Room-Temperature-Cured Copolymers for Lithium Battery Gel Electrolytes

Polyimide-PEO copolymers with branched rod-coil molecular structures, that can be cured into film form at room temperature, have been invented for use as gel electrolytes for lithium-ion electric- power cells. These copolymers offer an alternative to previously patented branched rod-coil polyimides, and an advantage in room-temperature functionality.

Lithium-Ion Batteries Fuel the Future of Automotive Design

In 1924, General Motors president Alfred P. Sloan Jr. devised annual model-year design changes in order to maintain unit sales. Body shapes faced cosmetic changes every year, whether or not the underlying automobile had changed. This breakthrough strategy had widespread effects on the automobile business, automotive design, and eventually the United States economy. In recent years, amongst a worsening economy and a struggling auto industry, the underlying automobile has changed rapidly, with emphases on efficiency and environmental friendliness.

Utilizing Ocean Thermal Energy in a Submarine Robot

A proposed system would exploit the ocean thermal gradient for recharging the batteries in a battery-powered unmanned underwater vehicle (UUV) of a type that has been deployed in large numbers to research global warming. A UUV of this type travels between the ocean surface and depths, measuring temperature and salinity.
