A mercury-free lead-free button battery includes a negative cap, a cathode material, a gasket ring, a positive can, an anode material, and a diaphragm. The positive can and the negative cap are combined. The gasket ring is clamped between the positive can and the negative cap for separating the positive can from the negative cap. The cathode material is arranged on the bottom of the positive can. The diaphragm is arranged on the cathode material. The anode material is arranged between the negative cap and the diaphragm. A partition unit is arranged between the negative cap and the anode material for separating the anode material from the negative cap and conductively connecting the anode material and the negative cap. The partition unit ensures disconnection between the anode material and the negative cap and therefore safety of the battery by preventing expansion, weeping and even that would otherwise happen. |

1. A mercury-free lead-free button battery, comprising a negative cap, a cathode material, a gasket ring, a positive can, an anode material that is conductively connected to the negative cap and a diaphragm that separates the cathode material from the anode material; the positive can and the negative cap being combined in a buckling manner; the gasket ring being clamped between the positive can and the negative cap, so as to separate the positive can from the negative cap; the cathode material being deposited on an inner bottom of the positive can, the diaphragm being arranged on the cathode material; and the anode material being installed between the negative cap and the diaphragm; the mercury-free lead-free button battery being characterized in that a partition unit is arranged between the negative cap and the anode material for separating the anode material from the negative cap and conductively connecting the anode material and the negative cap, and the partition unit comprises a partition membrane and a current collector, the partition membrane covering an inner surface of the negative cap and reaching a bottom, a top, or a site between the bottom and the top of a rim portion of the negative cap, the partition membrane separating the anode material from the negative cap, and the current collector conductively connecting between the anode material and the negative cap. |
