Abstract: The technological trajectory of lithium battery manufacturing (LBM-Tra) provides valuable insights for managers and policymakers. However, current methods face difficulties in comprehensively understanding the diverse technological categories and intricate interconnections within LBM.
The rapid growth of the electric vehicle (EV) market has fueled intense research and development efforts to improve battery technologies, which are key to enhancing EV performance and driving range.
Effectively collecting information of battery technologies is the first step to analyse, group, evaluate and forecast battery integration mode. It is estimated that patents contain >90% technical information and that effective use of patents would shorten 60 and 40% of research and development (R&D) time and cost, respectively [18, 19].

Lithium-ion battery (LIB) is one of rechargeable battery types in which lithium ions move from the negative electrode (anode) to the positive electrode (cathode) during discharge, and back when charging. It is the most popular choice for consumer electronics applications mainly due to high-energy density, longer cycle and shelf life, and no memory effect.

The amount of the application of a certain patent represents the degree of social concern for the battery technology to some extent. It can be found that the R&D activities of the battery technology in current are mainly concentrated in three areas: fuel batteries, lead-acid batteries, lithium ion batteries.
Patent analysis is a powerful means to inform technology life cycle and forecast upcoming innovations. To date, only a handful of research have quantitatively analysed and compared battery assembly in the EV field, resulting in a lack of information to discern the battery layout.
Because the term ‘lithium-ion batteries’ was not recorded until the commercialization of Li-ion batteries by Sony, we combined the formula of TS = (cell% OR secondary batter* OR batter* OR accumulator OR rechargeable batter*), IPC code and keywords to search for patents, and then manually added these patents in corresponding battery levels.
Analysis of R&D cooperation in EV battery technology Patent inventor refers to the specific application of the patent. The applicant and the inventor of patent can be one or more, thus there is such a situation which the applicants or the inventors are in common.
It can be found that the R&D activities of the battery technology in current are mainly concentrated in three areas: fuel batteries, lead-acid batteries, lithium ion batteries. Qianqian Zhang et al. / Energy Procedia 105 ( 2017 ) 4274 – 4280 4277 Fig.3.
But its analysis mainly aimed at the EV specific technical areas, which is lacking of the overall understanding and R&D trend analysis. Therefore, based on the relevant data collected from the patent of EV battery, this paper tries to build a systematic analysis of the development condition and trend of battery technology.
