Description

[0001] The present invention relates to an ampoule type reserve battery for enhancing impact resistance,

More particularly, the present invention relates to an ampule-type non-accumulator having increased impact resistance. More specifically, the elastic portion provided on the weight portion for weighting gravitational acceleration absorbs and alleviates an external impact, Type non-accumulating battery which can increase the life span of the battery by reducing the impact resistance of the battery.

The non-accumulator separates the electrode parts made of the positive electrode, the negative electrode and the separator from the electrolyte solution and stores them in an inactive state before use. In use, the electrode part is activated by flowing the electrolyte solution into the inlet part, The problem of the shortened primary battery can be overcome. At this time, the non-storage battery stores the electrolyte solution in the ampoule to isolate the electrolyte from the electrode part, and when applied, it breaks the ampoule by applying an impact exceeding the limit value, so that the electrode part is activated by the electrochemical reaction by the electrolyte solution.

The non-accumulating battery has an advantage of having a long lifetime by suppressing natural discharge, and its application field and demand are gradually increasing. However, in the conventional non-accumulating battery, due to a user's mistake, The ampoule is easily broken due to the impact, and thus the life span is shortened due to natural discharge during use.

The present invention researched a non-storage battery including a protection case provided inside a case and provided with a glass-made partition wall at the bottom thereof, and a support portion pressed against the inside of the protection case to be pressed into the protection case, 10-1306275 (name of the invention: non-accumulating battery with improved impact resistance and durability), and the non-accumulating battery prevents the sidewall of the protection case from being deformed when an impact occurs from the side of the case, The breakage of the partition due to the external impact can be effectively prevented and the impact resistance and the durability can be improved.

However, since the non-accumulator is stored not in the ampoule but in a state of being separated from the electrode portion by the partition wall made of a thin plate made of glass, the non-accumulator is disadvantageous in that the ampoule is easily damaged in the up- , Thereby shortening the lifetime of the battery.
