BATTERY ENERGY STORAGE GLOSSARY | KEY TERMS A–Z

Energy Storage – Batteries and Rechargeable Batteries (A–Z)

LetterTermComprehensive Explanation
AAnodeThe electrode at which oxidation occurs during discharge. It releases electrons that flow through the external circuit. The material, structure and surface properties of the anode significantly influence charging speed, energy density, performance and service life.
BBatteryA functional energy-storage unit consisting of one or more electrochemical cells with a defined voltage, capacity and power output. Batteries may be primary, meaning non-rechargeable, or secondary, meaning rechargeable.
BBattery Management System (BMS)An electronic control and monitoring system that supervises individual cell voltages, temperatures, current flow, state of charge and other operating parameters. It protects the battery against overcharging, deep discharge, overcurrent, overheating and unsafe operating conditions.
BBuffer StorageAn energy-storage system used for short-term power supply, load balancing, peak shaving and the stabilisation of electrical grids, machines or industrial installations.
CCapacityA measure of the amount of electrical charge or energy that a battery can store. It is commonly expressed in ampere-hours or watt-hours and depends on factors such as discharge current, temperature, operating conditions and battery age.
CCathodeThe electrode at which reduction occurs during discharge. The cathode material has a major influence on cell voltage, energy density, power capability, safety and production costs.
CC-RateA measure of the charging or discharging current relative to the battery’s nominal capacity. A rate of 1C theoretically charges or discharges the battery within one hour. Higher C-rates enable faster power delivery but increase thermal and chemical stress.
CCellThe smallest electrochemical unit of a battery. A cell consists of an anode, cathode, electrolyte, separator and current collectors. Multiple cells can be connected to form modules, packs and complete battery systems.
CCycle LifeThe number of complete charge and discharge cycles a battery can perform before its usable capacity falls below a defined threshold, commonly 70 or 80 percent of its original capacity.
DDeep-Cycle BatteryA battery designed to withstand repeated deep discharges without suffering excessive damage. Deep-cycle batteries are particularly relevant for stationary storage systems, off-grid installations, marine applications and renewable-energy systems.
DDeep DischargeDischarging a battery below its permitted minimum voltage or state-of-charge limit. Deep discharge can cause irreversible chemical damage, capacity loss and a substantial reduction in service life.
DDegradationThe progressive loss of battery capacity, power capability and efficiency due to chemical ageing, mechanical stress and unwanted side reactions. Degradation is influenced by temperature, state of charge, C-rate, depth of discharge and the number of cycles.
DDepth of Discharge (DoD)The proportion of a battery’s total capacity that has been removed during discharge. For example, a DoD of 80 percent means that 80 percent of the available capacity has been used. Lower average discharge depths generally improve cycle life.
DDirect Current (DC)An electrical current that flows in one direction. Batteries naturally supply direct current. An inverter is required when the stored energy must be converted into alternating current for grid connection or AC-powered equipment.
EEfficiencyThe ratio between the energy supplied to a storage system and the usable energy subsequently delivered. Efficiency losses are mainly caused by electrical resistance, power electronics, thermal management and electrochemical processes.
EEnergy DensityThe amount of energy stored per unit of mass or volume, typically expressed in watt-hours per kilogram or watt-hours per litre. High energy density is especially important for mobile applications such as electric vehicles and portable electronics.
EEnvironmental ImpactAn assessment of the ecological effects of a battery throughout its entire life cycle, including raw-material extraction, manufacturing, transport, operation, reuse, recycling and final disposal.
EExtreme Fast Charging (XFC)A charging method that uses very high power levels to reduce charging times substantially. XFC is mainly relevant to electric vehicles and requires advanced cell chemistry, thermal management, charging infrastructure and battery control systems.
FFast ChargingA charging process using comparatively high electrical power to shorten charging time. It places greater demands on the cell chemistry, cooling system, charging infrastructure and battery management system and may accelerate degradation.
FFlow BatteryA stationary energy-storage technology in which energy is stored in liquid electrolytes held in external tanks. Power and energy capacity can be scaled largely independently, making flow batteries attractive for large and long-duration storage systems.
FFull Charge CycleA cumulative charging and discharging process equivalent to 100 percent of the battery’s usable capacity. A full cycle may occur in one continuous process or through several partial charging and discharging steps.
GGel BatteryA type of lead-acid battery in which the electrolyte is immobilised in a gel. Gel batteries are low-maintenance, resistant to leakage and suitable for different mounting positions, but they are relatively heavy and have limited energy density.
HHigh-Voltage BatteryA battery system operating at a comparatively high voltage, often 400 volts or more. Higher voltage reduces the current required for a given power level, thereby lowering cable losses, conductor sizes and component weight.
