“…Email: emmanuel.scorsone@cea.fr (Emmanuel Scorsone) Ragone plot relating energy density to power density was calculated from the GCD measurements using the equations from reference [33] and shown in Fig.6c. The data were compared to that of diamond coated silicon nanowire thin films measured in ionic liquid as reported elsewhere [39]. The estimated maximum energy and power densities for PC are 0.17 µWh.cm -2 and 200 µW.cm -2 , respectively.…”

Supercapacitors are promising energy storage devices because of fast charge and discharge capacity, long lifetime and high power sources when compared to conventional batteries. Most carbon based supercapacitors nowadays use organic or ionic liquid based electrolytes in order to benefit from the large potential window in those solvents thus enabling more energy storage. However the devices suffer from low ionic mobility in such electrolytes, and also from economical, safety and environmental concerns associated with the use of organic solvents. Boron doped diamond (BDD) features a wide potential window in aqueous electrolytes and high stability toward oxidation in acidic or alkaline media, and therefore offers the possibility for BDD electrodes supercapacitor to operate in water. Here highly porous diamond electrodes fabricated by microwave plasma chemical vapor deposition of BDD over a conductive polypyrrole template with high double layer capacitance around 3 mF.cm-2 were mounted in symmetrical pouch cell supercapacitor using either 1M H 2 SO 4 or 1M TEABF 4 in propylene carbonate electrolytes. The performances of both devices were investigated. Energy and power values close to 1 µWh.cm-2 and 700 µW.cm-2 were recorded in water, thus surpassing by almost one order of magnitude the energy storage performances of the device using organic electrolyte. Highlights  A symmetrical pouch cell supercapacitor was fabricated using a highly porous diamond electrode material, grown over a polymer template on four inches substrates, and featuring a capacitance of 3 mF.cm-2  The performances of the device were compared when using either an aqueous or organic based electrolytes  Energy and power values close to 1 µWh.cm-2 and 700 µW.cm-2 were recorded in water, thus surpassing by almost one order of magnitude the energy storage performances of similar carbon based devices using organic or ionic liquid electrolytes.

“…The bottom-up overgrowth methods make use of a nanostructured template, over which the diamond is grown. These templates include silicon nanowires ( Gao et al, 2015 ; Gund et al, 2015 ), porous silicon ( Ferreira et al, 2005 ; Silva et al, 2015 ), ‘black’ silicon ( May et al, 2016 ), silica fibers ( Petrák et al, 2017 ; Vlčková Živcová et al, 2018 ), silica nanospheres ( Gao et al, 2014 ), anodized aluminum oxide (AAO) ( Masuda et al, 2001 ; Aramesh et al, 2014 ), and quartz fibers ( Kondo et al, 2009 ). The annealing method applies a high temperature to the diamond in vacuum or an atmosphere of air, pure oxygen, or steam.…”

Diamond Supercapacitors: Towards Durable, Safe, and Biocompatible Aqueous-Based Energy Storage

et al. 2022

Durable and safe energy storage is required for the next generation of miniature bioelectronic devices, in which aqueous electrolytes are preferred due to the advantages in safety, low cost, and high conductivity. While rechargeable aqueous batteries are among the primary choices with relatively low power requirements, their lifetime is generally limited to a few thousand charging/discharging cycles as the electrode material can degrade due to electrochemical reactions. Electrical double layer capacitors (EDLCs) possess increased cycling stability and power density, although with as-yet lower energy density, due to quick electrical adsorption and desorption of ions without involving chemical reactions. However, in aqueous solution, chemical reactions which cause electrode degradation and produce hazardous species can occur when the voltage is increased beyond its operation window to improve the energy density. Diamond is a durable and biocompatible electrode material for supercapacitors, while at the same time provides a larger voltage window in biological environments. For applications requiring higher energy density, diamond-based pseudocapacitors (PCs) have also been developed, which combine EDLCs with fast electrochemical reactions. Here we inspect the properties of diamond-related materials and discuss their advantages and disadvantages when used as EDLC and PC materials. We argue that further optimization of the diamond surface chemistry and morphology, guided by computational modelling of the interface, can lead to supercapacitors with enhanced performance. We envisage that such diamond-based supercapacitors could be used in a wide range of applications and in particular those requiring high performance in biomedical applications.
