“…Alternative slightly lower capacity materials that can still be processed in 3D were also investigated. We have previously reported on the Cu 6 Sn 5 anode material and the achievement of a steady capacity after the early cycles (14). The capacity of the Cu 6 Sn 5 nanowire anodes stabilized around 200 mAhg -1 .…”

Energy provision and storage are significant and critical issues for wireless sensor network (WSN) applications. Hybrid energy devices incorporating energy harvesting and storage requires the development of enhanced energy storage materials and architectures. A decreased footprint with the same energy capability is desirable to maximise the energy density and enable long-life wireless sensors. Methods to structure active and support battery materials enhance the device characteristics offering mechanical and electrical support. The results below are for materials that can be processed in 3D or 1D to decrease the footprint of the energy storage element. The effect of the support material is also shown to be significant and directly relevant for high aspect ratio nanostructure where the lithium active materials experience volume changes during charge and discharge.

“…The capacity of the Cu 6 Sn 5 nanowire anodes stabilized around 200 mAhg -1 . Higher capacity materials are desirable and a Sn rich Cu alloy was investigated by deposition in an alumina template as described earlier (14). The composition achieved was Cu 3 Sn 5 .…”

“…Vertical arrays of one-dimensionalNanotubes of the polycrystalline SnO 2 have been synthesized through an infiltration technique using SnO 2 nanoparticles as starting building units and AAO as template. [55] A reversible capacity of 525 mAh/g was retained after 80 cycles. Thus there are inexpensive high energetic electrodes available for new battery materials which can be experimented further for future battery applications.…”

Though battery chemistry and technology had been developed for over a hundred years back, increase in demand for storage energy, in the computer accessories, cell phones, automobile industries for future battery car and uninterrupted power supply, has made, the development of existing and new battery, as an emerging areas of research. With innovation of high energetic inexpensive Nano structure materials, a more energy efficient battery with lower cost can be competitive with the present primary and rechargeable batteries. Materials electrochemistry of electrode materials, their synthesis and testing have been explained in the present paper to find new high efficient battery materials. The paper discusses fundamental of electrochemistry in finding true cell potential, overvoltages, current, specific energy of various combinations of anode-cathode system. It also describes of finding the performance of new electrode materials by various experiments viz. i. Cyclic Voltammetry ii. Chronoamperometry iii. Potentiodynamic Polarization iv. Electrochemical Impedance Spectroscopy (EIS). Research works of different battery materials scientists are discussed for the development of existing battery materials and new nano materials for high energetic electrodes. Problems and prospects of a few promising future batteries are explained.

“…[129] 1D nanowires or nanotubes of metals, semiconductors or oxides provide a route to enhanced battery materials as they suppress strains, minimise pulverisation and provide good electronic contact and conduction pathways when grown directly on the current collector. Cu 6 Sn 5 nanowires [130] with a measured height of 5 μm and diameter of 250 nm or an aspect ratio of 20 have been studied by cyclic voltammetry, figures 8 and 9. The first charge and discharge capacity of the nanowires was 325 mAh/g.…”
