次世代電池とは？
GMS is applicable to electrodes in next-generation batteries, including all-solid-state, lithium-air, and lithium-sulfur batteries. With GMS, enhanced performance and extended lifespans in next-generation batteries are expected.
代表的な次世代電池へのGMSの適用例
Solid-State Batteries
Solid-state batteries, which improve the safety of lithium-ion batteries by replacing liquid electrolytes with solid ones, have faced a significant challenge. As the active material repeatedly expands and contracts during charge and discharge cycles, maintaining consistent contact between the solid electrolyte and the active material becomes difficult, leading to increased resistance in battery reactions. By incorporating GMS as a conductive additive within the electrode, the expansion and contraction of the active material can be absorbed, ensuring sustained contact between the solid electrolyte and active material and preventing performance degradation.
Lithium-Air Batteries
Lithium-air batteries are next-generation energy storage devices anticipated to achieve an energy density several times higher than that of lithium-ion batteries. However, rapid degradation of conventional carbon cathodes and electrolytes has severely limited their cycle life. Utilizing GMS in the cathodes of lithium-air batteries enables a significant enhancement in both cycle life and capacity compared to traditional carbon materials such as carbon black, carbon nanotubes, and activated carbon.

Conventional carbon supports have been used in fuel cell electrodes, but these materials have suffered from insufficient high-voltage resistance. Although firing can improve the high-voltage resistance of carbon supports, it significantly reduces their surface area, compromising their ability to effectively disperse catalysts.
GMSを用いるメリット
GMS is a unique carbon material that maintains its porosity—and thus its high specific surface area—even after firing, while exhibiting exceptional high-voltage resistance. As a result, using GMS as a catalyst support for fuel cells is expected to overcome the limitations associated with conventional supports.
