A nickel-hydrogen battery and a production method for positive pole material of the nickel-hydrogen battery are disclosed, the method comprises the following steps of: 1) production of the positive pole, at first, the surface of spherical nickel hydroxide as positive pole active substance is covered with a gamma-CoOOH covering layer, then the spherical nickel hydroxide whose surface is covered with the gamma-CoOOH is partially oxidized, average chemical valence of the nickel after oxidization is controlled as 2.08-2.20; 2) production of the negative pole, proportion of the capacitance of the negative pole to the capacitance of the positive pole is (1.15-1.25):1; 3) assembly for the negative pole, the positive pole and membrane; 4) formation of the battery, 0.05C-0.2C of current is adopted to activate the battery for 3 to 10 weeks with charge and discharge capacitances during each week being between 30% and 100%, and the current amount of the battery at the time of discharging in the first week is discharged to zero. The positive pole uses the partially-oxidized spherical nickel hydroxide whose surface is covered with the gamma-CoOOH, when the designed capacitance proportion of the positive and negative poles is fixed, the designed capacitance of the negative pole can be reduced correspondingly, powder applying amount of the negative pole is lessened, manufacturing cost of the battery is saved, and the battery is able to maintain the characteristics of long service life and resistance to overcharge.

The invention discloses a powder quantity recognition coffee machine which comprises a bean grinder, a bean box and a brewing system, wherein the brewing system comprises a brewing cup, a brewing plug, a first motor, a rotation number sensor and a controller; a thread is arranged at the peripheral surface of the brewing plug, a screw cap is sleeved on the peripheral surface of the brewing plug, and the brewing plug is in sealed connection with the brewing cup; the first motor is used for driving the screw cap to rotate to drive the brewing plug to move downwards; the rotation number sensor isused for sensing the rotation number n of the screw cap; a datum line is arranged on the brewing cup, and a corresponding screw cap datum turn number n0 is arranged on the controller. When the rotation number n of the screw cap is larger than n0, the powder quantity is too small, so that bean grinding time t is prolonged in the next grinding to improve the powder quantity; when the rotation numbern of the screw cap is smaller than n0, the powder quantity is too large, so that the bean grinding time t in the next grinding can be shortened to reduce the powder quantity. By means of a control process, the coffee powder quantity can be controlled within a standard range, and the phenomenon that the coffee powder quantity is unbalance is avoided.
