Abstract

Rechargeable lithium batteries are a key component of the global value chain of this chemical element. They have revolutionized different industries in the world (such as the automotive industry), with the intention of reducing the greenhouse effect and combating climate change. The aim of this research is to know the positioning of leading countries in the technology generation of lithium rechargeable batteries and the existing geo-strategic support between them. To achieve this purpose, we created and applied a new linear index to determine the technology regimes and the application of other known indexes (related to attractiveness, specialization and benchmarking) linked to technology generation in lithium batteries from 1993 to 2015. The main results show that China is oriented to technological regimes and that the USA, Germany, South Korea, and Japan are focused on scientific regimes, and the consequences of these regimes are a direct technological competition between China and South Korea (this last country supported by Germany and Japan).

Notes

  1. For the rest of this study, the terms lithium secondary batteries and lithium rechargeable batteries will be used interchangeably.

  2. The lithium primary batteries are non-rechargeable batteries. They are not addressed in this research.

  3. The results of TSLCI can be negative, when the economy is technology-based; zero (indifferent); or positive, when it is science-based. It is clarified that the first outcome occurs when the degree of scientific linkages of all the participating economies in the global technological generation (which is on the right side of the parenthesis) is higher than the degree of scientific linkages of a specific technology of an economy (which is on the left side of the same parenthesis). The second happens when the right and left sides of the parenthesis are equal. The third occurs when the average on the right side of the parenthesis is lower than the left side of this one. Additionally, it is clarified that the number 100 on the left side of the formula is to record everything in percentage terms (although, for cluster analyses, depending on the scale of the other variable (s), the TSLCI scale has been used in proportions, even when the percentage scale has been maintained in the graphs).

  4. The results of RGR can be a negative numerator and a negative denominator that indicate that technology j and all technologies of the world do not grow; a positive numerator and a negative denominator that gives a negative outcome that indicates that technology j grows but not all technologies; a negative numerator and a positive denominator that gives a negative outcome that indicates that the technology j does not grow but all technologies of the world do; a positive numerator < a positive denominator, whose meaning is that the growth of technology j is less than all the technologies of the world; a positive numerator = a positive denominator that gives an outcome equal to 1, whose meaning is that growth of the technology j is equal to the growth of all the technologies of the world; a positive numerator > a positive denominator that gives a result higher than 1, whose meaning is that technology j is more attractive than all the technologies of the world.

  5. If the RTA is higher than or equal to 1, it means that the economy has revealed technological advantages and is specialized; but if the RTA is less than 1, the economy is not specialized.
