Welcome to Basic Electrical and Electronics Engineering (BTES106)!
In this video, we’ll learn about NiCd Batteries – Construction, Working & Applications, a key part of Unit 2: Measurement of Electrical Quantities.
📌 In This Video:
Introduction to Nickel-Cadmium (NiCd) Batteries
Construction: electrodes, electrolyte, and design
Working principle with reactions and cell voltage (1.2V per cell)
Charging & discharging behavior + memory effect explained
Advantages: durability, high cycle life, fast charging
Limitations: toxic cadmium, memory effect, lower energy density
Applications: aviation, emergency lighting, medical backup, power tools
⚡ Key Highlights:
NiCd = rechargeable secondary battery
Works well in cold temperatures & high current loads
Suffers from memory effect if not fully discharged before charging
Still used in critical, rugged applications despite lithium-ion dominance
