Effect of preparation temperature and cycling voltage range on molten salt method prepared SnO2

Author: Reddy, MV ; Andreea, LYT ; Ling, AY ; Hwee, JNC ; Lin, CA ; Admas, S ; Loh, KP ; Mathe, Mahlanyane K ; Ozoemena, KI ; Chowdari, BVR Date: Sep 2013 We prepared nano-sized tin (IV) oxide (SnO(sub2)) via molten-salt technique: heating a mixture of tin tetrachloride, lithium nitrate and lithium chloride at 280 °C in air. The powders are characterized by X-ray diffraction and transmission ... Read more
Gel-combustion synthesized vanadium pentoxide nanowire clusters as cathode material for rechargeable lithium-ion batteries

Author: Ramasami, AK ; Reddy, MV ; Nithyadharseni, P ; Chowdari, BVR ; Balakrishna, GR Date: Feb 2017 Gel-combustion by a bio-fuel, processed starch of the root tuber of cassava (Manihot esculenta), was used to prepare vanadium pentoxide nanowire clusters (V2O5NWC). The as-synthesized product was characterized by X-ray diffraction (XRD), ... Read more
Low temperature molten salt synthesis of Y(sub2)Sn(sub2)O(sub7) anode material for lithium ion batteries

Author: Nithyadharseni, P ; Reddy, MV ; Ozoemena, KI ; Balakrishna, RG ; Chowdari, BVR Date: Oct 2015 For the first time, yttrium tin oxide (Y(sub2)Sn(sub2)O(sub7)) compound is prepared at low temperature (400 _C) with cubic pyrochlore structure via molten salt method using KOH as a flux for their electrochemical applications. The final product ... Read more
Spark plasma-sintered Sn-based intermetallic alloys and their Li-storage studies

Author: Nithyadharseni, P ; Reddy, MV ; Nalini, B ; Saravanan, P ; Vinod, VTP ; Cerník, M ; Chowdari, BVR Date: Jun 2016 In the present study, SnSb, SnSb/Fe, SnSb/Co, and SnSb/Ni alloy powders processed by co-precipitation were subjected to spark plasma-sintering (SPS) at 400 °C for 5 min. The compacts were structurally and morphologically characterized by X-ray ... Read more
Studies on bare and Mg-doped LiCoO2 as a cathode material for lithium ion batteries

Author: Reddy, MV ; Wei Jie, T ; Jafta, CJ ; Ozoemena, KI ; Mathe, Mahlanyane K ; Sree Kumaran Nair, A ; Soon Peng, S ; Sobri Idris, M ; Balakrishna, G ; Ezema, FI ; Chowdari, BVR Date: May 2014 In this paper, we report on the preparation of bare and Mg-doped Li(Mg(subx(Co(sub1-x)O(sub2) (x = 0, 0.03, 0.05) phases by a molten salt method and their electrochemical properties. They were prepared at 800 C for 6 h in air. Rietveld refined ... Read more
Synthesis and lithium storage properties of Zn, Co and Mg doped SnO2 Nano materials

Author: Palaniyandy, Nithyadharseni ; Abhilasha, KP ; Petnikota, S ; Anilkumar, MR ; Jose, R ; Ozoemenae, KI ; Vijayaraghavan, R ; Kulkarni, P ; Balakrishna, G ; Chowdari, BVR Date: Sep 2017 In this paper, we show that magnesium and cobalt doped SnO2 (Mg-SnO2 and Co-SnO2) nanostructures have profound influence on the discharge capacity and coulombic efficiency of lithium ion batteries (LIBs) employing pure SnO2 and zinc doped ...
