The key factors for the unsatisfactory development of China's energy vehicles include range, charging speed, and safety features. These three factors are caused by the inadequate technology of power lithium batteries, and therefore can also be regarded as the three technical bottlenecks of power lithium battery packs. Analyzing the three technical bottlenecks of power lithium battery packs 1. Short range: As technology continues to mature, the range of electric vehicles using lithium batteries as power source has increased from less than 100 kilometers at the beginning to 300 kilometers as the mainstream at that time. Around 200,000 kilometers, the cruising range of a single model exceeded 400 kilometers. However, there is still a certain distance compared with the mainstream journey of 500 kilometers for fuel vehicles at that time. This problem can be solved by using multiple strings of single cells, but the negative problem is that it is too large and makes it inconvenient for the car to travel. 2. Slow charging speed: Compared with the short journey, the slow charging of lithium battery packs is a greater restriction on the development of electric vehicles. At normal speed, it takes 4 to 8 hours for the lithium battery of an electric vehicle to be fully charged. There are also quick-rechargeable lithium batteries that can be fully charged within 1 to 2 hours, but their negative effects are huge. The lifespan will be reduced to 1/3 of the original, and the battery performance will be significantly reduced. Fuel vehicles do not have these problems. The refueling time does not exceed 5 minutes, and safety and stability can be guaranteed. 3. Safety functions need to be improved: Since the birth of lithium battery packs, safety issues have always puzzled consumers. From mobile phones and laptops to now electric vehicles, safety accidents continue to occur. In addition to no reports of fires in electric vehicles from Nissan and Tesla, electric vehicles from China's Zotye and BYD, and the United States's General Motors and Fisker have all spontaneously ignited or caught fire. The existence of the above three problems has caused the research and development costs of lithium batteries to overcome these three shortcomings to increase. High-priced products also restrict the development of power batteries and power battery electric vehicles. This article’s technical bottlenecks in power lithium battery packs are compiled and provided by lithium battery manufacturers.
