Li2−xNaxFe0.5Mn0.5SiO4/C composites have been synthesized via a refluxing-assisted solid-state reaction. They can be well indexed as two mixed polymorphs with P21 and Pmn21. Na-doping can significantly improve the capacity and the rate capability.

Li2MSiO4(M=Mn, Co, Ni) is a potential high capacity cathode material because of its outstanding properties that exchange of two electrons per transition metal atom is possible and the theoretical capacity of Li2MSiO4 can reach as high as 330 mAhg-1. In this family, the cathode performance of Li2MnSiO4 synthesized by solution route has been published recently. However, it seems that the cycle life of Li2MnSiO4 fell short of our expectation. In this work, the Li2Mn0.7Fe0.3SiO4 cathode material was synthesized by traditional solid-state reaction method. The prepared powder was consisted of majority of Li2Mn0.7Fe0.3SiO4 and minor impurities which were examined by XRD. FESEM morphology showed that the products of Li2Mn0.7Fe0.3SiO4 and Li2MnSiO4 have similar particle size (about 50-300 nm). The electrochemical performance of Li2Mn0.7Fe0.3SiO4, especially for reversible capacity and cycle life, exhibited better than those of Li2MnSiO4.

Although many routes have been developed that can efficiently improve the electrochemical performance of LiFePO4 cathodes, few of them meet the urgent industrial requirements of large-scale production, low cost and excellent performance.

LiFePO4 was prepared using recovered materials from waste Li-ion battery. The recovered materials after treatment was mixed with Li2CO3, Fe (NO3) 3·9H2O and NH4H2PO4 to adjust the Li/Fe/P molar ratio equal to 1.05/1/1. The raw material was mixed with super-p and calcined in muffle to get LiFePO4 by a solid-state reaction. Optimal conditions were: 700°C, N2 ambience, 10h, and Fe/C=1/1.5 (mol). The characterization results showed that the product was irregular particles with size 5-10μm and good dispersion. When discharged in the range of 2.2~4.2V, the initial discharge capacity was 141.4mAh/g at 0.1C, 103.1mAh/g at 1C. The capacity retention was 97.2% after 300 cycles at 1C showing satisfactory stability.
