Introduction

The invention of battery not only brought about the advent of portable technology, but also the possibility of having a consistent supply/flow of electricity day in and day out. Batteries are so pervasive in today's world that we couldn't have imagined a past without it and cannot stop imagining a future wherein which batteries are not a part of. Now, in this part of the course, we would like to give you a brief objective on how the future of batteries looks like. Yes, various innovations in the field of technology have been subject to the classic trauma of over-promise and under-deliver, just take a look at what wonders we expected from plastic in 21st century during its innovation phases and where we are today! But still we are moving towards it, just a tad slower than what we'd have wanted. Same is the case with battery technology, we have been pondering over it's innovations: like super-capacitors, Graphene powered batteries for a few years/decades now, but they don't seem to be near us for the next few years to come. But that doesn't mean wonders haven't happened in these fields and that we should turn a blind-eye to the developments happening in it. And maybe who knows, we would be the ones making some of the major contributions to making someone's future, our present.

In this part of the course we would like to take you through the past and present of batteries, not going quite that into the depth of it, so that we can appreciate and understand what the over-promise of future batteries looks like and what to expect from them. The course would roughly walkthrough in the following manner:

1. A brief history into battery

2. The workings of a battery

3. Various promising technologies of the future

Let's just get a small overview on what we know about batteries:
