What are the differences in performance between power lithium-ion batteries and ordinary lithium-ion batteries

1. For example, lithium iron phosphate lithium ion power battery is mainly composed of lithium iron phosphate lithium ion LiFeCoPO4 olivine structure lithium ion battery cathode material, lithium iron phosphate lithium ion power lithium battery is a type of lithium ion metal or lithium ion alloy as the cathode material 、Batteries using non-aqueous electrolyte solutions; while ordinary lithium-ion batteries are mainly made of lithium manganate ion cathode materials, mainly spinel-type lithium manganate ion materials, spinel-type lithium manganate ion LiMn2O4 was developed by Hunter in 1981 The first produced cathode material with three-dimensional lithium channels; but with the development trend of lithium-ion 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. What are the important advantages of commonly used lithium-ion batteries for the voltage difference between lithium iron phosphate power lithium batteries and lithium-ion batteries? The standard voltage of lithium iron phosphate power lithium 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 ion battery platform voltage is 3.7V, and it is 4.2V after fully charged. , The battery cell discharge cut-off voltage is 2.7V, compared to the lithium-ion battery voltage is higher than that of the power lithium battery; lithium iron phosphate is resistant to overcharge and overdischarge, and can recover more than 80% when it reaches 0 for a short time; Irreversible damage will occur when over-discharged to 2.6V. 3. Lithium-ion battery powered by iron acid iron will not fire or explode when punctured, but normal lithium-ion battery will explode when punctured. 4. Lithium iron phosphate lithium ion power lithium battery will not catch fire or explode if it is overcharged to 100%; ordinary lithium ion battery will gas out and swell when it reaches the specified value. 5. Different discharge aspects of power lithium ion battery and ordinary lithium ion battery: lithium iron phosphate lithium ion power lithium battery can support continuous 30C discharge rate without safety hazards. Some lithium iron phosphate batteries can reach 600A instantaneous current, while ordinary Lithium-ion batteries normally support 3C discharge rate, and continuous high-current discharge will cause battery false death. 6. The weight difference between lithium iron phosphate lithium ion power battery and lithium ion battery: The weight of the same volume of lithium iron phosphate lithium ion power battery is nearly double the weight of ordinary lithium ion batteries. After testing the difference between power lithium-ion battery and ordinary lithium-ion battery, I awakened outright. 7. Analyze the difference between power lithium battery and lithium-ion battery from the internal resistance: the same volume of lithium iron phosphate lithium-ion power lithium battery has much lower internal resistance than ordinary lithium-ion battery . 8. The difference in capacity between power lithium-ion batteries and ordinary lithium-ion batteries: the same volume of lithium iron phosphate lithium-ion power lithium batteries has lower capacity than ordinary lithium-ion batteries, that is, the battery energy density made of lithium iron phosphate cathode materials is higher than that of ordinary lithium The energy density of ion batteries is about 60% lower. 9. The price difference between lithium iron phosphate lithium ion power battery and lithium ion battery: the price of lithium iron phosphate lithium ion power lithium battery is about 50% more expensive than that of ordinary lithium ion batteries. 10. The working temperature difference between lithium iron phosphate lithium ion power battery and lithium ion battery: Compared with the operating temperature of lithium ion battery, the working temperature of lithium iron phosphate lithium ion battery is higher, while the working temperature of lithium ion battery is higher. The ambient temperature should be relatively low by about 5 degrees. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
