The performance analysis of the difference between power lithium battery and ordinary lithium battery

　　1. For example, lithium iron phosphate power batteries are mainly composed of lithium iron phosphate LiFeCoPO4 olivine structured lithium battery cathode materials. Lithium iron phosphate power batteries are a type of battery that uses lithium metal or lithium alloy as the cathode material and uses non-aqueous electrolyte solutions. ; Ordinary lithium batteries are dominated by lithium manganate cathode materials, mainly spinel-type lithium manganate materials, spinel-type lithium manganate LiMn2O4 is Hunter first prepared in 1981 with three-dimensional lithium ion channel cathode material ; But with the development trend of lithium battery cathode materials, there may be more high-quality cathode materials to replace current materials, but the safe application of battery materials is more important no matter what.

　　2. The voltage difference between lithium iron phosphate power battery and lithium battery. What are the main advantages of commonly used lithium batteries? The standard voltage of lithium iron phosphate power battery platform is 3.2V, fully charged is 3.65V, and the discharge cut-off voltage of lithium iron phosphate battery is 2.0V; while the ordinary lithium battery platform voltage is 3.7V, which is 4.2V when fully charged, and the battery discharge is cut off. The voltage is 2.7V. In contrast, the voltage of the lithium battery is higher than that of the power battery; the lithium iron phosphate is resistant to overcharge and overdischarge, and can recover more than 80% after a short time of overdischarge; the lithium ion battery is overdischarged below 2.5V Irreversible damage will occur.

　　3. The power lithium battery will not fire or explode when punctured, but the normal lithium battery will explode when punctured.

　　4. The lithium iron phosphate power battery will not catch fire and explode if it is overcharged to 100%; ordinary lithium battery will gas out and swell when it reaches the specified value.

　　5. Discharge of power lithium battery and ordinary lithium battery: Lithium iron phosphate power battery can support continuous 30C discharge rate without safety hazard. Some lithium iron phosphate batteries can reach 600A instantaneous current, while ordinary lithium batteries normally support 3C. Discharge rate, continuous high current discharge will cause battery false death.

　　6. The weight difference between lithium iron phosphate power battery and lithium battery: The weight of a lithium iron phosphate power battery of the same volume is nearly double that of an ordinary lithium battery.

　　7. Analyze the difference between power battery and lithium battery from the internal resistance: the internal resistance of the lithium iron phosphate power battery of the same volume is much smaller than that of the ordinary lithium battery.

　　8. The difference in capacity between power lithium battery and ordinary lithium battery: the same volume of lithium iron phosphate power battery has lower capacity than ordinary lithium batteries, that is, the battery energy density made of lithium iron phosphate cathode material is 60% lower than that of ordinary lithium batteries about.

　　9. The price difference between lithium iron phosphate power battery and lithium battery: The price of lithium iron phosphate power battery is about 50% more expensive than that of ordinary lithium batteries.

　　10. The working temperature difference between lithium iron phosphate power battery and lithium battery: Compared with the working temperature of lithium battery, the working temperature of lithium iron phosphate power battery is higher, while the working temperature of lithium battery is relatively 5 degrees lower. .
