The amount of carbon in these composites is less than 6.8 wt.%, and the X-ray diffraction experiment confirms that all samples are pure single phase indexed with the orthorhombic Pnma space group. The particle size of the LiFePO<jats:sub>4<\/jats:sub>\/C synthesized by acetic acid as a complexing agent is very fine with a size of 200 nm. The electrochemical performance of this material, including reversible capacity, cycle number, and charge-discharge characteristics, is better than those of LiFePO<jats:sub>4<\/jats:sub>\/C synthesized by other complexing agents. The cell of this sample can deliver a discharge capacity of 161.1 mAh g<jats:sup>-1<\/jats:sup> at the first cycle. After 30 cycles, the capacity decreases to 157.5 mAh g<jats:sup>-1<\/jats:sup>, and the capacity fading rate is 2.2%. The mechanism is studied to explain the effect of a complexing agent on the synthesis of LiFePO<jats:sub>4<\/jats:sub>\/C by sol-gel method. The results show that the complexing agent with a low stability constant may be proper for the synthetic process of LiFePO<jats:sub>4<\/jats:sub>\/C via sol-gel method.<\/jats:p>","DOI":"10.1186\/1556-276x-7-40","type":"journal-article","created":{"date-parts":[[2012,1,6]],"date-time":"2012-01-06T07:56:00Z","timestamp":1325836560000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effect of complexing agents on the electrochemical performance of LiFePO4\/C prepared by sol-gel method"],"prefix":"10.1186","volume":"7","author":[{"given":"Rong","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erwei","family":"Kang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bailing","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jou-Hyeon","family":"Ahn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2012,1,5]]},"reference":[{"key":"743_CR1","doi-asserted-by":"publisher","first-page":"1188","DOI":"10.1149\/1.1837571","volume":"144","author":"AK Padhi","year":"1997","unstructured":"Padhi AK, Nanjundaswamy KS, Goodenough JB: Phospho-olivines as positive electrode materials for rechargeable lithium batteries.
