New DuraBlue ultracaps from Maxwell increase shock and vibration tolerance, energy and power capacity

Green Car Congress

This enhanced shock and vibration tolerance is particularly important in the transportation market—especially mass transit—and in developing markets in which the road infrastructure might not be quite as smooth as in more developed ones, noted Chad McDonald, director of product marketing. —Chad McDonald.

Sandia researchers developing new family of metal-based ionic liquids for low-cost, efficient flow batteries

Green Car Congress

Sandia researchers have developed a new family of electrochemically reversible, metal-based ionic liquid (MetILs) that could lead to non-aqueous redox (reducing-oxidizing) flow-battery energy storage systems ( earlier post ) able to cost-effectively store three times more energy than today’s batteries.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Smaller Ioxus cells offer a power density of 22-28 kW/kg, and larger cells offer densities of 12-15 kW/kg, said Chad Hall, COO of Ioxus. Energy densities for the cells are typically around 2-4 Wh/kg. Ioxus says that it is working on increasing the energy densities as well. Ioxus makes carbon-carbon ultracapacitors—i.e.,

Ioxus introduces new iCAP ultracapacitor series with a 3,000F cell

Green Car Congress

Rated at 2.7V (2.85V surge), the new iCAP represents the lowest weight, lowest equivalent series resistance (ESR) and highest power density currently available in the market for energy storage cells, the company says. They feature a cycle life of more than 1,000,000 cycles, rated to half rated voltage, 25 °C.
