UT and ORNL researchers develop new class of pseudocapacitor; anion-based intercalation pseudocapacitance

Green Car Congress

Unlike other devices, the team’s is the first to utilize oxygen anions (negatively-charged ions) instead of cations (positive ions) to store its energy. The device uses a perovskite material (LaMnO 3 ), a structure containing vacant sites where oxygen anions can be stored, making these advancements a possibility.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration. In their proof of concept, the researchers reported that the battery retained 92 percent of its capacity over three months. “We He expects the battery to retain over 80% of its charge in that period.

OSU hybrid “solar battery” uses photo-assisted charging to improve performance of Li-air batteries; “negative overpotential”

Green Car Congress

The basic concept of the integrated solar battery is to use the contribution of the photovoltage to reduce greatly the charging overpotential caused by the difficulty in efficiently electrochemically decomposing lithium peroxide (Li 2 O 2 ), the discharge product formed on the oxygen electrode. Their hybrid design uses only three.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

The concept behind V2G had gained traction in the late 1990s after California’s landmark zero-emission-vehicle (ZEV) mandate went into effect and compelled automakers to commercialize electric cars. And with the revival of the EV, the V2G concept was reborn. The experiment seemed to prove the feasibility of the technology.

Solaris to present new generation hydrogen bus

Green Car Congress

In addition, it will be possible to recharge it by means of a plug-in charging outlet (as is the case in standard electric buses). Hydrogen is stored in composite tanks on the roof; the mass of the tanks will be reduced by about 20% compared to previous models. The battery will be charged with power from the fuel cell.
