THE CAYMAN ISLANDS STORY: HOW ONE OF THE WORLD'S LEADING OFFSHORE CENTERS STRUCK THE BALANCE BETWEEN REGULATION AND COMMERCIAL SUCCESS TO MAINTAIN ITS COMPETITIVE EDGE Paul Byles This paper provides an overview of the development of the Cayman Islands as an international financial services centre. It looks at the main types of offshore financial services, the international challenges that the Cayman Islands faced and how the country dealt with these. The paper ends with some conclusions as to the key success factors for the Cayman Islands which can be drawn on to better understand what is required for a typical offshore centre to succeed in a changing global landscape.

<P><B>Abstract</B></P> <P>There is a growing interest to hybrid energy storage devices, such as lithium-ion capacitors, in which battery-type electrodes are combined with capacitor-type ones. It is anticipated that the energy density (either gravimetric or volumetric) of lithium-ion capacitors is improved if pseudocapacitive or fast insertion materials are used instead of conventional activated carbon (AC) in the capacitor-type electrode. MXenes, a new family of two-dimensional transition metal carbides, demonstrate metallic conductivity and fast charge-discharge behavior that make them suitable for this application. In this study, we move beyond single electrodes, half-cell studies and demonstrate three types of hybrid cells using Nb<SUB>2</SUB>CT<SUB>x</SUB>–carbon nanotube (CNT) films. It is shown that lithiated graphite/Nb<SUB>2</SUB>CT<SUB>x</SUB>-CNT, Nb<SUB>2</SUB>CT<SUB>x</SUB>-CNT/LiFePO<SUB>4</SUB> and lithiated Nb<SUB>2</SUB>CT<SUB>x</SUB>-CNT/Nb<SUB>2</SUB>CT<SUB>x</SUB>-CNT cells are all able to operate within 3 V voltage windows and deliver capacities of 43, 24 and 36 mAh/g (per total weight of two electrodes), respectively. Moreover, the polarity of the electrodes can be reversed in the symmetric Nb<SUB>2</SUB>CT<SUB>x</SUB>-CNT cells from providing a positive potential between 0 and 3 V to a negative one from −3 to 0 V. It is shown that the volumetric energy density (50–70 Wh/L) of our first-generation devices with MXene electrodes exceeds that of a lithium titanate/AC capacitor.</P> <P><B>Highlights</B></P> <P> <UL> <LI> 3 types of lithium-ion capacitors using Nb<SUB>2</SUB>CT<SUB>x</SUB>-CNT as one electrode were tested. </LI> <LI> The highest volumetric energy density of 50–70 Wh/L was achieved. </LI> <LI> Energy density of symmetric cell exceeds that of lithium titanate/activated carbon. </LI> <LI> The lithiated graphite/Nb<SUB>2</SUB>CT<SUB>x</SUB>-CNT shows the highest gravimetric performance. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
