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
Electrochemical performance of BaSnO3 anode material for lithium-ion battery prepared by molten salt method

Author: Nithyadharseni, P ; Reddy, MV ; Ozoemena, KI ; Ezema, FI ; Balakrishna, RG Date: Jan 2016 Perovskite-like structure BaSnO(sub3) ceramic oxide has been prepared by low temperature molten salt method using KOH as a flux and Ba(OH)(sub2) and BaCl(sub2) as precursors. The as-prepared compounds were characterized by various techniques ... Read more
Influence of K3Fe(CN)6 on the electrochemical performance of carbon derived from waste tyres by K2CO3 activation

Author: Bello, A ; Momodu, DY ; Madito, MJ ; Makgopa, K ; Rambau, Khavharendwe MA ; Dangbegnon, JK ; Musyoka, Nicholas M ; Manyala, N Date: Apr 2018 Revalorisation of waste tyres to sustainable value added carbons was studied as a possible means of addressing the challenges with rising demand for energy across the globe. Crumble tyres were used for the production of activated carbon (AC) ... Read more
Preparation and electrochemical properties of uniform spherical lithium rich materials xLi2MnO3∙(1-x)LiMn1/3Ni1/3Co1/3O2

Author: Zhou, S ; Liu, G ; Luo, Hongze Date: Sep 2021 The lithium-rich materials xLi2MnO3·（1-x）LiMn1/3Ni1/3Co1/3O2, with uniform spherical shape of 1 µm are successfully prepared via a hydrothermal method combined with calcination process. The content of Li2MnO3 is tuned by adjusting the content ... 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
