PEO/LiTFSI system, solvent is NMP, EO:Li controlled at a molar ratio of 10–20, operate in a glovebox, spread the prepared slurry evenly in a mold, air-dry naturally and then peel off. A molar ratio of 20 should form and peel off; other components should be adjusted based on your experimental focus and literature.

Question 28

Accepted Answer

There is no relevant information in the knowledge base to support this operation. It is recommended to further consult relevant experimental methods or professional materials to confirm the feasibility.

Question 29

Accepted Answer

PVA is soluble in water, DMSO, DMF, ethylene glycol, and propylene glycol. PVA is poorly soluble in anhydrous ethanol; at room temperature, adding PVA to anhydrous ethanol will not dissolve the PVA particles no matter how long you stir, and they remain as solid suspensions in the ethanol. Even with increased temperature, the improvement in PVA solubility in anhydrous ethanol is very limited.

Question 30

Accepted Answer

The symbol for "volume ratio" is v/v, which means "volume to volume.
For example, mixing 3 mL EC with 7 mL DMC can be expressed as EC:DMC = 3:7 (v/v).

Question 31

Accepted Answer

The solvent system used in the lithium cobalt oxide electrolyte (KLD-1376) is an ester, specifically a carbonate organic solvent (such as EC, DMC, EMC, etc.), so it can be determined that the electrolyte is an ester-based electrolyte.

Question 32

Accepted Answer

The ternary electrolyte solvent is usually a mixed solvent system consisting of three carbonate solvents, and common combinations include EC (ethylene carbonate)/DEC (diethyl carbonate)/DMC (dimethyl carbonate) or EC (ethylene carbonate)/DMC (dimethyl carbonate)/EMC (methyl ethyl carbonate). This combination can optimize the performance of the electrolyte, such as improved conductivity, enhanced stability, and improved electrochemical performance.

If you need a more specific combination ratio or application scenario, please explain further.

Question 33

Accepted Answer

According to the document, the lipid (ester) electrolyte includes GBL, MF, EC, DMC, DEC, EMC and PC. These are components used as organic solvents in lithium ion battery electrolytes.

Question 34

Accepted Answer

Ultrasonic cleaning with water is not recommended for platinum sheet electrodes. If water must be used for cleaning, high-purity deionized water should be used and dried immediately after cleaning to avoid surface oxidation. It is more recommended to use organic solvents (such as DMC, anhydrous ethanol, etc.) for ultrasonic cleaning.

Question 35

Accepted Answer

Lipid electrolytes containing NaPFthat are typically made from NaPFthat as sodium salt, dissolved in one or more of the following ester solvents:
-Ethylene Carbonate (EC)
-Dimethyl carbonate (DMC)
-Diethyl carbonate (DEC)
-Ethyl methyl carbonate (EMC)
-Propylene carbonate (PC)

This type of electrolyte is commonly used in sodium-ion batteries, and its solvent system is similar to lithium, but sodium salt is used instead of lithium salt. This is a reasonable inference of the sodium-electric system based on existing knowledge.

Question 36

Accepted Answer

The knowledge base does not provide specific measured values for the chromaticity of dimethyl carbonate (DMC). According to the industry's general control standards for electrolyte chromaticity, chromaticity is usually controlled within the 200 chromaticity. If more precise values are required, it is recommended to conduct experimental tests or consult the relevant literature.

Question 37

Accepted Answer

The recommended electrolytes for PMMA-based gel polymer electrolytes are:

👉1.0M LiPFⅨ or LiTFSI is dissolved in mixed solvents such as EC/PC, EC/DMC, EC/EMC, etc., and the volume ratio is usually 3:7 or 1:1.

For example:
-1M LiPF₆ in EC:EMC = 3:7 (vol%)
-1M LiClO₄ in EC:PC = 1:1
-1M LiTFSI in EC:DMC = 1:1

This type of electrolyte has good compatibility with PMMA and can effectively swell to form a gel with high ionic conductivity (up to 10? S/cm), which is suitable for lithium-ion battery systems. This recommendation is based on experimental data and material interaction mechanisms in the literature.

Question 38

Accepted Answer

Not all techniques and materials are suitable for lithium iron phosphate. For example, it is mentioned in the knowledge base that DMC performs poorly in high voltage and high nickel systems, while lithium iron phosphate, although not a high nickel system, may not be suitable for the use of certain solvents or additives in some cases. In order to give a more accurate answer, please further clarify what applies to lithium iron phosphate.

Question 39

Accepted Answer

We have this electrolyte, its product code is: MA-EN-ET-0093.

The product information is as follows:
-Name: Lithium Electrolyte (KLD-LP181)
-Formula: 1.0M LiPF in EC:DMC = 1:1 (vol%) with 2.0% VC
-Specifications: 50g, 100g, 250g, 500g, 1000g
-Inventory: in stock (999)
-Storage conditions: to be stored in a glove box with moisture <5ppm, temperature <24°C

This code corresponds to the exact formula you are querying.

Question 40

Accepted Answer

For lithium manganate (LiMnO2 Oa) cathode material, it is recommended to use an electrolyte composed of lithium hexafluorophosphate (LiPF) as the base lithium salt, ethylene carbonate (EC), dimethyl carbonate (DMC), ethyl methyl carbonate (EMC) and other mixed solvents, such as the basic formula similar to Shanshan Technology LD-124 or LD-1234.
In order to improve the high temperature cycle stability and inhibit the dissolution of manganese, it is recommended to choose the electrolyte containing high temperature stable additives, such as high temperature product LD-134BJ, or add functional additives that can form a stable CEI film. This recommendation is a reasonable inference based on the existing electrolyte system and lithium manganate battery characteristics.

