Featured Lithium Battery Chemistries

Traditional LFP

Lithium iron phosphate, or LFP, is known as the most stable lithium battery chemistry. Significantly reducing the risk of thermal runaway makes LFP batteries much safer and less prone to catching fire. LFP also boasts a longer cycle life than other lithium-ion battery chemistries, offering a long-term, cost-effective energy storage solution. Additionally, its environmentally friendly nature sets this chemistry apart, as it contains fewer toxic materials and is easier to recycle. 

Dragonfly Energy’s versatile, chemistry-agnostic process enables us to work with various types of LFP raw materials tailored to specific applications. This flexibility allows us to achieve optimal performance based on an application’s unique requirements, facilitating the development of larger, more durable LFP solutions optimized for energy storage purposes, as well as smaller LFP solutions designed for rapid charging capabilities.

PFAS-Free LFP

Dragonfly Energy is committed to environmental protection, human health, and regulatory compliance by seamlessly collaborating with a diverse range of polymers, which grants us the flexibility to effortlessly explore PFAS-free alternatives.

Notorious for their persistence in the environment, ability to accumulate in living organisms, and negative human health impact, PFAS chemicals (also known as Forever Chemicals) pose significant risks. Regulatory agencies are even implementing stricter regulations on their use. In particular, the EU is considering a ban on PFAS chemicals and all products containing PFAS. 

By eliminating harmful PFAS chemicals from our processes and products, we can ensure we do not contribute to adverse health and environmental effects linked to these chemicals.

NMC

NMC (Nickel Manganese Cobalt) offers a powerful combination of high energy density, fast charging capabilities, and exceptional versatility. With a high energy density, batteries utilizing NMC chemistry can store significant amounts of energy in a compact form factor, making them ideal for applications where space and weight are critical considerations. The fast charging capabilities of NMC allow for quick recharging times, providing users with increased convenience and efficiency. Furthermore, NMC’s versatile cathode chemistry allows us to tailor the ratios of nickel, manganese, and cobalt to optimize specific performance characteristics such as energy density, power output, and cycle life, ensuring batteries meet the unique demands of a range of applications.

LCO

Lithium Cobalt Oxide (LCO) battery chemistry is renowned for its high energy density, making it ideal for applications where energy storage in a compact and lightweight package is essential, such as portable electronic devices. The high voltage output of LCO cathodes allows for efficient energy conversion and delivery, providing a significant advantage for applications requiring substantial power output, including electric vehicles. Additionally, LCO batteries offer fast charging capabilities, making them suitable for scenarios where quick recharging is crucial. These characteristics combine to make LCO batteries a versatile and efficient choice for a wide range of high-demand applications.

Sodium-Ion

Sodium-ion chemistry has risen as a cost-effective alternative for energy storage applications due to the element’s abundance and lower cost. Sodium can also be an environmentally friendly chemistry option, as it is widely available, and its extraction excludes environmentally harmful mining practices. Safety is another significant advantage of batteries using sodium-ion chemistry as they can be less prone to thermal runaway, reducing the risk of fire or explosion. While still under development, sodium-ion batteries also have the potential to achieve high energy density levels, further enhancing their suitability for various applications.

With Dragonfly Energy’s versatile manufacturing process, we have the ability to accommodate a wide range of chemistries, including sodium-ion, enabling seamless integration and scalability across different chemical compositions.

Nonflammable Solid State

Known as the holy grail of battery technology, nonflammable all-solid-state batteries eliminate the risk of thermal runaway, leakage, and fire by replacing flammable liquid electrolytes with nonflammable solid materials. These batteries can achieve higher energy densities, allowing them to store more energy in a smaller and lighter package, making them particularly suitable for applications where space and weight are critical considerations. Additionally, nonflammable solid-state batteries offer the potential for a longer cycle life and enhanced durability, translating to longer-lasting batteries that need less frequent replacement, ultimately lowering costs and reducing environmental impact. 

Dragonfly Energy’s unique dry electrode manufacturing process enables our development of nonflammable all-solid-state batteries.

Advanced Battery Research

Dragonfly Energy takes a data-driven approach to battery R&D. By creating digital twins of each battery cell using a LIMS (Laboratory Inventory Management System) tool, we have analyzed performace based on the impact of every material and process step. This method not only streamlines development but also allows potential weaknesses to be identified early on, leading to more efficient and reliable batteries and finished products.
