Textbooks are part of school life, and they are often the only didactic material used for teaching. Thus, constant monitoring of the contents and approaches presented in them is necessary, mainly on themes that involve more abstract concepts. This manuscript presents the results of bibliographical research that aimed to analyze works published in the literature that investigated how electrochemical cells are developed in textbooks. The bibliographic survey was carried out in Google Academic, Scielo, and Portal Capes databases. After applying selection and exclusion criteria, twelve publications were elected that constituted the corpus of this research. Discussions were based on four categories of analysis: Experimental Approach, STSE/Environmental Approach, Images and Representations, and Theoretical and Conceptual Approach. The results indicate that important aspects of teaching concepts of electrochemistry are deserving the attention of researchers, resulting in improved quality of content available in books. They also indicate obstacles that still need to be overcome, such as mistaken conceptual approaches, as in the concept of electrode potential, movement of ions and electrons in electrochemical cells; recurrent use of images for illustrative purposes only; and the occurrence of experimental proposals still with a procedural character in the analyzed books.
