Introduces a power lithium batteries with normal lithium battery performance difference

Source: 2020 - 04 - 19 20:03 hits: power lithium battery with normal lithium battery performance difference: 1. Lithium iron phosphate, for example, the lithium iron phosphate power battery is mainly composed of the lithium iron phosphate lifecycle 4 peridotite of lithium battery cathode material structure. Lithium iron phosphate power battery is lithium metal or lithium alloy as anode materials, using nonaqueous electrolyte battery solution. And ordinary li-ion battery is made up of manganese acid lithium anode materials, mainly spinel lithium manganese acid material. Hunter in 1981 with three dimensional lithium ion channels were synthesized for the first time of spinel lithium manganese acid lithium lithium anode materials. However, with the development trend of lithium battery cathode material, there may be more high quality anode materials to replace the current material. However, the safety of the battery material application is much more important. The ternary lithium battery or lithium iron phosphate battery 2. Lithium iron phosphate battery and lithium battery voltage difference: lithium iron phosphate battery platform 3 standard voltage. 2 v, 3 full electricity. As 65 v, lithium iron phosphate batteries battery discharge voltage 2. 0v; And ordinary lithium battery voltage of 3. 7 v, after a full charge of 4. 2 v, the battery discharge cut-off voltage of 2. 7v。 In contrast, the lithium battery voltage is higher than the power battery. Lithium iron phosphate can be happened in charge, short time overcharge can recover more than 80%. When lithium ion in 2. 6 v overload, irreversible damage happens. 3. Acid lithium iron batteries puncture can not cause fire or explosion, but normal lithium battery puncture will explode. 4, lithium iron phosphate power battery overcharge to 100% will not fire; E. when the normal lithium battery to would burst. 5, lithium iron phosphate power battery and lithium battery discharge performance difference: lithium iron phosphate power battery can support 30 c discharge rate and unsafe hidden trouble, some lithium iron phosphate battery instantaneous current can reach 600, normal and ordinary lithium battery support for 3 c discharge rate, for the large current discharge of battery feign death occurs. Ternary lithium batteries, lithium iron phosphate power battery and lithium battery weight difference: the same volume of lithium iron phosphate power battery nearly double than normal lithium battery weight. 7, lithium iron phosphate power battery and lithium battery internal resistance is poor: the same volume of lithium iron phosphate power battery is much lower than normal lithium battery internal resistance. 8. Lithium iron phosphate power battery and lithium battery capacity difference: lithium iron phosphate power battery capacity of the same size is lower than normal lithium battery, battery energy density, the anode material of lithium iron phosphate about 60% lower than normal lithium battery. 9, the price of lithium iron phosphate battery and lithium battery: the lithium iron phosphate battery price about 50% higher than that of ordinary lithium batteries. 10. Lithium iron phosphate power battery and lithium battery working temperature: the working temperature of the lithium iron phosphate power battery and lithium iron phosphate power battery, compared to the working temperature of working environment temperature is higher than some of the lithium iron phosphate, and lithium battery working environment temperature is 5 degrees lower. Lead acid battery and lithium iron batteries which is better? 1. Lithium iron batteries light weight, larger than the energy, but safety and cost-effective; The same lead-acid battery weight, volume, specific energy are small, but the security is good, high cost performance, so in this case you are willing to choose to lead acid battery or lithium iron battery? 2. Lithium iron batteries belong to the rechargeable batteries, lead-acid battery belong to alkaline batteries; The cycle of lithium iron batteries is the lithium battery service life of more than 2500 times, circulation service life of the lead-acid battery is lithium battery of about 800 times. Lead-acid battery than to about 40 wh/kg. Lithium iron batteries charging time can be within 4 h is full, and lead-acid battery charging time is generally at about 6 h. 3, lithium iron battery charging and discharging power efficiency is more prominent, the lithium ion battery charging and discharging power conversion efficiency is over 97%, while lead-acid battery charging and discharging electric energy conversion efficiency is about 80%, equivalent to a smaller than lead acid battery is lithium iron batteries, lithium iron phosphate lithium-ion battery volume about two-thirds the size of the lead-acid battery.
