Ness Corp. (Korea) debuted a new line of 2.3V ultracapacitors. These ultracapacitors are specifically designed with portable and handheld devices in mind. For this reason, Ness Corp. claims that they are lighter, smaller and less expensive than regular ultracapacitors to operate. Ness Corp. also claims that the new ultracapacitors charge and discharge more than 100 times faster than batteries.
The new ultracapacitors are manufactured with an activated carbon powder in the electrode coating process, allowing for easier manipulation of the thickness and width of the coated layer. Ness' ultracapacitors range from 10 to 2,500 farads. The 2,500F/2.3V ultracapacitor's energy densities are 2.83W-h/kg and 3.74W-h/l. Its power densities are 5.1kW/kg and 6.7kw/I, with charges and discharges of more than 100,000 cycles.
The new ultracapacitors are available in lots of 100. Prices are $5 per unit for a capacitance of 10F, $15 for a capacitance of 60F, and $230 for a 2,500F.
