It will take three to five years for lithium batteries to replace lead-acid batteries

Abstract: from the perspective of price and policy, lithium electrification of low-speed electric vehicles and the replacement of lead-acid batteries are the trend in the future, but there will be a long process

under the catalysis of policies, this year, the low-speed electric vehicle industry has witnessed a vigorous trend of lithium batteries. The momentum is as strong as reading. In the main production and marketing areas of low-speed electric vehicles, it is announced that with the increase of the number of uses, lithium batteries will be listed. From dealers to consumers, they are all interested in the concept of "ignorance". And according to Xiaoman, there are not a few lithium battery products that will be launched in the second half of this year. Lithium battery enterprises are also in frequent contact with low-speed electric vehicle enterprises, planning to develop a set of reasonable supporting schemes for this special category of low-speed electric vehicles. All this shows that before the policy was introduced, low-speed electric vehicles have quietly upgraded themselves

but can lithium electrification of low-speed electric vehicles completely replace the lead-acid battery market? This should be mentioned from three aspects:

01 price

the users of low-speed electric vehicles are middle-aged and elderly people at the township level in third and fourth tier cities. Their consumption ability is limited, and they want to find a comfortable way to travel. In the preheating stage of the hot forming process of thick wall products, the surface may have melted, foamed and even decomposed, which breeds the development of low-speed electric vehicles. It is not denied that low-speed trams are an industry in a gray area, and even some low-speed electric vehicle drivers are potential risk bombs on the road, but these can not stop people from loving low-speed electric vehicles, which are cheap means of transportation. With the convenience of being cheap and rain proof, low-speed electric vehicles have broad prospects for development in China

in the whole price share of low-speed electric vehicles, batteries account for the majority. The domestic market is that the price of lead-acid batteries is far lower than the price of lithium batteries. Low speed electric vehicles are equipped with lead-acid batteries, without state subsidies, and completely rely on market economy. The price will double on the existing basis. Therefore, a battery will make the travel cost soar, and those consumers of low-speed electric vehicles may find it difficult to pay again. Moreover, consumers who buy low-speed electric vehicles are too expensive, and those who buy fuel vehicles are too low-grade. The subsequent results of low-speed electric vehicles are likely to be ignored

02 use experience

lithium batteries are too "delicate" to withstand the toss like lead-acid batteries. During the use of lithium trams, they can't stand the impact of falling and throwing. Once the lithium battery is punctured or broken by violent impact, the lithium battery may burn and explode; Lithium batteries have high requirements for chargers. You can't charge with coin operated chargers on the side of the road like lead-acid batteries. Once the current is too large, it may cause combustion or even explosion if it breaks through the protective plate in the lithium battery

the long repair time has seriously restricted the use of consumers. In case of lithium battery failure, the repair time is about a week or even longer, which makes consumers impatient and lose confidence in use. The reason is that the dealer cannot repair or replace the battery with problems inside the lithium battery. It must be transported to the manufacturing enterprise by express delivery, and the battery can be repaired by professional equipment. This is one of the keys that restrict the large-scale replacement of lead-acid batteries by lithium batteries

03 policy

under the background of the state's emphasis on the use of lithium batteries in low-speed electric vehicles, the government has taken action on the lithium battery industry, and the price of lithium batteries must decline, which is likely to fall to the same price as lead-acid batteries in the future. Although the lithium battery technology is mature, domestic manufacturers' grasp of the graphite used in the pencil core is equivalent to countless layers of graphene stacked in one. The technology of lithium battery anode and cathode materials has not reached the stage of low-cost research and development of lithium batteries. In the next three to five years, the price of lithium batteries may be difficult to compete with lead-acid batteries and win consumer recognition
