“…The industrial application demands more energy and power density from the battery as well as safety concerns. [1][2][3] From the viewpoint of preventing internal short-circuit failure in a lithium-ion battery, a separator is considered a critical component to secure battery safety, because its primary function is to maintain physical separation between the cathode and anode of the battery. [4][5][6] Currently widespread separators in lithium-ion batteries are typically made of polyolefins, predominantly polyethylene (PE) or polypropylene (PP).…”

Polyimide (PI) / Polyethylene terephthalate (PET) composite membranes are prepared by the phase inversion process from casting solutions composed of PI, N-methyl-2-pyrrolidone (NMP) and PEG. The porosity, liquid electrolyte uptake and room temperature ionic conductivity are investigated. The experiments demonstrate that the average pore size of the membranes increase with increasing the weight ratio of PEG. At the same time, it leads to the increase of the porosity, liquid electrolyte uptake and room ionic conductivity. The PI microporous membrane shows only about 4% of thermal shrinkage in at 180 • C under air atmosphere. The cell with the PI/PET composite membrane shows stable cycling performances through the charge-discharge tests with capacity retention ratios of 86.7% covering 50 cycles. The cell with the PI/PET composite membrane shows better rate capabilities than the cell with Celgard one under 10 C-rate.

“…The selection of electrochemical polymerization additives, on the other hand, allows the polymer monomer to be electrochemically polymerized on the cathode surface or the separator, forming a conductive polymer film, causing an internal short circuit to protect the cell. 114–119 The ideal additive should be set to polymerize between the range higher than the charge-cut-off potential and below the overcharge protection voltage. Currently, additives that can be electrochemically polymerized are mainly benzene-based (biphenyl, cyclohexyl benzene), 120 pyrrole-based (pyrrole, N -methylpyrrole), 121 thiophene-based (thiophene, 3-chlorothiophene) compounds.…”

“…A variety of phosphides have been confirmed useful as flame-retardant solvents or additives to improve the safety of batteries. Also, some of them such as (phenoxy)pentafluorocyclotriphosphazene N 3 P 3 (OPh)F 5 (PFPN), , N -(triphenylphosphoranylidene) aniline (TPPA), tri(β-chloromethyl) phosphate (TCEP), and poly[bis(ethoxyethoxyethoxy)phosphazene] (EEEP) have been reported as electrolyte additives to improve the performances of HVLCO. Xia et.al found that an addition of only 5% PFPN can make the electrolyte thoroughly nonflammable, as shown in Figure a.…”

The combination of high voltage cathode and metal or graphite anodes provides a feasible way for future high-energy batteries. Among various battery cathodes, lithium cobalt oxide is outstanding for its excellent cycling performance, high specific capacity, and high working voltage and has achieved great success in the field of consumer electronics in the past decades. Recently, demands for smarter, lighter, and longer standby-time electronic devices have pushed lithium cobalt oxide-based batteries to their limits. To obtain high voltage batteries, various methods have been adopted to lift the cutoff voltage of the batteries above 4.45 V (vs Li/Li+). This review summarizes the mechanism of capacity decay of lithium cobalt oxide during cycling. Various modifications to achieve high voltage lithium cobalt oxide, including coating and doping, are also presented. We also extend the discussion of popular modification methods for electrolytes including electrolyte additives, quasi-solid electrolytes, and electrode/electrolyte interfaces.
