In 1994 Frank Lev founded Tavrima Canada to commercialise Russian-made supercapacitors marketed under the trade name ESCap. In this article, Lev shares his experience with successful applications combining supercapacitors with lead-acid batteries giving practical examples and rationale for the sustainability of such integrated systems.
The electric starter, invented by Charles Kettering in 1911, paved the way for the proliferation of lead-acid batteries, owing to their high specific cranking power. But, the batteries were severely taxed at high C-rates and sub-zero temperatures. The development of high-power and voltage . . .
