Summary of the clip:
Why does a crystal-oriented solid-state battery charge to 80% in 15 minutes without a charge controller?
Standard lithium-ion chemistries require sophisticated Power Management ICs (PMICs) and current control loops to prevent lithium plating during fast charging. Due to the high ionic conductivity of the crystal-oriented ceramic electrodes, this battery can safely reach an 80% state of charge in only 15 minutes.
This rapid transport mechanism simplifies the entire electrical design of the host wearable device. By bypassing the need for dedicated charging control ICs, system designers can significantly reduce BOM cost and circuit board real estate.
Additionally, the crystal orientation ensures robust discharge kinetics even in harsh environments. The cell can continuously deliver over 100 mA at -20°C with only a 10% state of charge, facilitating high-power wireless communication protocols.
In this short video, you can learn:
* 80% fast-charging capability within 15 minutes
* Elimination of complex charger and current-control ICs to minimize BOM
* Sub-zero discharge performance supporting high peak-current IoT communication
📋 **Clip Abstract** This clip highlights the electrical performance benefits of NGK's crystal-oriented ceramic batteries in wearable applications. Understand how high ionic conductivity enables ultra-fast charging without control ICs while maintaining high discharge rates at -20°C.

How can crystal-oriented ceramic plates replace organic binders in solid-state lithium batteries?
How can crystal-oriented ceramic plates replace organic binders in solid-state lithium batteries?
Traditional lithium-ion batteries rely on multi-layer designs and organic binders, which introduce safety risks and volume constraints. By utilizing a proprietary semi-ceramic, crystal-oriented ceramic plate for the cathode, NGK has engineered a monolithic, porous active material structure that functions with only a minimal amount of liquid electrolyte.
This crystal orientation aligns the microstructural pathways, allowing lithium ions to migrate smoothly even from deep within the electrode. Consequently, this enables a highly efficient single-layer structure that significantly reduces the total cell thickness.
Furthermore, the latest evolution of this technology, the ET series, extends this crystal-oriented ceramic design to both the cathode and the anode. This elimination of organic binders and conductive additives significantly reduces degradation and mitigates ignition risks.
In this short video, you can learn:
* Ceramic-based crystal-oriented electrode structure
* Elimination of organic binders and conductive additives
* Transition from single-electrode ceramic to dual-sided (anode/cathode) ceramic architecture
📋 **Clip Abstract** This clip details how NGK's crystal-oriented ceramic plates eliminate organic binders and conductive additives to optimize lithium-ion pathways. You will discover how this material-level innovation enables thin, single-layer battery designs for tight physical envelopes.

Can a wearable battery survive a nail penetration test with zero thermal runaway or swelling?
Can a wearable battery survive a nail penetration test with zero thermal runaway or swelling?
Safety and physical stability are paramount for batteries worn directly on the human body or integrated into flexible medical patches. Under extreme mechanical abuse conditions, such as direct nail penetration or complete folding, NGK's semi-solid-state ceramic battery exhibits no ignition and virtually zero temperature spike.
Beyond catastrophic safety events, long-term swelling remains a persistent failure mode in conventional pouch cells used in wearable electronics. Because this ceramic battery features a semi-solid-state structure with minimal organic content, it fundamentally eliminates outgassing and expansion.
Through advanced outgassing control during the manufacturing process, these cells maintain structural integrity over years of operation. This dimensional stability allows product designers to omit the typical physical expansion gaps required in device enclosures.
In this short video, you can learn:
* Thermal stability and zero temperature rise under nail penetration and folding tests
* Mitigation of long-term battery swelling through semi-solid-state design
* Outgassing control and minimal organic content in ceramic manufacturing
📋 **Clip Abstract** This video segment reviews the safety and dimensional stability of NGK's EnerCera semi-solid-state batteries under mechanical stress. Learn how eliminating organic materials prevents swelling and heat generation, making it ideal for on-skin electronics.
