a) No many materials can be charged (a simple capacitor) and that's not electrochemical. b) Yes primary and storage refer to single use and rechargable, and these are electrochemical cells. The former is a one-way electrochemical reaction, and the latter is rechargable because the electrochemical reaction is reversable. c) No a solar cell isn't considered electrochemical d) No a lightning rod isn't electrochemical
