Graphene vs Lithium Batteries: The future of phone industry?


So, while lithium-ion batteries have been holding down the fort for a while now, graphene batteries are swooping in, ready to shake things up. Who knows, maybe soon we’ll be laughing at the days when we had to charge our phones every few hours.

Key Takeaways

  1. Lithium-ion battery: Lithium-ion batteries have a cathode (lithium cobalt oxide), an anode (graphite), and an electrolyte that allows charged particles to flow between them.
  2. Graphene Benefits: Graphene’s high conductivity and flexibility lead to faster charging and higher energy storage, though high production costs limit widespread use.
  3. Graphene-Composites: Graphene-composite batteries, like those in the iQOO 12, enhance lithium-ion batteries, offering improved capacity and longevity.

Lithium-ion Batteries

Think of it like a tiny, high-tech sandwich, with a cathode, an anode, and an electrolyte holding it all together.

First up, we’ve got the cathode. It’s usually made from a fancy material called lithium cobalt oxide. This part of the battery is where all the action happens – it’s where the storing and releasing energy takes place.

Next, we’ve got the anode, which is like the sidekick to the cathode. This part is typically made from good ol’ graphite, the same stuff you find in your pencils. The anode’s job is to hang out and chill until it’s time to jump into action and help store or release energy.

Last but not least, we’ve got the electrolyte, which is like the secret sauce holding everything together. It can be a liquid or a gel.

The electrolyte’s job is to make sure that the charged particles can flow freely between the cathode and the anode, keeping the whole battery going smoothly.

No Memory Effect

Lithium-ion batteries are not big fans of memory effect. What’s memory effect, you ask? Well, it’s like when your battery starts to “remember” its capacity.

The battery does it when you recharge it without completely discharging it first. This can affect the longevity of the battery.

But with lithium-ion batteries, you can charge your phone whenever you feel like it, even if it’s not totally dead, without worrying about messing up its mojo.

And get this: these batteries have some serious staying power. Take an iPhone, for example. Even after it’s been through the battery ringer about 500 times, it can still hold onto about 80% of its original charging capacity.

First off, their charging capacity is a bit like a tiny gas tank – it can only hold so much juice. So, if you’re planning on going off the grid for a while, you might find yourself hunting for outlets.

Then there’s the size issue. These batteries aren’t exactly the definition of sleek and slim.

And last but not least, their lifespan is, well, modest. Like a shooting star, they burn bright but don’t stick around forever.

Fast Charging’s Impact on Phones Battery – Detailed Analysis

What is Graphene?

Picture this: graphene is like a super-thin, super-strong sheet made up of carbon atoms. We’re talking thinner than a strand of hair and extremely tough.

Now, what makes graphene so special? Well, for starters, it’s got some serious street cred when it comes to conductivity. This stuff conducts electricity and heat like nobody’s business. It’s like having a superhighway for electrons and heat waves to zoom through.

But wait, there’s more! Graphene is also super flexible. You can bend it, twist it, and fold it like a piece of paper without breaking a sweat.

Oh, and let’s not forget about its weight – or lack thereof. Graphene is relatively light weight, which makes it perfect for all sorts of applications where weight matters.

Graphene Batteries

In graphene batteries, they swap out one of the traditional electrodes for a fancy hybrid material that includes our buddy graphene.

Now, here’s where graphene swoops in to save the day again. See, graphene’s ultra-high conductivity and super-thin structure make it the ideal material for storing and releasing energy in the blink of an eye.

Moreover, all the benefits of graphene translates into graphene batteries like its light weight and flexibility.

This means faster charging speeds. Like, so fast you’ll barely have time to finish your coffee before your phone is back at 100%. And it doesn’t stop there – graphene batteries could also pack a serious punch when it comes to energy storage capacity.

Graphene vs Lithium-ion Batteries

Now, when it comes to electrical conductivity, graphene takes the cake. It’s like the speedster of the material world, zipping electrons around extremely fast.

This means that graphene batteries could potentially pack more punch in terms of power, allowing your smartphone to keep up for a long time.

But here’s where things get interesting: because graphene is so good at conducting electricity, it could allow smartphone designers to get a little creative.

Picture this: phones that are thinner than a credit card, or ones that offer more battery capacity without taking up all the space. The complete shift to graphene batteries could be an inflection point for mobile phone industry!

With greater electrical storage capacity and faster-charging speeds, graphene batteries packing a punch that’ll leave your old lithium-ion battery in the dust.

Ah, here’s the plot twist: while graphene batteries might sound like the holy grail of energy storage, they’re not without their challenges – namely, the cost of production.

You see, right now, making graphene is kind of like printing money – except you’re spending a lot more than you’re making. The production costs are sky-high, which makes it tough for graphene batteries to break into the mainstream.

A solution to this is graphene-composite batteries. Instead of going all-in on pure graphene batteries, researchers are getting creative and using graphene to supercharge traditional lithium-ion batteries.

So, while graphene batteries might still be a ways off from becoming the norm, graphene-composite batteries are like the stepping stone to greatness.

Smartphones with Graphene Batteries

While graphene batteries are still finding their feet in the smartphone world, there’s already some buzz about a new player on the scene – the iQOO 12.

Now, this device is packing some serious heat in the battery department. With a whopping 5,000 mAh battery under the hood.

But here’s where things get interesting: the iQOO 12 isn’t just any old battery – it’s a graphite-enhanced battery (Graphite is multiple combined layers of graphene).

The iQOO 12 promises to retain at least 80% of its capacity after a staggering 1,600 cycles.

Ah, here’s the reality check: while we’ve seen some tantalizing glimpses of graphene’s potential, we’re still not quite ready to welcome graphene batteries into the smartphone family with open arms.


While lithium-ion batteries have been our trusty companions for years, the arrival of graphene batteries could mark the beginning of a whole new chapter. But it is not going to happen quick.

Sure, the iQOO 12 and other examples show us what graphene can do, but we’re still a ways off from seeing it become the norm.

Note: Any verdict given by us on any of the companies, or specs of a device is subjective. Our preferences can be different from yours, so be sure to conduct your own research to make a decision that is good for you.
