From these products, we see the same points:


1. Safety. A series of safety incidents involving electric vehicle lithium batteries have deterred many new energy car owners from purchasing electric vehicles. How to ensure the safety of lithium batteries has become the primary consideration for lithium battery companies. In the products released by each company, they also mentioned what methods they have adopted to make batteries safer;


2. Energy replenishment. Compared with fuel vehicles, electric vehicles have always been at a disadvantage in terms of energy replenishment. Therefore, improving energy replenishment efficiency is a difficulty that all lithium battery companies must overcome. The cruising range that can be achieved within a certain charging time is another measure of the battery's fast charging capability. The U.S. Department of Energy (DOE) defines 6C charging as charging to 80% of the battery within 10 minutes, adding 322 kilometers of vehicle range. At present, all major lithium battery companies are constantly moving towards this indicator through technological innovation. Another way is to swap batteries. At present, CATL, BAIC, Aodong New Energy, NIO, Geely, FAW, SAIC, GAC and other companies have invested considerable manpower and material resources in developing battery charging and swapping station business. However, due to the high investment cost and narrow compatibility of charging and swapping stations, the speed of popularization is greatly limited. However, both at the government level and within the industry, there is an intention to formulate unified standards and lower the threshold for popularizing charging and swapping stations. Perhaps in the future, charging and swapping stations can be as common as gas stations today;


3. Battery mileage. Judging from the current data released by major lithium battery companies, electric vehicles have caught up with or even surpassed fuel vehicles in terms of cruising range, and there is still a lot of room for improvement in the future;


4. Reduce costs. Regardless of whether it is Yiwei Lithium 4695 large cylindrical battery, Guoxuan Hi-tech semi-solid battery, Zhongxin Aviation One-Stop's high manganese iron lithium battery, or Panasonic cylindrical battery, when they were released, they all mentioned the cost improvements of the products. optimization.


From these aspects, as various lithium battery companies continue to make breakthroughs in product technology, based on the needs of different application scenarios, multiple technical routes develop together and learn from each other and integrate, constantly promoting the optimization of battery performance and cost. The performance of new energy vehicles in all aspects continues to catch up or even surpass that of fuel vehicles, and is accepted by more and more intended car owners. The trend of new energy vehicles replacing fuel vehicles is becoming increasingly obvious. And judging from the current development trends of various companies, in the future, leading battery companies will build diversified technical routes to adapt to the application needs of different car companies and scenarios.


Finally, China has the world's largest new energy vehicle market, which is a huge advantage for Chinese lithium battery companies. This has also helped Chinese lithium battery companies occupy six of the top ten global power batteries, with a market share of more than 65%. In addition, relevant Chinese companies have controlled more than half of the world's lithium resources, a large part of which is in the South American Lithium Triangle, that is, Argentina, Chile, and Bolivia. These three countries have all joined the Belt and Road Initiative, and Chinese companies have invested here. There are huge political advantages in lithium mining and lithium mining. It is foreseeable that China will not be in a situation where there is no "lithium" available in the short term.


It can be said that in the field of lithium batteries, China has taken the leading advantage in all aspects of technology, market, and raw materials. Whether now or in the future, China will definitely have a huge say in the field of lithium batteries. But in the field of lithium batteries, the leader has changed hands several times, first to Japan, then to South Korea, and now to China. However, both Japan and South Korea are unwilling to give in and are always trying to catch up. In addition, Europe and the United States are also watching eagerly. China is far from the time to sit back and relax.
