Flow batteries are not very different from the everyday batteries that we use. The big difference is that the energy is stored in two separate fluids with dissolved chemicals for charge storage.

Your thoughts, emotions and behaviours arise from the complex network of electric activity in your brain. But what can we do when we need to tweak it?
