Why are alkaline batteries not recommended?
Compared to other batteries, alkaline batteries have some disadvantages. For example, compared with a lithium ion battery, an alkaline battery is bulkier and heavier. Note that li-ion batteries have higher energy density. Another disadvantage of alkaline battery is high internal resistance.
Why are alkaline batteries better than acid batteries?
Alkaline batteries pack in more energy than other types. For example, an alkaline battery has double the energy density of a zinc-carbon battery. As a result, alkaline cells and batteries can produce the same energy as other batteries while lasting longer. Personal and environmental safety.
Why do alkaline batteries last longer than lead acid?
Alkaline batteries have a high capacity, higher than nickel metal hydride rechargeable cells so they last longer without running flat. Also, alkaline batteries have a low self-discharge rate meaning that even if they aren't supplying current, they don't lose much of their energy.
What is alkaline battery used for?
Alkaline batteries are used in many household items such as MP3 players, CD players, digital cameras, toys, flashlights, and radios.
What is an alkaline battery?
An alkaline battery (IEC code: L) is a type of primary battery which derives its energy from the reaction between zinc metal and manganese dioxide . Compared with zinc–carbon batteries of the Leclanché cell or zinc chloride types, alkaline batteries have a higher energy density and longer shelf life, yet provide the same voltage.
How much more capacity does an alkaline battery have than an acidic battery?
An alkaline cell can provide between three and five times the capacity of an acidic cell.
What is the negative electrode of an alkaline battery?
In an alkaline battery, the negative electrode is zinc and the positive electrode is manganese dioxide (MnO 2 ). The alkaline electrolyte of potassium hydroxide is not part of the reaction, only the zinc and MnO 2 are consumed during discharge. The alkaline electrolyte of potassium hydroxide remains, as there are equal amounts ...
How much of the US battery is alkaline?
Alkaline batteries account for 80% of manufactured batteries in the US and over 10 billion individual units produced worldwide. In Japan, alkaline batteries account for 46% of all primary battery sales. In Switzerland, alkaline batteries account for 68%, in the UK 60% and in the EU 47% of all battery sales including secondary types. Alkaline batteries contain zinc (Zn) and manganese dioxide (MnO 2) (Health codes 1), which is a cumulative neurotoxin and can be toxic in higher concentrations. However, compared to other battery types, the toxicity of alkaline batteries is moderate.
Why is zinc used in batteries?
Its purpose was to control electrolytic action at impurity sites, which would reduce shelf life and promote leakage. With reductions in mercury content being mandated by various legislatures, it became necessary to greatly improve the purity and consistency of the zinc.
How much current can an alkaline battery deliver?
A rule of thumb is that an AA alkaline battery can deliver 700 mA without any significant heating. Larger cells, such as C and D cells, can deliver more current. Applications requiring currents of several amperes, such as powerful flashlights and portable stereos, will require D-sized cells to handle the increased load.
When were nickel and iron batteries invented?
Thomas Edison's nickel–iron batteries manufactured under the " Exide " brand, originally developed in 1901 by Thomas Edison used a potassium hydroxide electrolyte.

Overview
History
Batteries with alkaline (rather than acid) electrolyte were first developed by Waldemar Jungner in 1899, and, working independently, Thomas Edison in 1901. The modern alkaline dry battery, using the zinc/manganese dioxide chemistry, was invented by the Canadian engineer Lewis Urry in the 1950s in Canada before he started working for Union Carbide's Eveready Battery division in Cleveland, OH, …
Chemistry
In an alkaline battery, the negative electrode is zinc and the positive electrode is manganese dioxide (MnO2). The alkaline electrolyte of potassium hydroxide is not consumed during the reaction, only the zinc and MnO2 are consumed during discharge. The alkaline electrolyte of potassium hydroxide remains, as there are equal amounts of OH consumed and produced.
The half-reactions are:
Capacity
The capacity of an alkaline battery is greater than an equal size Leclanché cell or zinc chloride cell because the manganese dioxide is purer and denser, and less space is taken up by internal components such as electrodes. An alkaline cell can provide between three and five times the capacity of an acidic cell.
The capacity of an alkaline battery is strongly dependent on the load. An AA-sized alkaline batter…
Voltage
The nominal voltage of a fresh alkaline cell as established by manufacturer standards is 1.5 V. The actual zero-load voltage of a new alkaline battery ranges from 1.50 to 1.65 V, depending on the purity of the manganese dioxide used and the contents of zinc oxide in the electrolyte. The voltage delivered to a load decreases as the current drawn increases and as the cell discharges. A cell is considered fully discharged when the voltage drops to about 1.0 V. Cells connected in seri…
Current
The amount of electrical current an alkaline battery can deliver is roughly proportional to its physical size. This is a result of decreasing internal resistance as the internal surface area of the cell increases. A rule of thumb is that an AA alkaline battery can deliver 700 mA without any significant heating. Larger cells, such as C and D cells, can deliver more current. Applications requiring currents of several amperes such as powerful portable audio equipment require D-size…
