“…Therefore, reducing the weight of the noncapacity contributing components, such as substrate, can improve the specific energy of the batteries [15,16]. The weights of the tested substrates in this work are listed in Table 1.…”

A lightweight and inexpensive stainless steel mesh has been investigated as an electrode substrate material for Li/polypyrrole rechargeable battery. The effects of substrate materials on surface morphology of films, charge-discharge capacity and coulombic efficiency are discussed in detail. The results show that the capacity of the cell with stainless steel mesh is about 10% lower than the cell using platinum mesh, but it is much lighter and cheaper than that of platinum mesh, therefore, it is a promising substrate material for Li/polymer batteries.

“…1 Although lead-acid batteries are considered a mature technology, significant research and development efforts are currently underway to enhance their specific energy, [2][3][4][5][6][7][8][9][10][11][12][13][14] which currently remains restricted to only about 30 Wh/kg owing to the high mass-density of lead.…”

A novel room-temperature route to corrosion protect lead-coated plastic grids with an organic metal, namely, polyaniline, for producing commercial-grade high specific-energy 12 V/45 Ah lead-acid batteries is reported. The specific energy of these leadacid batteries is found to be ca. 45 Wh/kg as against about 30 Wh/kg for conventional lead-acid batteries. It is believed that the study reported here will open up a new realm of possibilities for lead-acid battery development, and will contribute directly towards lowering the cost of both battery materials and manufacturing.

“…In the literature are reports [3][4][5][6][7][8][9][10][11][12][13][14][15] of several efforts expended to enhance the energy density of lead/acid batteries primarily by employing lightweight grid materials. Hammar and Harvey 3 reported a lead/acid battery in which the grids comprise a substrate made of a polymer, such as polyvinylchloride, laminated with a thin lead/lead alloy foil.…”

“…Other efforts to develop high energy density lead/acid battery are directed toward more advanced research designs. [10][11][12][13][14][15] From the foregoing, it is evident that to realize low-cost, high energy-density lead/acid batteries, it is desirable to develop a process, which allows the corrosion-resistant oxide coating on lead/lead alloy layer to be formed on battery grids constructed from a lightweight and inexpensive material, usually having a low melting point. Such grids may then be used to fabricate lead/acid batteries, which would have higher energy densities and a longer lifetime than conventional lead/acid batteries.…”

Lightweight plastic grids for lead/acid battery plates have been prepared from acrylonitrile butadiene styrene copolymer. The grids have been coated with a conductive and corrosion-resistant tin oxide layer by a novel rapid thermally activated chemical reaction process. X-ray powder diffraction and X-ray photoelectron spectroscopy show the coated tin oxide film to be SnO 2 -like. The grids are about 75% lighter than conventional lead/acid battery grids. A 6 V/1 Ah lead/acid battery has been assembled and characterized employing positive and negative plates made from these grids. The energy density of such a lead/acid battery is believed to be more than 50 Wh/kg.
