Super-fast, long-life aqueous rechargeable zinc battery
An international group of researchers has demonstrated an aqueous zinc battery with excellent performance in terms of capacity, rate capability, specific energy, and output voltage. The supercapacitor-battery hybrid device has also shown unprecedented cycling stability 99.2% capacity retention after 17,000 cycles at 100% depth of discharge.
‘The first terawatt of solar PV installed globally took some 70 years to achieve, while the second will likely take only three’
Leading solar researchers from around the world are meeting for the first time in four years in Milan, Italy, for the 8th World Conference on Photovoltaic Energy Conversion (WCPEC-8). The first morning has seen prestigious awards bestowed on two scientific leaders and inspirational discussions as to how the “second terawatt” of solar can be installed globally in just a handful of years.
