An adaptive interposer is provided to be operably disposable between first and second solder materials of first and second electronic devices, respectively. The adaptive interposer includes a plate element formed to define cavities and third solder material disposable in the cavities to be electrically communicative with the first and second solder materials. The third solder material is more compliant and has a higher melting temperature than at least the second solder materials.

A valve regulated lead-acid battery includes a positive electrode current collector which is a punched current collector obtained by punching a rolled sheet of lead alloy and in which the average interlayer distance in a layered current collector structure at a cross-section parallel to the rolling direction and along the thickness direction of the current collector is not less than 25 µm and not more than 180 µm.
摘要:
A lead-acid battery grid made from a lead-based alloy containing tin, calcium, bismuth and copper and characterized by enhanced mechanical properties, corrosion resistance, less battery gassing, lower sulfation and water loss, and no post-casting treatment requirements for age hardening. In one embodiment, the battery grids are formed from a lead-based alloy including about 2.0% tin, about 0.0125% copper, about 0.065% calcium, and about 0.032% bismuth. Preferably, the battery grid is free of silver beyond trace levels in the alloy.
