Cell Agnostic
Lithium-ion cells are an essential component of any electric vehicle in today’s market. Cells and the chemistries they package come in an array of chemistries: lithium-nickel cobalt manganese oxide (NCM), lithium-nickel cobalt aluminum oxide (NCA), lithium-iron phosphate (LFP) and lithium-titanium oxide (LTO). Cell packaging formats, which include prismatics, cylindricals and pouch cells, also offer variable performance and pricing. Each cell design targets certain performance goals whether that be high-energy density, high-power density, superior safety, longer cycle life and reliability. Not all cells are the same, and the same holds true for manufacturers of cells.
Moreover, new developments and improvements are being introduced all the time. Performance characteristics, current limitations, and recent breakthroughs in the development of solid-state batteries offer a window into the next generation of storage solutions.
We provide a full range of tailor-made battery system solutions to our customers. In particular, we offer EV battery systems for a wide array of battery cells with different battery chemistries, including lithium iron phosphate, or LFP, and high specific energy density cells, and of different form factors, including cylindrical and prismatic battery cells. Our EV battery systems also have a wide application across electric passenger, commercial and other EVs, including BEVs, plug-in hybrid electric vehicles, or PHEVs, and hybrid electric vehicles, or HEVs.
Bipolar encapsulated structure technology, or BEST
Our Bipolar encapsulated structure technology, or BEST, is designed to ensure thermal runaway of a single battery cell will not propagate throughout the system. It includes thermal sensors to detect thermal runaway, proprietary laser welding and encapsulation processes and equipment and proprietary algorithms to execute additional thermal mitigation. BEST is offered with battery cells with different chemistries (namely NCM and NCA) and form factors (namely cylindrical and prismatic). Our products with BEST have achieved the following:
• enhanced safety: We engineer our EV battery systems to incorporate safety and control features that extend battery lifespans and improve performance. We are one of the few companies in China with the technology to ensure thermal runaway of a single battery cell will not propagate throughout the system,
according to the F&S Report; and
• high energy density: We offer EV battery systems that store greater amounts of energy per unit of mass. Our latest products have achieved an energy density of approximately 180 Wh/kg.
Multifunctional unitized structure technology, or MUST
Multifunctional unitized structure technology, or MUST. This technology was initially designed for LFP prismatic battery cells, which achieved a significant cost reduction of approximately 10% compared to the industry average, according to the F&S Report. Our EV battery systems with MUST are also over 40% higher in space utilization compared with our competitors according to the F&S Report. This is achieved by eliminating modules and reducing components and connections within an EV battery system to allow for battery cells to be directly integrated into the EV battery systems. Our MUST is offered with different battery cells with different chemistries (namely LMO or LFP) and form factors (namely prismatic or cylindrical).
