"Supercabatteries have battery and supercapacitor properties, usually intermediate between the two. While there are lead-acid- and nickel-battery-based versions, the main attention is on ones with a lithium-ion battery electrode and a supercapacitor electrode," Harrop told EE Times .
"These asymmetric electrochemical double layer capacitors (EDLC) are otherwise known as lithium-ion capacitors. They are a promising option for replacing lithium-ion batteries and supercapacitors in automotive applications because they have faster charge and discharge and some other superior properties."
Superabatteries are gaining traction at future-looking automobile makers world wide, according to Harrop, including BMW, Ford, Komatsu and AIST-The Japanese Government Research Center.
Thermoelectrics, which recover energy that would otherwise be lost to heat generation, will also become commonplace in the cars, trucks and convoys of the future, according to Harrop, as well as in many other applications.
"Thermoelectric devices will be a separate market over 1 billion dollars in 2025 including automotive," Harrop told us.
Until now there have been very few themoelectric sucess successs stories except for novelty items. EnOcean Alliance, for instance, uses thermoelectric devices attached to radiators to generate tiny UHF pulses to operate wireless building controls and Schneider Electric uses them to power wireless sensors that trigger responses to heat overloads on copper busbars.
But so far thermoelectrics have been a failure in cars -- for instance, after 20 years of research BMW was only able to achieve about one tenth of the theoretical maximum -- about 3 percent, according to Harrop. But in 2014 the Japanese maker of giant construction vehicles, Komatsu KELK, was able to prove that 1.5KW could be recovered with thermoelectric innovations that doubled their efficiency to 7.5
