Abstract
"BATERIAS SECUNDáRIAS DE LìTIO COM SEGURANçA E DESEMPENHO APERFEIçOADOS" Descreve-se um eletrodo obtido de borra de eletrodo compreendendo: (a) um material ativo de eletrodo capaz de intercalação/de-intercalação de lítio; e (b) partículas inorgânicas tendo condutividade de íons de lítio. Também é descrito um dispositivo eletroquímico incluindo o mesmo eletrodo. O dispositivo eletroquímico, usando tais partículas inorgânicas tendo condutividade de íons de lítio acrescentadas à borra de eletrodo, pode apresentar melhor segurança, enquanto minimizando a degradação da qualidade causada pelo uso de aditivos.
