Researchers at the Hong Kong University of Science and Technology have built a calcium-ion battery that retains roughly three-quarters of its capacity after 1,000 charge-discharge cycles, a result ...

With the use of electric vehicles and grid-scale energy storage systems on the rise, the need to explore alternatives to lithium-ion batteries has never been greater. Researchers have recently ...

Researchers at Tohoku University in Japan have developed a prototype calcium battery with a long cycle life of more than 500 charge-discharge cycles. The battery was developed using a hydride-based ...

Researchers at The Hong Kong University of Science and Technology have developed a new type of calcium-ion battery that could challenge lithium-ion technology by improving stability and performance.

Organic carbon and calcium carbonate are two critical components of the ocean's carbon cycle. Organic carbon originates mainly from phytoplankton photosynthesis, which is part of a complex biological ...

Lithium has reigned in the battery world for decades. Researchers have tried for years to make a cheaper, more sustainable successor to lithium-ion batteries by using the element’s more common ...

A research group at Japan’s Tohoku University has developed a prototype calcium metal rechargeable battery capable of 500 cycles of repeated charge-discharge – the benchmark for practical use. However ...

Forward-looking: Despite being a relatively rare element, lithium is still the king of materials when it comes to rechargeable battery technology. Calcium is 2,500 times more abundant than lithium, ...
