Read the scientific paper ” Simulating charging characteristics of lithium iron phosphate” or simply read the following if you are not a super boffin.
Has this ever happened to you…
You’re out and about, you may have had a couple of more beers than you said you would, you should probably have been home by now, then your partner calls, and just as you mumble “hello —BAM!
Your phone dies. 😱
Your battery gave up on you again, and now you are in even more trouble.
But what if I told you that quantum computers might help your battery last way longer and charge way faster?
That’s exactly what some super-smart scientists have been working on.
They’ve been using a special kind of quantum computer called a quantum annealer to study the way lithium-ion batteries charge.
And no, a quantum annealer isn’t a kitchen appliance—it’s a cutting-computing platform that helps solve really tricky problems.
There are a few Quantum companies that use annealing for their computational processes, one of them D-Wave I covered recently, a story for another day perhaps, but for now lets talk about your handset battery.
Let’s break it down.
Batteries Are Like a Tiny Game of Musical Chairs 🎵🪑
Batteries store energy by shuffling tiny particles called ions around. Imagine a game of musical chairs.
The lithium ions (Li⁺) are the players, and they move between different seats (called sites) inside the battery.
- When you charge your battery: The lithium ions move from one side of the battery to the other, taking a seat in new spots.
- When you use your phone (discharging): They jump back, releasing energy that powers your device.
But here’s the problem—these lithium ions don’t always sit in the best spots.
Sometimes, they bunch up awkwardly or get stuck, making your battery slow to charge and wear out faster.
In old phones, like mine the wear and tear of many a furious charge at zero battery makes them even less able to hold their charges the longer you have them.
This is where quantum computers come in.
The Superpower of Quantum Computers 🦸♂️
A normal computer, like the one you’re using right now, solves problems step by step—kind of like checking every possible way to arrange the lithium ions one by one.
Slow.
A quantum annealer, on the other hand, can explore millions of possibilities at once!
It’s like trying every single move in a chess game simultaneously and having software to help you identify instantly what the best move is.
Scientists used this quantum tech to figure out the absolute best way for lithium ions to sit inside the battery while charging.
This is just one optimisation problem among millions that Quantum will help us solve.
This could lead to:
✔ Faster charging times (like, minutes instead of hours!)
✔ Longer battery life (your phone could last days instead of hours)
✔ More efficient electric cars (because those also run on lithium batteries!)
How Did They Do It? 🧪
The researchers created a computer model of a battery and used a quantum annealer to figure out the best lithium-ion seating arrangement.
They used a Coulomb energy model, which is just a fancy way of saying:
👉 They calculated how the ions push and pull each other, so they don’t get in each other’s way.
Then, they let the quantum computer play around with different ways the ions could arrange themselves and found the absolute best one.
The results matched real-world battery behaviour, which means this method actually works and it is going to be applied in production.
What’s Next? 🔮
This research is just the beginning. If we keep improving quantum simulations, we might see:
⚡ Supercharged phone batteries that last for days!
🚗 Electric cars that charge in minutes!
🌍 A greener planet with better energy storage!
And to think—it all started with a fancy game of musical chairs inside a quantum computer. 🎶
So, next time your phone battery dies at the worst possible moment, just remember—science is working on it! 🔬
