Problems solved by technology

In addition, charge accumulation refers to a phenomenon in which the measurement object (for example, an insulator) is charged during the measurement process using electron beams or the like, and appropriate results cannot be obtained.
For example, in measurement using a scanning electron microscope (SEM), when the amount of emitted secondary electrons is larger than the amount of incident electrons, the measurement object may be positively charged during the measurement, and the obtained The SEM image appears white as a whole

Embodiment 1

[0132] To make EMImCl and FeCl which are solid at room temperature 3 EMImCl: FeCl 3 = 1:1 (molar ratio) by weighing, mixing the two in an Ar atmosphere, and melting them uniformly, thus obtaining EMImFeCl as a room temperature molten salt 4 (melting point 18°C). Next, make the EMImCl that is solid at room temperature and the obtained EMImFeCl 4 For EMImCl: EMImFeCl 4 =2:10 (molar ratio) to weigh, and mix the two under the Ar atmosphere, and melt them uniformly, thus obtaining the room temperature molten salt (10EMImFeCl 4 +2EMImCl).

Embodiment 2

[0134] In addition to EMImCl and EMImFeCl 4 The ratio is changed to EMImCl:EMImFeCl 4 =5:10 (molar ratio), operate in the same manner as in Example 1, thereby obtaining a normal temperature molten salt (10EMImFeCl 4 +5EMImCl).

Embodiment 3

[0136] In addition to EMImCl and EMImFeCl 4 The ratio is changed to EMImCl:EMImFeCl 4 =10:10 (molar ratio), operate in the same manner as in Example 1, thereby obtaining normal temperature molten salt (10EMImFeCl 4 +10EMImCl).

Abstract

The invention relates to a normal-temperature molten salt, an electrode, a cell, an agent for preventing charge-up, and a method for observing sample. An object of the present invention is to provide an ambient temperature molten salt having excellent electron conductivity in addition to ion conductivity. The present invention attains the object by providing an ambient temperature molten salt comprising a first imidazolium salt having a cationic segment represented by the general formula (1) and an anionic segment represented by MX 4 (where M is a transition metal and X is a halogen); and a second salt having a cationic segment as a monovalent cation and an anionic segment as a halogen.

Description

technical field [0001] The present invention relates to a normal temperature molten salt having excellent electron conductivity in addition to ion conductivity. Background technique [0002] Molten salt at room temperature is a general term for salts that exist in a liquid state around room temperature (room temperature). As the type of cationic part, imidazoliums, phenazopyridines, alicyclic amines, aliphatic amines, and aliphatic amines are known. Phosphorus etc. In addition, room temperature molten salts are known to be used as electrolytes for electrochemical devices due to their excellent non-volatility and voltage resistance. For example, Patent Document 1 discloses a secondary battery including positive and negative electrodes including a conductive polymer as at least one electrode, and an electrolytic solution composed of a normal temperature molten salt. [0003] In addition, Patent Document 2 discloses an all-solid lithium secondary battery in which 1-ethyl-3-me...
