BASIC BATTERY INFORMATION
Battery (Electrochemical Equipment)
The device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery for short. After discharging, the internal active material can be regenerated by charging-storing electric energy as chemical energy; when it needs to be discharged, the chemical energy is converted into electric energy again. This type of battery is called a storage battery, also called a secondary battery or a lead-acid storage battery.
The so-called battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.
A storage battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to recharge through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery , Belongs to the secondary battery. Its working principle: When charging, use external electric energy to regenerate internal active materials, store electric energy as chemical energy, and convert chemical energy into electric energy again when it needs to be discharged, such as cell phone batteries commonly used in life.
It uses a lead-based grid filled with spongy lead (also called a grid) as the negative electrode, and a lead-based grid filled with lead dioxide as the positive electrode, and uses dilute sulfuric acid with a density of 1.26--1.33g/ml/ml as the electrolyte. When the battery is discharging, metallic lead is the negative electrode and an oxidation reaction occurs to produce lead sulfate; the lead dioxide is the positive electrode and a reduction reaction occurs to produce lead sulfate. When the battery is charged with direct current, elemental lead and lead dioxide are respectively generated at the two poles. After removing the power source, it returns to the state before discharge to form a chemical battery. Lead storage batteries can be charged and discharged repeatedly. Its cell voltage is 2V. The battery is a battery pack composed of one or more cells, referred to as a storage battery. The most common is 6V, and there are 2V, 4V, 8V, 24V storage batteries. . For example, the battery used in the car (commonly known as the battery) is a 12V battery pack with 6 lead-acid batteries connected in series.
For traditional dry-charged lead batteries (such as car dry-charged batteries, motorcycle dry-charged batteries, etc.) after a period of use, distilled water should be added to keep the dilute sulfuric acid electrolyte at a density of about 1.28g/ml; for maintenance-free batteries, the There is no need to add distilled water until the end of life.
The above is a brief introduction to the basic information of batteries. We are a battery manufacturer and also produce many other products, such as: 12v Deep Cycle Gel Battery, etc. Welcome to visit our company!
