Cathode-electrolyte interphase in lithium batteries revealed by cryogenic electron microscopy. matte

1 answer:

4 0

Cryo-EM is used to preserve and characterize cycled positive electrodes. Under regular cycling conditions, there isn't an intimate coating layer like CEI.A small electrical short can cause a stable conformal CEI to form in place. The conformal CEI's chemistry is revealed by EELS and cryo-(S)TEM.

It has been assumed that the intimate coating layer generated on the positive electrode, known as cathode electrolyte interphase (CEI), is crucial. However, there are still numerous questions about CEI. This results from the absence of useful instruments to evaluate the chemical and structural characteristics of these delicate interphases at the nanoscale. Here, using cryogenic electron microscopy, we establish a methodology to maintain the natural condition and directly see the interface on the positive electrode.

What is the predicted electron configuration of Helium

Crank

1s²

Explanation:

The predicted electron configuration of Helium 1s².

Helium is an element with atomic number of 2. it is located on the last group on the periodic table.

Electron distribution into the energy levels or sublevels of atoms can be shown using electronic configurations.

Here, the two electrons in Helium fills the first energy level with s-sublevel first.

The maximum number of electrons in the sub-level is 2: this gives the 1s² configuration.

How any moles of H2O will be produced from 12.3 moles of HCL reacting with Ca(OH)2?

stiks02 [169]

Answer:

\large \boxed{\text{12.3 mol HCl}}

Explanation:

We need a balanced chemical equation with moles.

2HCl +Ca(OH)₂ ⟶ CaCl₂ + 2H₂O

n/mol: 12.3

The molar ratio is 2 mol H₂O:2 mol HCl.

$\text{Moles of H$_{2}$O} = \text{12.3 mol HCl} \times \dfrac{\text{2 mol H$_{2}$O}}{\text{2 mol HCl}} = \textbf{12.3 mol HCl}\\\\\text{The reaction produces $\large \boxed{\textbf{12.3 mol HCl}}$}$
