Bhawin uses a diverse array of cathode and anode materials tailored to suit various applications. Additionally, we excel in custom synthesis of lithium-ion cathode, anode, and solid electrolyte powders, ensuring safety, high capacity, prolonged cycle life, enhanced rate capability, and reliable performance even at low temperatures.

Lithium Nickel Cobalt Aluminum Oxide (NCA) Powders

Lithium nickel cobalt aluminum oxide (LiNi0.8Co0.15Al0.05O2), commonly known as NCA, is a cathode material widely adopted in commercial applications. NCA boasts a high usable discharge capacity of approximately 200 mAh g−1 and offers extended storage calendar life compared to traditional cobalt-based oxide cathodes. These batteries are ideally suited for moderate rate applications demanding high energy density.

Lithium Titanium Oxide (LTO) Powders

Lithium titanate (Li4Ti5O12) serves as an electrode material renowned for its outstanding electrochemical stability. It is frequently employed as the anode in lithium-ion batteries, particularly for applications necessitating high rates, prolonged cycle life, and superior efficiency. Batteries based on LTO are recognized for their enhanced safety features and broader operational temperature range.

Lithium Manganese Oxide (LMO) Powders

Lithium Manganate (LiMn2O4), featuring a spinel structure, enables high-rate discharge capabilities. LMO-based batteries are optimally designed for applications demanding elevated discharge rates.

Lithium Manganese Nickel Oxide (LMNO/Spinel) Powders

Lithium manganese nickel oxide, also known as spinel (LiMn1.5Ni0.5O4), emerges as a compelling choice for future lithium-ion batteries, boasting impressive power capabilities alongside an operating voltage of approximately 4.7 V and a capacity of around 135 mA h g−1. With its elevated potential, LMNO-based batteries offer superior energy density compared to lithium cobalt oxide and lithium iron phosphate, making them ideal for high-rate applications.

Custom Anode & Cathode Materials

Bhawin excels in the innovation of novel compositions and particle structures, including nanoscale engineering. Trusted for years, we’re a reliable source for tailored cathode (and anode) materials essential for lithium-ion batteries.

Cathode & Anode Tapes

Bhawin provides a diverse selection of cathode and anode electrode sheets designed to meet various application needs. Our standard electrode sheets are cast onto aluminum (for cathode) or copper foil (for anode) current collectors, and they are conveniently packaged in ready-to-ship bundles of 2, 5, or 10 sheets per material. Bulk quantities are also available upon request.

Customization

Bhawin offers custom tailored solutions for customers with unique specification requirements. Tapes can be modified to accommodate different active material loadings, sheet and/or coating dimensions, coating thickness, and binder type / content upon request.

Solid Electrolytes

At room temperature, solid electrolytes facilitate the conduction of lithium ions and offer a potential alternative to traditional organic electrolytes, which pose risks due to their flammability and toxicity. By enhancing battery safety significantly, solid-state electrolytes also enable the utilization of lithium metal as the anode, resulting in heightened cell voltage and subsequently, enhanced battery energy density.

Sulfide-based Solid Electrolytes

Sulfide-based solid electrolytes stand out as among the most sought-after and promising options for all-solid-state batteries. However, sulfide compounds with high Li-ion conductivity are not readily accessible, posing a challenge for the development of solid-state electrolyte-based Li-ion batteries. Leveraging our deep expertise in advanced materials synthesis, Bhawin has pioneered a process to produce sulfide materials in a manner that holds promise for their integration into Li-ion cells.

Oxide-based Solid Electrolytes

Inorganic oxide-based solid electrolytes are highly coveted for their potential in all-solid-state batteries. Bhawinuses a range of oxide-based solid electrolyte powders, including garnet-type, NASICON-type, and perovskite-type materials. These powders boast exceptional attributes such as high phase purity and crystallinity, fine particle size, and uniform particle size distribution (PSD). These characteristics enable Bhawin’s oxide-based solid electrolyte materials to be processed into structures with superb electrochemical properties.

Polymer-based Solid Electrolytes

Bhawin uses solid polymer electrolytes tailored for rechargeable solid-state lithium batteries. These electrolytes are crafted from specially synthesized polymers intricately bonded with highly conductive lithium salts.

Phosphate-based Solid Electrolytes

Bhawin utilizes solid electrolyte powders based on phosphates, renowned for their exceptional qualities including high phase purity, crystallinity, fine particle size, and uniform particle size distribution (PSD). These attributes enable Bhawin’s phosphate-based solid electrolyte materials to be fashioned into structures boasting outstanding electrochemical properties.

Custom Solid Electrolytes

Bhawin actively engages in the production of various solid electrolyte materials, encompassing sulfide, oxide, and phosphate-based compositions, along with polymer-based variants. Beyond the standard compositions, Bhawin possesses the capability to consistently synthesize custom solid electrolyte compositions, both in small and large quantities, upon request.
Solid electrolytes play a pivotal role in conducting lithium ions at ambient temperatures, potentially substituting conventional organic electrolytes known for their flammability and toxicity. Moreover, solid-state electrolytes significantly enhance battery safety while enabling the utilization of lithium metal as the anode. This facilitates an increase in cell voltage, consequently enhancing the battery’s energy density.

Materials for Sodium-ion Batteries

Similar to lithium-ion batteries, cathode materials play a crucial role in Sodium-ion batteries. The composition of the cathode material directly impacts cell voltage, capacity, and thus, energy density. Sodium-ion cathode materials typically consist of intercalation/de-intercalation compounds, where sodium ions from the cathode are inserted into the host lattice (anode) during charging and extracted during discharging, with minimal alteration in the host material’s structure.
In contrast to lithium, sodium is abundantly available in the earth’s crust, driving significant interest in Na-ion batteries in recent years. The selection of a cathode material with specific chemistry depends on various factors, including cell voltage, capacity, energy and power capabilities, cycle life, and operational temperature.
