Durable mechanical and electronic contact is achieved between the support frame of a battery electrode and its active material A, whose electro-chemical capacity is utilizable to a very high degree, by providing the base material M.sub.1 of the support frame, which is not itself capable of being alloyed with A, with a cover layer of a metal M.sub.2 that is capable of being alloyed with M.sub.1, as well as being capable of being alloyed with A. This results in an alloy region M.sub.1.M.sub.2, within which the alloying reaction with A comes to a halt. The contact region corresponds to the scheme M.sub.1 /M.sub.1.M.sub.2.A/A. Alternatively, the active material can itself be an alloy of M.sub.2 and A, in accordance with M.sub.1 /M.sub.1.M.sub.2.A/M.sub.2.A.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
