This paper proposed the global collaboration maps in order to help analyze and govern international collaboration. By analyzing the characteristics of maps that can be done by using some existing methodologies in the literature for network mapping and geographic overlay mapping, some methods in global collaboration maps are applied for the sake of displaying the global collaboration network on the global geographic map: ⑴ to overlay the collaboration network on the global geographic map in order to bridge the network map and the geographic map; ⑵ to scale the node seizes in order to reveal the number of collaboration; ⑶ to use edges to exhibit the fruitful collaborations. The simulation results of international collaboration analysis of lithium battery based on global collaboration maps of patent show: ⑴ it can vividly reveal that the core group of collaborating nations is dominated by the subsets of research-intensive North America, Western-European and Eastern-Asian; ⑵ it can help recognize that the six power nations are US, Germany, France, Japan, Korea and China; ⑶ it can exhibit that Centre Nat is champion and Univ Tsinghua is runner-up. Thus it can be seen that global collaboration maps may offer help in global collaboration analysis, global collaboration government, etc.
