How to choose lead-acid batteries and lithium batteries

Most electric vehicles currently on the market use lead-acid batteries. Its key features are. Reliable stability and mature technology. And can be recycled. Simply put, it is more economical. The depreciation price of old batteries is reclaimed to a large extent. The advantages of the price of new batteries are more obvious. The disadvantage is that traditional lead-acid batteries have low mass and volume energy density. The energy density is only about 1/3 of that of lithium batteries, and about 1/2 of that of nickel-hydrogen batteries, and they are relatively large, which is not suitable for light and small size Occasion use. The cycle life of traditional lead-acid batteries is short, and the theoretical cycle number is about 1/3 of lithium batteries. There is still much room for improvement in the cycle life of lead-acid batteries, especially lead-acid batteries with new materials, new structures and new technologies, such as bipolar lead-acid batteries and lead-carbon batteries. Lead is an important raw material for lead-acid batteries. Lead accounts for more than 60% of the battery quality. Lead-acid batteries worldwide account for more than 80% of the total lead consumption. Lead is a heavy metal, and the lead-acid battery manufacturing industry chain (including primary lead smelting, battery manufacturing, battery recycling, and secondary lead smelting) has a high risk of lead pollution. Poor management can cause environmental pollution and harm to human health. Then let's take a look at lithium batteries. The most obvious feature is its smaller size. And the weight is lighter, and the disassembly is very convenient. It is known that the weight of a lithium battery is only 1/2 or even lower than that of a lead-acid battery for the same voltage. Of course, lithium batteries have a longer life. In fact, the use effect is twice that of lead-acid batteries. of course. No matter what kind of product it is, it is impossible to achieve perfection. Lithium battery prices are generally higher. It is twice that of lead-acid batteries. And the old battery does not have any distinct advantages. Scrap straight away. There is no value. This has no economic advantage to a large extent. Your battery also has a fatal flaw. It is the poor safety performance, and there are great safety risks. Both have their own advantages and disadvantages. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
