66AH HIGH-PERFORMANCE AND HIGH-SAFETY SOLID-STATE BATTERY | ATOMFAIR

COMMERCIAL GRADE · PRODUCTION

Product Overview
Engineered for high-capacity energy storage applications, this premium pouch cell utilizes an advanced high safety solid state battery framework. Implementing an optimized NCM graphite silicon pouch cell matrix (NCM-Gr/Si,C-SSE), this cell leverages a composite solid-state electrolyte to deliver a remarkable 310 Wh/kg energy density and 625 Wh/L volumetric layout. This 66Ah 3.65V battery architecture supports a secure 5C maximum continuous discharge, an 8C peak discharge burst (30s), and a 3C continuous charge capability. Designed to withstand intensive operational cycles, it maintains strong capacity retention under continuous use from -30°C up to 70°C. It serves as an essential primary cell hardware standard for electric vehicle powertrains, low-altitude aircraft (eVTOL) prototyping, and marine electric vessel development workflows.

Frequently Asked Technical Questions

What are the key advantages of this solid-state battery?

This solid-state cell offers intrinsic safety due to the composite solid electrolyte, high energy density (310 Wh/kg), high power (5C continuous, 8C peak), wide temperature range (-30°C to 70°C), and long cycle life (1000 cycles at 1C/1C with ≥80% retention). It is engineered for next-generation EVs, eVTOL, and electric vessels.

What is the recommended charging/discharging profile?

Standard charge/discharge is 1.0C. Maximum continuous charge is 3.0C, maximum continuous discharge is 5.0C, and peak discharge (30 seconds) is 8.0C (≥30% SOC). For optimal cycle life, operate within -30°C to 70°C.

How does solid-state chemistry improve safety compared to conventional Li-ion?

The composite solid-state electrolyte (C-SSE) is non-flammable and eliminates liquid electrolyte leakage, significantly reducing risks of thermal runaway, fire, or explosion. This makes the cell exceptionally safe for high-energy, high-power applications.

What applications is this battery designed for?

The module is optimized for electric vehicles (EVs), low-altitude aircraft (eVTOL / drones), and electric vessels (ships, boats). Its combination of high energy density, high power, wide temperature tolerance, and safety makes it a versatile solution for future mobility.

This solid-state battery cell requires storage in a dry, ventilated area between 15°C and 30°C. Charge and discharge must be performed within the specified temperature range of -30°C to 70°C, and the peak discharge current of 8C is only permitted when the state of charge is at least 30%.

  • Storage Environment: Store the battery in a dry, ventilated area with temperature maintained between 15°C and 30°C.
  • Charge Current Limitation: Do not exceed a continuous charge current of 3C.
  • Discharge Current Limitation: Maximum continuous discharge is 5C; peak discharge of 8C is allowed for up to 30 seconds only if SOC is 30% or higher.
  • Operating Temperature Range: The battery can operate between -30°C and 70°C, but charging must occur within this range.
  • Prohibited Actions: Do not disassemble, puncture, or expose the battery to fire to prevent thermal runaway.

Follow these steps to safely initialize and handle the solid-state battery cell. Ensure all actions are performed within the specified environmental and electrical limits.

  1. Inspect Packaging and Terminals
    Inspect the battery's packaging and terminal connections for any signs of damage or corrosion before use.
  2. Verify Ambient Temperature
    Verify that the ambient temperature is within the permissible range of -30°C to 70°C for charging.
  3. Connect Charger
    Connect the battery to a charger configured to deliver a maximum continuous charge current of 3C.
  4. Monitor State of Charge
    Monitor the battery's state of charge (SOC) and ensure it remains above 30% before applying any 8C peak discharge pulses.
  5. Store When Not in Use
    Store the battery in a dry, ventilated area at 15-30°C when not in operation to preserve its cycle life.

This 66Ah NCM-Gr/Si,C-SSE solid-state pouch cell delivers 310 Wh/kg and 625 Wh/L with a non-flammable composite electrolyte, but peak 8C discharge requires ≥30% SOC and storage is restricted to 15–30°C.

Positive

  • High safety solid-state electrolyte: The composite solid-state electrolyte (C-SSE) eliminates liquid leakage risks, enhances thermal stability, and reduces thermal runaway potential.
  • High energy and power density: Delivers 310 Wh/kg gravimetric and 625 Wh/L volumetric energy density, with 5C continuous and 8C peak (30 s) discharge for demanding EV and eVTOL loads.

Trade-offs

  • Peak discharge requires ≥30% SOC: The 8C peak discharge (30 s) is only permissible when state of charge is at least 30%, limiting burst power availability under low charge conditions.
  • Narrow storage temperature requirement: Optimal long-term storage is restricted to 15–30°C in a dry, ventilated area, imposing climate-controlled warehousing for inventory management.
