      abstract     = {The investigation of high-performance materials represents
                      an essential step in the battery industry to develop
                      innovative technologies. While patent analysis could help
                      promote research and development $(R\&D)$ by providing
                      insights into innovative activities, the significance of
                      material information contained in patent documents for the
                      advancement of battery technologies has not yet been
                      investigated. This study explored the potential of material
                      information derived from patent data for analyzing the
                      patent landscape by introducing a novel analysis framework.
                      It uses patent claims collected between 2010 and 2021 from
                      the domain of solid-state battery technology to extract and
                      transform material information. This study relies on 1-mode
                      network analysis to construct a material network and a
                      2-mode network analysis is applied to quantify the extent of
                      the chemical portfolios of assignees. The results indicate
                      that the polymer-based electrolytes are highlighted as the
                      dominant type in the solid-state batteries. A glance at the
                      chemical portfolios of assignees reveals a heterogeneous
                      technology profile, pointing to a highly diversified
                      material knowledge across several industries. The proposed
                      analysis framework is expected to offer a new empirical
                      perspective on the patent landscape in the battery sector by
                      exploiting material information. Broadening the view of
                      material research within the battery sector can support
                      $R\&D$ managers and research scientists in the design of
                      improved material search strategies and the selection of
                      appropriate collaborations partners for the respective
                      process.},
