Detailed explanation of lead-acid batteries for electric vehicle batteries

Lead-acid batteries have the lowest price and are the most commonly used. my country is the world's largest processing country for lead-acid batteries. It contains less contaminated components and has good recyclability. The disadvantage is that it is smaller than the volume. In other words, under the same capacity, the weight and volume of the battery are large. The current lead-acid batteries are basically developed from floating-charge batteries. Floating charge batteries are not suitable for fast charging and high current discharge. Although technicians have spent a lot of effort to make effective improvements and can be put into practical use, their lifespan is still very unsatisfactory. Gel batteries belong to a development category of lead-acid batteries. The simplest method is to add a gelling agent to sulfuric acid to make the sulfuric acid electro-liquid become colloidal. Batteries in which the electro-hydraulic is in a gel state are usually called gel batteries. Broadly speaking, the difference between gel batteries and conventional lead-acid batteries is not only that the electro-hydraulic is changed to gel. For example, non-solid hydrocolloids belong to colloidal batteries from the perspective of electrochemical classification structure and characteristics. Another example is the attachment of polymer materials in the grid, commonly known as ceramic grids, which can also be regarded as a feature of gel batteries. The difference between the gel battery and the conventional lead-acid battery is from the initial understanding of electrolyte gelation to the study of the electrochemical characteristics of the electrolyte basic structure, as well as the use and promotion of grids and active materials. Its most important feature is: with a relatively small industrial cost, along the 150-year-old lead-acid battery industry road to produce higher-quality batteries, the discharge curve is straight, the inflection point is high, and the specific energy, especially the specific power, is better. Conventional lead-acid batteries are more than 20% larger, and their lifespan is generally about twice as long as conventional lead-acid batteries, and their high-temperature and low-temperature characteristics are much better.
