Inventors of Rolled-Ribbon® Technology
Cells
Cells are the foundational elements for all battery systems. At the end of the day, no battery system can be any better than its underlying cells. Better cells – better batteries. Rolled-Ribbon cells provide superior performance and value for high-power high-capacity battery systems. Listed below are our standard cells.
| Type | Cell Model Number | Voltage | Capacity | Discharge | Charge |
|---|---|---|---|---|---|
| LFP | 136-15-LFPE04A | 3.2V | 15Ah | 5C | 2C |
| LFP | 165-15-LFPE04A | 3.2V | 22Ah | 5C | 2C |
| LFP | 165-28-LFPE04A | 3.2V | 45Ah | 5C | 2C |
Notes: (1) Voltage is nominal. (2) Capacity is based on standard charge-discharge rates. (3) Discharge and Charge are the maximum continuous rates.

Battery Modules
Battery modules package cells into modular elements for battery systems. Rolled-Ribbon battery modules extend the virtuous electrical and thermal properties of Rolled-Ribbon cells to battery modules. Listed below are only a few of our standard battery module configurations.
| Configuration | Cell Model Number | #Cells | Voltage | Capacity |
|---|---|---|---|---|
| 1C15S1P | 136-15-LFPE04A | 15 | 48.0V | 15Ah |
| 1C08S1P | 165-15-LFPE04A | 8 | 25.6V | 22Ah |
| 1C12S1P | 165-15-LFPE04A | 12 | 38.4V | 22Ah |
| 1C15S1P | 165-15-LFPE04A | 15 | 48.0V | 22Ah |
| 1C08S1P | 165-28-LFPE04A | 8 | 25.6V | 45Ah |
| 1C12S1P | 165-28-LFPE04A | 12 | 38.4V | 45Ah |
| 1C15S1P | 165-28-LFPE04A | 15 | 48.0V | 45Ah |
Notes: (1) Voltages assume the indicated Configuration with LFPE04A cells. (2) Capacities are based on the indicated Cell Model Number.

Evaluation Kits
As is apparent from the product descriptions above, Rolled-Ribbon produces scalable battery systems with unparalleled performance that are “tough as nails”. The unique Rolled-Ribbon cell design enables the construction of battery systems with stacked-cell battery modules that do not require welding of any kind. This means that cell failures no longer require the scrapping of entire battery modules. Failed cells can be removed and replaced. Cells can be harvested from battery modules and repurposed. The cell design provides a large cell terminal surface area for high rate capability and high thermal conductivity, resulting in cooler operation with minimal temperature gradients and thermal management.
