The main components of lithium batteries & its application

Answer: In order to achieve carbon neutrality and reduce carbon dioxide emissions, Clean Energy is now being vigorously developed and promoted.

Lithium batteries are used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, as well as power tools and electric bicycles. , electric motorcycles, electric vehicles, military equipment, aerospace and other fields. As one of clean energy storage, Lithium batteries play an important role in carbon neutral. Now noticed that there are two fair related with lithium battery in just December #Powtech 2023 German &  #TheBatteryShow America

Generally speaking, the Li battery has The four major material , they are  anode35%  cathode12% electrolyte & separator 12% ,

Anode material concludes Lithium cobalt oxide (LCO), Lithium Iron Phosphate(LFP), Lithium manganese oxide (LMO), Ternary materials: lithium nickel cobalt manganate (NCM) and lithium nickel cobalt aluminate (NCA), etc.

Cathode material concludes: Carbon materials& non-carbon materials

Carbon materials:

Graphite (natural graphite, composite graphite, artificial graphite)

Invisible fixed carbon (hard carbon, soft carbon)

Carbon nanomaterials (graphene)

Non-carbon materials:

Titanium-based materials, Tin-based materials, Silicon-based materials (silicon-carbon composite materials), nitride.

It is important to note that the specific percentages of these materials can vary depending on the battery pack's specific chemistry and design. Besides that, those materials are far more just for batteries. They can be wildly used in other area too.

As one the producing process for Li battery, air grinding equipment & system play an important role, meanwhile, the related material for Li battery like PTFE, PVDF needs air grinding jet mill & system on production too.

China's new energy industries such as the lithium battery cathode and cathode material industry and the photovoltaic material industry are growing rapidly. As the supplier of Air grinding equipment, we jump in the river production process. For years study & development, we make big progress & successfully provide our service to companies like ShanShan Corporation, ALBEMABLE Jiangxi, BTR New material group Co., Ltd.  Also hope we can recognize by customer globally & play an important role in this new field

What can air grinding equipment do during the Lithium battery product process

Answer: As the raw materials for lithium batteries, the production of for it is inseparable from crushing and grading equipment. They needs to be crushed to sufficient fineness (about 1 to 30μm, according to customer’s needs) and the fine powders of different fineness are classified for efficient utilization. That will help high-quality production of lithium-ion batteries. The advantages of the fluidized bed jet mill are mainly reflected in the good dispersion effect, the particle size can be adjusted by grinding wheel, and the wear and energy consumption are relatively small, so it is more suitable for application in lab used & large-scale industrial production. 

Meanwhile, According to Lithium battery materials’ properties, it needs contamination-free treatment & controls the iron content to make sure the materials purity.  Ceramic, enamel, Silicon nitride, anti-wear PU or thermal spraying, those protections way can be recommend. Classifying wheel, the feeder, inside cyclone separator, fluidized bed chamber, dust collector need protection too.  Different materials would choose specific protection material, which can be adjusted according to customers needs.
