In a short period of time, lithium batteries cannot completely replace lead-acid batteries

Lithium batteries are difficult to replace lead-acid batteries in a short period of time. Low-speed electric vehicles on the market are still dominated by lead-acid batteries. Even if the new national standard takes effect, the new policy cannot replace lead-acid batteries with lithium batteries in a short period of time. Acid battery. Why is this? Let's elaborate on the lithium battery manufacturer below. Lithium batteries replace lead-acid batteries in the context of the environment. With the strong support of national policies, electric vehicles will be led to lightweight lithium batteries, and the replacement of lead-acid batteries by lithium batteries is a long-term process. In 2020, many companies including China Tower stated that they will no longer use lead-acid batteries. The iterative upgrade of lithium battery technology driven by new energy vehicles has qualitatively improved in terms of safety performance and energy density. The cost of lithium batteries is getting closer and closer to lead-acid batteries, and the market has delivered a lithium battery to replace lead. The signal of an acid battery, but it is not so simple for a lithium battery to replace a lead-acid battery. 1. The cost advantage of lithium batteries is not outstanding. From the current situation, the performance of lithium batteries is not satisfactory. The price of lithium batteries is about 1.5-3 times that of lead-acid batteries, but the maintenance rate is still higher than that of lead-acid batteries. high. In addition, the manufacturing cost of lead-acid batteries is undoubtedly the lowest, whether it is electrode materials, electrolyte, or assembly environment requirements, are far lower than lithium-ion batteries. 2. The popularization of technical capabilities and the difficulty of repairing. Long cycles. Lithium battery failures require professional equipment to be repaired. Generally, stores do not have lithium battery repair technology. If you need to return to the factory for repair, the cycle may be very long. 3. The safety performance of lead-acid batteries is undoubtedly better. Even if the current lithium batteries have added more protection, the safety of lithium iron phosphate batteries is also very high, but compared with lead-acid batteries, it is still very safe. Big gap. 4. Both lithium batteries and lead-acid batteries pollute the environment. If the correct recycling method is not used, the waste of lithium batteries will still pollute the environment, and the lead-acid battery industry has undergone a century of technical precipitation, as long as there is good The environmental protection damage can actually be avoided if lead-acid batteries are recycled and reused. And in some specific industries, lead-acid batteries are irreplaceable, so in a short period of time, lithium batteries are unlikely to replace lead-acid batteries. The new national standard for electric vehicles stipulates that the weight limit of the entire vehicle, including the battery, should not exceed 55 kilograms. At the same time, the new national battery standard also makes strict regulations on battery technical conditions, product quality, and product specifications: 1. Require batteries to be lightweight design to increase energy density instead of weight; 2. Mandatory setting of battery cycle charging life. Less than 350 times; 3. Comprehensively raise the technical threshold of lead-acid battery access. With the increasingly fierce competition in the electric bicycle industry, intelligent, lightweight, fast charging, long battery life, long life, and high cost performance have become essential for electric bicycles. From the lightness of electric bicycles, lithium batteries are indeed a trend. . But in any case, the change from lead to lithium in electric vehicles is a good thing for the consumer experience and the boost to the industry. I hope that the pace of lithium battery for electric vehicles will go further, and lithium batteries will gradually become the mainstream in the future. .
