Electrical Parameters of battery

Voltage:

  • Nominal Voltage: This is the standard voltage level at which the battery is rated and operates under normal conditions.
  • Open Circuit Voltage (OCV): The voltage of the battery when it is not connected to any load; essentially, the maximum voltage the battery can provide when not in use.
  • Cutoff Voltage: The minimum voltage at which the battery is considered fully discharged to avoid damage. 


Capacity:

  • Rated Capacity: The total amount of electrical charge a battery can deliver, measured in ampere-hours (Ah) or milliampere-hours (mAh).
  • Actual Capacity: The real-world capacity, which can be influenced by various factors such as temperature, discharge rate, and battery age.

Energy:

  • This is the total amount of work the battery can perform, calculated as the product of its capacity and voltage, and typically measured in watt-hours (Wh).

 

Internal Resistance:

  • The resistance within the battery that impedes current flow. Lower internal resistance generally means better battery efficiency and performance, especially under high loads.

Li-Ion and Li-Poly Batteries

 Lithium-Based Battery Construction 1. Anode: Typically made of graphite, sometimes combined with silicon or other materials to improve performance. 2. Cathode: Commonly uses lithium cobalt oxide (LiCoO2), lithium iron phosphate (LiFePO4), lithium manganese oxide (LiMn2O4), or other lithium compounds. 3. Electrolyte: Usually a lithium salt (such as LiPF6) dissolved in a mixture of organic solvents (like ethylene carbonate, dimethyl carbonate). 4. Separator: A porous membrane that prevents direct contact between the anode and cathode while allowing ionic movement. 5. Current Collectors: Typically made of copper (for the anode) and aluminium (for the cathode) to conduct electrical current to and from the external circuit. Working Principle 1. Charging: Lithium ions move from the cathode to the anode through the electrolyte, storing energy by intercalating into the anode material. 2. Discharging: The process reverses, and lithium ions move back to the cathode, releasing ...

lead-acid battery construction and adavantage

  A lead-acid battery is an electrochemical energy storage device, widely used in automotive and stationary applications, known for its ability to deliver high surge currents. Here are the main factors defining lead-acid batteries: Components Electrodes: Positive Plate: Made of lead dioxide (PbO₂). Negative Plate: Composed of sponge lead (Pb). Electrolyte: A sulfuric acid (H₂SO₄) solution that facilitates the chemical reactions. Separator: A material that prevents physical contact between the positive and negative plates while allowing ionic movement. + Container: Typically made of durable plastic, housing the electrodes and electrolyte. Chemical Reactions: Discharge Reaction: At the anode:  Pb + HSO4– → PbSO4 + H+ + 2e– At the cathode:  PbO2 + 3H+ + HSO4– + 2e– → PbSO4 + 2H2O   During discharge, both electrodes react with sulfuric acid to form lead sulfate (PbSO₄) and water (H₂O). Charge Reaction: Negative: 2e– + PbSO4(s) + H3O+(aq) –> Pb(s) + HSO4– + H2O(l) (red...
