The Correct Option is A
Approach Solution - 1
To determine which metals are employed in the battery industries, we need to assess the given options. Batteries are commonly made using metals that provide good electron flow and stability. Let's examine the given options:
- Fe (Iron) - Though iron is used in many industrial applications, it is not typically used in battery manufacturing due to its tendency to corrode and not having the required electrochemical properties.
- Mn (Manganese) - Manganese is commonly used in batteries, particularly in alkaline batteries and lithium-ion batteries in the form of manganese dioxide.
- Ni (Nickel) - Nickel is widely used in various types of rechargeable batteries, including Nickel-Cadmium (NiCd) and Nickel-Metal Hydride (NiMH) batteries.
- Cr (Chromium) - Chromium is not commonly used in battery manufacturing. Its primary uses are in corrosion-resistant materials and stainless steel production.
- Cd (Cadmium) - Cadmium is used in rechargeable NiCd batteries. Despite the environmental concerns associated with cadmium, it is a key component in this type of battery.
Analyzing these facts, the metals used in battery industries from the given options are Manganese (Mn), Nickel (Ni), and Cadmium (Cd).
Therefore, the correct answer is: B, C, and E only.
