 
You might have experienced similar situation either with your laptop or with mobile  or electric vehicle friends
What is common in all these? who is responsible for controlling our mood nowadays?
Portable electronic devices, electric vehicle or renewable energy storage all are dependent on safe
efficient and inexpensive
Energy storage system just as a pinch of salt is necessary for all recipes
Every one of you, I repeat,
Every one of you is carrying that pinch of salt in your pocket! Your mobile battery- “The Li-ion battery.”
The Li-ion battery can be  a promising choice due to its high energy density
Can you imagine your life without smartphones?
without lithium-ion battery in 21st century
I don't think so
What makes this small electrochemical energy storage device so special? It’s A Bollywood Love story  happening right now
Inside the battery we have a handsome hero the cathode and the beautiful princess the anode
Who are ready to fall in love with each other and exchange their hearts
that is electrons
But wait how could be a battery love story is possible without the best friend, the Electrolyte!
Super hero of our story is lithium
lightest of all metals though lithium is known for about
200 years this super hero has started using his power since last 25 years
Adventurous journey of our superhero begins as soon as you connect your battery for charging
We, the Mumbaikars,  have to make adventurous journey
every day we use local train to commute between residents and
workplace
similarly during charging the lithium ions move from cathode to the anode and
Electrolyte act as a local train. There is a separator which permits only lithium-ion  but not
Electron.Hold on! It is a love story,  We must have happy ending!
Yes. We have the compensating electron moves through the external circuit
Your battery is fully charged when the anode hosts  all the lithium ions now during discharge the exactly reverse process
Happens the lithium ions moves from anode to the cathode and flow of electron through the external circuit
Generate current, we all know love is complicated
#Relationship #Its Complicated and is true in case of
lithium-ion battery also some of the major challenges are long time for charging, quick discharge, material, cost etc.
however the most important One is the safety. There is a battery management system
Just like a stationmaster to control
charging and discharging of lithium-ion battery now imagine if this
stationmaster fails in his duty then
BOOM... An explosion!
To avoid this, we need a little bit of Math, a little bit of electrochemistry,
One spoon of material science
The perfect recipe of lithium ion battery is ready the primary focus of this recipe is to reduce cost
Increase battery life without violating the safety norms
So next time when you are angry at your discharged battery. Just remember this story have some love and
Respect for the Lithium-ion battery, thank you
