16.1 Introduction

Environmental protection and new energy development have recently become growing industries, in which energy-storage devices are highlighted as crucial components. The electrochemical or double-layer capacitors constitute an important transient-energy-storage technology for rapid-charge/discharge applications. Electrochemical capacitors (double-layer capacitors [EDLC] and pseudo-capacitors) are intrinsically high-power devices (between 5 and 15 kW/kg) of limited energy-storage capability and long cycle life. Compared with batteries, supercapacitors have higher power density with shorter charge/discharge time, longer shelf and cycle life, ...
