Are lithium-ion batteries necessarily better than lead-acid batteries?

First equipped with battery. From the consumer level, everyone will think that lithium batteries are more advanced than lead-acid batteries. Many car owners will specially choose lithium battery versions of vehicles to purchase. It sounds advanced and compelling. Some even batteries are more expensive than cars. A sense of nobleness exuded outside. With the gradual deepening of the industrialization of new energy vehicles, countries and key enterprises around the world have stepped up efforts to develop the power battery field of the lithium battery industry. The high specific energy power battery technology based on new materials and structures has become the focus of competition in various countries, and the current vehicles are greatly improved. The safety, life, low-temperature characteristics of power batteries, and cost reduction are the direction of industrial technology development. Driven by policies, China's lithium battery industry has also grown rapidly. Relevant statistics show that the scale of China's lithium battery industry currently ranks first in the world, and the annual lithium battery industry scale maintains a growth rate of 5%. It is estimated that the scale of the lithium battery industry will exceed 600 billion in 2025. ? What about lead-acid batteries, are they really going to be quickly replaced by lithium batteries? In fact, lead-acid batteries have been quite mature after so many years of development in terms of their durability, energy storage, stability, and safety from safety and environmental protection to recycling. Especially it is cheap and can be recycled and reused. The disadvantage is that relatively small and lightweight lead-acid batteries are bulky and low-end compared to lithium batteries. According to the reporter of EQB Electric Vehicle Laboratory, several leading domestic battery companies, from Tianneng to Ningde Times, are currently focusing on the research and development and production of various types of power batteries. After introducing giants such as Panasonic and Tesla in the country, , China’s battery industry will no longer be a brutal start on the original basis, guided by the advantages, but will conduct research and development of various energy batteries based on the vision needed for future global battery applications in various intelligent fields. To put it in a simpler way, after 20 years of development, China's domestic lead-acid battery technology is no longer yesterday's low-end lead-acid battery, but what about lithium batteries? Let me tell you another reality: At present, 95% of the enterprises in my country's lithium battery industry are small and medium-sized enterprises, with small scale and low technical level. They mainly produce low-end lithium battery products. At the same time, from the perspective of global technology, the current stage of global lithium battery technology has not broken through the unsafe bottleneck that is difficult to recycle, flammable and explosive. At this stage, I would like to emphasize it. At the current stage, the environmental protection and relatively low cost of lead-acid batteries, whether in terms of safety, stability or recycling, make lead-acid batteries more widely used than lithium batteries. Therefore, car charging explosions and street fire incidents that people will burst out from time to time in various places will cause people to deeply worry about the future era of electric vehicles. What directly leads to these insecurity concerns is the current immature lithium battery technology and market interest trends. Under the circumstance, the uneven lithium battery products that quickly flooded the market. Therefore, don’t simply define it as: Lithium batteries must be better than lead-acid batteries! From the perspective of sustainable development, the unrecyclable and explosiveness of lithium batteries are currently unresolved obstacles. At this stage, there is still no way to completely replace lead-acid batteries. Regardless of economy or sustainability, lead-acid batteries are currently superior to lithium batteries. We do not want to deny the advantages brought by lithium batteries, but without breaking through the technical bottleneck at the current stage, we should understand this more objectively and clearly. Or, for consumers, whether lithium batteries or lead-acid batteries, it is important to choose batteries from brand manufacturers.
