What type of battery contains no free or liquid electrolyte?

• A. Wet-cell battery
• B. Dry-cell battery
• C. Gel battery
• D. Flow battery

Answer: (B)

A dry-cell battery is characterized by the absence of free or liquid electrolyte, which distinguishes it from other types of batteries. In a dry-cell battery, the electrolyte is typically in a paste form, enabling it to maintain its shape and preventing leakage. This design is advantageous for portability and convenience, as it allows for use in a variety of applications, including small electronic devices like flashlights and toys. The dry-cell battery operates on the principle of converting chemical energy into electrical energy through electrochemical reactions, utilizing materials such as zinc and manganese dioxide. The solid or semi-solid electrolyte helps in preventing spillage while still allowing for efficient ion movement during the battery's operation. Other types of batteries, such as wet-cell batteries, contain a liquid electrolyte that can slosh around, posing risks of leakage and making them less suitable for portable uses. Gel batteries combine elements of both wet and dry technology, incorporating a gel-like electrolyte to reduce leakage, but they still do contain an electrolyte in a semi-liquid state. Flow batteries rely on liquid electrolytes that flow through the system, making them completely different from dry-cell technology.
