> Production of batteries may grow in the future, To me it seems reasonable to assume that not only will battery consumption grow, it will grow exponentially (over the medium term - say the next 10 - 50 years). Rationale: - There is high demand - The production process is well established technology that can be easily replicated - There are no obvious limits to growth in the medium term (In the short-term there are resource constraints as mines are opened).
