9. Principle of SLPB (WORLDWIDE PATENT) ① : Al Foil ② : Positive Electrode Based Transition Metal Oxide ③ : Separator Based Porous Polyethylene(PE)+ polymer ④ : Negative Electrode Based Artificial Graphite LiC 6 ⑤ : Cu Foil SLPB technology contains no metal lithium. Only Li-ion passes between the positive and negative poles leaving the cathode and anode materials unchanged. The principle operation is fundamentally different and safer than that of a rechargeable lithium metal battery. The patented folder to folder design reduces IR significantly

10. Abusive overcharge and explosion control are built into cell design: Enhanced Safety with Patented Design  Tabs and plate foil are specially designed patented for safety  Continuous folder to folder with Separator patented design  Low internal impedance design = low heat generation High Power Cell High Energy Density Cell Ultra High Power Cell
