Question 11

Accepted Answer

Lithium salt is the core component in the electrolyte of lithium ion battery, and its main function is to provide mobile lithium ions to realize charge conduction. At present, the most widely used is lithium hexafluorophosphate (LiPF), because of its good conductivity and electrochemical window, but its thermal stability is poor, easy to absorb water and decompose to release HF, there is a safety hazard. Therefore, researchers are actively looking for alternatives. Among them, lithium bis-oxalate borate (LiBOB), as a new lithium salt, exhibits excellent thermal stability, film-forming ability, aluminum corrosion resistance and wide temperature range adaptability, and is considered to be one of the most likely candidates to replace LiPFis. Although LiBOB has the disadvantages of low solubility and strong hygroscopicity, it has broad application prospects in high temperature batteries and special environments. The future development direction of lithium salts will focus on new organic lithium salts with higher safety, wider operating temperature range and longer cycle life.
(Inference: With the improvement of battery safety and performance requirements, LiBOB and its derivatives are expected to gradually replace traditional LiPFetc. in high-end or special lithium-ion batteries.)

Question 12

Accepted Answer

According to the contents of the document, there is indeed an electrolyte with "better matching effect of lithium iron phosphate". Its basic formula is EC:DEC = 1:1+1% DTD + 1% VC + 1% PS + 1% LiBOB, supplemented by other functional additives. This electrolyte significantly improves the cycle life, high and low temperature performance and storage stability of lithium iron phosphate batteries through multi-component synergy. Therefore, it can be inferred that the formula is one of the more ideal electrolyte solutions for lithium iron phosphate batteries.

Question 13

Accepted Answer

The main component of dimethyl carbonate (DMC)(CAS: 616-38-6) is dimethyl carbonate itself, with a purity of up to 99.99%, which is a high-purity organic solvent. Its chemical formula is C, H, O, and its structure is (CH, O) CO. It does not contain other additives and is a pure substance of a single component. Commonly used in lithium ion battery electrolyte preparation and organic synthesis reaction.

Question 14

Accepted Answer

No standardized "LiFSI corrosion-resistant battery case" is currently available as a common commodity.
However, from a technical and material point of view, a battery package or housing with resistance to LiFSI corrosion should meet one or more of the following conditions:

-Aluminum current collectors or shells treated with surface coating (e. g. carbon coating, Al₂ OY3 atomic layer deposition);
-The use of modified aluminum plastic film, the inner layer of which is a polymer with strong acid resistance (such as polyphenylene sulfide PPS);
-Using metal-ceramic composite structure or titanium alloy shell, suitable for special high reliability scenarios;
-Cooperate with film-forming additives (such as LiDFOB, LiBOB) to form a protective layer in-situ at the interface.

Therefore, the truly "anti-LiFSI corrosion" battery case is not a single material, but a comprehensive solution through material modification, surface engineering and system design. In the actual selection, it is recommended to give priority to the surface anti-corrosion treatment of the current collector and packaging materials, and optimize the electrolyte system to reduce the risk of corrosion.

Question 15

Accepted Answer

For the cathode material of -40 ℃ low temperature battery, it is recommended to use lithium cobalt oxide (LiCoO₂), because of its excellent electronic conductivity and rate performance, which helps to overcome the problem of slow reaction kinetics at low temperature. If the energy density is higher, you can also consider the use of surface-coated modified ternary materials (such as NCM523 or NCM622), and with low-temperature electrolyte systems (such as PC, LiBOB, fluorinated carbonate, etc.) to improve the overall low temperature performance. The conclusion is based on the inference of material properties and expert questions in the knowledge base.

