Devido a sua baixa resist\u00eancia interna, essas baterias s\u00e3o ideais para o arranque de carros e ve\u00edculos a diesel e gasolina. No entanto, elas apresentam uma vida \u00fatil limitada sob condi\u00e7\u00f5es de ciclos profundos, com aproximadamente 12 a 15 ciclos.<\/p>\n<h2>Outros Tipos de Baterias de Chumbo-\u00c1cido<\/h2>\n<p>Existem dois grupos principais de baterias de chumbo-\u00e1cido:<\/p>\n<ol>\n<li><strong>Bateria VLA (vented lead-acid battery)<\/strong>: Este tipo \u00e9 uma bateria de chumbo-\u00e1cido com eletr\u00f3lito l\u00edquido e ventilado, onde os eletrodos s\u00e3o submersos em excesso de eletr\u00f3lito l\u00edquido. Dentro das baterias VLA, encontramos grupos espec\u00edficos, como as baterias de tra\u00e7\u00e3o ou ciclo profundo, projetadas para descarga constante e pequena por longos per\u00edodos, sendo menos suscet\u00edveis \u00e0 degrada\u00e7\u00e3o devido ao ciclismo e utilizadas em sistemas fotovoltaicos e ve\u00edculos el\u00e9tricos.<\/li>\n<li><strong>Bateria VRLA (valve-regulated lead-acid battery)<\/strong>: S\u00e3o baterias seladas ou reguladas por v\u00e1lvula, onde o eletr\u00f3lito \u00e9 imobilizado em um separador absorvente ou em gel. H\u00e1 dois tipos principais de baterias VRLA:\n<ul>\n<li><em>AGM (Absorbent Glass Mat)<\/em>: Baterias AGM s\u00e3o um tipo de bateria de chumbo-\u00e1cido regulada por v\u00e1lvula que possui pequenos canais de g\u00e1s no eletr\u00f3lito, oferecendo maior densidade de energia e vida \u00fatil mais longa que as baterias de chumbo-\u00e1cido regulares.<\/li>\n<li><em>C\u00e9lula de Gel (bateria de gel)<\/em>: As baterias modernas de gel s\u00e3o baterias VRLA com eletr\u00f3lito gelificado, oferecendo maior resist\u00eancia ao choque e \u00e0 vibra\u00e7\u00e3o, al\u00e9m de reduzir a evapora\u00e7\u00e3o do eletr\u00f3lito e os problemas de corros\u00e3o comuns \u00e0s baterias \u00famidas.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<h2>Qu\u00edmica das Baterias de Chumbo-\u00c1cido: Funcionamento<\/h2>\n<p>O princ\u00edpio de opera\u00e7\u00e3o das baterias de chumbo-\u00e1cido \u00e9 ilustrado pelos processos qu\u00edmicos que ocorrem durante a carga e descarga. Durante a descarga, ocorre no \u00e2nodo a rea\u00e7\u00e3o <em>Pb + SO<sub>4<\/sub><sup>2-<\/sup> \u2192 PbSO<sub>4<\/sub> + 2e<sup>&#8211;<\/sup><\/em>, onde o chumbo \u00e9 oxidado com o eletr\u00f3lito para formar sulfato de chumbo, liberando dois el\u00e9trons. No c\u00e1todo, forma-se tamb\u00e9m sulfato de chumbo pela rea\u00e7\u00e3o: <em>PbO<sub>2<\/sub> + SO<sub>4<\/sub><sup>2-<\/sup> + 4H<sup>+<\/sup> + 2e<sup>&#8211;<\/sup> \u2192 PbSO<sub>4<\/sub> + 2H<sub>2<\/sub>O<\/em>. Durante a carga, os processos ocorrem em sentido inverso, reduzindo o sulfato de chumbo formado na descarga.<\/p>\n<p>Se o sulfato de chumbo for completamente consumido e o processo de carga n\u00e3o for interrompido, inicia-se a eletr\u00f3lise do eletr\u00f3lito. O sobrecarregamento com altas tens\u00f5es de carga gera g\u00e1s oxig\u00eanio e hidrog\u00eanio pela eletr\u00f3lise da \u00e1gua, que se perde em bolhas. Baterias seladas possuem catalisadores (Pd, Pt) acima da ventila\u00e7\u00e3o onde o g\u00e1s oxihidrog\u00eanio pode recombinar-se em \u00e1gua. A tens\u00e3o da c\u00e9lula resultante pode ser determinada pela s\u00e9rie galv\u00e2nica, sendo a tens\u00e3o total da rea\u00e7\u00e3o redox: <em>E<sub>0<\/sub> = 1.68V &#8211; (-0.36V) = 2.04V<\/em>.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.electricity-magnetism.org\/wp-content\/uploads\/2022\/09\/SLI-battery-characteristics.png\" alt=\"\" \/><\/p>\n<div style=\"text-align: center; font-size: 20px;\">\n    <a href=\"https:\/\/www.electricity-magnetism.org\/electric-battery\/sli-battery\/\">Original Article<\/a>\n<\/div>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>As baterias SLI s\u00e3o projetadas para fornecer a corrente m\u00e1xima em um curto espa\u00e7o de tempo, mantendo a tens\u00e3o constante, portanto, possuem uma resist\u00eancia interna muito baixa.<\/p>\n","protected":false},"author":1,"featured_media":4386,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_generate-full-width-content":"","footnotes":""},"categories":[14],"tags":[],"class_list":["post-80551","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-nao-categorizado","generate-columns","tablet-grid-50","mobile-grid-100","grid-parent","grid-50"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v17.9 -
