Regulation involves the implementation of laws and guidelines governing the production, usage, and disposal of batteries. These rules ensure safety, environmental protection, and fair market practices. For example, the European Union's Battery Directive mandates specific recycling rates for battery materials and requires manufacturers to comply with labeling and performance standards to reduce environmental impact and enhance consumer safety. In the United States, the Battery Act (Battery Management and Recovery Act) sets forth guidelines for battery recycling and disposal, aiming to minimize environmental hazards and promote the safe handling of batteries throughout their lifecycle.
