Graphite-density and PVDF-coated separator lithium-ion design unlocks capacity-fade-resistant batteries without extra licensing.
The patent specifies a lithium-ion (or lithium-polymer) cell using a graphite anode at 1.2–1.5 g/cm³, a LiNiO2 cathode at 3.0–3.3 g/cm³, and a PVDF-coated separator that mechanically holds the electrode stack together. This combination targets capacity fade by stabilizing electrode/separator contact through cycling-related stress and performance drift. Previously, manufacturing cells matching these specific electrode densities and PVDF separator approach required permission from the patent holder.
Build higher cycle-life lithium-ion packs for drones, EV accessories, and power tools using capacity-fade-resistant cell stacks.
