Our technology has unlocked the potential of silicon-based anodes, delivering a step change in energy-dense materials. Backed by over 170 patents and an extensive portfolio of industry-leading cell manufacturing and automotive partners, we are paving the way to a sustainable, electrified future.
This means it has enormous scope to make cells with a higher energy density. Silicon is currently being adopted as a partial replacement for carbon in battery anodes, but problems arise from expansion and contraction when the cells are charged and discharged. Nexeon's NSP1™ and NSP2™ flagship materials have overcome this hurdle, making silicon anodes a viable transformative technological solution at scale.
Introducing the era of Generation 2 battery materials.
Conventional silicon expands under charge, breaking and degrading the electrode. This results in rapid cell capacity fade, and therefore overall battery capacity fade.
NSP2™ unlocks the full specific capacity benefits of silicon, allowing for greater replacement of graphite.
Our proprietary anode structure contains the expansion characteristics, achieving a greater capacity over graphite whilst retaining a good cell cycle life.
Our NSP1™ technology replaces a small fraction of the graphite whilst leveraging the higher specific capacity of silicon. Silicon expands within the structure, but does not degrade the cell, providing good cycle life.
NSP1™ for use in silicon-graphite hybrid electrode up to 10% by weight.
Silicon’s ability to hold more lithium ions in a given volume unlocks a greater variety of cell design options.
Nexeon® materials are compatible with all type of lithium-ion battery cells, including cylindrical, prismatic and pouch cells.
