Abstract: For manufacturing a Zn-air battery, a semi-liquid hydrogel including a polymer component comprising an irradiation activatable crosslinking initiator, and including an electrolyte component is deposited on a zinc anode. At least parts of the semi-liquid hydrogel are irradiated to activate the irradiation activatable crosslinking initiator for crosslinking the polymer component such as to transform the semi-liquid hydrogel into a drop-free yet sticky hydrogel. An air cathode is stuck to the drop-free yet sticky hydrogel.

Abstract: A computer-implemented method for rendering a chart and a time axis for the chart includes receiving a chart comprising time-series data, the time-series data including a start time input and an end time input, selecting one or more time levels based on the start time input and the end time input and based on a width of a display area for the chart, calculating a tick distribution for the time axis based on the selected time levels, where each time level includes one or more label display rules, determining one or more layers of labels to display on the time axis based on the selected time levels and the label display rules for the selected time levels and rendering the chart and the time axis for display in the display area using the calculated tick distribution for the time axis and including the selected time levels and determined labels.
