Brimming with the promise of a greener, more efficient future, SK On, a trailblazer in the realm of energy technology, unveils groundbreaking advancements in all-solid-state battery research. Calling these powerhouses “dream batteries” is no exaggeration. The company’s relentless pursuit of battery excellence has culminated in a series of innovative findings published in prestigious international journals, signaling a quantum leap in battery longevity and performance.
In the electrifying field of energy storage, the lithium metal anode stands out, shimmering with potential. Known for its impressive capacity, outperforming existing graphite tenfold, it serves as the cornerstone of all-solid-state batteries. Despite its promise, this superlative material has long wrestled with a critical flaw: fleeting lifespans. Yet, SK On’s latest explorations, conducted alongside Prof. Kim Dong-won of Hanyang University, have carved a path through this challenge.
Imagine enveloping the delicate lithium in a protective armor. The process is almost alchemical—dipping the anode into a mystical solution that strips away harmful residues, before adorning it with a robust shield of lithium nitride and lithium oxide. This scientific wizardry bestows the battery with a newfound resilience, allowing it to endure over 300 charge-discharge cycles at room temperature—a lifespan thrice as lengthy as its predecessors.
But the innovation saga doesn’t halt there. A parallel stream of insights flows from SK On’s collaboration with Yonsei University’s Prof. Park Jong-hyeok, diving into the intricacies of polymer oxide composite batteries. Here, the team disentangles the mysterious bond between the curing time of gel polymer electrolytes and battery performance. Their findings reveal a simple truth: patience pays off. Batteries allowed a leisurely 60 minutes of thermal curing exhibit far superior durability compared to those rushed through a mere 20-minute process.
The elegance of quantum mechanical density functional theory (DFT) calculations further unravels the enigma of performance degradation, painting a vivid portrait of chemical interactions at the atomic level. By precisely illuminating the path of degradation, these calculations equip engineers to prolong the life of polymer oxide composite batteries, edging us ever closer to sustainable energy solutions.
“This achievement is a testament to SK On’s unwavering commitment to research and collaboration,” declares Park Ki-soo, head of the company’s Research and Development Division. His words echo a sentiment of triumph and hope, as these advancements lay a solid foundation to surmount technical hurdles that once seemed insurmountable. As the global spotlight shifts to next-generation batteries, SK On stands poised at the vanguard, crafting a future where energy is not just stored, but celebrated.
