Abstract

"ELETRODO PARA BATERIA SECUNDÁRIA DE LÍTIO". É descrito um eletrodo compreendendo um composto de nitrilo alifático, onde o composto de nitrilo alifático recobre uma superfície do eletrodo ou é incorporado nos materiais ativos do eletrodo. É descrita também uma bateria secundária de lítio tendo o dito eletrodo. A bateria secundária de lítio tem excelente segurança para prevenir ignição e explosão geradas quando a temperatura interna da bateria aumenta devido a emissão de calor causada pela reação de um eletrólito com um catodo, e o colapso estrutural de um catodo que ocorre sobrecarga. Adicionalmente, também é possível prevenir ignição e explosão quando a bateria é exposta a alta temperatura devido a um aumento na temperatura resultando de aquecimento ou curto-circuito local causado por impactos físicos. Além disso, é possível resolver os problemas de aumento de viscosidade e degradação de desempenho da bateria a baixa temperatura, que ocorrem quando um composto de nitrilo alifático é usado como um aditivo para o eletrólito.
