Las fuentes de novedad inventiva en las baterías de plomo-ácido de los vehículos eléctricos.

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]
