LiB production: mixers for laboratory and Gigafactory
Customized particle design as the key to success
n the production of li-ion batteries, Eirich
intensive mixers are convincing all along
the line: from the functionalization of active
material particles to the production of
coating compounds for separators as well
as wet to dry electrode mixtures. The adaptation
of operating parameters and mode
of operation alone enables users to fulfill
a wide variety of tasks with a single mixer
type.
Particle coating, a central basic operation
in LiB production
I
Coating of particle systems and suspending
for the production of wet electrode
mixtures are central basic operations of LiB
production. Eirich intensive mixers in their
design as Eirich MixSolverÒ with a horizontally
arranged mixing vessel are ideally suited
for suspending, but as mixers with an
inclined mixing vessel they are equally well
suited for coating, but above all granulating
particle systems.
Coating and thus functionalizing active
material particles with different nanostructured
particles such as aerosils or
conductive carbon blacks is a common intermediate
step in the production or use of
active materials. If these processes are to
be carried out completely dry, without the
detour via suspensions and spraying processes,
mixers are needed that generate
high shear rates in the powder bulk. The microgranulation
die patented by Eirich also
shows excellent performance in this task.
The optimized shear field at the outer edges
of the die breaks up the agglomerated
nanoparticles so well at the appropriately
selected die speed that they can dock onto
the surface of the active material particles
and coat them in the best possible way
within a very short time.
Macroscopically, this change at the particle
surface is expressed by a noticeable
change in the bulk density and tamped
density, but also in the flow properties of
the bulk. Depending on the selected mold
speed and mixing time, particle systems
can be designed in a simple way.
Perspectives for the LiB production of
tomorrow
Eirich mixers for coating with aerosols
have been in use in production for many
years with throughputs of several tons per
hour. Active materials coated with conducSimple
scale-up from laboratory to
gigafoctory, e.g. from the universal
1l laboratory mixer EL1 to the 900l
intensive mixer RV16 or MixSolverÒ
RV12 for large-scale production.
tive carbon black form the basis for dry
electrode manufacturing (DBE), which is
currently under development and eliminates
the energy-intensive coating and drying
process. The first pilot and production
plants based on this concept using Eirich
mixers are already being planned.
In summary, Eirich technology offers a
wide range of possibilities with regard to
the production of all kind of energy storage
devices.

Jenike & Johanson is passionate about Bulk Solids
Handling. Why? Because particles matter!
P
articles - regardless of their
size - play an important
role in the efficiency and safety
of plant operations. Jenike &
Johanson is the world's leading
technology company for bulk
material handling, processing,
and storage. Their skilled,
highly technical team of experts
and their industry-leading innovations
have successfully delivered
bulk material engineering
solutions for over 55 years, increasing the safety and productivity of
manufacturing plants across many industries.
Bulk materials and their flow properties are at the core of
Jenike's work. Every one of their projects is truly unique, and their
solutions are highly customized. Clients are offered maximum flexibility
in selecting services required to meet their bulk material
handling needs. The company does not follow the " one size fits all "
concept, as this can be a dangerous pitfall in engineering. Decisions
made during the feasibility and engineering stages of a project are
critically important for its success. If bulk solids systems are not engineered
from the outset to handle the unique characteristics of the
materials in use, process start-up time can be significantly delayed,
and design capacity may never be reached. Jenike & Johanson is the
58
trusted advisor for solving and preventing those issues.
Their services include:
* Bulk Material Testing for All Types of Powders & Bulk Solids
* Conceptual & Functional Engineering of Bulk Handling
Equipment
* Structural Engineering of Bulk Material Silos and Structures
* Custom Equipment Design and
Supply
Jenike & Johanson has developed
proven and practical ways to design
powder and bulk solids storage, handling,
and conveying equipment to
promote reliable, uniform, and unrestricted
bulk material flow. They have
worked on more than 7,500 projects
and tested over 15,000 unique powders
and bulk solids. The unique combination
of science, engineering, and
design capabilities and an engineering
team with nearly 1,000 combined
years of hands-on experience is unmatched
by any other bulk material
handling organization.
