1. Taking lithium iron phosphate as an example, the lithium iron phosphate power battery is mainly composed of lithium iron phosphate life cycle 4 peridot structure lithium battery anode material. A lithium iron phosphate power battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Ordinary lithium batteries are mainly composed of lithium manganate anode materials, mainly spinel-type lithium manganate materials. In 1981, Hunter prepared the spinel-type lithium manganate lithium salt anode material with three-dimensional lithium-ion channels for the first time. However, with the development trend of lithium battery anode materials, there may be more high-quality anode materials to replace current materials. However, the safe application of battery materials is more important.

2. Voltage difference between lithium iron phosphate battery and lithium battery: standard voltage of lithium iron phosphate battery platform is 3.2v, full charge 3.65v, lithium iron phosphate battery discharge cut-off voltage is 2.0v; while ordinary lithium battery platform voltage is 3.7v, fully charged The latter is 4.2v, and the battery discharge cut-off voltage is 2.7v. In contrast, the voltage of lithium batteries is higher than that of power batteries. Lithium iron phosphate can be overcharged and over-discharged, and overcharge can recover more than 80% in a short time. When the lithium-ion is overloaded at 2.6v, irreversible damage will occur.
3. Lithium ferric acid battery puncture will not cause fire or explosion, but normal lithium battery puncture will cause an explosion.
4. The lithium iron phosphate power battery will not catch fire when overcharged to 100%; an ordinary lithium battery will burst when it reaches the specified value.
5. Discharge performance difference between lithium iron phosphate power battery and lithium battery: Lithium iron phosphate power battery can support 30 c discharge rate and unsafe hidden dangers, some lithium iron phosphate batteries can reach 600 instantaneous currents, normal and ordinary lithium batteries support 3 c Discharge rate, the phenomenon of false death of continuous high current discharge battery occurs.

6. The weight difference between lithium iron phosphate power battery and lithium battery: The weight of a lithium iron phosphate power battery with the same volume is nearly twice that of an ordinary lithium battery.
7. The internal resistance difference between lithium iron phosphate power battery and lithium battery: The internal resistance of lithium iron phosphate power battery of the same volume is much smaller than that of an ordinary lithium battery.
8. The difference between capacity lithium iron phosphate power battery and lithium battery: The volume of the same capacity of lithium iron phosphate power battery is lower than that of ordinary lithium batteries, and the energy density of the battery is about 60% lower than that of ordinary lithium. battery.
9. The price difference between lithium iron phosphate batteries and lithium batteries: the price of lithium iron phosphate batteries is about 50% higher 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 iron phosphate power battery, the working temperature of lithium iron phosphate power battery is higher, while the working temperature of lithium battery is higher. The ambient temperature should be about 5 degrees lower.
Which is better, a lead-acid battery or a lithium iron phosphote battery?
1. Lithium-iron battery is light in weight and large in specific energy, but it is safe and cost-effective; the same lead-acid battery is small in weight, volume, and specific energy, but it is safe and cost-effective, so in this case, you are willing Choose lead-acid battery or iron-lithium battery?
2. Lithium-iron batteries are rechargeable batteries, and lead-acid batteries are alkaline batteries; the cycle life of iron-lithium batteries is more than 2500 times that of lithium batteries, and the cycle life of lead-acid batteries is about 800 times that of lithium batteries. The specific energy of lead-acid batteries is about 40W·h/kg. The charging time of iron-lithium batteries can be fully charged within 4h, while the charging time of lead-acid batteries is generally about 6h.
3. The charging and discharging power efficiency of lithium-ion batteries is more prominent. The charging and discharging power conversion efficiency of lithium-ion batteries can exceed 97%, while the charging and discharging power conversion efficiency of lead-acid batteries is about 80%, which is equivalent to that of lead-acid batteries. Lithium iron phosphate batteries are small, and the volume of lithium iron phosphate lithium-ion batteries is about two-thirds the size of lead-acid batteries.
