Our paper on an all-solid-state sodium (Na)-ion secondary battery using a glass-ceramic cathode was ranked in the top three most downloaded papers*1 in 2020 in Scientific Reports published by Nature Research, an English scientific journal.
We developed an all-solid-state Na-ion secondary battery using a glass-ceramic cathode, and succeeded in operating it at room temperature in 2017 for the first time in the world as an oxide-based all-solid-state battery. In 2020, we proved that this battery could achieve practical-level performance by greatly reducing the electrical resistance inside the battery, and a paper on the research results appeared in Scientific Reports.
The all-solid-state Na-ion secondary battery we have developed uses sodium, which is an abundant resource, and does not use flammable electrolytes, while lithium (Li)-ion secondary batteries are subject to concerns about the unstable supply of lithium resources and safety risks such as flammability. Accordingly, our new battery can resolve the problems associated with conventional Li-ion batteries. Hereafter, we will continue to endeavor to accelerate commercializing of next-generation secondary batteries.
