We may soon say goodbye to rumors of planned obsolescence if Apple decides to apply this tech.
TDK Corporation, one of Apple’s key suppliers, has revealed a new material for solid-state batteries that can improve energy storage in small devices.
The new technology, called CeraCharge, uses oxide-based solid electrolytes and lithium alloy anodes, making the batteries very safe for use in wearable devices.
Plus, it can store an estimated 1,000 Watt hours per liter (Wh/L). That’s more than twice the energy storage of the lithium-ion batteries currently used in smartphones and wireless earbuds!
How Can This Affect AirPods?
Now, you’re probably wondering – “What does this mean for my AirPods?”
Well, if Apple decides to jump on this technology, we could be looking at some serious improvements in battery life. And, we might even see more compact AirPods designs or additional features that would’ve been power-hungry pipe dreams before.
TDK isn’t just stopping at increasing energy density, though.
They’re also targeting to push the battery capacity through multi-layer lamination technology and expand the operating temperature range.
This could mean AirPods that may not only be more powerful but also more versatile and durable. You’ll practically be able to use them whether you’re in the desert or the arctic.
Plus, there’s also an eco-friendly angle to all this.
TDK’s new batteries might replace coin cell batteries, which aligns with EU rules pushing for rechargeable options. This could improve both sound quality and reduce environmental impact.
Solid-State vs Lithium-Ion Batteries
Solid-state batteries aren’t just a minor upgrade. They’re a whole different ballgame compared to the lithium-ion batteries we’re used to.
For one, they can store much more energy – potentially 400Wh/kg compared to about 250Wh/kg in lithium-ion batteries.
But lasting longer isn’t the only goal.
They’re also safer because they use solid materials instead of liquid, which makes them less likely to leak or catch fire. This makes them especially good for devices like AirPods that people wear close to their bodies.
And, let’s not forget about longevity. Solid-state tech might just be the answer to the dreaded battery degradation that most of us have experienced with AirPods. Yet, this is still being studied to be verified.
So Why Does Apple Still Use Lithium-Ion Batteries for AirPods?
Solid-state batteries aren’t exactly new. So, you might be wondering: why Apple hasn’t already made the switch?
Well, as exciting as new tech can be, the reality is that lithium-ion batteries are still the practical choice for now.
Despite the bad rap, lithium-ion batteries do have their perks.
These batteries are well-tested, easy to get, and cheaper to make – all important for mass-produced devices like AirPods.
They can be charged whenever without losing capacity, which is pretty convenient for our on-the-go lifestyles.
But, they’re not without their quirks. They don’t like heat or being overcharged, and they slowly lose capacity over time, as many AirPods users have noticed.
Yet, changing to solid-state batteries isn’t as simple as just swapping parts.
Apple would need to completely redesign AirPods to work with the new batteries. Also, solid-state batteries are still being tested, especially for small devices like earbuds. So, the benefits are still pretty much theoretical at this point.
Eitherway, Apple hasn’t said anything about plans to use solid-state batteries in their products. Given how much they like to improve their technology, they’re probably watching these developments closely, though.
While we can’t say for certain when (or if) we’ll see solid-state AirPods, one thing’s for sure – the future of portable audio is looking brighter (and longer-lasting) than ever.
