Part 7/10:
While progress is promising, TUM's zinc-ion technology remains in the lab stage, currently at a Technology Readiness Level (TRL) of 4. Before becoming commercially viable, the technology must overcome challenges related to scaling up production while maintaining cost-effectiveness. Nevertheless, there is optimism that as renewable energy demands grow, so too will the necessity for efficient storage solutions. Zinc-based batteries have already begun making strides in grid-scale energy storage, catering to the need for capturing intermittent renewable energy sources like solar and wind.
