Copper – Zinc batteries which were manufactured initially were single-discharge cells which could not be recharged electrically. The cells were recharged physically with fresh chemicals. However, the UK based company has developed a patented system for making Copper/Zinc rechargeable using an ionically permeable separator.

There are various benefits of Copper/Zinc battery such as:

• Proven chemistry from mining industry
• Ambient operation
• Aqueous (not flow)
• Green – 99.5% recyclable
• Abundant, low-cost materials
• Automotive-style assembly
• Maintainable – 30 year life
• Round trip efficiency 80%+ ac/ac
