What are the differences between lead-acid batteries and iron-lithium batteries

1. The nominal voltage of a lead-acid battery cell is 2.0V, the fully charged voltage is 2.4V, and the discharged voltage is 1.5V, while the nominal voltage of the iron-lithium battery is 3.2V, and the fully charged voltage is 3.65V. The electric voltage is 2.0V. The voltage of lead-acid batteries is lower than that of iron-lithium batteries, while the voltage of iron-lithium batteries is slightly higher. 2. The electrodes of lead-acid batteries are made of lead and its oxides. The electrolyte is a kind of storage battery with sulfuric acid solution; the English name of lead-acid batteries is Lead-acid battery. In the state of discharge, the main component of the positive electrode is lead dioxide and the negative electrode. The critical component is lead; in the charged state, the critical components of the positive and negative electrodes are lead sulfate. It is divided into exhaust-type batteries and maintenance-free lead-acid batteries; iron-lithium batteries use lithium iron phosphate as the positive electrode material. The full name of iron-lithium batteries is lithium iron phosphate batteries. Because of their performance, they are particularly suitable for power applications. Some people call it lithium-iron power lithium-ion battery, and the English name of iron-lithium battery is LiFePO4battery. 3. The processing technology of lead-acid battery is to match gold, cast grid, smear (previously there should be lead powder and paste process), solidify, dry, slicing, polishing, grouping, welding, packing, and sealing the upper cover. Terminal welding, slotting, acid injection, formation, cleaning, storage, packaging and delivery, etc. The processing technology of iron-lithium batteries is batching, coating, rolling, slitting, sheeting, winding, assembly, and laser welding. , Baking, liquid injection, activation, formation, sealing, cleaning, volume sorting, sorting, shipping, etc. The processing technology of iron-lithium batteries is much more complicated than that of lead-acid batteries. 4. Lead-acid batteries have a lot of floating charge. Lead-acid batteries use lead-calcium alloy fences with anti-corrosion structure. The batteries can be used for floating charge for about 5 years. In addition to normal charging, iron-lithium batteries can also be used for floating charge. , Especially in the application of emergency lights, many of them use floating charge, and the life of the floating charge is about 8 years. 5. Lead-acid batteries are divided into three categories: general lead-acid batteries, dry-charge batteries, and maintenance-free batteries, while iron-lithium batteries are mainly divided into polymer iron-lithium batteries, cylindrical iron-lithium batteries, and square iron-lithium batteries. , Lead-acid batteries and iron-lithium batteries basically have three categories, and their commonality is that they can be used for power. 6. Lead-acid batteries and iron-lithium batteries are compared in terms of energy and volume. Generally, the weight of lead-acid batteries is about 16 kg, and the volume of lead-acid batteries is larger; while the weight of iron-lithium batteries is generally about 3 kg, and the volume of iron-lithium batteries is relatively large. Small and easy to carry. 7. Comparison of the durability of lead-acid batteries and iron-lithium batteries: lead-acid batteries are generally deep-charged and discharged within 300 times, have memory and the life of lead-acid batteries is about two years, and there is liquid in the lead-acid batteries, after a period of consumption If you find that the battery is hot or the charging time becomes shorter, you must add liquid; while the lithium battery has strong durability, slow consumption, more than 2000 charging and discharging times, and no memory, and the general life span is more than 5 years.
