An effectively inhibiting lithium dendrite growth in-situ-polymerized gel polymer electrolyte

In situpolymerization process: an essential design tool for lithium polymer batteries

“…One report in which the direct deposition approach employed for the in situ processing of LMPB cells by Niu et al uses a mono-functional monomer called ethylene glycol phenyl ether acrylate (EGPEA). 364 This work is important as it overrules the two conventional school of thoughts existing in the LB community based on the existing literature reports such as (i) acrylate/methacrylate monomers are not suitable for LMPBs, and (ii) cross-linked PEs are indeed necessary against HSAL growth, by convincingly proving that Li-metal compatible acrylate monomer-derived non-cross-linked homo-polymer hosts with high mechanical stability are also suitable for LMPBs. Interestingly, the non-cross-linked homo-polymer-based GPE derived from EGPEA exhibits good mechanical strength, which could be due to the bulky phenyl group present in the monomer structure.…”

Chemical vapor deposition growth of carbon nanotube confined nickel sulfides from porous electrospun carbon nanofibers and their superior lithium storage properties

“…In the S 2p region, the peaks at 161.6 and 162.5 eV are assigned to the S 2p 3/2 and S 2p 1/2 orbitals associated with Ni-S bonding. 35,36 Besides, the main peaks at 163.9 and 165.1 eV can be attributed to the C-S bonds while the peak at 166.4 eV is ascribed to the oxidation of sulfur outside the surface. 13,35 Time-dependent experiments were also performed in order to understand the structural evolution during the CVD reaction.…”

Building Better Batteries in the Solid State: A Review

“…Moreover, as some of the polymers now display an electrochemical window that reaches 5 V, it is possible to switch from LiFePO 4 to other inorganic cathodes with larger redox potentials relative to Li + /Li. In particular, in situ polymerized poly(ethylene glycol phenyl ether-acrylate) (PEGPEA)-based GPE combined with 1 mol L −1 LiPF 6 in EC//DMC/ethyl methyl carbonate (EMC; 1:1:1 in volume) solvent was introduced by Niu et al [315]. This GPE displayed a conductivity of 3.35 10 −3 S cm −1 at 25 °C and an electrochemical stability up to 4.9 V vs. Li + /Li.…”
