The Japanese company TDK recently announced an important breakthrough in battery technology and, therefore, inautonomy of the devices (wearable in this case). Thanks to a new material, the CeraCharge batteries they reach an energy density of 1,000 Wh/L, a remarkable result when compared with traditional solid-state batteries.
This advancement could mean much longer battery life for smartwatches, wireless earbuds and other wearable devices.
Concentrated Energy
Energy density, or the amount of energy stored per unit volume, is fundamental to the autonomy of a device. At 1,000 Wh/L, the new TDK batteries far outperform current wearable lithium-ion batteries, which typically have a density between 200 and 400 Wh/L. This difference could translate into a double or even fivefold increase in battery life.
But how does the new technology work? Without getting into too many technicalities, TDK explains that CeraCharge batteries use a solid ceramic electrolyte, which offers safety and reliability advantages over traditional liquid electrolytes. The absence of flammable liquids reduces the risk of leaks and fires. Furthermore, these batteries apparently can withstand up to 1,000 charging cycles, guaranteeing a long life.
TDK is currently working on battery cell development, packaging design and mass production. Although no precise dates for commercialization have been given, this technology promises to free wearable devices from the current limits of autonomy. Imagine smartwatches that last days without charging or wireless earbuds that accompany you for a full day of listening. It wouldn’t be bad especially for wearable rings, especially now that big brands like Samsung are ready to present their products: on the other hand, the Samsung Galaxy Unpacked is approaching: what do you expect from these new battery technologies? Are you confident or is there no future without nuclear batteries?
