The introduction of the Lead-acid batteries

A lead-acid battery (VRLA) is a battery whose electrode is mainly made of lead and its oxide, and the electrolyte is a sulfuric acid solution. When the lead-acid battery is discharged, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. In the state of charge, the main components of the positive and negative electrodes are lead sulfate.

A single-lead lead-acid battery has a nominal voltage of 2.0V, can be discharged to 1.5V, and can be charged to 2.4V. In applications, 6 single-cell lead-acid batteries are often used in series to form a 12V lead-acid battery. There are also 24V, 36V, 48V and so on.

Introduction

The French Prande invented the lead-acid battery in 1859, and has experienced nearly 150 years of development. In terms of theoretical research, lead-acid batteries have made great progress in terms of product types, varieties, and electrical properties of products, whether Lead-acid batteries play an indispensable role in transportation, communications, electric power, military or in various economic fields of navigation and aviation.

According to the difference in structure and use of lead-acid batteries, the batteries are roughly divided into four categories: 1. Lead-acid batteries for start-up; 2. Lead-acid batteries for power use; 3. Fixed-type valve-regulated sealed lead-acid batteries; Including small valve-regulated sealed lead-acid batteries, lead-acid batteries for miner's lamps, etc.

A single-cell lead-acid battery has a nominal voltage of 2.0V, can be discharged to 1.5V, and can be charged to 2.4V. In the application, six single-cell lead-acid batteries are often used in series to form a lead-acid battery nominally 12V. There are also 24V, 36V, 48V and so on.
