|Abstract||By 2020, transportation is expected to be the second largest source of greenhouse gas emissions; a trend that has been on the rise since 2005.
To reduce or eliminate emissions, replacing diesel locomotives with zero-emission battery- electric switcher locomotives for railroad applications must be considered a necessary option.
The potential use of a proposed hybrid battery, combining an asymmetric supercapacitor and lead-acid battery in battery-electric switcher locomotives, will allow the energy wasted during braking to be recovered and reused for locomotive acceleration.
The development of advanced electrodes of asymmetric supercapacitor and negative electrode lead-acid batteries and their optimal integration in a hybrid battery cell allows us to obtain its advanced performance.
The developed and fabricated hybrid battery (2V) cell prototype with a graded negative electrode demonstrates more than twice the capacity and a longer cycle life compared to conventional lead-acid batteries at high charge/discharge rates.|
