Techniques for creating composite organic-inorganic materials by applying optically transparent polymers to the surface of the organic-inorganic perovskite CH3NH3PbI3 and composite cathode materials by modifying the surface of commercial cathode materials of the LiNixCoyAlzO2/LiNixMnyCozO2(NCA/NMC)type with nanoparticles of lithium oxide conductive material Li1.3Al .3Ti1.7(PO4)3 (LATP) have been developed.
It was shown that, depending on the type of polymer, CH3NH3PbI3 perovskite degrades due to the formation of different amounts of additional crystalline phases.It was established that the degree of degradation of the perovskite (1:2) CH3NH3PbI3 film is 100% after 220 days of influence to moisture and oxygen. Under the influence of moisture and oxygen for 500 days, perovskite/polymer films: PVB, SOC, and PVDC degrade only by 1.55%, 1.65% and 3.5%, respectively, which is 65, 60 and 29 times less than for pure perovskite CH3NH3PbI3.
The dependence of the electrochemical characteristics of a layered cathode material containing NCA/NMCon the method for applying a protective layer (mechanical application and sol-gel method) of nanoparticles of the lithium-conducting material LATP with a NASICON structure to its surface has been studied.It was found that for composite cathode materials based on NMC 111, the capacity drop during 80 charge/discharge cycles is reduced by 10–14% compared to the initial NMC 111.
