GM slow to act on recalls, House documents show

FILE - In this April 1, 2014 file photo, General Motors CEO Mary Barra listens as she testifies before the House Energy and Commerce subcommittee on Oversight and Investigation on Capitol Hill in Washington.

That email message was not related to the safety defects and mishandled recall of 2.6 million small cars with a faulty ignition switch that's been linked to 13 deaths and dozens of crashes, which is the subject of the subcommittee investigation.

Documents released by a House subcommittee show that managers and employees at General Motors were often slow to react to safety problems — and that one part of GM often didn’t know what another was doing.

Hyundai researchers report improved Li-sulfur battery performance

Researchers from Hyundai have found that the use of a new sulfone-based electrolyte greatly improved the capacity and reversible capacity retention of a Li-sulfur battery compared to the performance of ether-based electrolytes.

In a paper presented at the SAE 2104 World Congress in Detroit, they reported that use of the sulfone-based electrolyte increased capacity by 52.1% to 715 mAh/g and capacity retention by 63.1% to 72.6%.Lithium-sulfur systems are of great interest as a “beyond Li-ion” solution with increased energy densities that would enable much greater electric vehicle range. The Li/S system has a high theoretical specific energy of 2600 Wh kg-1; however, rapid fading of charge capacity is a well-known issue.
