What is the difference between iron lithium ion battery and lead-acid battery

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-ion battery is 3.2V, and the fully-charged voltage is 3.65V. The finished voltage is 2.0V. The voltage of lead-acid batteries is lower than that of iron-lithium-ion batteries, while the voltage of iron-lithium-ion batteries is slightly higher. 2. The electrodes of lead-acid batteries are mainly made of lead and its oxides, and the electrolyte is a kind of storage battery with sulfuric acid solution; in the discharge state of lead-acid batteries, the important component of the positive electrode is lead dioxide, and the important component of the negative electrode is lead; the state of charge Below, the important components of the positive and negative electrodes are lead sulfate, which is divided into vented batteries and maintenance-free lead-acid batteries. Lithium iron battery mainly uses lithium iron phosphate as the cathode material. The full name of iron lithium ion battery is lithium iron phosphate lithium ion battery. Because its performance is particularly suitable for power applications, it is also called lithium iron power lithium battery. 3. The production process of lead-acid batteries is to match gold, cast grids, smear (previously there should be lead powder and paste process), solidify, dry, slice and polish to match the group of packs and weld the shell, and the upper cover is sealed. Terminal welding, slotting, acid injection, formation, cleaning, warehousing, packaging and delivery, etc. The production process of iron-lithium ion batteries is batching, coating, rolling, slitting, sheeting, winding, assembly, and laser Welding, baking, liquid injection, activation, formation, sealing, cleaning, sorting, sorting, shipping, etc., the production process of iron-lithium ion 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-ion batteries can also be floated. Charging, especially in the application of emergency lights, many use floating charging, and the floating charging life is about 8 years. 5. Lead-acid batteries are divided into three categories: ordinary lead-acid batteries, dry-charge batteries, and maintenance-free batteries, while iron-lithium-ion batteries are mainly divided into polymer iron-lithium-ion batteries, cylindrical iron-lithium-ion batteries, and square iron-lithium-ion batteries. There are three major categories, lead-acid batteries and iron-lithium-ion batteries are basically classified into three categories, and their commonality is that they can be used for power. 6. Lead-acid batteries and iron-lithium-ion batteries are compared in terms of energy and volume. Generally, the weight of lead-acid batteries is about 16 kilograms, and the volume of lead-acid batteries is larger; while the weight of iron-lithium-ion batteries is generally about 3 kilograms, iron-lithium-ion batteries The volume is relatively small and easy to carry. 7. Comparison of the durability of lead-acid batteries and iron-lithium-ion 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, which consumes a period of time Later, if the battery is found to be hot or the charging time becomes short, it is necessary to replenish the liquid; while the lithium-ion 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.
