Are lithium-ion batteries better than lead-acid batteries for electric cars?

Electric vehicles have been developed in China for more than 20 years. Their advantages such as energy saving, environmental protection, convenience and convenience have been favored by people, and the drawbacks are obvious. The lack of endurance makes electric vehicles unable to lift their heads in front of motorcycle big brothers. Many experts and scholars are also painstakingly studying how to change the kidney or kidney to make the electric car regain self-confidence. Among them, lithium battery is a good solution nowadays, and there is a great possibility to reproduce the glory of electric vehicles.

So the question is: lithium batteries and lead-acid battery which is better?

With the updated iteration of electric energy vehicle battery technology, lithium development from a great pool of double-stick saffron rose to the community leader of the trend. However, it is only rising. Due to its own performance, cost performance and other reasons, there is still a long way to go to replace the status of lead-acid battery brother, and the big brother lead-acid battery is also constantly making self-breakthrough.

Today's weather is good, it is up to the old man (who accidentally said leaked) to take the look at the official to understand the battery club inside the red double stick (lithium battery) and the community boss (lead acid battery) homework.

So let's start with a lead-acid battery:

The ancestral school of lead-acid batteries

1: Golden bell iron cloth shirt (hard!) Lead acid boss has always been strong in his strong, he breeze Fushan. He served as his cross, and the moon was based on the principle of the river. The lead-acid battery is easy to support, and you can continue to use it if you drop it and repair it.

2: The price of cabbage (cheap!) Lead boss is able to cross the battery community for many years and sit on the boss's position all for this reason!

3: Re-casting re-casting (recoverable reverse repair) lead-acid battery comes with recyclable skills. After use, you can go to the electric car shop to replace it with a new one, and make up the difference to minimize the loss. It is a small benefit to the user.

Since it is absolutely impossible to learn, then look at the shortcomings of lead-acid batteries: large volume, limited battery capacity, short life, lead-acid batteries are generally deep charge deep discharge within 400 times, have memory, life expectancy is about two years .

Lithium battery ancestral school

1: Ancestral light work (light weight, small size) Lithium battery from a small age, compared with the same capacity lead-acid battery on the market, the lithium battery volume is 2 / 3 of the volume of lead-acid batteries, the weight is about lead-acid batteries 1/3 of the weight. The same volume of lithium battery is higher than the lead-acid battery, and the weight loss increases the electric vehicle's endurance by about 10%.

2: Health and durability (increased life) Lithium battery has a good health, lithium battery life expectancy is about 4 years, 1.5 times higher than lead acid battery life, charge and discharge more than 500 times, battery use no memory, shock resistance Strong.

3: Ancestral Qigong vomiting method (resistance to overcharge, good charge and discharge resistance) Lithium battery from the beginning to open the odd eight pulse, so that under normal temperature, the lithium battery can be continuously charged for 48 hours without battery expansion and leakage When the accident occurred, the capacity remained above 95%. And under the dedicated charger, you can perform fast charge and discharge.

Lithium batteries have many advantages, but their disadvantages are more obvious.

The production cost of the lithium battery is high, the production equipment is expensive, the labor cost accounts for about 40% of the production cost, and the price is about three times that of the lead-acid battery. Its triple price brings the price/performance ratio is not high, it gives people a sense of slickness, and the lithium battery can't be recycled. If it is broken, it can only be thrown away, or find a place to bury it. After thousands of years, later generations dig It’s antiques.

The most important problem is that lithium batteries have the safety hazard of fire and explosion, especially when consumers are unknowingly swindled by profiteers to buy inferior lithium batteries. In electric vehicles, the sealing conditions are not too good, and it is easy to get wet. 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 a little worry. It may be that the world of lithium batteries may not be long before.

Is it a good lithium battery or a lead acid battery? At this stage, it can only be determined by demand. If you have to discuss it, then........ We still discuss whether the scorpion is sweet or salty...

[Electric car era network short comment] Lithium battery to be popular in the electric bicycle industry, will still face the huge resistance of traditional lead-acid battery manufacturers. If the country wants to vigorously promote the development of lithium batteries, it needs to impose more restrictions on the environmental protection standards and weight of lead-acid batteries, eliminate a group of small and medium-sized enterprises, and urge large enterprises to improve technology and transformation. The competition between lithium batteries and lead-acid batteries is inevitable, and many companies have already heard the wind and moved ahead of schedule. On the basis of not giving up the production of lead-acid batteries, we began to lay out lithium batteries. It is predicted that lead-acid batteries and lithium batteries will be equally divided in the future.
