If ΔH rxn is negative, then the enthalpy of the products is less than the enthalpy of the reactants; that is, an exothermic reaction is energetically downhill (part (a) in Figure 5.4.2). Conversely, if ΔH rxn is positive, then the enthalpy of the products is greater than the enthalpy of the reactants; thus, an endothermic reaction is energetically uphill …

For power storage, "Lithium-ion is the 800-pound gorilla," says Michael Burz, CEO of EnZinc, a zinc battery startup. But lithium, a relatively rare metal that's only mined in a handful of countries, is too scarce and expensive to back up the world's utility grids. (It's also in demand from automakers for electric vehicles.)
