What are the advantages and disadvantages of lead-acid batteries compared to lithium batteries?

The advantages and disadvantages of lead-acid batteries: Lead-acid batteries are batteries whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of a lead-acid battery, the important component of the positive electrode is lead dioxide, and the important component of the negative electrode is lead; in the charged state, the important components of the positive and negative electrodes are lead sulfate. At present, some RV manufacturers use lead-acid batteries or gel batteries as the living batteries of RVs. Among them, the most used deep-cycle lead-acid batteries can discharge the power very low without affecting the battery life, but this kind of battery is related to lithium As for batteries, there are shortcomings of power storage, and the volume and weight of lead-acid batteries are very large, and the weight is generally 16-30kg. Because lead-acid batteries and gel batteries have a history of 150 years of development, their safety has been widely recognized, and because of the short development time of lithium batteries, there are still many uncertainties, especially in the application of RVs. Advantages and disadvantages of lithium batteries: Compared with traditional lead-acid batteries, lithium batteries have obvious advantages in terms of charge and discharge power efficiency, power storage, volume, and weight, but they also have obvious disadvantages: high price and low stability. The price of lithium batteries is generally 3 to 4 times that of lead-acid batteries, but it is still acceptable for users who buy hundreds of thousands of RVs. What is really worrying is its stability. Domestic RVs use lithium batteries to catch fire from time to time, which makes many people's attitudes towards lithium batteries vague. The best operating temperature of lithium battery is 15~30℃. If the working temperature exceeds 35℃, its performance will drop sharply, or even crash; when the working temperature is lower than 5℃, the charging power of the battery will be greatly reduced, even at 0℃ The following situations may not be able to charge, and if the charging time is too long, the battery will experience lithium evolution, which may cause safety hazards such as a short circuit in the battery cell. Although the previous article has always emphasized the various instabilities of lithium batteries, as long as they are installed and used properly, the accident rate of lithium batteries is still within a controllable range. This is also the reason why many RV refitting plants dare to use it, and for large RV manufacturers, even an accident rate of one in ten thousand is a very terrible thing. Most users are not concerned about such a low accident rate. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
