Handling, Storage and Pre-Use Treatment
- Use a dry handling environment before cell assembly to reduce moisture exposure on the coated electrode surface.
- Store opened sheets in a dry environment or inert atmosphere to reduce moisture exposure before use.
- Avoid touching, bending, scratching, or contaminating the coated surface during punching, transfer, and stacking.
- For LTO testing, define the voltage window, matching electrode, electrolyte system, and aluminum current collector handling consistently across comparative experiments.

This LTO electrode sheet requires dry handling and inert atmosphere storage to prevent moisture-induced degradation of the coating. Physical damage to the coated surface must be avoided during punching and cell assembly to maintain electrode integrity.
- Moisture Sensitivity: Store opened sheets in a dry environment or inert atmosphere to reduce moisture exposure before use.
- Handling Precautions: Avoid touching, bending, scratching, or contaminating the coated surface during all handling steps.
- Electrolyte Compatibility: Define the electrolyte system and voltage window consistently to ensure reproducible electrochemical testing.
- Matching Electrode: Select a matching counter electrode with appropriate capacity and voltage range for full-cell studies.
- Infrastructure Requirement: Use a dry handling environment or glovebox for all electrode preparation and cell assembly steps.
What is the significance of the 12 mg/cm2 coating loading and 93.50% active material ratio in this LTO electrode sheet?
The 12 mg/cm2 coating loading defines the areal mass of the active lithium titanate (LTO) layer, directly influencing cell capacity and electrode thickness. The 93.50% active material ratio indicates the proportion of LTO in the dry electrode coating formulation, with the remainder comprising binder and conductive additives. These parameters are specified for reproducible electrode performance and are critical for designing matched full cells.
What cathode electrode specifications are typically needed to pair with this LTO anode sheet for full-cell assembly?
The product description does not provide a specific recommended cathode loading. However, it states that the electrode area (120 mm × 95 mm) and active-material mass (calculated from the 12 mg/cm2 coating loading) can be used to estimate cathode-side matching before assembly. Researchers should determine the appropriate cathode capacity balance based on their chosen electrolyte system, voltage window, and cell design.
What are the required storage and handling conditions for this LTO electrode sheet to prevent moisture contamination?
The electrode sheet must be handled in a dry environment before cell assembly to minimize moisture exposure. Opened sheets should be stored in a dry environment or inert atmosphere, and the coated surface must not be touched, bent, scratched, or contaminated during punching, transfer, and stacking. These precautions are essential to maintain electrode integrity and electrochemical performance.
This single-sided LTO electrode sheet provides a controlled 12 mg/cm2 coating with 93.50% active material ratio on a 1 µm carbon / 12 µm aluminum / 1 µm carbon current collector, with 1.45 g/cm3 compaction density and a 120 mm × 95 mm coating area. It is best suited for defined LTO electrode studies and full-cell matching, provided dry handling and inert or dry storage are maintained before cell assembly.
Positive
- Controlled 12 mg/cm2 LTO loading on carbon-coated aluminum: The single-sided 12 mg/cm2 lithium titanate coating with 93.50% active material ratio provides a defined electrode format for LTO cell assembly and electrolyte compatibility screening.
- Defined carbon-coated aluminum collector architecture: The 1 µm carbon / 12 µm aluminum / 1 µm carbon current collector with 7.25 mg/cm2 areal density gives a known collector mass for full-cell matching and aluminum-collector electrode comparisons.
Trade-offs
- Dry handling and inert storage required: Opened sheets must be stored in a dry environment or inert atmosphere before use, and the coated surface must not be touched, bent, scratched, or contaminated during punching, transfer, and stacking.
- Fixed single-sided format limits design flexibility: This electrode is supplied as a single-sided 120 mm × 95 mm coating at 12 mg/cm2; other loadings, coating areas, collectors, or sheet formats require the separate custom coating service.
