Phytic Acid Assisted Fabrication of High Specific Surface Area Carbon-Wrapped Ni2P4O12 Nanoparticle Electrodes for Lithium-Ion Battery

“…According to Table S1 and Figure c (gray ellipse marking), the electrode materials obtained from inorganic phosphoric acid contained higher levels of oxygen, while those prepared from organic phytic acid as the phosphorus source showed higher carbon content due to the fact that the organic phytic acid contains six-carbon rings, which can be converted into amorphous carbons mainly made up of pseudographite layers and disordered regions, possessing excellent lithium-ion storage active sites, which will further boost the materials’ stability. The C 1s spectrum in Figure d showed three fitted subpeaks at 284.7, 285.5, and 288.9 eV associated with C–C/CC, C–O, and CO, respectively. , Remarkably, the low amount of carbon in NPO-HP (7.6%, Table S1) was mainly introduced by the XPS test that required elemental C for the charge correction or formed by the carbon in the air that was involved in the reaction during the evaporation in the oil bath. The peak intensity of the residual oxygen-containing group (C–O) in the NPO-HP samples was noticeably higher, which may be attributed to the inadequate thermal decomposition of the introduced airborne carbon.…”

Recent Advances in Hybrid Lithium-Ion Capacitors: Materials and Processes

“…As an important component of LICs, electrode materials exert a profound influence on the performance of LICs. ,− Currently, anode materials for LICs can be categorized into three groups based on lithium storage mechanisms: insertion-type materials − (e.g., various carbonaceous materials, TiO 2 , V 2 O 3 , Li 4 Ti 5 O 12 ), alloy-type materials , (e.g., Si, Sn, Ge), and conversion-type materials − (e.g., transition metal oxides, chalcogenides). Among these, insertion-type materials have attracted significant attention due to their superior Li + transport properties and stable structure.…”

Extrinsic pseudocapacitive ultrathin 2D MoS2 nanoflakes clamped on 1D Sb2S3 nanorods: an advanced heterostructured anode for high-energy ammonium ion hybrid capacitors

“…31,32 Considering these issues, redoxactive anode materials that can simultaneously provide high capacitance and stability at negative operating potentials are needed. [31][32][33][34] Of the many potential candidates, extrinsic pseudocapacitive metal suldes are promising for aqueous ion capacitors because of their exceptional electrochemical properties and structural diversities. 33,35,36 Specically, because of its structural stability, Sb 2 S 3 was investigated for electrocatalysis, battery and photovoltaic device applications.…”
