Lithium Batterij Standaard van de Toekomst

Supersized Screwable Scalable Sealed Standard

The old 18650 lithium cell reaches its limits in terms of safety, capacity, recyclability and scalability. The larger these lithium ion packs are, the more hazardous the dangers involved in real world applications. A new standard is nescessary for the growing demand of electrically driven bicycles, cars, motorbikes and boats.

As an independant third party, we have developed a new standard that is more scalable, much safer and more practical in both manufacturing and recycling: the S7 type lithium ion battery cell. The goal is to make these safety requirements met by 2025 for all new lithium battery "packs" consisting of more than 12 individual cells (usually in bicycles, electric cars). The development of the project peaks with a presentation of the s7 lithium standard for the European Uninion. As an inpiration for paving the way towards new regulations and better standards for lithium batteries entering Europe.

  • Higher capacity per cell
  • Less cells per batterypack
  • Cheaper to produce batterypacks
  • Re-usable by manufacturers as well as owners
  • Recyclable by reusing the encasing
  • 4mm thick insulation on both + and -pole
  • 2mm thick insulation on the entire body
  • Safer: less shortcuts and leakages
  • Stackable by screwing the male+ into a female-
  • Inner female- nut screws are deeper than male+ bolt screws, preventing overpenetration by mistake when screwing the ends together
  • A tight fit doubles as a self-sealing mechanism, activating the insulation as a watertight sealant, insuring no luquids/materials go in or out, avoiding shorts of the plus-to-minus area
  • Stackable head-to-tail (for serial) simply screw on or screw off for recycling or reuse in other applications.
  • Stackable back-to-back (for parallel) via standard M2/M3/M4 screws and standard simple to manufacture washers.
  • No soldering required. Making it much less prone to soldering mistakes that can occur lateron (loosened wires fly around creating shorts and fires).
  • 5000 tot 8000 batterijen in een electrische auto, dat zijn 5000 chances for "one-sets-off-the-next" waterfall/domino of explosive potentials with possibly deadly results.
  • To prevent monopolisation by a single large company (sanyo, tesla, panasonic etc) this project is open to the public.
  • Three sizes for future expansions: S7 (M4 screws); S8 (M5 screws); S9 (M6 screws).
