The bottleneck of the battery makes everyone not want to buy an electric car. With the renewal and iteration of battery technology for electric energy vehicles, the development of lithium batteries (www.tycorun.com) has a tendency to rise from the safflower double stick to the leader of the community. However, it has only risen. Limited by its own performance, cost-effectiveness and other reasons, there is still a long way to go to replace the status of the lead-acid battery, and the lead-acid battery is constantly making self-breakthroughs.
1. Let's start with lead-acid batteries:
The ancestral knowledge of lead-acid batteries
1: The golden bell cover iron cloth shirt (hard!) The lead-acid boss has always been in line with him to make him strong, and the breeze is blowing on the hills. He arbitrarily let him arbitrarily, the bright moon shines on the big river as the principle. Lead-acid batteries are easy to feed, so you can be beaten and beaten. You can continue to use them after a little repair.
2: The price of cabbage (cheap!) The reason why the lead boss has been able to cross the battery community for many years and sit as the boss is all for this reason! Cheap, in addition to cheap or cheap.
3: Recasting (recyclable and reversible repair) lead-acid batteries have their own recyclable skills. After they are worn out, you can go to the electric car shop to exchange the old for a new one. If you make up for the difference, you can change to a new set of batteries to minimize the loss. It is not a small benefit for users.
Now that we have talked about faculty, let's take a look at the shortcomings of lead-acid batteries: large size and weight, limited battery capacity, and short life. Lead-acid batteries generally have a deep charge and discharge within 400 times, have memory, and have a lifespan of about two years. .
The ancestral knowledge of lithium batteries
1: An ancestral light work (light weight, small size) Lithium batteries that have been light and workable since childhood are compared with lead-acid batteries of the same capacity on the market. The volume of lithium batteries is 2/3 of the volume of lead-acid batteries, and the weight is about lead-acid batteries. 1/3 of the weight. Lithium batteries of the same volume have a higher capacity than lead-acid batteries, and the reduction in weight increases the endurance of electric vehicles by about 10%.
2: Longevity and durability (increased lifespan) Lithium batteries are the best way of health preservation. The average lifespan of lithium batteries is about one year, which is about 1.5 times longer than that of lead-acid batteries. The charge and discharge exceeds 500 times. The battery has no memory and has strong shock resistance. .
3: Ancestral Qigong Tuna method (overcharge resistance, good charge and discharge resistance) Lithium batteries have been opened up since childhood, so that they can be continuously charged for 48 hours at normal temperature without battery swelling, leakage and rupture Wait for the accident, the capacity remains above 95%. And under the special charger, it can charge and discharge quickly.
Although lithium batteries have many advantages, their disadvantages are also more obvious.
The production cost of lithium batteries is high. The expensive production equipment and labor costs account for about 40% of the production cost, and the price is about three times that of lead-acid batteries. The price-performance ratio brought by its triple price is not high, and it is quite flashy, and the lithium battery is not recyclable. If it is worn out, it can only be thrown away, or it can be buried somewhere. After thousands of years, later generations will dig it. It's an antique when it comes out.
The most important problem is that lithium batteries have a fire and explosion safety hazard, especially when consumers are deceived by profiteers without their knowledge to buy low-quality lithium batteries. The sealing conditions in electric vehicles are not very good, and they are easy to be exposed to moisture. Poor and other reasons may cause potential safety hazards. However, the technical performance of lithium batteries is also constantly improving, and high-safety materials are being used. The potential safety hazards may be just unnecessary worries for the editor. Maybe it will be the world of lithium batteries in a long time.
Is it better for lithium batteries or lead-acid batteries? At this stage, it can only be determined by demand.
