Why do high-end electric sweepers have to choose lithium iron phosphate batteries?

Why high-end electric sweeper must choose lithium iron phosphate battery. Lithium electric sweeper is a brand-new environmental protection equipment. The equipment is stable and full of first. Many manufacturers choose ternary lithium batteries with higher energy density. I personally support more Safe lithium iron phosphate battery. The ternary lithium battery is unreliable in terms of safety. In an accident, external impact will damage the battery gap and cause a short circuit. The heat generated by the short circuit will cause the battery to lose control of the heat and quickly increase the temperature to above 300°C. Ternary lithium battery has poor thermal stability. If it stays below 300°C, oxygen molecules will decompose. When the battery encounters flammable electrolyte and carbon data, it will come into contact with the battery. In contrast, another widely used lithium iron phosphate battery can last 700-800 degrees Celsius and is safer without decomposing oxygen molecules. For safety reasons, ternary lithium battery passenger vehicles were once unable to enter the list of new energy vehicles recommended by the Ministry of Industry and Information Technology. Lithium batteries must choose regular manufacturers, because in actual processing, there is no confidence in lithium iron phosphate batteries that are considered safe and reliable. During the preparation process, iron oxide may be reduced to elemental iron in a high temperature environment. Elemental iron can cause a micro short circuit of the battery, which is a contraindicated material for the battery. In addition, the charging and discharging curves of lithium iron phosphate batteries are quite different in practice, with poor consistency and low energy density, which directly affect the sensitive battery life of electric vehicles. In order to safely choose lithium iron phosphate batteries, lithium iron phosphate batteries should use professional battery processing system BMS, a battery processing system suitable for electric sweepers. Electric sweepers currently use lead-acid batteries in most companies, while lithium battery sweepers are slowly appearing in our country. There are also several professional lithium battery sanitation small electric sweeping machine manufacturers. The following are the differences between lead-acid batteries and lithium batteries: 1. In terms of voltage, the single grid voltage of lead-acid batteries is 2V, and the average voltage of lithium batteries is 3.7v; 2. In terms of capacity, due to different data, the activity of lead-acid batteries is not as good as that of lithium batteries. High, so the capacity of the equal capacity lithium battery is greater than that of the lead-acid battery; the mass and volume ratio of the lithium battery is about 40% higher than that of the lead-acid battery. 3. In terms of safety, the data safety of lithium batteries (lithium manganate, lithium iron phosphate) has different differences. The current lead-acid battery technology is quite mature, and the safety is higher than that of lithium batteries. 4. In terms of price, the price of a lithium battery with the same capacity is two to three times that of a lead-acid battery.
