aluminum-ion

Scientists in South Korea and the UK demonstrated a new cathode material for an aluminum-ion battery, which achieved impressive results in both specific capacity and cycle life. The material allows researchers to better take advantage of aluminum’s energy storage characteristics, and produce batteries with much higher capacity.

Scientists in the U.S. developed an aluminum battery that demonstrates better than 99.5% reversibility, and could offer “up to 10,000 error-free cycles”. By incorporating a substrate of carbon fibers into the anode design, the group gained better control over chemical bonds that form as the battery charges, leading to greatly improved performance.

Scientists in China and the United States investigated the inner workings of aluminum-ion batteries. With new insights into mechanisms at work within the battery during cycling, the group was able to demonstrate a battery capable of ultrafast charging, with the highest capacity so far reported for an aluminum battery.

Scientists at the University of Maryland have developed an organic polymer electrode which they claim demonstrates stable function for a sodium-ion battery over 50,000 cycles and also offers encouraging performance in magnesium-ion and aluminum-ion storage devices.
