Question 1

Accepted Answer

Conductive carbon plus some binders

Question 2

Accepted Answer

Conductive carbon: SP, CNT; binder: PVDF-5130

Question 3

Accepted Answer

When preparing carbon-coated aluminum foil, the conductive additive is always prepared as a water-based slurry for coating.

Question 4

Accepted Answer

KS-6 itself is a conductive agent and is generally not used as a negative electrode active material. If it were to be used as a negative electrode active material, it should not be necessary to add Super P.

Question 5

Accepted Answer

Graphite used as the anode does need a bit of conductive additive, for example Super P

Question 6

Accepted Answer

Super P Li is not Super C45 carbon black. Although both belong to conductive carbon black, there are obvious differences in physical properties, structural types and application fields. Super P Li has a higher specific surface area and a more complex branched structure, which is more suitable for lithium-ion batteries, while Super C45 has a wider range of applications, but its conductivity is relatively weak.

Question 7

Accepted Answer

Conductive carbon black (Super C65) is more recommended because it has better conductivity and a wide range of applications in high nickel ternary materials (such as NCM811), and is more suitable for the study of cathode material modification of button batteries. This is a reasonable inference based on its advantages in improving electronic conductivity.

Question 8

Accepted Answer

The C45 and C65 in the suffix of the conductive carbon black refer to the average particle size of the primary particles of the material, in nanometers. C45 represents an average particle diameter of about 45nm, and C65 represents about 65nm. This value affects the specific surface area, conductivity and dispersion difficulty of the material. This conclusion is based on industry practice and reasonable extrapolation from the description of the relationship between particle size and performance of conductive carbon black.

Question 9

Accepted Answer

We haven't measured this data; the customer needs to test it themselves.

Question 10

Accepted Answer

None

Question 11

Accepted Answer

Graphite:SBR:CMC:Super P = 94:2.5:1.5:2

Question 12

Accepted Answer

Silicon oxide (1400) and silicon oxide (1600): both of these materials have a carbon coating

Question 13

Accepted Answer

We apologize, but this is the core technology of TuTan Materials’ enterprise; the technical department does not disclose it externally.

Question 14

Accepted Answer

Dissolve the CMC first, then add the conductive agent graphite; after dispersing well, add the SBR last (we introduced this in the article on anode stirring on our public account)

Question 15

Accepted Answer

The specific particle size distribution data of Ketjen Black (KB) is not provided in the knowledge base, but it can be inferred that its particle size belongs to the nanometer range. If accurate particle size distribution information is required, the actual test should be carried out by laser particle sizer.

Question 16

Accepted Answer

Compared with polycrystalline cathode materials, single-crystal cathodes have somewhat poorer conductivity; you need to increase the conductive additive content based on their standard formulation. Alternatively, if you do not want to raise the total conductive additive content, you can replace part of the conductive carbon with CNTs.

Question 17

Accepted Answer

Key factors include: 1) use carbon-coated aluminum foil as current collector; 2) use CNT conductive slurry; 3) nano-sulfur is preferred over sublimed sulfur; 4) optimize slurry formulation; 5) apply light coating; 6) optimize electrolyte amount; 7) ensure correct material selection. Other improvements depend on lab-specific know-how.

Question 18

Accepted Answer

Question 19

Accepted Answer

According to the contents of the knowledge base, the conductive agents commonly used in lithium batteries mainly include the following categories:

1. Carbon black:
-Super P(SP)
-Acetylene Black (AB)
-Ketjen Black (Ketjenblack, KB)-Excellent conductivity, commonly used in lithium iron phosphate systems

2. Carbon Nanotubes (CNT):
-Multi-walled carbon nanotubes (MWCNT)
-Single-walled carbon nanotubes (SWCNT)
-Features: One-dimensional long-range conductivity, low addition (can be less than 0.5%), significantly reduced internal resistance, suitable for high-rate batteries

3. Graphene:
-Two-dimensional lamellar structure with high conductivity and flexibility
-Can be used as an auxiliary conductive agent with SP or CNT to improve the processing performance of the pole piece

These conductive agents can be selected and matched according to different positive and negative electrode material systems (such as LFP, NCM, graphite, etc.) and battery performance requirements (rate, cycle, energy density). Among them, SP and KB are widely used in laboratory and industrial production, while CNT and graphene represent the development direction of high performance.

Question 24

Accepted Answer

According to the knowledge base, conductive carbon black LiTX200, conductive carbon black (Super C65), conductive carbon black (Super C45) and conductive carbon black (Super P Li) are all commonly used conductive agents in lithium ion batteries, but there may be some differences in physical properties, conductive properties and application scenarios. The following analysis is based on the characteristics of conductive agents mentioned in the knowledge base:

1. Conductive carbon black LiTX200:
-There is no specific information about LiTX200 directly mentioned in the knowledge base, but it can be speculated that it may be similar to Super P Li, which is a conductive carbon black used in lithium-ion batteries.
Generally, this type of conductive carbon black has a high specific surface area, which is beneficial to the adsorption of the electrolyte to improve the ionic conductivity, and the primary particles agglomerate to form a branched structure, which can form a chain conductive structure with the active material, which helps to improve the electronic conductivity of the material.

2. Conductive carbon black (Super C65):
-The knowledge base also does not directly mention the information of Super C65, but as a kind of conductive carbon black, its main function is to improve the electronic conductivity of lithium-ion batteries.
-According to the general characteristics of conductive carbon black, Super C65 should also have good electronic conductivity and certain ionic conductivity, suitable for positive and negative materials.

3. Conductive carbon black (Super C45):
-Super C45, as a kind of conductive carbon black, has a similar function to Super P Li, that is, to improve the electronic conductivity of lithium-ion batteries.
-Because different types of conductive carbon black are different in specific surface area, particle size, etc., their performance in practical applications will also be different.

4. Conductive carbon black (Super P Li):
-Super P Li is a conductive carbon black prepared by furnace black method ("MMM" method), which is composed of primary particles with a diameter of about 40nm to form primary aggregates of 150-200nm.
-It has better ionic and electronic conductivity, because carbon black has a larger specific surface area, so it is conducive to the adsorption of electrolytes and improves ionic conductivity.
-In addition, the carbon primary particles agglomerate to form a branched structure, which can form a chain conductive structure with the active material, which helps to improve the electronic conductivity of the material.
-Super P Li powder conductivity of 10~15 S/CM, particle size of 40 ~ 50nm.

In summary, the main difference between these conductive carbon blacks lies in their respective physical properties (such as specific surface area, particle size, etc.) and the resulting difference in conductive properties. The specific type of conductive carbon black selected depends on factors such as battery design requirements, cost considerations, and desired performance indicators. For example, in the application scenario of pursuing higher energy density, conductive carbon black with higher conductive properties may be preferred; while in the case of cost-effectiveness, conductive carbon black with higher cost performance may be selected. However, the specific performance differences need to refer to the technical specifications of each product or through experimental verification to determine.
