A hydrogen-like atom/ion (usually called a "hydrogenic atom") is any atomic nucleus bound to one electron and thus is isoelectronic with hydrogen. These atoms or ions can carry the positive charge e ( ...

The zinc-air battery-based hydrogen system uses a high-activity, long-lasting catalyst for three key reactions at low ...

Rechargeable lithium-ion batteries don’t last forever. Over time, they hold onto less charge, eventually transforming from power sources to bricks. One reason: hidden, leaky hydrogen ...

Self-assembling molecules into organized structures is highly valuable for developing new materials. One notable class of ...

Toyota is one of the most noteworthy brands, sitting at the forefront of solid-state battery technology, with plans to ...

Xiaowei Teng, the James H. Manning Professor in Chemical Engineering at WPI, is leading a team to explore new battery ...

while liquid oxygen-liquid hydrogen rocket engines may reach closer to 450 seconds. Electrostatic ion thrusters are almost an order of magnitude better, on the order of 2,000-3,000 seconds ...

What gives them their exciting potential is their ability to take more than 30,000 charge/discharge cycles, and their relative safety when compared to lithium ion cells. Hydrogen in a pressure ...

a PEM hydrogen fuel cell, and a lithium-ion battery. “The fuel cell can only supply power directly to the consumer and it does not charge the battery nor support the electrolyzer,” the ...

In a water molecule, the electrons are shared unevenly between the oxygen end and the two hydrogen ends, creating a partial negative charge on the oxygen end and ... Fluoride (F – ) is the ionic form ...

That system was then compared against an identical system with the addition of a Li-Ion battery ... maximum charge of 22 kW. Through the analysis, the group found that the hybrid PV-hydrogen ...

A WPI research team has improved iron-based alkaline batteries by adding silicate, preventing hydrogen gas formation during ...
