Overpotential in a Porous Electrode

During the galvanostatic discharge of porous electrodes in the absence of concentration gradients, overpotential is governed by the following equation  

8 Laplace Transform Technique for Partial Differential Equations 

In all the examples discussed in this chapter until now, the roots of q(s) were obtained analytically. This is not always possible. Often the roots should be obtained numerically as in section 7.1.4. This is illustrated in the next example.
