We have focused our attention on Volta s works which were organized in Le Opere di Alessandro Volta, published between 1918-1929, in which we may find memoirs, letters, texts, articles and manuscripts. We have showed indications that the battery was presented in 1800 to make public the contact theory in opposition to the animal electricity theory proposed for some of Volta s contemporaries. Regarding this, we sought to analyze some reasons that could have stimulated Volta to propose his theory as well as to present some Volta s theoretical assumptions which led him to formulate it. Furthermore, to conclude this work, we have tried to analyze the spread of Volta s theory departing from some opinions of his contemporaries and of other historians of science / O propósito desta dissertação é analisar determinados aspectos da teoria de contato de Alessandro Volta (1745-1827), focalizando, especialmente, as observações voltianas relativa à construção da pilha. Para tanto, partimos de algumas considerações acerca da obra Le Opere di Alessandro Volta, que foi publicada entre 1918-1927, reunindo memórias, cartas, textos, artigos publicados e manuscritos. Procuramos apontar para o fato de que a pilha foi apresentada em 1800 com o intuito de divulgar a teoria de contato e contrapor-se à teoria da eletricidade animal proposta por alguns contemporâneos de Volta. Desse modo, procuramos analisar as possíveis razões que motivaram Volta a propor a teoria de contato, bem como apresentar alguns pressupostos teóricos, que permearam a sua elaboração. Quanto à divulgação da teoria, procuramos abordá-la a partir de algumas opiniões tecidas pelos contemporâneos de Volta e de historiadores da ciência para, enfim, concluirmos esta pesquisa.
