The utility model aims to solve the problems of the prior art, and aims to provide a lithium manganese button cell of new size, which has the advantages of larger discharge capacity and load capacity under the condition of the same diameter, improved system stability inside the cell due to the change of cell height, and prolonged storage life of the cell.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a lithium manganese button cell of full new dimension, includes the positive pole shell, and the seal groove has been seted up to the upper surface of positive pole shell, and the inner wall fixedly connected with sealing washer of seal groove, the battery chamber has been seted up to the inside of positive pole shell, and the upper surface fixedly connected with negative pole lid of positive pole shell.
Further, the diameter of the positive electrode can is 12mm, and the height from the bottom surface of the positive electrode can to the upper surface of the negative electrode cover is 2.5 mm;
through the technical scheme, the battery has larger discharge capacity and load capacity under the condition of the same diameter, and the system stability in the battery is also improved due to the change of the height of the battery, so that the storage life of the battery is prolonged.
Furthermore, a positive plate taking manganese dioxide as a main component, a diaphragm, a negative electrode formed by a lithium strip and electrolyte are arranged in the battery cavity;
through the technical scheme, the electrifying effect of the battery is improved, and the service life is prolonged.
Furthermore, circular salient points are arranged on the upper surface of the negative electrode cover and are uniformly distributed on the surface of the negative electrode cover;
through the technical scheme, the salient points on the surface of the negative electrode cover are achieved, and the contact between the battery and an electric appliance is improved.
To sum up, the utility model discloses following beneficial effect has:
the diameter through setting up positive pole shell is 12mm, the height that the bottom surface of positive pole shell was covered to the negative pole is 2.5mm, the upper surface of negative pole lid is provided with circular bump, circular bump all with the distribution on the surface of negative pole lid, thereby reached under the condition of the same diameter, possess bigger discharge capacity and load capacity, the change of battery height has also improved the inside system stability of battery, thereby the storage life of battery has been increased, and the bump on negative pole lid surface, the contact nature of battery and power consumption utensil has been increased.
