Electrophoretic fabrication of LiCoO_2 positive electrodes for rechargeable lithium batteries

摘要

LiCoO_2 composite electrodes for rechargeable lithium batteries were fabricated by an electrophoretic deposition (EPD) method. LiCoO_2 oxide particles were deposited on anal current collector with appropriate amounts of Ketjen black and polytetrafluoroethylene (PTFE) by applying a high dc voltage between two electrodes in an EPD suspension. The density of the composite electrode was comparable with that for an electrode prepared by a conventional process.
