Divergent thinking plays an important role to enhance innovation ability of researchers. Divergent thinking is beneficial for inspiring people's creativity, breaking fixed thinking and proposing a variety of innovative method to improve efficiency of solving problem. Training divergent thinking can be applied on preparation of biomass carbon electrodes. Divergent thinking methods are divided into seven parts in this paper. They are materials divergent method, structure divergent method, function divergent method, morphology divergent method, combination divergent method, method divergent method and causality divergent method, respectively. These methods represent biomass carbon materials have composition, structure and function diversities. These materials can be applied to different battery systems. The introduction of seven methods provides reference for the preparation of carbon electrode materials for researchers, which proves the importance of training divergent thinking simultaneously.

发散思维对于提高研究人员的创新能力起着重要作用。发散思维有利于激发人们的创造力，打破固定思维并提出各种创新方法来提高解决问题的效率。训练分歧的思维可以应用于生物质碳电极的制备。本文将发散思维方法分为七个部分。它们分别是材料散布法，结构散布法，功能散布法，形态散布法，组合散布法，方法散布法和因果散布法。这些方法代表了生物质碳材料具有组成，结构和功能的多样性。这些材料可以应用于不同的电池系统。
