Bateri Keadaan Pepejal di Landasan untuk Realiti

Solid-state batteries are a promising technology that offers advantages such as higher energy density and improved safety compared to traditional lithium-ion batteries. However, there have been significant challenges to overcome in order to make them a viable option. Scientists at Osaka Metropolitan University have made a breakthrough discovery that could accelerate the development of solid-state batteries.

One of the major obstacles faced by solid-state batteries is the development of cracks in the solid electrolyte during charging and discharging cycles. These cracks create pathways for dendrites to penetrate between the electrodes, leading to short circuits and reducing the durability of the batteries. In order to address this issue, researchers have been focused on finding ways to prevent dendrite formation and improving electrolyte research.

Recent breakthroughs in dendrite formation research have shed light on what causes it and how to control its growth. By creating controlled cracks in the solid electrolyte, scientists have found that dendrites can be directed away from the opposite electrode, preventing short circuits. This counterintuitive approach has shown promising results in preventing dendrite formation.

Additionally, scientists at Osaka Metropolitan University have found a way to significantly increase ion conductivity in solid electrolytes at room temperature. This discovery has been a major advancement in solid-state battery development, as it improves battery power and reduces recharge time. The researchers achieved this by focusing on the heating rate during the crystallization process of Li3PS4, a glass-like material critical for solid-state batteries.

The results of this research, which were published in the Journal of the American Chemical Society, offer hope for the design of higher-performance solid electrolyte materials. While solid-state batteries remain a distant dream, these advancements bring us one step closer to their realization.

It’s worth noting that some companies claim to offer solid-state batteries, but they are actually semi-solid batteries that combine the advantages of solid and liquid electrolytes. These semi-solid batteries are considered an intermediary step before fully solid-state batteries become production-ready.

While solid-state batteries are not yet commonplace, it’s important to remember that similar skepticism surrounded lithium-ion batteries in the past. Over the past three decades, lithium-ion batteries have made tremendous advances in terms of durability and energy density. With continued research and development, solid-state batteries have the potential to become a reality in the future.