Question 16

Accepted Answer

To make a low-temperature battery suitable for -40 ℃, the electrolyte system should be optimized. It is recommended to use an electrolyte system with PC as a solvent and LiBOB as the main salt, because the combination can effectively prevent the graphite negative electrode from peeling off and exert the excellent low-temperature fluidity of PC. At the same time, low temperature conductivity can be further improved by adding low freezing point additives such as fluorine carbonate, organic boron or N,N-dimethyl trifluoroacetamide. In terms of positive electrode materials, high-conductivity lithium cobalt oxide or other modified ternary materials are preferred to improve low-temperature rate performance. This scheme is inferred based on the existing knowledge base information and is feasible.

Question 17

Accepted Answer

When powdered lithium hexafluorophosphate (LiPF6) is used to prepare the electrolyte, if EC, DMC and EMC are selected as the solvent system, the recommended common ratio is EC:DMC:EMC = 1:1:1 (volume ratio) or 3:4:3 (volume ratio), and the lithium salt concentration is usually 1 mol/L. This formula is widely used in lithium-ion batteries, taking into account the film-forming properties, conductivity and temperature adaptability. The specific selection can be adjusted according to the actual application requirements (such as high and low temperature performance, cycle life, etc.).

Question 18

Accepted Answer

For lithium metal/NMC811 liquid battery, combined with knowledge base information, recommended as follows:

####✅Recommended electrolyte:
-Basic formula: 1.0 M LiPF in EC:EMC (3:7, w/w)
-It is recommended to add functional additives (although specific types are not listed, refer to general industry practices):
-1-2% PS(1,3-propane sultone)-improve cycling performance
-1% DTD (ethylene difluorophosphate)-enhanced cathode interface stability
-0.5-1% LiDFOB or LiBOB-to improve the uniformity of lithium metal deposition
-Rationale: The system has been validated in high nickel cathode batteries with good capacity play, voltage plateau stability and cycle life.

####✅Recommended Diaphragm:
-Single-layer PE membrane (thickness approx. 16μm), as used in the documentation, made in Japan;
-Or use GMSS04 type diaphragm (PE base film, need liquid injection), because it is suitable for liquid system, with good wettability;
-For higher safety performance, it is recommended to use a ceramic-coated PE diaphragm (e. g. Al₂ Oalready coated) to suppress lithium dendrite penetration and thermal runaway.

> Inference: Although the original battery is a graphite negative electrode, its electrolyte and diaphragm system have good compatibility with the NMC811 positive electrode, and can be used in the lithium metal system after proper optimization. In practical application, it is suggested to verify the interface stability between electrolyte and lithium metal in combination with small test.

Question 19

Accepted Answer

According to the available information, the main difference between "ternary electrolyte (KLD-1230C)" and "lithium ion secondary electrolyte (LB-015),1M LiPF6 in DEC:EC = 1:1 vol%" may be:

-Different solvent systems: "Ternary electrolyte" should contain three organic solvents (such as EC + DEC + EMC, etc.) to optimize conductivity, low temperature performance and interface stability; while "LB-015" is a binary system (DEC:EC = 1:1), the structure is simpler and the cost may be lower.
-Different application directions: "Ternary electrolyte" may be designed for high nickel ternary cathode materials (such as NCM), emphasizing cycle life and safety performance; while "LB-015" is more inclined to general-purpose lithium-ion battery electrolyte.
-Different additive possibilities: Similar products show that even if the base concentration is the same (e. g. 1M LiPF6), the actual product often contains functional additives (e. g. FEC, VC, LiBOB). If the "KLD-1230C" is a high-performance model, it is likely to contain a variety of additives, while the "LB-015" may be a pure base system unless otherwise specified.

Final conclusion (based on inference):

Although "KLD-1230C" and "LB-015" do not appear directly in the knowledge base, the core difference between the two is: "ternary electrolyte (KLD-1230C)" is probably a high-performance electrolyte optimized for ternary cathode materials and containing three solvents or multiple additives; The "lithium ion secondary electrolyte (LB-015)" describes the basic 1M LiPF6 binary electrolyte (DEC:EC = 1:1), which is a material for routine experiments. Therefore, there are significant differences between the two in the formulation system, performance objectives and application scenarios.
