Higher voltages and non-toxic electrolytes: Vinatech has set a standard in the fast moving worlds of ultracapacitors, says John Miller.
With the appearance of the 3.0 V rated Vina Tech Hy‑Cap electric-double-layer capacitor, the 3.0 V cell electrochemical capacitor has now arrived. Aqueous electrolyte electric-double-layer capacitors were first introduced in 1978, the most popular application for them at that time being for 5.5 V CMOS memory backup. To achieve that 5.5 V rating required meant, of course, having at least six cells in series. Nonaqueous electrolyte electric . . .
