LiFePO4, on the other hand, is inherently \u201cplagued\u201d by poor electronic and ionic conductivity. While the problems with low electron conductivity are partially solved by carbon coating and further by doping or by downsizing the active particles to nanoscale dimensions, poor ionic conductivity is still an issue. To develop colloidally synthesized LiFePO4 nanocrystals (NCs) optimized for high rate applications, we propose here a surface treatment of the NCs. The particles as delivered from the synthesis have a surface passivated with long chain organic surfactants, and therefore can be dispersed only in aprotic solvents such as chloroform or toluene. Glucose that is commonly used as carbon source for carbon-coating procedure is not soluble in these solvents, but it can be dissolved in water. In order to make the NCs hydrophilic, we treated them with lithium hexafluorophosphate (LiPF6), which removes the surfactant ligand shell while preserving the structural and morphological properties of the NCs. Only a roughening of the edges of NCs was observed due to a partial etching of their surface. Electrodes prepared from these platelet NCs (after carbon coating) delivered a capacity of \u223c155 mAh\/g, \u223c135 mAh\/g, and \u223c125 mAh\/g, at 1 C, 5 C, and 10 C, respectively, with significant capacity retention and remarkable rate capability. For example, at 61 C (10.3 A\/g), a capacity of \u223c70 mAh\/g was obtained, and at 122 C (20.7 A\/g), the capacity was \u223c30 mAh\/g. The rate capability and the ease of scalability in the preparation of these surface-treated nanoplatelets make them highly suitable as electrodes in Li-ion batteries.<\/jats:p>","DOI":"10.1021\/nl504093w","type":"journal-article","created":{"date-parts":[[2014,11,5]],"date-time":"2014-11-05T10:54:29Z","timestamp":1415184869000},"page":"6828-6835","source":"Crossref","is-referenced-by-count":61,"title":["Etched Colloidal LiFePO4 Nanoplatelets\ntoward High-Rate Capable Li-Ion Battery Electrodes"],"prefix":"10.1021","volume":"14","author":[{"given":"Andrea","family":"Paolella","sequence":"first","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]},{"name":"Institut de Recherche d\u2019Hydro-Que\u0301bec (IREQ) , 1800 Boulevard Lionel Boulet , , ,","place":["Varennes, QC, Canada, J3X1S1"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Bertoni","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]},{"name":"IMEM-CNR , Parco Area delle Scienze 37\/A , ,","place":["Parma, Italy, 43124"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergio","family":"Marras","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrico","family":"Dilena","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Massimo","family":"Colombo","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirko","family":"Prato","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Riedinger","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]},{"name":"ETH Zurich , , ,","place":["Zurich, Switzerland, 8092"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mauro","family":"Povia","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Ansaldo","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karim","family":"Zaghib","sequence":"additional","affiliation":[{"name":"Institut de Recherche d\u2019Hydro-Que\u0301bec (IREQ) , 1800 Boulevard Lionel Boulet , , ,","place":["Varennes, QC, Canada, J3X1S1"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liberato","family":"Manna","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chandramohan","family":"George","sequence":"additional","affiliation":[{"name":"Istituto Italiano di Tecnologia , , Via Morego 30 , ,","place":["Genova, Italy, 16163"]},{"name":"University of Cambridge Institute for Manufacturing, , , 17 Charles Babbage Road , ,","place":["Cambridge, United Kingdom, CB3 0FS"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2014,11,5]]},"reference":[{"key":"2026090201230812500_cit1","doi-asserted-by":"crossref","first-page":"1188","DOI":"10.1149\/1.1837571","article-title":"Phospho-olivines as positive-electrode\nmaterials for rechargeable lithium batteries","volume":"144","author":"Padhi","year":"1997","journal-title":"J.
