The main objective of this paper is, based on the theory of complex systems (Arthur, 2009), to reconstruct the inventive activity of lead-acid batteries used in electric vehicles. Based on the information from the United States Patent and Trademark Office (USPTO) database, and based on the methodology developed by Strumsky and Lobo (2015), it is possible to represent different degrees of inventive novelty (origination, new combination, recombination and reuse), as well as measuring the increasing technological complexity of lead-acid batteries. Evidence shows that the lead-acid battery is an increasingly complex technology. It is a rival technology but is also complementary to the nickel-metal-hydride and lithium-ion batteries used by electric and hybrid vehicles. [ABSTRACT FROM AUTHOR]

This article analyzes the actual conflict related to the Lithium mines in the northwest area of Argentina. Lithium is a key resource for technologic development, especially regarding the implementation of the electric car. In this context, native population of the region is threatened because their lands are the world biggest lithium deposit. ¿Does development justifies harming traditions of minorities?

The current global energy system is characterized by a high dependence on fossil fuels, a paradigm that begins to encounter difficulties as existing reserves are depleted and ecological costs increase. Thus, the incorporation of renewable energies, their generation in a distributed form and the growth of the electric motor park, are presented as the most promising triad in the conformation of a new, more efficient and sustainable paradigm. This article focuses on the importance that energy accumulators acquire in this scenario, mainly due to their role in stabilizing networks and enabling self-consumption and electric propulsion. It identifies lithium-ion batteries with a wide range of possibilities for South America, which has the most important reserves of lithium in the world, incorporating the idea of development within the new energy pattern and in a current and potential market of large dimensions.
