Analysis of the gap between my country's power lithium-ion battery and international batteries

Analysis of the gap between my country's power lithium batteries and international batteries, compared with the world, the battery power gap is too large. At present, nearly 90% of battery companies in my country still assemble and produce by hand. Compared with foreign countries, the technology is too backward. It is understood that no more than 5 people currently master the core skills of automotive battery development in my country. No matter what kind of battery, from the current point of view, my country's technology is still relatively backward. Lead-acid batteries are more complex than lithium-ion batteries and easier to control in terms of waste recycling. Therefore, the question of who is more environmentally friendly should not be comparison, but the perfection of technology. The ternary lithium-ion battery produced by Panasonic has very significant advantages in terms of charging and discharging functions and battery life capabilities, but it has poor stability compared with lithium iron phosphate batteries. Tesla uses Panasonic's ternary lithium-ion batteries, because Panasonic holds shares in Tesla, which means they are not a supplier. It is unclear which battery is more suitable for electric vehicles. The key is whether the company is looking for battery life or safety. At present, the output of vehicle batteries that meet the specifications in my country is very small, and most of the batteries produced by the company do not meet the specifications. If they do not meet the specifications, they will not be recognized by the manufacturer, so they cannot be counted in the capacity of the batteries on board. Because the barriers to entry for lithium-ion battery companies are very low, and many companies adopt government-supported electric vehicles, everyone is staring at this Tang Seng meat, but car batteries have the most stringent skills in the battery category, not anyone who wants to do it. of. Analysis of the gap between my country's power lithium battery and the world Wang Zidong, director of the National 863 Electric Vehicle Major Project Power Lithium Battery Test Center, believes that in the initial development of this emerging industry, we should be rational and not blindly follow the trend. For an electric car worth $100,000, technology is a must, and Tesla is nothing new. I think some media are biased against Tesla's hype. In the world, there are related test specifications for the safety functions of car batteries, but Tesla does not. Many people now say that Tesla has no safety accidents, which does not mean that there are no safety risks. The media should not draw conclusions prematurely, but should play cards according to common sense. In the field of new energy, the government can only grasp major policies and policies, not intervene in everything, and not engage in ubiquitousness. It must adhere to four items, namely, restrictions, incentives, regulations, and sanctions to truly make my country's electric vehicle industry bigger and stronger .
