LCO Artificial Graphite Anode Dry Pouch Cell(Multiple Specs)

Name: LCO / Artificial Graphite Anode Pouch Dry Pouch Cell (Multiple Specs)

Cell Type: LCO-Graphite Pouch Dry Cell (4.4 V High-Voltage)

Product Code: XN-LCO-Gr

Description:

LCO / Artificial Graphite Anode Pouch Dry Pouch Cell pairs high-voltage lithium cobalt oxide (LCO) cathode with high-capacity artificial graphite anode in a fully assembled but unfilled (dry) pouch format. As a result, this configuration delivers the proven cycle stability and manufacturing maturity of the classic LCO/graphite chemistry — the workhorse of the consumer electronics industry — combined with the higher energy density unlocked by 4.4 V operation. Furthermore, the dry (unfilled) pouch format allows customers to inject their own electrolyte formulations, making this cell ideal for high-voltage electrolyte and additive research targeting smartphones, tablets, wearables, and other premium consumer electronics applications.

Application:

This dry pouch cell serves as a versatile research platform for consumer electronics battery development, including high-voltage electrolyte formulation studies (the cell ships unfilled, allowing customers to inject their own electrolyte), 4.4 V LCO cathode performance evaluation, additive screening for high-voltage CEI stability, full-cell prototyping for premium smartphones, tablets, drones, and wearables, and academic studies of LCO/graphite electrochemistry under high-voltage stress.

Characteristics:

4.4 V high-voltage operating window

Extended upper voltage limit to 4.4 V unlocks 170 mAh/g specific capacity from the LCO cathode — significantly higher than conventional 4.2 V LCO operation (~145 mAh/g). As a result, customers gain meaningful energy density improvement without changing electrode chemistry, ideal for high-voltage electrolyte and additive research targeting premium consumer electronics applications.

Mature, industry-standard LCO/graphite chemistry

The LCO + artificial graphite combination is the most extensively characterized lithium-ion chemistry, powering the consumer electronics industry for over two decades. Therefore, this cell provides a reliable benchmark with rich published reference data — ideal for studying how electrolyte additives or operating conditions deviate from the established baseline.

Stepped formation protocol for high-voltage CEI stability

The recommended formation uses a multi-step current protocol (0.1C → 0.2C → 0.6C across three voltage stages) rather than a single-step charge. Consequently, this gradual approach builds a more stable cathode-electrolyte interface (CEI) on LCO at 4.4 V, reducing first-cycle losses and improving long-term cycling stability — a critical practice for high-voltage LCO research.

Dry (unfilled) pouch design for electrolyte studies

The cell ships fully assembled but without electrolyte. Therefore, customers can inject their own electrolyte formulations to study high-voltage electrolyte stability, additive effects on CEI formation, and SEI behavior on graphite — critical capabilities for advancing LCO toward 4.5 V and beyond.

Standardized stacked pouch architecture

Stacked-electrode (laminated) construction with N/P ratio of 1.1 and PE 9+3 composite separator. Therefore, results are reproducible across labs and comparable with industry benchmarks for LCO/graphite cells.

Multiple capacity grades + custom specifications

Standard grades cover 1 Ah / 2 Ah / 5 Ah. Furthermore, custom voltage windows (4.2 V / 4.4 V / 4.45 V), alternative separators, and electrode dimensions are available on request to match specific research requirements.

Recommended Activation Protocol:

1. Inject electrolyte at 3 g/Ah ratio. 2. Vacuum-seal the pouch under inert atmosphere. 3. Aging: hold at 45 °C for 24 h. 4. Pre-formation rest: 5 minutes. 5. Stage 1: charge at 0.1C for 20 minutes, cutoff 3.2 V. 6. Rest 2 minutes. 7. Stage 2: charge at 0.2C for 30 minutes, cutoff 3.9 V. 8. Rest 2 minutes. 9. Stage 3: charge at 0.6C for 80 minutes, cutoff 4.4 V. 10. Final aging: hold at 45 °C for 24 h before subsequent cycling tests.

Packaging & Storage:

Cells ship vacuum-sealed under inert atmosphere in moisture-barrier packaging. Therefore, customers should store sealed in a cool, dry environment, protected from moisture. Open packaging in a dry-room or glovebox environment immediately before electrolyte filling.

Safety:

For research and industrial use only. Activated lithium-ion cells contain flammable electrolyte and high-energy electrode materials. Wear PPE during cell handling and electrolyte filling. Never short-circuit, overcharge, overdischarge, puncture, or expose cells to high temperatures (> 60 °C). High-voltage LCO operation at 4.4 V poses additional CEI degradation and oxygen release risks under thermal abuse; conduct all testing in well-ventilated, controlled environments. Refer to SDS for complete safety information.
