Chemical Substances Suitable for Battery R&D

In the rapidly evolving field of battery technology, combinations of chemical substances play a pivotal role, providing robust support for the exploration and development of new battery technologies. By optimizing various performance aspects of lithium-ion batteries, such as safety, energy efficiency, environmental friendliness, and reducing reliance on scarce metals, they drive innovations in lithium-ion battery technology. For instance, we have meticulously crafted a series of synthetic modules to assist you in making breakthroughs in cutting-edge fields like organic batteries and solid-state batteries, exploring the boundless possibilities of future battery technologies.

In addition to the conventional and alternative materials widely used in primary battery components (such as anodes, cathodes, and electrolytes), we also offer key materials commonly used in battery research and production, including metals, metal oxides, solvents, and separators.

If your requirements exceed the scope of our catalog-packaged products, feel free to consult Aladdin at any time. With our professional customization services and flexible large-package solutions, we will save you valuable time and resources while comprehensively meeting your R&D needs.

An Analysis of the Chemical Composition of Lithium-Ion Batteries

During the operation of a lithium-ion battery, when the lithium stored in the anode undergoes an oxidation reaction, Li⁺ ions are generated. These ions flow through the separator to the cathode with the help of the electrolyte. When the battery is charged, the direction of ion flow reverses; they are reduced to lithium metal and stored back in the anode.

Typically, the lithium in the anode is embedded within a graphite structure. The cathode is composed of lithium metal oxides, where the metal component can be adjusted according to specific requirements. Common cathode materials include LiCoO₂ (lithium-cobalt, abbreviated as LCO), LiMn₂O₄ (lithium-manganese, abbreviated as LMO), LiFePO₄ (lithium iron phosphate, abbreviated as LFP), and Li(NiMnCo)O₂ (nickel-manganese-cobalt, abbreviated as NMC), among others. Even though these alternative chemical substances have similar application scenarios, their specific compositions may vary.

Taking NMC as an example, in the NMC111 chemical substance, the contents of nickel, manganese, and cobalt are equal; whereas in NMC622 and NMC811 chemical substances, the nickel content is increased, significantly reducing the reliance on the scarce metal cobalt.

Selection of Formulation Materials for Lithium-Ion Batteries and Next-Generation Batteries

Aladdin boasts a diverse range of inorganic material combinations that can be used to formulate conventional anodes, cathodes, and electrolytes, while also providing key materials such as metals, solvents, separators, and binders.

As lithium-ion batteries and other inorganic batteries approach their theoretical performance limits, and with the growing global call to reduce reliance on rare, toxic, and/or scarce metals, the prospects for all-organic batteries are becoming increasingly promising. Aladdin's product line not only encompasses traditional inorganic battery materials but also offers a series of synthetic modules for organic battery systems, providing strong support for the diversified development of battery technologies.

Anode Materials

Anodes are usually made from natural or synthetic graphite, but researchers are actively exploring other materials with superior electrochemical performance, such as other carbon allotropes (including carbon black and fullerenes) and non-carbon materials (such as lithium foil, bismuth, germanium, silicon, and tin oxides).

The selection of organic materials is mainly based on their properties, such as aromaticity, resonance, or conjugation. Additionally, they can also be composed of radicals (such as TEMPO) and functional groups (such as carbonyl groups).

Cathode Materials

Cathode materials are mostly transition metal oxides that can accommodate lithium by changing their oxidation states. We also offer a variety of sodium salts and other salts to meet the research needs of non-lithium technologies.

Cathodes can also be composed of various organic materials, such as cetyltrimethylammonium bromide (CTAB), oxalic acid dihydrate, and ferrocene, among others.

Electrolytes

Traditional electrolytes are composed of organic solvents (such as ethylene carbonate) and dissolved salts. Solid electrolytes, on the other hand, have the potential to prevent leakage and enhance battery safety.

Metals

The pure metals and metal alloys used in batteries come in various forms, including aluminum, cobalt, stainless steel, and nickel, available as foils, wires, powders, and rods.

Separators and Binders

Separator materials play a crucial role in controlling heat conduction and include polyethylene, polypropylene, and other polymers in sheet or powder form.

Binders, as inert materials, can tightly bind the active electrode particles of the battery together, ensuring a strong connection between the electrode and the current collector.
