NOVELTY - Nanoparticle organic hybrid material (NOHM (I)), comprises an organic polymeric corona having a molecular weight of 100-50000 g/mol, where the organic polymeric corona is attached to an inorganic nanoparticle core, and where the NOHM: exhibits liquid-like properties so that the NOHM (I) moves freely and flows in a manner so that when the NOHM is in a container the NOHM (I) takes the shape of the container; and has a volume fraction (fc) of the inorganic particle of 0.05-0.75.    USE - The nanoparticle organic hybrid materials are useful in compositions, lubricants, electrolyte which is useful in rechargeable battery (all claimed), personal care products (e.g. sunscreens), adhesives formulations, ferrofluids, paints, coatings, lithium-ion battery electrodes, electrolytes for rechargeable batteries, electrolytes for fuel cells, shear-thickening coatings and adhesive formulations.    ADVANTAGE - The nanoparticle organic hybrid materials: forms a stable self-suspended suspension; exhibits liquid-like properties so that the NOHM (I) moves freely and flows in a manner so that when the NOHM is in a container the NOHM (I) takes the shape of the container; and facilitates high temperature operations without the need for expensive packaging/sealing. The nanoparticle organic hybrid materials exhibits: excellent stability against aggregation and exhibit rheological features characteristic of a soft-glassy solid; high mechanical modulus; hardness; lithium intercalation efficiency; high refractive index; large heat capacity; and high electrical/thermal conductivity.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a composition comprising the NOHMs;    (2) an electrolyte, comprising the NOHM (I) and an ionic dopant;    (3) a rechargeable battery, comprising: the electrolyte; a lithium metal anode and a cathode;    (4) a lubricant comprising the NOHM (I) and a dispersion;    (5) a composition comprising the first NOHM (I) and a second NOHM (II) having a different organic polymeric coronas or inorganic nanoparticle core than the first NOHM (I);    (6) a NOHM, comprising a first organic polymeric corona having a molecular weight of 100-50000 g/mol attached to an inorganic nanoparticle core and a second organic polymeric corona having a molecular weight of 100-50000 g/mol attached to the inorganic nanoparticle core, where the second organic polymeric is composed of a different polymer from that of first organic polymeric corona, the NOHM exhibits liquid-like properties so that the NOHM moves freely and flows in a manner so that when the NOHM is in a container the NOHM takes the shape of the container, and the NOHM has a volume fraction (fc) of the inorganic particle of 0.05-0.75; and    (7) producing the NOHM, comprising covalently attaching an organic polymeric corona having a molecular weight of 100-50000 g/mol to an inorganic polymeric corona.
