Maxell introduces a zero-mercury, zero-lead added silver-oxide cells

Connecticut, Louisiana, Maine, Rhode Island and Vermont will prohibit the shipment of standard silver-oxide batteries. Silver-oxide cells are the primary long-life cells used in wristwatches, and use silver-oxide for the cathode electrode, zinc for the anode electrode and an alkaline solution for the electrolyte. In conventional silver-oxide cells, small amounts of mercury and lead are used as an anti-corrosive. An anti-corrosive improves long-term reliability, while reducing the gas generation that follows the corrosion of the zinc in the anode and as a result of the local cell between the zinc and the surface area of the collector which contacts the zinc. Maxell has been able to achieve zero-mercury, zero-lead using an original new cathode anti-corrosion technology, along with a corrosion-resistant zinc alloy.

Maxell’s latest mercury free batteries draw on an ongoing commitment to developing and commercializing environmentally friendly products. Looking forward, Maxell will continue to pursue high–quality and environmentally conscious products and focus on developing technologies designed to reduce the environmental impact of its own products, and products used daily by consumers around the world.
