have the function of storing electricity and discharging when
necessary. The electricity generated by the discharge is "direct
current", and the electric devices that operate using dry batteries are
made to operate with direct current.
the structure of the dry cell, the cylinder of zinc is a negative pole, the
carbon rod in the center and manganese oxide are the positive electrode, and
electrons are moved from the minus pole to the plus pole in the reaction of the
electrolyte charged inside. Because naturally it does not react with zinc
cylinder and carbon rod alone, electrolyte is filled as a material for
a lead storage battery, the electrolyte cannot be put into a watch as a liquid,
and it cannot be used as a remote control of a television. The electrolyte
filled in the dry battery is soaked in the non-woven fabric to be solidified,
and storage, transportation and installation are very simple.
the batteries and looking at the electrolyte in them, you can see that powdered
solids are contained. Using "dry electrolyte" is derived from
Capacity of dry batteries
standard of dry cell batteries, single AAA, single AA ... ... standardizes the
capacity and size of batteries. For large-capacity electric appliances, it
is possible to operate for a long time efficiently by using single
batteries. In the case of miniaturized electric appliances, the operation
time is shortened, but by using AAA or AAA batteries, the main body of the
device can be made small.
comparison with Panasonic's alkaline dry batteries, in the case of a single
battery the end voltage will be 150 hours after the current of 100 mA, but in
the case of the AA battery the end voltage will be about 20 hours with a
current of 100 mA. Smaller numbers withstand operation for a long time and
are resistant to instantaneous large currents.
an aside, the manganese dry battery classifies black as super high performance,
red as high performance, black as long as it operates on the same manganese dry
battery for a long time · performance of instantaneous high current flowing
becomes high. When using a new battery, red and black are different in
performance and should not be mixed.
batteries are batteries that can supply a voltage of 1.5 V per piece, and are
suitable for devices that use minute electric power for a long time, such as
television remote control and watch. Conventional unit price is about half
the price of alkaline batteries, but now the unit price of alkaline dry
batteries has been declining considerably, so no big difference has been felt.
dry batteries are suitable as electric appliances that operate for a long time
with small electric power such as a wall clock and a clock, or dry batteries
that are used for instantaneous cases (such as for igniting a gas stove) even
when large electric power is required. It is said to be inexpensive in dry
manganese dry battery has a carbon rod called a current collector at the
center, and it cannot be charged with primary battery using manganese dioxide
as a positive electrode active material and zinc as a negative electrode active
material and using zinc chloride or ammonium chloride as an electrolytic
solution. The positive electrode and the negative electrode are separated
from each other by a separator. The carbon rod, the positive electrode,
and the negative electrode are covered with an insulating tube, and a metal
jacket is applied to the exterior.
the property of zinc chloride aqueous solution which is the electrolyte of
manganese dry battery is almost neutral, leakage occurs by any chance and even
if it comes in contact with the human body, the damage can be kept
small. Even if liquid leakage occurs inside the electric device, the
powder blows but it is relatively safe without corroding the metal.
nominal voltage is 1.5 V, and grades are classified into "popular
products", "high performance items", and "ultra-high
performance items" by discharge characteristics and capacity.
