ppm) with a nominal Li/Mg selectivity >45 million. ppm) and an abundance of interfering ions (i.e., 13000 ppm of sodium, magnesium, calcium, and potassium ions, among others). Instead, the lithium concentration and the ratio of lithium to other multivalent ions, such as Mg 2+ and Ca 2+ , are the key factors to consider.

New high energy, highly stable cathode for sodium-ion batteries

Green Car Congress

F 0.7 , for sodium-ion (Na-ion) batteries (NIBs). This new material provides an energy density of 600 Wh kg –1 , the highest value among Na-ion cathodes. Recently, attention has been refocused on room-temperature Na-ion batteries (NIBs) as a low-cost alternative technology as compared to LIBs. Click to enlarge.

New mesoporous crystalline Si exhibits increased rate of H2 production; potential use in Li-ion batteries also

Green Car Congress

The nanosized crystalline primary particles and high surface areas enable an increased rate of photocatalytic hydrogen production from water and extended working life. These advantages also make the mesoporous silicon a potential candidate for other applications, such as optoelectronics, drug delivery systems and even lithium-ion batteries.
