The promotion of electric cars has dramatically increased the demand for lithium-ion batteries. However, cobalt and nickel, the main cathode materials for the batteries, are not abundant. If the consumption continues, it will inevitably elevate the costs in the long run, so scientists have been actively developing alternative materials. A joint research team co-led by a scientist from City University of Hong Kong (CityU) has developed a much more stable, manganese-based cathode material. The new material has higher capacity and is more durable than the existing cobalt and nickel cathode materials - 90% of capacity is retained even when the number of charging-recharging cycles doubled. Their findings shed lights on developing low cost and high efficiency manganese-based cathode materials for lithium-ion batteries.

Lithium ion batteries use liquid electrolytes that have several drawbacks, which can be overcome by all-solid-state lithium secondary batteries (ASSBs). However, it is important to find efficient electrode materials for ASSBs. A research team from Japan has recently developed a novel electrode material for ASSBs by combining lithium sulfate and lithium ruthenate, which results in improved performance. The scientists hope that their novel approach will guide future research and the eventual commercialization of such high-capacity batteries.

Polyacrylamide gel electrophoresis enables high-resolution separation of proteins extracted from biological samples, but it requires more than one day of pretreatment to recover the separated proteins trapped inside the gel for detection by mass spectrometry. BAC-DROP, our novel electrophoresis technology, uses a dissolvable form of polyacrylamide gel, which allows sample pretreatment to be completed in about 5 hours. The developed technology will enable the rapid diagnosis of viruses and disease protein markers.
