What is the difference between lead-acid batteries and lithium iron batteries?
1. Lead-acid battery single grid rated voltage 2.0 v, full voltage 2.4 v, discharge voltage 1.5 v, lithium iron battery rated voltage 3.2 v, full voltage 3.65 v, discharge voltage 2.0 v, lead-acid battery, and lithium iron The battery voltage is lower than the lead-acid voltage, and the lithium iron battery voltage is slightly higher.
2. The electrodes of lead-acid batteries are mainly composed of lead and its oxides. The electrolyte is a sulfuric acid solution battery. Lead-acid batteries, called lead-acid batteries in English, are mainly composed of lead dioxide in the positive electrode and lead in the negative electrode. Undercharging conditions, the main component of the positive and negative electrodes is lead sulfate. Divided into exhaust battery and maintenance-free lead-acid battery; lithium iron battery mainly uses lithium iron phosphate as the positive electrode material. The full name of lithium iron phosphate battery is lithium iron phosphate battery. Due to its performance, it is particularly suitable for power applications.
3. The production process of lead-acid batteries is related to gold, casting grids, smears (previously lead powder, paste process), curing, drying, chip gloss, and group, package block-a group of welding shells, sealing, terminal welding, inserting Grooving, acid injection, cleaning, storage, package delivery, etc., and production of lithium iron battery technology components, coating, rolling, cutting, production, winding, assembly, laser welding, baking, filling, activation, in lithium iron batteries In terms of production technology, Rabin, sealing, cleaning, capacity, sorting, and distribution are much more complicated than lead-acid batteries.
4. Lead-acid battery floating charging, lead-acid battery structure anticorrosive lead-calcium alloy railing, the battery can be used for floating charges for about 5 years, and iron-lithium batteries can also be used for floating charges in addition to normal charges, especially in emergency lamps Many of the applications use floating, and the floating charge lives in about 8 years.
5. Lead-acid batteries can be divided into three types: ordinary lead-acid batteries, dry batteries, and maintenance-free batteries, and lithium-ion batteries are divided into three types: polymer lithium-ion batteries, cylindrical lithium-ion batteries, and square lithium-iron batteries, lead-acid batteries There are three basic types of lithium-ion batteries and their ability to use together.
6. The energy and volume of lead-acid batteries are compared with iron-lithium batteries. 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 handle.
7. Comparison of durability between lead-acid batteries and iron-lithium batteries: lead-acid batteries are generally charged and discharged within 300 times, and the life of memory and lead-acid batteries is about 2 years. In addition, lead-acid batteries contain liquid. The lithium battery has strong durability, slow power consumption, more than 2000 times, and has no memory, and generally has a service life of more than 5 years.
