Provided herein are inter alia novel compositions and methods having application in the field of enhanced oil recovery. In particular, the large hydrophobe compounds and mixtures thereof presented herein can be used, inter alia, for the recovery of a large range of crude oil compositions from challenging reservoirs.

Disclosed is a method of rearrangement of the molecular structure of isomers of TEXANOL, characterized in that two isomers in TEXANOL is subjected to rearrangement of the molecular structure at a certain temperature and pressure, and 2,2,4-trimethyl-1,3-pentanediol-3-isobutyrate and 2,2,4-trimethyl-1,3-pentanediol-1-isobutyrate in TEXANOL following the rearrangement are in a mass ratio of 31.81-38.65:60.80-67.65. The process of the present invention is simple, no catalyst and other aids are required, and the content of the primary ester in TEXANOL can be significantly increased, so as to improve the volatilization rate of TEXANOL in a paint film, thereby reducing the drying time of the paint film and increasing the number of scrubbing of the paint film, such that the construction conditions of aqueous acrylic paints for exterior walls become relaxed, and the occurrence of floating, whitening, efflorescence, and cracking of the paint film due to water absorption by the non-dried or partly dried paint film during moist or rainy periods is avoided.

A lithium-ion battery with high safety is provided. A lithium-ion battery 20 includes an electrode group 6, an electrolyte, and a battery container 5 that contains the electrode group 6 and the electrolyte. The electrode group 6 is formed by stacking a positive electrode and a negative electrode via a separator. The positive electrode contains a composite oxide of lithium, nickel, manganese, and cobalt as a main positive active material. The negative electrode contains amorphous carbon as a main negative active material. The lithium-ion battery 20 has a discharge capacity of 20 Ah or more. The ratio (the value of Y/X) of a volume Y occupied by the electrolyte to a volume X of a void space in the battery container 5 is 0.65 or more.
