What does a 1.5v battery look like?

A 1.5V battery typically looks cylindrical with a positive and negative terminal, resembling common household batteries like AA or AAA cells.

Cell Voltage

The voltage of electric batteries stems from the potential difference between the materials constituting the positive and negative electrodes in the electrochemical reaction.

Each lithium-ion cell typically generates a voltage of approximately 3.6 volts, presenting several advantages. With its higher voltage compared to standard nickel-cadmium, nickel-metal hydride, and even alkaline cells (around 1.5 volts), as well as lead-acid cells (around 2 volts per cell), fewer lithium-ion cells are needed in various battery applications.

Batteries with voltages exceeding 1.5 volts are commonly comprised of cells connected in series within a single casing. For instance, a 9-volt battery integrates six cells linked in series (6 × 1.5 Volt = 9 Volt).

To determine a battery’s voltage, nominal voltages are marked, representing the average voltage output when fully charged, although this may differ from the open circuit voltage.

External factors like low temperature can decrease the anticipated voltage output, while higher temperatures favor electrochemical reactions, leading to increased voltage.

To prevent batteries from discharging below a certain level that could damage them, a voltage limit known as the cut-off voltage is established.

Cell Voltage

1.5V (DC)

A typical open circuit voltage for non-rechargeable alkaline batteries like AAA, AA, and C cells.

3V (DC)

Lithium-based primary cells, which feature metallic lithium as an anode, typically exhibit a voltage of 3V, as seen in most lithium-metal cells (e.g., button cells).

3.8V (DC)

Nearly all lithium-ion batteries operate at 3.8 volts. For current to flow from the charger to the battery, a potential difference is necessary. Consequently, battery chargers or USBs for nearly all smartphones supply a voltage of 5V.

Automobile batteries typically operate at 12 volts (DC), which is composed of six 2V lead cells. Each battery functions by maintaining the separation between the cathode and anode to prevent a reaction until the circuit is closed, allowing electrons to flow.

In essence, batteries directly convert chemical energy into electrical energy. This chemical energy is stored in high-energy metals like Zn or Li, which lack stabilization via d-electron bonding, unlike transition metals.

Irrespective of battery type, all batteries leverage the oxidation-reduction reaction principle. Spontaneous redox reactions occur in an electrochemical cell with two electrodes separated by an electrolyte—an ionic conductive and electrically insulated substance.

This reaction involves a change in oxidation states of the atoms, with electrons transferred from one element to another. The donor element, the anode, undergoes oxidation (loses electrons), while the recipient element, the cathode, undergoes reduction (gains electrons).

For instance, in an alkaline battery, the negative electrode comprises zinc (Zn), while the positive electrode consists of high-density manganese dioxide (MnO2). The alkaline electrolyte, typically potassium hydroxide (KOH), remains unaltered during the reaction, with only zinc and MnO2 being consumed during discharge.

Chemistry of Alkaline Batteries

Half Reaction

Zn(s) + 2OH−(aq) → ZnO(s) + H2O(l) + 2e− [Eoxidation° = +1.28 V]

2MnO2(s) + H2O(l) + 2e− → Mn2O3(s) + 2OH−(aq) [Ereduction° = +0.15 V]

Overall reaction

Zn(s) + 2MnO2(s) ⇌ ZnO(s) + Mn2O3(s) [e° = +1.43 V]

In practical application, the electrons generated during this reaction power devices when the circuit is closed.

Why are alkaline batteries (AAA or AA) made to be 1.5V while rechargeables are 1.2V?

In essence, batteries harness stored chemical energy to generate electrical energy through an electrochemical process, thereby providing electromotive force to facilitate current flow in electric and electronic circuits.

Primary (single-use or alkaline) batteries utilize cells with a 1.5V open circuit voltage when fresh, whereas secondary (rechargeable) batteries employ cells from NiMH or NiCd, boasting a 1.2V open circuit voltage.

In practical terms, alkaline batteries and rechargeable batteries are interchangeable within sets, distinguished primarily by their voltage characteristics dictated by their respective chemistries. Primary cells exhibit a gradual voltage decline with use, starting at 1.5 volts, descending to 1.2 volts, and ultimately dropping to 1.0 volts where device operation ceases.

Secondary cells, on the other hand, maintain a more consistent voltage, hovering around 1.2 volts until depleted, after which they rapidly plummet below 1.0 volts.

Given that electronic devices are typically designed to operate within a voltage range of 1.0 to 1.5 volts, alkaline and rechargeable batteries demonstrate similar performance. However, it’s generally acknowledged that secondary 1.2V cells outperform alkalines due to their lower output impedance and more uniform voltage delivery throughout the charge cycle.
