“…3,5,8 As for battery technology, LICs commonly use graphite-based materials, although mostly turbostratically disordered carbon ("hard carbon"), 11 or more rarely lithium titanate, Li 4 Ti 5 O 12 3 at the negative electrode. JSR Micro Co pioneered the industrial development of LIC, 12,13 with hybrid capacitors and prismatic modules with operating voltages of 15.2 V for a capacity of up to 800 F (ULTIMO, 168 × 127 × 112 mm 3 ), showing excellent discharge currents and long cycle life. Asymmetric or serial hybridization can only increase the capacity of common SCs by a factor two since their total capacity is still limited by the capacity resulting from the electric double layer.…”

Understanding the degradation pathways of electrode materials is a key to develop more reliable Li-ion technologies along with an increased energy density and power rate. This study aims to demonstrate the benefits of the combined use of X-ray based characterization techniques and electrochemical assessment for thorough multi-scale anlaysis to elucidate the aging mechanisms of a Li4Ti5O12/AC//LiMn2O4/AC parallel hybrid lithium-ion supercapacitor. Analyses performed on samples extracted from full stack representative of industrial battery application, show that irreversible modifications are observed at all length scales on both electrodes. At the negative electrode, the disaggregation and corrosion of the LTO active material, as well as AC particle cracking and electrode film delamination have been observed. In the meantime, drastic cracking of the AC and LMO active material along with important micro-strain increase at the crystallite level for LMO as well as Mn3+ dissolution are reported at the positive. The formation of a cathode electrolyte interface is also reported. These structural and chemical changes have been identified as precursors to important polarization increase, Li inventory loss and furthermore capacity fading leading thus to device failure.

Comprehensive Study on Dynamic Parameters of Symmetric and Asymmetric Ultracapacitors

et al. 2019

Electrical storage components such as ultracapacitors (UC) have received significant attention from various industrial sectors, from electric vehicles to renewable power plants. This article presents the investigations on dynamic properties of asymmetric Li-ion hybrid (CPQ2300S: 2300 F, 2.2-3.8 V, JSR Co., Tokyo, Japan) and symmetric double-layer (BCAP3400: 3400 F, 2.85 V, Maxwell Technologies Co., San Diego, CA, USA) ultracapacitors. The internal resistance and capacitance of both UCs were slightly changed with respect to current and voltage alterations, but these changes were more prominent for the Li-ion UC. The internal resistance of the Li-ion UC became five times larger and its capacitance decreased significantly when the temperature decreased from +25 • C to −20 • C. More importantly, the double-layer UC exhibited nearly constant capacitance for a wide range of temperature changes (0 • C to −40 • C), although internal resistance increased somewhat. Electrochemical impedance spectroscopy analysis of both UCs was performed for the frequency range of 1 Hz-1 kHz and in the temperature range from −15 • C to +30 • C. It was observed that the temperature effects were much more pronounced for the asymmetric Li-ion UC than that of the symmetric double-layer UC. This work also proposes an improved equivalent circuit model based on an infinite number of resistance-capacitance (r-C) chains. The characteristic behavior of symmetric UCs can be explained precisely by the proposed model. This model is also applicable to asymmetric UCs, but with less precision. similar asymmetric UCs are also applicable to pulsed electric power sources [12,13]. Piórkowski et al. presented a case study about the application of UCs in hybrid systems including an engine start module (ESM), a photovoltaic (PV) module, a battery, and an internal combustion engine (ICE) [14]. In continuation, the hybrid model control strategy was proposed for a double active bridge-based supercapacitor energy storage system [15]. More importantly, the service lifetime of UCs is three times higher compared to electrochemical storage batteries (e.g., Li-ion or lead-acid) although UCs are relatively bulky and voluminous [16]. Consequently, there is a lack of accurate information regarding the ability of Li-ion UCs to provide voltage and current during charge-discharge cycles. Previously, a significant number of experimental investigations were carried out [16][17][18][19][20][21][22] in order to understand the characteristic behavior of UCs. Different direct measurement methods for the evaluation of UC parameters were also proposed [16][17][18][19][20]. A comprehensive review of characterization methods for supercapacitor modeling and general parameter identification techniques were also discussed [21,22].A significant amount of effort has been made to describe dynamic UC behavior using different types of equivalent circuits [23][24][25][26][27][28][29][30]. Some works presented modeling approaches based on electrochemical explanations of UC performance [31][32][33...