Question 41

Accepted Answer

Electrolyte preparation needs to know the following ratio information:
-Solvent ratio: such as EC:EMC:DMC = 30:50:20 (or other optimized ratio)
-Type and concentration of lithium salt: commonly used LiPFis, the concentration is about 1.0~1.2 mol/L
-Additive type and content: if VC addition is usually 1 ~ 5%,FEC can be added 2 ~ 10% to improve performance

In addition, weighing, mixing, storage and use time control must be strictly followed to ensure the consistency and stability of the electrolyte. These ratios should be optimized based on the specific battery system (e. g. positive and negative materials, operating temperature range).

Question 42

Accepted Answer

Yes, we provide the electrolyte. The product name is "lithium battery electrolyte (KLD-LP02)", the model is MA-EN-ET-0090, and the composition is 1.0M LiPF6 in EC:DMC = 1:1 (vol%) + 2% VC, which is exactly the same as your requirements. Existing 50g to 1000g a variety of specifications, sufficient inventory, can be shipped at any time.

Question 43

Accepted Answer

Yes, solvents EC, EMC, DMC are generally considered hazardous chemicals. They have the characteristics of flammability, sensitivity to moisture, and easy decomposition and gas production at high temperatures. In practical applications, they need to be stored and operated in accordance with hazardous chemicals, especially in closed, dry, and low-temperature environments. This conclusion is inferred based on its physical and chemical properties and general industry specifications.

Question 44

Accepted Answer

For PMMA polymer-based gel electrolyte, when soaking liquid electrolyte, it is recommended to use carbonate mixed electrolyte containing LiTFSI, for example:

-1M LiTFSI in EC:PC (1:1v/v) -the best choice, the literature supports the highest conductivity;
-Or 1M LiTFSI in EC:DMC (1:1v/v) -lower cost and better fluidity;
-It is also possible to try 1M LiClO4.or LiAsF in EC:PC, but the security is slightly lower.

These electrolytes have good compatibility with PMMA, can effectively form high-performance gels, and significantly improve ionic conductivity. Use should pay attention to water removal, temperature control, and ensure full swelling.

Question 45

Accepted Answer

Low-temperature electrolytes are usually systems with dimethyl carbonate (DMC) as the main solvent, which can be combined with other solvents such as EMC as required, and the use of DEC can be avoided or reduced. This type of electrolyte is suitable for applications requiring low temperature discharge or low temperature cycling performance. Whether to add specific additives (such as PS, FEC, etc.) needs to be optimized according to the specific positive and negative materials and working conditions. This conclusion is extrapolated from the discussion of solvent properties in the literature.

Question 46

Accepted Answer

The electrolyte is mainly composed of the following three parts:
1. Electrolyte lithium salt: the most commonly used is lithium hexafluorophosphate (LiPFis), which is used to provide mobile lithium ions;
2. Organic solvents: mostly carbonate compounds, such as ethylene carbonate (EC), dimethyl carbonate (DMC), diethyl carbonate (DEC), ethyl methyl carbonate (EMC), propylene carbonate (PC), etc., play a role in dissolving lithium salts and promoting ion conduction;
3. Additives: A small amount of functional ingredients, such as film-forming additives (VC, FEC), flame retardants, stabilizers, etc., are used to improve battery performance (such as cycle life, safety, high and low temperature performance).

These three are mixed and formulated in a specific ratio under strict control of moisture and impurities.

Question 47

Accepted Answer

The volume ratio is usually expressed as "v/v" in the form "A:B = x:y (v/v)" or written directly as "x:y by volume". In the document, "volume ratio" is described as a common expression of electrolyte formulation in the field of scientific research, for example, the solvent is mixed in equal volume (e. g. EC:DMC = 1:1) and prepared in a volumetric flask. This representation, which emphasizes the proportion of each component to volume, is common in university studies and differs from the mass ratio (w/w) widely used in industry.

Question 48

Accepted Answer

Half-cells are typically liquid. In scientific research and routine testing, half-cells (especially button-type half-cells) generally use liquid electrolytes (such as EC/DMC solutions containing LiPFisn) as ion-conducting media and are used in conjunction with separators. While solid-state electrolytes are being studied, they are not currently standard for half-cells. Thus, unless otherwise specified, the term "half-cell" generally refers to a liquid cell.

Question 49

Accepted Answer

Based on the above analysis, for the "PC ternary" electrolyte, it is usually composed of propylene carbonate (PC) as the main or part of the solvent, with other linear carbonate solvents (such as DMC, EMC), plus lithium hexafluorophosphate (LiPF6) as the electrolyte salt, and some functional additives. However, it should be noted that the specific formula needs to be adjusted according to the design requirements of the battery, especially considering the compatibility between PC and graphite anode. This conclusion is a reasonable inference based on the available information.

Question 50

Accepted Answer

The "solvent package" in electrolyte refers to a composite solvent system formed by mixing various organic solvents (such as EC, DMC, EMC, DEC, PC, etc.) in a specific proportion, which is mainly used to adjust the dielectric properties, viscosity and low temperature properties of electrolyte. "Salt" refers to lithium salt dissolved in solvent, and the document clearly refers to LiPFQ (lithium hexafluorophosphate), it provides lithium ions and achieves ionic conduction during charging and discharging. Therefore, electrolyte = lithium salt (e. g. LiPF) organic solvent package (e. g. EC/DMC/EMC mixture).
