on september 1, the 2024 world power battery conference officially kicked off. as one of the important activities of the conference, the "new quality productivity" high-end dialogue hosted by the academician ouyang minggao workstation and co-organized by the china all-solid state battery industry-university-research collaborative innovation platform was held at the same time.

the high-end dialogue was hosted by ouyang minggao, an academician of the chinese academy of sciences and chairman of the china all-solid-state battery industry-university-research collaborative innovation platform. leading figures from battery companies participating in the dialogue included liu jincheng, chairman of huizhou yiwei lithium energy co., ltd., yang hongxin, chairman and ceo of honeycomb energy technology co., ltd., meng xiangfeng, vice president of contemporary amperex technology co., ltd., and sun huajun, cto of shenzhen byd lithium battery co., ltd.

academician ouyang minggao and other guests discussed key topics such as "market application field expansion and cost reduction space", "energy storage market and technology trends", "forward-looking technology development trends", and "green manufacturing and going overseas", and expressed authoritative opinions.

1. market application expansion and cost reduction potential

there are obvious opportunities for market application expansion, and cost reduction, sustainable development and technological innovation need to develop in parallel. there is huge market growth space by 2030, and the scale of my country's lithium-ion battery industry will exceed 2 billion kwh. the industry faces a series of opportunities and challenges in market application expansion, cost reduction and sustainable development.

in the field of new energy vehicles, the application of extended-range, large-capacity phev and pure electric 800v high-voltage system power batteries has the fastest growth rate; in the field of energy storage, in addition to its application in power generation, its application in industrial and commercial fields has just begun, and the space prospects are broad.

in terms of cost reduction, we focus on the selection of low-cost material routes, as well as manufacturing cost reduction, process cost reduction and battery form cost reduction. the key is to achieve sustainable cost reduction through technological innovation.

byd battery cto sun huajun also said that what needs to be done is to achieve healthy, orderly and rapid development of the industry without safety issues. on this basis, costs must be reduced. this requires continuous improvement in every aspect. every subtle improvement is an opportunity for us to reduce costs, including extreme manufacturing optimization improvements and reducing costs through technological innovation.

2. energy storage market and technology trends

the healthy development of the energy storage battery industry requires basic skills such as safety, system standardization, and cycle life. "the expansion of lithium-ion battery application scenarios is mainly due to its strong competitiveness in terms of performance and price. as energy storage batteries move towards large capacity, the technical threshold is greatly increased, requiring safety, durability, consistency, manufacturing quality control and other full-chain thresholds. at the same time, smart sensors will play a big role in the field of large-capacity energy storage in the future," said academician ouyang minggao.

liu jincheng, chairman of eve energy, said that the cost of energy storage cells accounts for about 20% of the total cost of the energy storage system. in the future, the cost reduction of energy storage systems will not rely mainly on battery cells, but on the cost reduction of system standardization.

byd battery cto sun huajun believes that we should focus on the underlying logic, combine 7,000 cycles and calendar life, systematically think about the cycle life issue, and continue to pay attention to new manufacturing technologies for large batteries, namely online 100% defect detection technology.

meng xiangfeng, vice president of catl, also said that the industry should master the basic skills in the cycle life of lithium battery energy storage power stations and whether they can play a role in power dispatching. at the same time, lithium-ion battery energy storage should strive to obtain the same support policies as pumped storage capacity electricity prices.

3. forecasting technology development trends

artificial intelligence plays a major role, silicon-carbon anode is the first to be applied, and the research and development of all-solid-state battery technology needs to be done step by step. in terms of forward-looking technology, the introduction of silicon-carbon anode may produce direct technological changes in the short term, which is a broad and sustainable development direction. in the long run, it includes artificial intelligence and all-solid-state batteries. ai technology has been applied in material system test selection, process manufacturing, battery quality management, battery management, etc., which can realize the intelligent work of the whole chain and bring revolutionary changes to the industry.

academician ouyang minggao said that judging from the experience of fuel cell research and development, solid-state batteries still need to be developed step by step. first, the electrolyte problem must be solved, then the negative electrode problem, and then the positive electrode problem. there is no need to rush. breakthroughs in all-solid-state battery materials must rely on artificial intelligence.

yang hongxin, chairman and ceo of honeycomb energy, also said that silicon-carbon has reached a relatively competitive stage and hopes that the industry will pay special attention to intellectual property issues.

meng xiangfeng, vice president of catl, said that the solid-state battery market is booming, but it still needs innovative companies and large chemical giants to enter.

4. green manufacturing and overseas expansion

green manufacturing relies on the rapid development of china's new energy in the long term, and on zero-carbon parks and transfer to areas rich in renewable energy in the short term. the essence of the eu's new battery law is the concept of trade barriers. in terms of battery exports, there are still practices such as choosing to build factories in areas with a large proportion of green electricity and purchasing green electricity to offset carbon emissions in china, as well as domestic power factors, which the eu does not recognize. the eu's new battery law is imperfect and not very operational, and it is urgent to communicate, consult and negotiate with foreign countries. at the same time, when formulating a carbon footprint management system in china, it should study the scientific policies and regulations of foreign countries.

yang hongxin, chairman and ceo of honeycomb energy, also said that in this context, what companies can definitely do is to use recycled materials, which can reduce costs and achieve carbon emissions at the same time.

liu jincheng, chairman of yiwei lithium energy, said that as the amount of battery retirements increases in the future, the recycling of lithium iron phosphate batteries is also an aspect worthy of attention.

academician ouyang minggao said that green manufacturing depends on the rapid development of china's new energy in the long run. in the short term, from the perspective of enterprises, domestic production needs to build zero-carbon parks and move to areas rich in renewable energy. yibin is one of the most promising regions.

as one of the important activities of the world power battery conference, the high-end dialogue continues to play a leading role in "gathering wisdom and meeting the future". with its strong lineup of discussion guests, forward-looking discussion topics, and flexible dialogue format, this high-end dialogue event is known as a "barometer" for insight into industry trends.