HHybrid Storage SystemA system that combines two or more energy-storage technologies, such as batteries and supercapacitors. The objective is to combine high energy capacity with rapid power delivery, improved efficiency or longer component life.
IInternal ResistanceThe electrical resistance within a battery cell or complete battery system. Low internal resistance enables high power output and reduces energy losses and heat generation during charging and discharging.
IInverterA power-electronic device that converts direct current from a battery into alternating current with a defined voltage and frequency. It is essential for grid-connected storage systems and for supplying AC-powered equipment.
JJouleThe SI unit of energy. One joule corresponds to one watt-second. In practical energy-storage applications, watt-hours and kilowatt-hours are more commonly used because they are better suited to typical battery capacities.
LLithium-Ion BatteryA rechargeable battery technology in which lithium ions move between the anode and cathode during charging and discharging. Lithium-ion batteries offer high energy density, high efficiency and long cycle life and are widely used in vehicles, electronics and stationary storage systems.
LLoss of PowerEnergy that is not available for useful output because it is converted into heat or consumed by auxiliary systems during charging, storage or discharging. Common causes include internal resistance, power electronics and cooling equipment.
MMemory EffectA reduction in usable battery capacity caused by repeated partial discharge patterns. The effect was particularly associated with nickel-cadmium batteries and is generally not significant in modern lithium-ion batteries.
MModuleA mechanically and electrically integrated assembly consisting of multiple battery cells. Modules may include sensors, cooling components, protective structures and monitoring electronics and are used as building blocks for larger battery packs.
NNominal VoltageThe typical operating voltage assigned to a cell or battery by the manufacturer. It serves as a reference value and may differ from the actual voltage depending on state of charge, load, temperature and cell chemistry.
OOverchargingCharging a battery beyond its permitted voltage or state-of-charge limit. Overcharging can accelerate ageing, generate excessive heat or gas and increase the risk of cell damage, fire or thermal runaway.
OOxidationA chemical reaction in which a substance releases electrons. During battery discharge, oxidation takes place at the anode and provides the electrons that flow through the external electrical circuit.
PPrimary BatteryA non-rechargeable battery designed for single-use discharge. Primary batteries typically offer long storage life, low self-discharge and simple handling but must be replaced after their stored energy has been consumed.
QQuality FactorAn overall evaluation of an energy-storage system based on characteristics such as efficiency, safety, reliability, cycle life, energy density, power capability and consistency of performance. The term is not a universally standardised battery parameter.
RRechargeable BatteryAn electrochemical energy-storage device that can be recharged and used for multiple charge and discharge cycles. It is also known as a secondary battery or accumulator.
RRecyclingThe recovery and processing of valuable materials from used batteries. Recycling reduces demand for primary raw materials, limits environmental impacts and supports a more circular battery supply chain.
RRound CellA cylindrical battery cell manufactured in standardised or application-specific dimensions. Cylindrical cells are mechanically robust, relatively economical to produce and widely used in consumer products, power tools and electric vehicles.
SSecondary BatteryA rechargeable battery designed for repeated charging and discharging. Secondary batteries are central to electric mobility, portable electronics, renewable-energy integration and stationary energy-storage systems.
SSodium-Ion BatteryA rechargeable battery technology in which sodium ions move between the electrodes. Sodium is widely available and can reduce dependency on certain critical raw materials, making the technology attractive for cost-sensitive stationary storage applications.
SSolid-State BatteryA battery technology that uses a solid electrolyte instead of a liquid or gel electrolyte. Solid-state batteries may offer improved safety, higher energy density and longer life, although large-scale commercial production remains technically challenging.
SState of Charge (SoC)The current amount of stored energy expressed as a percentage of the battery’s available capacity. The value is estimated by the battery management system using voltage, current, temperature and operating-history data.
TThermal RunawayAn uncontrolled, self-accelerating rise in cell temperature caused by exothermic chemical reactions. Thermal runaway can lead to gas release, fire or explosion and is one of the most serious safety hazards in battery systems.
UUndervoltageA condition in which the voltage of a cell or battery falls below its recommended operating range. It is often caused by excessive discharge and may result in reduced performance, protective shutdown or permanent cell damage.
WWatt-Hour (Wh)A unit of energy corresponding to one watt of power supplied for one hour. Watt-hours and kilowatt-hours are commonly used to specify the energy capacity of batteries and energy-storage systems.
YYieldThe total usable energy delivered by a storage system over a defined period or throughout its service life. It may be influenced by capacity, efficiency, degradation, operating strategy and system availability.
