Separator
A Separator is a crucial component in battery manufacturing that acts like a barrier between the positive and negative parts of a battery. Think of it as a safety wall that prevents the battery from short-circuiting while still allowing the necessary chemical reactions to occur. It's similar to a specialized filter or membrane, and it's essential for all types of rechargeable batteries, from phones to electric vehicles. When reviewing resumes, you might see this term used in contexts related to battery production, quality control, or research and development roles.
