Smart Storage Search (3S Intermingled) Being a science student, I came to know about energy cell when I first tried to memorize the electrochemical seriesECE in short. Use of sign in mathematical conversions was trickier for a while. But that did not deter me at all in any way. Later, I mastered on ECE series skilfully and studied elaborately on Lithium chemistry, which guided me to produce this energy cell book specifically on Lithium Ion Battery (LIB). My hand on experience on energy cells like Zn-Cu, or Pb-Sulfuric acid, or DRY cell perfected me to rewrite energy cell reactions here to use for demonstration.
