Batteries have fallen short in comparison to both supercapacitors and hybrid capacitors because of their low power density and limited charge-discharge cycle. Most of the previous research in this field focuses on hybridizing either supercapacitor or hybrid capacitor with the battery but not both.
Abstract: This paper proposes a novel topology of hybridizing battery, supercapacitor and hybrid capacitor for optimum utilization of energy in electric vehicles. Hybridization of energy storage has been the theme of much research in the field of power electronics as it is an effective economic solution towards improving the utilization of energy.
The result are as follows: The charging efficiency is higher when the super-capacitor is charged preferentially. Sequential charging is adopted, with stable current, small fluctuation and better battery protection performance. This study demonstrated the development and prospect of hybrid super-capacitor and lead-acid battery power storage system.
The hybrid device can achieve a specific energy of 36.2 Wh kg −1 at a specific power of 39.1 W kg −1, and even 8.9 Wh kg −1 at 2.38 kW kg −1 (all based on the mass of the cathode active material).
The Ragone Plot further demonstrates the addition of more battery material into the hybrid composite cathode increases energy performance but at the cost of lowering the overall power performance. A specific H-LIBC pouch cell can be designed according to energy density and power density requirements of energy storage device applications [ 20, 21 ].
In recent publications, we have demonstrated a new type of energy storage device, hybrid lithium-ion battery-capacitor (H-LIBC) energy storage device [ 7, 8 ]. The H-LIBC technology integrates two separate energy storage devices into one by combining LIB and LIC cathode materials to form a hybrid composite cathode.
