Negative Electrode
The electrode that has a lower electrical potential
than the positive electrode to which electrical
current flows from the external circuit during the
discharge of a storage battery.
Nickel Oxyhydroxide
Expressed in chemical notation as NiOOH, this
indicates that the positive electrode material of
the Ni-Cd battery is in a charged state. When in
the discharged state, the positive electrode
material becomes nickel hydroxide, or Ni(OH)2.
Nominal Voltage
The voltage used to indicate the battery voltage.
Generally a value slightly lower than the
electromotive force is used. For example, the
nominal voltage of rechargeable Ni-Cd batteries is
1.2 V per cell.
Open Circuit Voltage
The voltage of a battery when that battery is
electrically cut-off from the external circuit.
Overcharge Current
Charge after the fully charged state has been
reached. In a rechargeable battery which requires
water replenishment, the electrolysis of the water
causes a sharp decrease in the amount of
electrolyte. Generally, the overcharge of a
rechargeable battery will shorten the battery’s
cycle life.
Pasted Type Electrode Plate
An electrode plate made by applying as the active
material a cadmium compound in a paste form
onto a nickel-plated steel porous plate. Used as
the negative electrode.
Positive Electrode
The positive electrode that has a higher electrical
potential than the negative electrode from which
electrical current flows to the external circuit
during the discharge of a rechargeable battery.
Rapid Charge
Charge quickly using a large current.
Rated Capacity
The standard value for the amount of electricity
which can be obtained from the battery in a fully
charged state at the specified temperature,
discharge current, and cut-oft discharge voltage.
Measured in units of ampere-hours (Ah).Note that
CN is used as a symbol to express the rated
capacity at a rate of N hours.

Reverse Charge
Charge with the polarities reversed.
If the polarities are reversed, all of the electrical
energy will be used to generate gas.
Functions to release the gas when the internal
pressure exceeds a predetermined level. In
addition to preventing the absorption of external
air into the rechargeable battery, this vent also
prevents the rupture of the rechargeable
battery that would result from the increase in the
internal pressure caused by the generation of
gas during charge or at other times.
Self-discharge
A decrease in the capacity of a rechargeable
battery without any discharge of current to the
external circuit.
Separator
A porous or micro-porous thin plate, cloth, bar,
or frame which is inserted as a spacer between
the positive and negative electrode plates for
the purpose of preventing short-circuits. The
separator must be non-oxidizing, resistant to
chemicals, and be an electrical insulator, and it
must not obstruct in any way the ionic
conduction or diffusion of the electrolyte.
The separator also functions to retain the
electrolyte.
Sintered Electrode Plate
An electrode plate in which the active material is
impregnated into a porous thin-plate substrate
prepared by sintering nickel powder to a porous
plate made of nickel or nickel-plated steel. Used
as the positive electrode plate.
Sintered Substrate (Plaque)
The substrate for the active material, made by
sintering nickel powder to a porous plate.
Trickle Use
A method of use in which the battery is cut-off
from the load and constantly charged at a very
small current in order to replenish the self-
discharge. Mostly used for emergency power
supply applications, such as in the event of an
interruption in the normal power supply.
