Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a high-temperature-resistant valve-regulated lead-acid battery and a method for manufacturing the positive plate thereof. Background technique [0002] Lead-acid battery has experienced nearly 150 years of development history since the Frenchman Plante invented it in 1859. It is often used in transportation, communication, electric power, military, navigation and other fields and plays a very important role. In the prior art, when the lead-acid battery is in an environment greater than 35°C, the life of the battery will be doubled every time the temperature rises by 10 degrees. The formed mud is softened and easy to fall off, which makes the positive plate invalid, and the service life of the positive plate is the main factor affecting the battery life; 2. The failure of the positive active material further increases the internal resistance of the battery, making the ...
