Development of a lithium-air battery with an energy density over 500 wh/kg: One of the world’s highest energy densities achieved
NIMS and Softbank Corp. have developed a lithium-air battery with an energy density over 500Wh/kg — significantly higher than currently lithium ion batteries. The research team then confirmed that this battery can be charged and discharged at room temperature. In addition, the team found that the battery developed by the team shows the highest energy […]
Significant energy savings when electric distribution vehicles take their best route
Range anxiety with electric commercial vehicles is real, since running out of battery can have serious consequences. Researchers at Chalmers University of Technology, Sweden, have developed tools to help electric delivery-vehicles navigate strategically to use as little energy as possible. The secret lies in looking beyond just the distance travelled, and instead focusing on overall […]
Scientists discover how oxygen loss saps a lithium-ion battery’s voltage: Measuring the process in unprecedented detail gives them clues to how to minimize the problem and protect battery performance
When lithium ions flow in and out of a battery electrode during charging and discharging, a tiny bit of oxygen seeps out and the battery’s voltage — a measure of how much energy it delivers — fades an equally tiny bit. The losses mount over time, and can eventually sap the battery’s energy storage capacity […]
