When Compact Size Matters, There’s Only One Logical Choice.

Silver-Zinc Begins Where Li-ion Leaves Off.

Li-ion batteries have enabled countless innovations since the 1990s, and they continue to be a vitally important component for hundreds of products. But they have serious limitations — primarily size, energy density and safety — that impede manufacturers from making smaller, safer products. Silver-zinc provides clear superiority for devices that require close physical contact with the user, and applications in which miniaturization is a prime consideration.

In addition to size and safety, silver-zinc microbatteries offer an array of benefits that include fewer shipping and handling restrictions, and environmental sustainability.

More Energy in Less Space.

Silver-zinc can deliver the same amount of energy as other batteries in a more compact space. This size advantage is further enhanced by its water-based chemistry, which alleviates the need for protective casings and packaging that increase bulk.
