    a few tidbits

    Fast developing supercapacitor technology may make batteries last longer in consumer gear as well as hybrid buses.

    Solid state batteries are finally seeing real revenues in some specialty niches, but scaling the technology to more demanding mainstream applications will still require significant investment. Battery makers are starting to look at silicon electrodes to improve workhorse lithium-based battery technology. But the technology most likely to significantly impact energy storage markets in the near term is supercapacitors, where there are plenty of opportunities for better processes and materials.

    “Supercapacitors are now at the tipping point,” says Peter Harrop, chairman of IDTechEx. “They may be a way to leapfrog battery technology.” He notes that it is already a real market, revenues are growing at 30 percent a year, and technology is improving rapidly.

    Main markets so far are to supplement batteries when extra power is needed, to make the batteries last longer, or for short-term backup when other power fails. Electric or hybrid buses use them for extra power to go up hills, and for the instant starts in “stop-start” technology to make the batteries last longer. Buses also use them to open the doors in an emergency if the power fails. Trucks use them for sure starting in cold weather. Wind turbines use them to set the blades to protect from damage in big winds if the power fails. Mobile phones will use them for more powerful flash for lighting at greater distance, or for supplementing demands for power for wi-fi, to save the battery or allow use of a smaller one or cheaper one.
