In principle, a battery seems to be a simple device since it just requires three basic components – two electrodes and an electrolyte – in contact with each other. However, only the control of the interplay of these components as well as their dynamics, in particular the chemical reactions, can yield a high-performance system.
where r is the distance from the scattering volume and γ the angle between the scattering direction and the direction of the vibration, i.e. the electric field vector. For the vibrational component that is perpendicular to the scattering plane, γ remains unchanged (90 ), while for the parallel component, γ is complementary to the scattering angle θ (γ = 90 − θ).
