    I wonder if it can be cheaper and better at scale than iron-air batteries. Those seem inexpensive to make, and can carry a large enough capacity if you put a whole lot of them in parallel with each other, and have a long lifetime. They’re just really heavy for their amount of energy density and fairly low current per cell, but that shouldn’t be a problem when building enough to be grid-scale.

      It depends on what you value. For performance and power density, nothing really beats lithium at the moment.

      However, for grid-scale battery these parameters are not necessarily very important. What matters most is cost over the lifetime, and that’s wher zinc batteries could be useful. They have the potential to be much cheaper than the cheapest lithium batteries.

      Energy density on these are woefully inadequate for cars, but that doesn’t matter for stationary storage which is what this is for.

        I’m more interested in how they will troubleshoot and perform preventative maintenance to the battery, since halides are quite toxic.
