Which of the lead-acid batteries and lithium-ion batteries is cost-effective?

We first need to know what a lead-acid battery is. In fact, the lead-acid battery is a kind of electrode mainly made of lead and its oxide. Its electrolyte is sulfuric acid solution, the important component of the positive electrode is PbO2, and the important component of the negative electrode is lead. Like lithium-ion batteries, lead-acid batteries are also more severely affected by temperature. The service life of lead-acid batteries will increase with the increase in temperature, but will gradually decrease after being higher than 50 degrees Celsius. Also note that the nominal voltage of a single-cell lead-acid battery is 2.0V. In normal applications, a single lead-acid battery can be connected in series, such as a 12V, 24V or 36V lead-acid battery. However, lead-acid batteries have lower energy density and have a shorter service life than lithium-ion batteries. The energy density of current lithium-ion batteries is generally 200-260wh/g, and lead-acid is generally 50-70wh/g. Regarding new energy vehicles, especially pure electric vehicles, the energy density will affect the cruising range of the vehicle to a certain extent. So from this point of view, lithium-ion batteries are more cost-effective. In terms of service life, the number of full charge cycles of lithium-ion batteries is about 1,000 times, among which lithium iron phosphate batteries can be fully charged up to about 2,000 times. As for lead-acid batteries, the service life is relatively short, and the number of cycles to fully charge and discharge is basically about 300 to 350. Therefore, in terms of service life, lithium-ion batteries are also longer than lead-acid batteries. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
