Abstract
We propose an unconventional method to obtain fine‐grained SnO2 and WO3 powders. It uses as precursors, polymer complexes between polyethylene oxide (POE) and SnCl4 or WCl6 respectively. By pyrolysis of these complexes in the 350‐550? temperature range, metal‐oxide powders possessing small crystallite sizes are obtained. They are free from water and hydroxyl group contaminations, which is an added advantage where the application of these materials to Li‐batteries is concerned. We have, indeed, demonstrated that these powders show good ability to insert reversibly lithium ions in the Li/ Li+/SnO2 (WO3) cells.Keywords
