DuPont introduces Energain li-ion battery separator; claims it boosts power 30%
Aug 19th
Posted Aug 19th 2010 7:57AM by Eric Loveday Filed under: EV/Plug-in, Hybrid, Green Daily DuPont has just introduced the world’s first nanofiber-based polymeric lithium-ion battery separator that could prove to be a remarkable innovation in the rechargeable automotive battery industry. DuPont claims that its Energain nanofiber separators can increase battery power by 15-30 percent while also lengthening battery life by up to 20 percent. In addition, DuPont’s nanofiber separator is said to improve battery stability at high temperatures, leading to safer operation.
DuPont believes that automakers will utilize the power-boosting Energain technology to extend the range of electric vehicles (EVs) and to provide hybrids with More >

ERIC WESOFF: JULY 28, 2010
How about we start by calling storage, storage and a battery, a battery?
Utility-scale energy storage in the field today is limited to pumped hydro, a few large deployments using compressed air energy storage (CAES), hundreds of megawatts of sodium sulphur (NaS) batteries, mostly in Japan, and some experiments with banks of lithium-ion batteries, nickel-cadmium batteries and regenerative fuel cells (flow batteries). Greentech Media has long covered the energy storage market with technologies that include:
- Batteries (Li-ion, NiMh, Zinc Air, NaS, etc.)
- Flow Batteries
- Flywheels
- Phase-change materials
- Ammonia
- Thermal Storage as heat or ice
- Hydrogen systems
- Compressed Air Energy Storage (CAES)
- Pumped Hydro
- Superconducting Magnetic Energy Storage (SMES)
- Ultracapacitors
- Using off-peak wind energy to synthesize fuels More >

Jun 21st
Lithium-ion batteries with nanotube electrodes could go longer between charges.
MONDAY, JUNE 21, 2010
A lithium-ion battery with a positive electrode made of carbon nanotubes delivers 10 times more power than a conventional battery and can store five times more energy than a conventional ultracapacitor. The nanotube battery technology, developed by researchers at MIT and licensed to an undisclosed battery company, could mean batteries that extend the range of electric vehicles and provide longer periods without recharging for electronic gadgets, including smartphones.
Nano power: The pores between the nanotubes in this transmission- electron microscopy image can store lithium ions in a high-power battery. More > (No Ratings Yet) Loading ...Electric Transmission Texas Brings Large Utility-Scale Battery Online

Electric Transmission Texas, LLC dedicated the nation’s largest, and Texas’ first, utility-scale battery yesterday during ceremonies in Presidio, one of the oldest cities in Texas.
The 4-megawatt NAS sodium-sulfur battery system was energized March 31 to the Electric Reliability Council of Texas grid.
ETT is a joint venture between subsidiaries of American Electric Power and MidAmerican Energy Holdings Co.
The NAS battery system represents part of an approximately $70 million overall commitment by ETT to improve transmission reliability in Presidio and surrounding areas. The dedication ceremonies recognized installation of the new battery system and thanked local and state leaders for the More >
