Study Notes
Energy Storage System: Basic Principles of Batteries
- A battery is an electrochemical device that stores energy in the form of chemical energy, which can be converted into electrical energy when needed.
Types of Batteries
- Primary batteries: Non-rechargeable batteries that can be used once and then discarded.
- Secondary batteries: Rechargeable batteries that can be reused multiple times.
Lithium-Ion (Li-ion) Battery
- Construction: Consists of a positive cathode, negative anode, and electrolyte material separated by a porous membrane.
- Working: Lithium ions move from cathode to anode during discharge, and from anode to cathode during charging.
- Applications: Widely used in portable electronics, electric vehicles, and renewable energy systems due to high energy density, long cycle life, and low self-discharge rate.
Nickel-Cadmium (Ni-Cd) Battery
- Construction: Consists of nickel oxide hydroxide as the positive electrode, cadmium as the negative electrode, and potassium hydroxide as the electrolyte.
- Working: Nickel ions move from cathode to anode during discharge, and from anode to cathode during charging.
- Applications: Used in power tools, two-way radios, and other portable devices due to high discharge rate capability and long cycle life.
Energy Storage Systems
- Energy storage systems rely on batteries as a primary component
- Batteries convert chemical energy into electrical energy
Basic Principles of Batteries
- Batteries consist of one or more cells containing a positive electrode (cathode) and a negative electrode (anode)
- Chemical reactions occur between the electrodes, generating an electric potential difference
- Batteries can be classified into primary (non-rechargeable) and secondary (rechargeable) types
Lithium-Ion (Li-ion) Battery
- Construction: positive cathode (lithium cobalt oxide), negative anode (graphite), and an electrolyte (lithium salt dissolved in organic solvent)
- Working: lithium ions migrate from cathode to anode during discharge, and vice versa during recharge
- Applications: portable electronics, electric vehicles, renewable energy systems
Nickel-Cadmium (Ni-Cd) Battery
- Construction: positive cathode (nickel oxide), negative anode (cadmium), and an electrolyte (potassium hydroxide solution)
- Working: nickel oxide reacts with water to form nickel hydroxide, releasing electrons during discharge
- Applications: power tools, two-way radios, electric vehicles
Energy Storage Systems: Batteries
- Energy storage systems rely on batteries as a crucial component
- Basic principles of batteries involve the conversion of chemical energy into electrical energy
Types of Batteries
- Batteries can be classified into various types based on their chemistry and application
Lithium-Ion (Li-ion) Batteries
- Construction: Consist of positive cathode and negative anode separated by an electrolyte
- Working: Lithium ions move between electrodes during charging and discharging, facilitating energy storage and release
- Applications: Widely used in portable electronics, electric vehicles, and renewable energy systems due to their high energy density and long cycle life
Nickel-Cadmium (Ni-Cd) Batteries
- Construction: Comprise nickel oxide hydroxide as the positive electrode and cadmium as the negative electrode
- Working: Nickel oxide hydroxide releases electrons during discharging, which are accepted by the cadmium electrode
- Applications: Used in power tools, two-way radios, and other portable devices due to their high discharge rate capability and long lifespan
