New calcium-ion battery design delivers high performance without lithium

Scientists at The Hong Kong University of Science and Technology (HKUST) have reported a major advance in calcium-ion battery (CIB) research that could reshape how energy is stored and used in daily life. By incorporating quasi-solid-state electrolytes (QSSEs), the team developed a new type of CIB designed to improve both performance and sustainability. The technology could support applications ranging from renewable energy storage systems to electric vehicles. The work appears in ...
