Abstract: An electrode for an energy storage device including a Zn layer or Zn alloy layer, a Ni layer, and a Sn layer or Sn alloy layer formed by plating on a connecting terminal part of a positive electrode composed of Al so that the resistance value at the contacting point is reduced and the voltage of the energy storage device can be effectively supplied without any drop. Accordingly, this electrode can be soldered to a Cu negative electrode, which is composed of metal that is different species from Al, through a Sn layer or a Sn alloy layer so that jointing strength of the Al positive electrode and the Cu negative electrode can be enhanced. The contacting area is increased in comparison with the conventional jointing by spot-welding or conventional fastening by a bolt so that the resistance value at the contacting point is reduced.

Abstract: Zn layer 21 or Zn alloy layer, Ni layer 22, and Sn layer 23 or Sn alloy layer are formed on a connecting terminal part 10a of a positive electrode composed of Al by plating. Accordingly, this can solder Cu negative electrode, which is composed of metal that is different species from Al, through Sn layer 23 or Sn alloy layer so that jointing strength of the Al positive electrode and the Cu negative electrode can be enhanced. Further, since the contacting area is increased in comparison with the conventional jointing by the spot-welding or the conventional fastening by a bolt so that the resistance value at the contacting point is reduced, the voltage drop of the energy storage device by contact resistance can be reduced.

Zn layer 21 or Zn alloy layer, Ni layer 22, and Sn layer 23 or Sn alloy layer are formed on a connecting terminal part 10a of a positive electrode composed of Al by plating. Accordingly, this can solder Cu negative electrode, which is composed of metal that is different species from Al, through Sn layer 23 or Sn alloy layer so that jointing strength of the Al positive electrode and the Cu negative electrode can be enhanced.

Abstract: A pressure-sensitive adhesive for use in temporarily securing electronic devices, particularly surface-mounting devices onto a printed circuit board in position during soldering, thereby preventing the devices from dropping from the board. The pressure-sensitive adhesive consists essentially of a resinous material having a dynamic modulus of elasticity in the range of from 10.sup.4 to 10.sup.9 dyne/cm.sup.2 as measured at the soldering temperature of the electronic devices with a frequency of applied vibrations of 10 Hz. Preferably, the resinous material has a dynamic modulus of elasticity in the range of from 10.sup.4 to 10.sup.7 dyne/cm.sup.2 and a value for tan .delta. of greater than 0.2 as measured under the above conditions. In this case, the pressure-sensitive adhesive exhibits a self-aligning effect whereby electronic devices mounted out of position on the board are forced to move toward the proper positions by the action of the surface tension of a molten solder.
