New Zinc-Air Battery Is ‘Cheaper, Safer And Far Longer-Lasting Than Lithium-Ion’

The title of this post, is the same as that of this article on Recharge.

These are the first two paragraphs.

A new type of battery is coming onto the market that can store multiple days’ worth of energy, that doesn’t degrade, can’t possibly explode and is up to five times cheaper than lithium-ion, claimed its developer as it prepares to pilot the technology in New York state.

The zinc-air hybrid flow battery developed by Canadian company Zinc8 has the potential to disrupt the entire energy-storage market — making wind and solar farms baseload and even replacing the need for transmission grid upgrades in many places.

The article then gives an in depth review of Zinc8, its technology and its future prospects.

  • The Chief Executive is a former Canadian MP. Political connections help!
  • The company has $100million of funding.
  • Zinc8 energy storage systems are made larger by fitting and bigger storage tank and adding more electrolyte.
  • The capital cost of an eight-hour Zinc8 storage system is about $250/KWh, but this falls to $100/KWh for a 32-hour system and $60/KWh for a hundred-hour system.
  • Lithium-ion systems ttpically cost $300/KWh for any duration over eight hours.
  • The cost of Zinc8 systems is expected to fall as manufacturing increases.

The article finishes with a detailed description of how the technology works.

It also details the company’s growth strategy.

Conclusion

This technology looks like it will give lithiujm-ion batteries a good run for its money in grid storage applications and it could be one of those technologies that help the world to embrace renewable energy, like wind, solar and wave power.

It has various advantages.

  • Lower cost of installation.
  • Falling manufacturing cost.
  • Easily scalable.
  • No exotic or hazardous materials, just zinc, water and air, which are recycled.

My only worry, is that Zinc8, sounds too good to be true! But having met researchers at ICI, who were concerned in the birth of polythene, this could be a normal cynical reaction.

  1. All this talk of batteries reminds me of the old prank of sending a junior down to Woolworths to get a couple of AC batteries 🤣🤣

  2. These days power electronics effectively make an AC battery a practical proposition.

    There’s always the joke about two guys putting up a picture.

    One noticed his colleague was throwing away lots of nails and asked him, what was the problem.

    The reply was. “When I pick them up, the heads are on the wrong end.”

    So the first guy told him. “Don’t be silly! Those nails are for the other side of the room!”
