As battery technology continues to advance, International Battery (IB) is at the forefront of renewable energy, delivering low cost, high energy lithium-ion batteries. IB manufactures two types of lithium-ion chemistries: Lithium Iron Phosphate (LFP) and Lithium Nickel Cobalt Manganese (NiCoMax) in a variety of sizes. The IB product lines offer safe and reliable solutions for a wide variety of applications including transportation, stationary/energy storage, and military.
As with all types of energy storage, safety is our number one concern. Safety is engineered in at the chemical level – from electrolyte design through to electrode material selection and electrode materials processing. The large-format, prismatic cell design by itself provides a safe and robust package. Safety is also engineered in at the system level through 100% monitoring of cell voltages and temperatures, as well as through individual cell balancing and fail-safe systems-level protection. Safety testing has included short circuit, overcharge, over discharge, abusive heating, thermal shock, vibration and bullet penetration.
Battery Manufacturing
Environmental stewardship is key to International Battery’s operations. IB takes enormous pride in our ‘green’ cell manufacturing. IB’s lithium-ion electrode coating processes replace environmentally burdensome organic solvents with water – no solvent evaporation, no solvent burning or complex solvent recovery processes.
See our recently released white paper feature in Battery Power Products and Technology. It details the International Battery process and highlights the advantages vs. solvent based processes. Please click here to view white paper.
Battery Format
Large energy storage applications require a very large number of cells or a much smaller number of large cells. Most of the world’s lithium batteries are produced as small cylindrical cells; the largest typical size is ~ 3 Ah per cell. Large “pouch” type prismatic cells have emerged at up to 10 Ah per cell. International Battery is one of the few global companies with the ability to produce single large prismatic lithium-ion cells that are 50 Ah and larger.

Cell Design
The use of phosphates in the cathode material inherently stabilizes the cell's response during an overcharge or short circuit condition. Furthermore, the use of licensed raw material ensures a non-patent-infringing design.
The use of a lithiated Nickel Cobalt Manganese Oxide (NiCoMax) instead of Lithiated Cobalt Oxide (Cobalt) provides excellent thermal stability under abusive overheating conditions.

System Design
International Battery's proprietary Battery Management System (BMS) is engineered to further enhance and maximize the safety of our LFP and NiCoMax battery technology. Temperature and voltage are monitored for each and every cell. Every cell can individually charge balanced or discharge balanced as required.
