Occupational Safety Training for Battery Manufacturing

1. Overview of Batteries

a. What is a Battery?

A battery is an electrochemical energy storage device composed of cells, used to supply power for mobile devices, electric vehicles, uninterruptible power supplies (UPS), and many other applications. The primary function of a battery is to store energy chemically and convert it into electrical energy when needed.

Batteries are typically made up of one or more electrochemical cells enclosed in a leak-proof casing. These electrochemical cells contain electrodes — a positive electrode and a negative electrode — immersed in an electrolyte solution (such as sulfuric acid in lead-acid batteries). When connected in a circuit, an electrochemical reaction occurs between the electrodes to generate electrical current.

Common types of batteries include:

• Lead-acid batteries: Widely used in cars, motorcycles, UPS systems, and other household devices.
• Lithium-ion batteries: Used in mobile devices such as smartphones, laptops, tablets, and electric vehicles.
• Nickel-metal hydride batteries: Commonly found in consumer electronics like cameras and electronic toys.

Each type of battery has different characteristics in terms of capacity, lifespan, and performance, suitable for specific applications. Proper management and maintenance of batteries are essential to ensure their longevity and performance.

b. Machinery for Battery Production

• Moulding machines: Used to shape plastic or metal parts of batteries. For example, these machines can mold battery casings from heat-resistant plastic.
• Wrapping machines: Used to wrap protective and insulating layers around batteries to safeguard and enhance the safety of the final product.
• Electrolyte filling machines: Machines that fill electrolyte solutions (such as sulfuric acid) into batteries.
• Assembly machines: Used to assemble the components of batteries, including electrodes, conductors, and other parts.
• Testing and inspection machines: Equipment used to check the quality and performance of batteries after production to ensure they meet safety and quality standards.
