Why has lithium-ion batteries for electric vehicles not been fully popularized in the market?

Why can't lithium-ion battery electric vehicles become popular? The first is the safety of lithium-ion batteries. Through the impact of lithium-ion battery explosions in the past, its people have doubts about the safety of lithium-ion batteries; the second is the price, which is half of the price of lithium-ion battery electric vehicles (the larger the trip is higher) ; The third is practicality. People already have many tools for short-distance travel, such as shared bicycles. Because of these three fundamental reasons, lithium-ion battery electric bicycles must solve these problems and find a development direction if they want to increase their market share. Price and safety are the biggest bottleneck for the failure to open the market for lithium-ion battery electric vehicles. 1. Price One of the most important reasons why lithium-ion batteries has not been able to open up the market in the field of electric vehicles is the price. Due to the high price of raw materials for lithium-ion batteries, The level of manufacturing technology is high, so its cost has always been at a disadvantage compared to lead-acid batteries. Domestic consumers are more sensitive to prices. Market surveys show that the first factor in consumers' purchase of electric vehicle batteries is price. The current market price of lithium-ion batteries is 3 to 4 times that of lead-acid batteries, which is a high price. Consumers often sigh. In addition to the price, the performance of lithium-ion batteries failed to meet consumer expectations is also an important reason. At present, the price of lithium-ion battery electric bicycles is generally several hundred to one thousand yuan higher than that of lead-acid battery electric bicycles, so it is difficult to get consumer recognition on the market. Lithium-ion batteries are light and environmentally friendly, and there will be no environmental pollution after they are discarded. Once the application technology is mature and the market sales increase, the price of lithium-ion battery electric vehicles will come down. 2. Safety issues Safety issues are the sword of Damocles hanging over the head of lithium-ion batteries. The quality of the lithium-ion battery itself needs to be improved. Different from lead-acid batteries, lithium-ion batteries pay much attention to the consistency and stability of the battery in the assembly of batteries. For example, 18650 batteries are used. In series and parallel, the voltage of each battery must be absolutely consistent. Sex. If the cell voltages are inconsistent, the short board effect will appear. Some electric vehicle manufacturers also have a lot of doubts about the safety of lithium-ion batteries and dare not immediately process lithium-ion battery projects. The shadow of lithium-ion battery safety has always been lingering, which severely restricts the further development of lithium-ion batteries. The hidden dangers of fire, combustion and even explosion of lithium-ion batteries cannot be completely eliminated at present. A collision of a vehicle may cause the positive and negative materials of the battery to break through the diaphragm, and the energy quickly recharges to the instantaneous ultra-high current when the battery is braked, etc., which will cause the battery to short-circuit, increase the temperature, and cause combustion or even explosion. The cause of the fire is collision and short circuit leading to the precipitation of lithium, which will cause fire and combustion in contact with air. 3. Maintenance restricts the promotion of lithium-ion battery electric bicycles. The biggest problem is maintenance. If you are in Beijing, repairing is very convenient. The business will replace the defective battery, temporarily replace the old battery for the consumer, and wait for about 10 days before going to the store to replace the original repaired battery. This kind of treatment is not available in every region, which restricts the sales of lithium-ion electric bicycles. Safety performance is the advantage of lithium iron phosphate batteries that are different from other lithium-ion batteries. From the perspective of material cost, with the improvement of domestic lithium iron phosphate material processing factories and the gradual expansion of the processing scale, the price of lithium iron phosphate materials is showing a gradual downward trend, and the price difference with lead-acid batteries is also gradually Zoom out. The price of lithium iron phosphate power supplies with the same capacity may be reduced to 1.5 to 2 times the price of lead-acid power supplies in a short period of time. The high price of lithium-ion batteries is expected to be changed. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
