Abstract
A mesoscopic form of the spinel LiMn2O4 has been synthesized and studied fo r its electrochemical performance as a lithium ion insertion host material and for its application in the electrode fabrication destined for rechargea ble batteries. A theoretical model based on the sintering behavior of sever al commercial materials indicated the major importance of controlling the p article size and the morphology of the agglomerates with respect to power d ensity and fast lithium intercalation in a prospective thin-layer battery s ystem. Computational models were developed for complete mesoporous thin-lay er cell simulation at steady state, providing insight to the requirements c oncerning the electrolyte function in the 'rocking-chair' concept scale-up. A complete thin-layer battery was conceived and constructed which showed p romising performance. (C) 1999 Elsevier Science S.A. All rights reserved.
