Overview
🎯
Why it matters
Battery technology in EVs, corrosion prevention in structures, polymer design in plastics — all chemistry. This subject connects molecular science to real-world engineering products.
💼
Placement relevance
Relevant for core companies: Chemical, Petroleum, Materials Science. For CS students, understanding battery chemistry helps in IoT/hardware roles. Generally lower weightage in tech interviews.

Previous Year Questions
Unit 22023 · End Semester8 marks
Explain the working of a lithium-ion battery. Write the reactions at anode and cathode during charging and discharging.
Exam Strategy
⚗️
Focus on applications
Exams ask real-world applications: How batteries work, why iron rusts, how electroplating works. Connect theory to practical examples.
🧪
Chemical equations must balance
Every reaction question requires balanced equations. Check: same number of atoms on both sides, charge balanced. Practice writing half-reactions for electrochemistry.
