This document outlines critical environmental and electrical constraints for safe operation of the semi-solid battery cells. Adherence to these parameters is essential to prevent performance degradation and ensure safety.
- Voltage Window: Operate the battery strictly within 2.75V to 4.2V to avoid over-discharge or overcharge damage.
- Temperature Limits: Avoid sustained exposure to temperatures above 60°C during operation or storage.
- BMS Requirement: Always use a Battery Management System with overcurrent and low-temperature protection.
- Pre-conditioning: Pre-condition cells at 25°C before first high-rate discharge to stabilize internal chemistry.
- Storage Environment: Store cells in moisture-barrier vacuum-sealed bags to prevent electrolyte degradation.
Follow these steps to prepare and use the battery cells safely and effectively. Proper initialization ensures optimal cycle life and power performance.
Required Equipment: Battery Management System (BMS)
- Inspect Battery
Inspect the battery for any physical damage or swelling before handling. - Pre-condition Cell
Pre-condition the cell at 25°C for at least 2 hours prior to first high-rate discharge. - Connect BMS
Connect the battery to a BMS with overcurrent and low-temperature protection. - Operate Within Voltage Range
Operate the battery within the voltage range of 2.75V to 4.2V during charge and discharge. - Avoid High Temperature
Avoid exposing the battery to sustained temperatures above 60°C during operation. - Store Properly
Store the battery in a moisture-barrier vacuum-sealed bag when not in use.
How does the 5C continuous discharge capability affect the cycle life relative to the stated 800 cycles at 1C/1C?
The 800 cycles to 80% SOH are certified under 1C/1C charge/discharge conditions. While the cell supports 5C continuous and 10C pulse (3 min) discharge, sustained high-rate cycling will accelerate capacity fade because the cycle life guarantee is based on 1C/1C. For applications demanding repeated high-rate discharge, a derating factor should be applied; the semi-solid design mitigates but does not eliminate rate-dependent degradation, and a BMS with temperature monitoring is required to stay within the 60°C limit.
What voltage and temperature constraints must be met when integrating this semi-solid battery into an eVTOL or high-performance EV pack?
The cell must be operated strictly between 2.75V and 4.2V, and discharge is allowed from -40°C to 60°C. A BMS with overcurrent and low-temperature protection is mandatory, and cells must be pre-conditioned at 25°C before the first high-rate discharge. The semi-solid electrolyte eliminates leakage but requires mechanical compression in the pack to maintain electrode contact. Manufacturing compliance with ISO 9001:2025 and IATF 16949 supports automotive/aerospace integration.
What storage and handling precautions are necessary to preserve the safety and performance of these semi-solid electrolyte pouch cells?
Cells are shipped in moisture-barrier vacuum-sealed aluminum foil bags and should be stored in anti-static packaging to prevent electrostatic damage. Avoid sustained temperatures above 60°C and never exceed the 2.75V–4.2V voltage window. The semi-solid electrolyte reduces flammability compared to liquid electrolytes, but mechanical puncture and crushing must be avoided. Use a BMS with low-temperature protection to prevent charging below 0°C (implied by the -40°C discharge limit).
The ATOMFAIR Semi-Solid Battery Long Cycle Series (AFEPSLC10674172, AFEPSLC11087188, AFEPSLC110105230) offers high energy density (300–370 Wh/kg) and 5C continuous/10C pulse discharge capability, but requires strict voltage (2.75V–4.2V) and temperature (≤60°C) management, along with mandatory BMS integration for safe operation.
Positive
- High energy density and power output: Energy density of 300–370 Wh/kg combined with 5C continuous and 10C pulse (3 min) discharge enables lightweight, compact packs for demanding applications like eVTOL and high-performance EVs.
- Wide operating temperature range: Reliable discharge from -40°C to 60°C supports deployment in extreme environments without performance degradation.
Trade-offs
- Strict voltage and temperature limits: Operation must be confined to 2.75V–4.2V and sustained temperatures above 60°C must be avoided to prevent damage or safety risks.
- Mandatory BMS with protection features: A battery management system with overcurrent and low-temperature protection is required, adding system complexity and cost for integration.
