Abstract: A structure of lithium-ion battery module comprises a battery case, containing one or more flexible packaging polymer lithium-ion battery cells, at of which top a connecting conductor is arranged to connect them in series and/or parallel to form a battery pack, positive and negative poles of the battery pack are mounted on the connecting conductor. The structure further comprises a battery cover plate welded on the open end of the battery case to package the battery pack into the battery case, and the positive and negative pole terminals of the battery module are arranged on the battery cover plate and welded to the positive and negative poles. The plate is provided with one or more through hole, through which the air in the battery case is evacuated and the inert gas is injected, after that a steel ball is clamped into each through hole to seal the battery case.

Abstract: A gastight, sealed metal oxide/metal hydride storage battery, in particular, a nickel/metal hydride button cell, includes an auxiliary electrode with an active material composed of the same hydrogen storage alloy as that of the negative electrode with which the auxiliary electrode is electrically associated. As a result, the auxiliary electrode can maintain both oxygen consumption as well as hydrogen consumption (in the event of overcharging or polarity reversal of the cell). High gas consumption rates in the event of overcharging and polarity reversal are achieved with a strongly hydrophobic adjustment of the auxiliary electrode and a relatively weakly hydrophobic or hydrophilic adjustment of the negative electrode (by means of hydrophobic or hydrophilic binder additions, respectively), and by adding a highly conductive metal powder (Cu or Ni) to the mass of the negative electrode. Also achieved is a good discharge capacity, even at high currents of up to 2 CA.
