The first CTC technology with a group efficiency of 86% will be mass produced this year.
More than half a month later, GAC's Inpai battery intelligent ecological factory was completed. The factory has invested 10.9 billion yuan and plans to build 36 gigawatt-hours of power battery and energy storage battery capacity, which can meet the loading demand of 600000 new energy vehicles. It is reported that GAC independently developed a solid-state battery with an energy density of 400 watt-hours per kilogram, which is planned to be mass-produced and loaded in 2026.
"The competition for new energy vehicles has entered the second half, with the focus on energy supply in addition to intelligence. Vehicle companies need to be able to provide more convenient, cheaper and greener energy to meet consumers' demand for green travel." Feng Xingya, general manager of GAC Group, said that GAC's energy ecological sector aims to enhance its soft competitiveness beyond hard products.
An Conghui, president of Geely Holding Group and CEO of Extreme Krypton Intelligent Technology, said that the power battery is one of the core and most expensive parts of new energy vehicles, which is related to cost and direct user experience such as safety, battery life and charging efficiency. Car enterprises full stack self-research battery, is to enhance the technical strength, dig deep brand "moat", grasp the competitive initiative of the key link.
"No matter whether we use purchased batteries or self-developed batteries, for vehicle enterprises, we must achieve the perfect combination of electricity and vehicles." An Conghui said that the difference in user experience between a platform-based, universal, and standardized purchased battery cell and a battery cell tailored for a car may be 98 points and 100 points. "The difference between these two points is extremely krypton. Differentiated competitive advantage."
"Vehicle companies have laid out the entire power battery industry chain and made substantial progress in self-research and self-production of battery cells, which has changed the existing industrial division of labor and industrial structure of power batteries, and promoted technological progress and product iteration." Wang Yao, assistant secretary-general of the China Association of Automobile Manufacturers and deputy secretary-general of the Power Battery Industry Innovation Alliance, said that in 2023, my country's power battery business model innovation has also made breakthrough progress. The landmark event is that Weilai Automobile has successively cooperated with the two major OEMs of Changan and Geely. The factory cooperates in the power exchange business.
According to reports, the power exchange mode and the resulting "vehicle-electricity separation" sales mode of pure electric vehicles are one of the major achievements of China's new energy vehicle business model innovation. The Ministry of industry and information technology has repeatedly made it clear that it supports the development of new energy vehicle power exchange mode and starts the application pilot. However, due to the inconsistent specifications of the battery packs of various car companies and battery companies, the power exchange stations cannot be compatible, making this model unable to give full play to its advantages.
"The sharing of power exchange mode helps to break through the key obstacles of power battery life cycle management." Wang Yao believes that under the traditional mode, the ownership and disposal of car bodies and batteries are in the hands of consumers, which brings certain difficulties to standardized and large-scale recycling. "The separation mode of car and electricity is expected to give birth to professional battery banks and battery management companies. The batteries they rent, sell and trust are large-scale, easy to standardize and have complete data, which is conducive to improving the efficiency of echelon utilization and dismantling and recycling after battery scrap."
Around the safety, carbon reduction "focus", the full implementation of intelligent, green transformation
18 key processes, 100 percent automatic operation of the whole process production line; more than 200 intelligent handling robots, to achieve automatic on-line, line side material circulation distribution and other multi-scene automatic transportation; industry's first pole piece "double pump coupling technology" and "beta ray and laser double light control monitoring and feedback system", online real-time error correction ...... into the Quzhou polar electricity factory, highly automated, intelligent to bring high efficiency and high quality, people's eyes.
"As the first three-power 'Factory of the Future' pilot enterprise in Zhejiang Province, Quzhou Polar Power Factory uses the '5G Industrial Internet' as the carrier to deeply integrate advanced technologies such as big data, artificial intelligence and digital twins. Today, the battery cell factory has achieved an industry-leading level of one cell per line offline every 2.5 seconds, and the battery factory has achieved an industry-high efficiency of 46 cells per production line per minute." Xie Shibin said.
Comprehensively promote intelligent manufacturing, so that China's power battery enterprises in the cost, efficiency, product yield and other core indicators continue to lead the world, for the product "going out" to lay a solid foundation. At the same time, China's power battery enterprises actively respond to the EU Battery Act, through the creation of zero-carbon plants, the establishment of an internationally recognized carbon footprint accounting system to implement green transformation.
Open the electronic billboard of the plant facility management system, and the real-time energy consumption of the five major factories of Sichuan Times New Energy Technology Co., Ltd. under Ningde Times is clear at a glance.
Xu Bin, head of Sichuan Times Factory, told reporters that the system inspection and analysis found that 63% of the factory's energy consumption was generated by equipment and 37% of the energy consumption came from production gas and refrigeration equipment. The enterprise then shifted the focus of energy saving and consumption reduction from air refrigeration to the equipment end. In March 2023, Sichuan Times developed a new digital management system for energy consumption in all production links, allowing the equipment to be turned on on demand and enter standby mode like a smart phone "off screen.
At present, more than 80% of Sichuan's energy comes from hydropower, which can reduce carbon emissions by 400000 tons per year. The green energy solution of "all hydropower + zero carbon natural gas" will help the enterprise become the world's first battery zero carbon plant in March 2022. "Next, we will make every effort to promote energy conservation and carbon reduction to extend to upstream primary and secondary suppliers." Zhu Yunfeng, general manager of Sichuan Times New Energy Technology Co., Ltd., said.
