Potassium ion batteries (KIBs) have emerged as a promising energy storage system, but the stability and high rate capability of their electrode materials, particularly carbon most investigated anode ones, become primary challenge. Here, it is identified that pitch-derived soft carbon, nongraphitic carbonaceous species which paid less attention in battery field, holds special advantage KIB anodes. The structural flexibility makes convenient to tune its crystallization degree, thereby...
Dual modification can effectively stabilize layered structure, improve cycling stability, amend reaction kinetics and facilitate Li<sup>+</sup> transport for the application of high Ni cathodes in EVs.
A crucial challenge for the commercialization of Ni-rich layered cathodes (LiNi0.88Co0.09Al0.03O2) is capacity decay during cycling process, which originates from their interfacial instability and structural degradation. Herein, a one-step, dual-modified strategy put forward to in situ synthesize yttrium (Y)-doped orthophosphate (YPO4)-modified LiNi0.88Co0.09Al0.03O2 cathode material. It confirmed that YPO4 coating layer as good ion conductor can stabilize solid-electrolyte interface, while...
The Ni-rich layered oxides are considered as a candidate of next-generation cathode materials for high energy density lithium-ion batteries; however, the finite cyclic life and poor thermostability impede their practical applications. There is often tradeoff between structure stability capacity because intrinsical instability oxygen framework will lead to structural transformation materials. Because strong binding Te atom O atom, herein new technology surface tellurium (Te) doping in oxide...
Abstract The chemical binding between metal compounds and polysulfides provides a good solution to inhibit shuttle effect in Li‐S batteries. However, the Sabatier principle predicts that overly strong adsorption will commonly hinder conversion of polysulfides, so building synergetic mechanism “strong adsorption” “fast conversion” for is significant strategy. To realize this goal, study, defect‐enriched Co 9 S 8 hollow prisms (DHCPs) as both host catalyst material batteries are designed....
Layered double hydroxides (LDHs) are prospective cathode materials for supercapacitors because of their outstanding theoretical specific capacitance and unique layered structure. However, the finite electroactive sites cation species confine practical application in supercapacitors. In this work, a hollow polyhedral ternary metallic Ni2CoMn1-LDH is prepared using zeolitic imidazolate framework-67 (ZIF-67) as template. It has been found that dodecahedral structure constructed by thin...
The safety issue of lithium batteries based on liquid electrolytes has become the focus attention, especially when are exposed to mechanical, thermal, or electrical abuse conditions. To address this issue, gel polymer (GPEs) have attracted widespread interest due property solid–liquid coexistence with higher ionic conductivity, flexibility, and safety. In work, a poly(vinylidene-fluoride-co-hexafluoropropylene) (PVDF-HFP)/poly(methyl methacrylate) (PMMA) matrix GPE, containing...
Hollow carbon nanospheres (HCNs) have found broad applications in a large variety of application fields. Unfortunately, HCNs are known for their tedious operations and incompetent scalable synthesis those widely adopted nanocasting-based routes. Here, we report facile highly efficient method the creation hollow structures by tuning growth kinetics its polymeric precursor. We identified that controlled polymerization Cu2+-poly(m-phenylenediamine) (Cu-PmPD) could form with modulated inner...
