The Pb-free solder which Fujitsu developed consists of “stannum zinc and aluminium” and has following features. (1)low melting point: This solder succeeded in realizing melting point of 199? similar to melting point of solder consisting of “stannum and lead” such as 183? although conventional solder consisting of “stannum silver and copper” was high melting point. (2) good wettability: Added aluminum suppresses oxidation of Zn to ensure good wettability.
Main problems in the field of electromobility are the high price and the low capacitance of rechargeable batteries. Important elements of such batteries are aluminium collector foils and their interfaces towards carbon based electrode material. The ohmic resistance of the interface should be minimal. But in air Aluminium generally is oxidized. This thin oxide layer increases the ohmic resistance. Because of this often aluminium collectors are chemically pre-treated to minimise the negative effect of the oxide layer. This chemical step is not only not eco-friendly but also expensive.

“Final energy consumption in the global aluminum industry in 2007 was estimated to be 93 Mtoe. The industry is highly electricity-intensive. Primary aluminum smelters used just over 50 Mtoe of electricity in 2007, equivalent to about 4% of global electricity consumption. In total, the aluminum industry emits 0.4 Gt CO2-equivalent of greenhouse gases, including process emissions and indirect emissions from electricity production, equivalent to just under 1% of total global greenhouse-gas emissions (IEA, 2010).”

L’industrialisation des pays en voie de développement engendre l’augmentation des déchets liquides que sont les huiles de vidange, tout en se heurtant au problème de déficit énergétique. D’autre part, elle s’accompagne d’une forte croissance démographique qui accentue et augmente la quantité de déchets, particulièrement les déchets ménagers solides. Ce qui constitue une réelle menace pour l’environnement et les populations.
