Can button cell battery production reduce mercury use?
Because button cells account for the bulk of mercury use in the battery sector, significant mercury reductions in this sector can only be achieved by phasing out mercury use in button cell battery production.
Why is mercury used in button batteries?
Historically, mercury has been used in button batteries to reduce hydrogen gas generated inside the battery because the elimination of mercury was considered technically impossible. Murata undertook the challenge of designing mercury-free silver oxide batteries to contribute to the protection of the environment and consumers.
Who makes mercury free silver oxide batteries?
Mercury free silver oxide batteries were introduced by SONY in 2005, and now SONY makes 34 different mercury free silver oxide models. Other manufacturers offering mercury free silver oxide batteries include Seiko, Maxell, Renata, Energizer, Duracell, and Rayovac.
