Alkaline batteries typically use a zinc anode and a manganese dioxide cathode with a potassium hydroxide electrolyte. This combination provides higher energy density and longer shelf life than older zinccarbon cells. The alkaline chemistry is widely used in household batteries. More info.
What is the nominal voltage of a standard AA alkaline battery?
1.2 volts
1.5 volts
9 volts
3 volts
A standard AA alkaline cell delivers a nominal voltage of 1.5 V. Rechargeable NiMH AA cells typically provide about 1.2 V due to their different chemistry. Specialized lithium AA cells can offer 1.7 V or more. More info.
What does the term 'mAh' measure in battery specifications?
Voltage
Current
Capacity
Resistance
mAh stands for milliampere-hour and indicates the charge a battery can deliver over one hour. It is a measure of capacity, not voltage or current alone. Higher mAh values generally mean longer run times. More info.
Which term describes the energy stored per unit mass of a battery?
Energy density
Specific energy
Power density
Charge efficiency
Specific energy is the energy stored per unit mass (Wh/kg) of a battery. Energy density, by contrast, is energy per unit volume (Wh/L). Power density measures how fast energy can be delivered per mass. More info.
What is the main thermal hazard associated with lithium-ion batteries?
Thermal runaway
Sulfation
Memory effect
Dendrite formation
Thermal runaway is an uncontrolled rise in temperature that can cause fire or explosion in lithium-ion cells. It occurs when internal heat-generating reactions accelerate. Proper management systems and cooling are critical to prevent it. More info.
On average, after how many full charge-discharge cycles does a typical lithium-ion smartphone batterys capacity drop below 80%?
50 cycles
100 cycles
500 cycles
1000 cycles
Most smartphone lithium-ion batteries retain about 80% of their initial capacity after around 500 full charge cycles. Cycle life can vary with depth of discharge, temperature, and charging patterns. Manufacturers often specify this rating in their datasheets. More info.
Which material serves as the positive electrode in a lead-acid battery?
Lead (Pb)
Lead dioxide (PbO2)
Nickel hydroxide
Manganese dioxide
A lead-acid batterys positive plate is made of lead dioxide (PbO2). The negative plate is spongy lead (Pb). During discharge, both plates convert to lead sulfate. This chemistry is favored for high surge currents. More info.
What does the 'C-rate' of a battery indicate?
Chemical composition
Charge and discharge current relative to capacity
Temperature coefficient
Internal resistance
C-rate is the rate at which a battery is charged or discharged relative to its capacity. A 1C rate means charging or discharging in one hour. Higher C-rates denote faster processes but may reduce efficiency. More info.
Which process is commonly used to extract valuable metals from spent battery materials?
Crystallization
Distillation
Pyrometallurgy
Electroplating
Pyrometallurgy uses high-temperature smelting to recover metals like cobalt, nickel, and lithium from spent batteries. It is widely employed in large-scale recycling. Hydrometallurgy is another method but less common for bulk processing. More info.
In battery management systems, what does 'SOC' stand for?
System operational check
State of charge
Standard output current
Safety overcurrent cutoff
SOC means state of charge, representing the remaining battery capacity as a percentage of full charge. Accurate SOC estimation ensures reliable operation and avoids over-discharge. It is critical in electric vehicles and storage systems. More info.
The 'memory effect' is a phenomenon most associated with which battery chemistry?
Lithium-ion
Lead-acid
Nickel-cadmium
Alkaline
Memory effect refers to reduced capacity in NiCd batteries when they are repeatedly charged after shallow discharges. Over time, the battery 'remembers' a lower capacity limit. It is largely absent in NiMH and lithium-ion technologies. More info.
What is the electrolyte composition used in traditional lead-acid batteries?
Potassium hydroxide solution
Sulfuric acid solution
Sodium chloride solution
Hydrochloric acid solution
Lead-acid batteries use sulfuric acid diluted with water as the electrolyte. The acid participates directly in the electrochemical reactions during charge and discharge. Proper acid concentration is essential for performance and longevity. More info.
What term describes the gradual loss of charge in a battery when not in use?
Self-discharge
Internal resistance
Cycle life
Voltage sag
Self-discharge is the natural process where batteries lose their stored energy over time even when idle. All battery chemistries exhibit this to varying degrees, with rates accelerating at higher temperatures. It affects long-term storage viability. More info.
Peukerts law relates battery capacity to which factor?
Ambient temperature
Discharge current
State of health
Charging voltage
Peukerts law quantifies how the effective capacity of a lead-acid battery decreases as the discharge current increases. It shows that higher currents yield less usable capacity than lower currents. The relationship is defined by the Peukert exponent. More info.
What is the nominal voltage of a single lithium iron phosphate (LiFePO4) cell?
2.4 volts
3.2 volts
3.6 volts
4.2 volts
LiFePO4 cells have a nominal voltage of about 3.2 V due to their phosphate-based cathode chemistry. They are valued for thermal stability, safety, and long cycle life compared to other lithium chemistries. Their maximum charge voltage is typically around 3.63.65 V. More info.

Cheat Sheet
Volta's Pile - Origin of the Battery -
Alessandro Volta's voltaic pile, invented in 1800, consisted of alternating zinc and copper discs separated by brine-soaked cloth, delivering about 1.1 V per cell (American Chemical Society). A useful mnemonic is "Zinc gives, Copper takes" to remember electron flow from Zn to Cu. This fundamental design often appears in the national battery day quiz and in battery trivia quiz questions about battery origins.
Standard Potentials and the Nernst Equation -
Standard reduction potentials (EĀ°) allow you to calculate cell voltages using EĀ°cell = EĀ°cathode ā EĀ°anode, a method outlined by IUPAC. The Nernst equation, E = EĀ° - (RT/nF) ln Q, adjusts voltage for temperature, concentration, and ion activities, which is essential for a robust battery knowledge test. Questions on how changing conditions influence voltage frequently appear in advanced battery quizzes.
Battery Chemistries: Primary vs. Secondary -
Batteries are classified as primary (non-rechargeable) or secondary (rechargeable); alkaline cells use zinc and manganese dioxide, while lead-acid, NiMH, and Li-ion are popular rechargeable types (U.S. Department of Energy). Remember "Lead is heavy but rechargeable" versus "Li-ion is light with high energy density" to distinguish common chemistries. This comparison often shows up in the history of batteries quiz when contrasting Edison's alkaline design with modern developments.
Lithium-Ion Dynamics and Energy Density -
Lithium-ion batteries operate via lithium intercalation in graphite anodes and transition-metal oxide cathodes, achieving energy densities up to 250 Wh/kg, compared to 25 - 35 Wh/kg for lead-acid (Journal of Power Sources). Key half-reactions include LiCā ā Cā + Liāŗ + eā» at the anode and LiāāāCoOā + xLiāŗ + xeā» ā LiCoOā at the cathode. Understanding how composition affects capacity and voltage is crucial for acing a battery quiz on cell chemistry.
Performance Metrics: C-Rate, Cycle Life, and Self-Discharge -
Important performance metrics include C-rate (charge/discharge speed), cycle life (cycles to roughly 80% capacity), and self-discharge rate, all detailed in IEEE journals. For example, a 1C rate charges a 2 Ah battery in one hour, while higher rates can reduce cycle life due to heat and resistance buildup. Mastering these terms will boost your score on any battery trivia quiz section covering performance characteristics.
