To this end, the combination of theory and experiment can help to accelerate scientific and technological development in batteries (Fig. 2) (7, 8). In particular, theory calculations can be used to guide the rational design of experiments, obviating the need for an Edisonian approach.
Analyzing the energetics of the overall cell reaction can also provide insights into how commercial batteries work and where their energy is stored. The most widely used household battery is the 1.5 V alkaline battery with zinc and manganese dioxide as the reactants. Six 1.5 V cells are also combined in series to produce a 9 V battery.
Indeed, metallic zinc is shown to be the high-energy material in the alkaline household battery. The lead–acid car battery is recognized as an ingenious device that splits water into 2 H + (aq) and O 2– during charging and derives much of its electrical energy from the formation of the strong O–H bonds of H 2 O during discharge.
Overall, successful integration of computations and experiments can help to establish a predictive framework to understand the complex electrochemical processes occurring in batteries, as well as uncover important underlying trends and common guiding principles in battery materials design.

As representative examples, when graphite anode is paired with LiCoO 2 and LiNi 1/3 Mn 1/3 Co 1/3 O 2 cathode, these batteries offer theoretical specific energies of 387 and 420 Wh kg −1, respectively (19, 20). Such lithium-ion chemistries have been the mainstream technology for portable electronics and electric vehicles.
