Battery Materials Handled
Nol-Tec possesses a deep understanding of materials commonly used in the industry. We are well-versed in solving material handling challenges such as reducing wear due to the abrasiveness of materials like cathode powder, metal hydroxides, beta spodumene, nickel, manganese and cobalt. We also ensure proper flow out of bins when handling poor flowing materials such as milled lithium (lithium doesn’t flow well when milled) and reducing metal contamination caused by abrasive powders (metal contamination is detrimental to battery performance).
Beta Spodumene is a crystal-like material used in lithium-ion batteries that can store more energy than traditional materials. This material has a higher energy density than other materials, allowing it to store more power in a smaller size. Its use allows for more efficient and longer-lasting batteries that are lighter in weight and more affordable. Beta Spodumene is also a safer material than other materials used in batteries, as it is less prone to overheating and has a lower risk of fire or explosion. It is an eco-friendly material, making it an attractive option for battery manufacturers. This material is becoming increasingly popular in batteries, due to its advantages in energy storage and safety.
Lithium hydroxide is a chemical compound used in the manufacture of rechargeable batteries. It is a white, water-soluble solid that is produced by reacting lithium with water. It has a high capacity for storing energy, making it ideal for use in batteries. Lithium hydroxide is used in lithium-ion, nickel-cadmium, and nickel-metal hydride batteries. In these batteries, it is used to absorb the electrons released during the charging process, resulting in a higher capacity battery. It is also used in air purification systems, as it is able to absorb carbon dioxide and create a more comfortable environment. Lithium hydroxide is an important component for the continued development of efficient, reliable rechargeable batteries.
Metal hydroxides play a crucial role in battery technology. They are commonly used as active materials in rechargeable batteries, particularly in nickel-metal hydride (Ni-MH) batteries. The metal hydroxide, typically nickel hydroxide (Ni(OH)2), serves as the positive electrode or cathode material in these batteries. During the charging process, metal hydroxide undergoes electrochemical reactions, converting into metal oxide. When the battery discharges, the metal oxide reverts back to metal hydroxide. This reversible conversion allows for the storage and release of electrical energy. Metal hydroxides offer advantages such as high energy density, good cycling stability, and low environmental impact, making them valuable components in battery systems.
Cathode powder is a critical component of batteries that helps to store and release energy. It is a powder made from materials such as graphite, manganese dioxide, and lithium. Cathode powder is used in lithium-ion batteries, which are rechargeable and have a high energy density. It is also used in other types of batteries, such as nickel-metal hydride and alkaline. Cathode powder works by chemically reacting with the anode material to produce a flow of electrons and ions when the battery is charged and discharged. It helps to maintain a stable voltage within the battery and helps to regulate the rate of energy transfer. Cathode powder is essential for efficient energy storage and reliable performance of batteries.
Graphite is a form of carbon that is used in the production of batteries. It is an excellent conductor of electricity and is lightweight and non-corrosive, making it an ideal material for use in rechargeable batteries. Graphite has a high capacity for storing and releasing electrical energy, and is capable of providing power for a long period of time. It is also a low cost material and is environmentally friendly, making it a popular choice for use in batteries. Graphite is used in both primary and secondary battery cells to increase the density of the charge and to provide a more efficient and durable energy storage solution.
Manganese powder is a grey/black powder, consisting primarily of manganese oxide, also known as manganese dioxide. It is widely used in the production of steel and other alloys, as well as in a variety of other industrial processes. It is also used in the production of batteries, fertilizers, and glass, and as an additive in paint, plastics, and rubber. Manganese Powder can be hazardous if inhaled, and should always be handled with appropriate safety equipment. It is also important to store it in a dry, well-ventilated area away from moisture and direct sunlight.
Cobalt is a transition metal found in the Earth’s crust. It is a hard, grey-white metal with a bluish tint that is typically found in ore deposits, and can be extracted from its ores using various techniques. Cobalt is used to make alloys, magnets, batteries, and catalysts, and is also used in the production of paint, glass, and ceramics. It is also used in nuclear reactors, and in medical treatments for cancer and other diseases. Cobalt is a highly toxic metal, and should be handled with care. Its unique properties make it an essential component of many everyday objects, from jet engines to dental fillings.
Nikel is a popular metal that has a bright silver-white color and is highly resistant to corrosion. It is a ferrous metal with a high melting point and is malleable and ductile. In addition, it is magnetic and has a variety of industrial and consumer applications. Uses include batteries, coins, jewelry, electrical wiring, aircraft parts, and surgical implants. It is also alloyed with other metals to form strong and lightweight alloys, such as stainless steel and nickel-based superalloys. Nikel is an essential element in many industries, as it is used in products ranging from coins to medical prostheses.
Top four design considerations for battery/eV plants
1. DENSE PHASE PNEUMATIC CONVEYING – to reduce component wear and metal contamination during material transfer.
Reducing component wear within a manufacturing process plays a crucial role in minimizing the possibility of metal contamination. When conveying an abrasive material such as metal hydroxides or cathode powder, the wear and tear of components can lead to the release of small metal particles into the process. These particles can contaminate the products, leading to compromised performance and quality.
By designing systems to utilize dense phase pneumatic conveying, an emphasis is placed on reducing material velocities, resulting in less component wear, therefore lower maintenance and no metal contamination, ensuring a higher quality product.
2. CLOSED LOOP SYSTEMS – to eliminate moisture and other contaminants while reducing operating costs.
Materials like lithium hydroxide and metal hydroxides may negatively react to moisture or other contaminants and elements found in atmospheric air. Designing systems with closed-loop pneumatic conveying offers significant benefits in reducing moisture and other forms of contamination. In open systems, atmospheric air can introduce moisture, and other contaminants into the material handling process, posing risks to the quality and integrity of the materials. Closed loop conveying, on the other hand, provides a controlled and enclosed environment for material transfer, allowing only conditioned gas to contact the material. Closed loop systems also add the benefit of reduced operating costs by re-using expensive conditioned air instead of continuously exhausting gas out of the system.
3. PNEUMATICAL BLENDING MATERIALS – to reduce metal contamination and dust exposure.
Pneumatic blending offers a valuable solution to both reduce metal contamination, and enhance operator safety by minimizing dust exposure. Traditional mechanical blending methods generate excessive shear forces that can lead to the release of small metal particles into the process. However, pneumatic blending is a low shear blending process used to gently mix or homogenize powdered material. By utilizing controlled pulses of compressed air to blend material, contact and abrasion between metal components is significantly reduced, mitigating the generation of metal particles. Furthermore, the use of pneumatic blending contains and controls dust in an airtight hopper, eliminating the release of hazardous air borne particles and minimizing operator exposure.
4. EFFECTIVE DUST CONTROL – to ensure a safe manufacturing environment for operators.
The combination of pneumatic conveying, pneumatic blending and dust collection systems designed to reduce operator exposure collectively contribute to significantly enhancing operator safety as it relates to hazardous dust exposure. Pneumatic conveying systems employ enclosed pipelines and controlled airflow to transfer materials, effectively minimizing dust release into the surrounding environment. This containment reduces the risk of inhalation and potential health hazards for operators. Additionally, pneumatic blending techniques, which utilize a contained and low shear blending environment, further reduce operator exposure compared to other traditional mechanical mixers.
