Farasis S45 Semi-Solid-State Pouch Cell (46.7Ah / 3.73V / 272Wh/kg)

Farasis S45 Semi-Solid-State Pouch Cell

Specifications

Product Overview

The Farasis S45 is a semi-solid-state pouch cell, representing the next generation of lithium battery technology. The semi-solid electrolyte provides enhanced safety (reduced thermal runaway risk), wider operating temperature range, and longer cycle life compared to conventional NMC cells, while maintaining competitive energy density.

Semi-Solid-State Technology Advantages

• Enhanced safety: Semi-solid electrolyte reduces fire / thermal runaway risk
• Wider temperature range: Better low-temperature performance vs conventional NMC
• Longer cycle life: Typically 2,000-3,000 cycles vs 1,500-2,000 for conventional NMC
• Reduced dendrite formation: Semi-solid electrolyte suppresses lithium dendrite growth
• Higher voltage stability: Compatible with 4.3-4.35V charging

Applications

• Premium passenger EVs (long-range segments)
• High-end energy storage with safety priority
• Aerospace and aviation batteries
• Defense and military applications
• Premium light-mobility (high-performance e-motorcycles)
• Medical devices requiring high safety

How the S45 behaves in a pack

At 8 mm thick this is the thinnest cell in the range, which is the point: for a given envelope you can fit more cells, and the 272 Wh/kg density means the pack does not grow to use the space. The 160 x 231 mm footprint matches the P58, so the same mechanical design and cooling stack can be reused with a different cell – useful when a programme needs a range variant without redesigning the pack. Cycle life is the longest in the range at 2500 cycles to 70% SOH.

Charging to 4.35 V: what your BMS must support

The charge cut-off here is 4.35 V, not the 4.2 V most NMC packs are built around, and the operating window starts at 2.8 V. That has two consequences buyers miss: a charger or BMS set for 4.2 V will leave capacity unused, and one that terminates on a 4.2 V assumption while pushing 4.35 V risks overcharge. Confirm the charger output and the BMS over-voltage threshold before the first sample is built – continuous charge is 54.5 A (1.2C), with 135 A continuous and 227 A pulse discharge.

Matching, storage and supply

Semi-solid cells are graded and matched on capacity and internal resistance before assembly, as with the rest of the range, and shipped in original packaging with UN38.3 and MSDS per batch. Store them at partial state of charge in a cool, dry place if they will not be assembled immediately – long storage at full charge ages any lithium cell, and high-nickel chemistries more than most. See lithium cells wholesale for supply terms.

Product FAQ

Are these cells original factory genuine products?

We have established stable supply channels with first-tier cell manufacturers including Farasis. All supplied cells are original factory genuine products, shipped in original packaging, with batch-level traceability information available.

What is the minimum order quantity (MOQ)?

MOQ depends on model and inventory situation. Semi-solid-state cells typically have higher MOQ than conventional NMC due to limited production scale. Contact us for current stock and MOQ.

Do you support capacity grouping and PACK customization?

Yes. We can perform capacity, internal resistance, and voltage grouping according to customer requirements, and provide PACK structural design, BMS integration, and thermal management solutions optimized for semi-solid-state chemistry.

What about delivery cycle and logistics methods?

Delivery cycle for semi-solid-state cells is typically longer than conventional NMC (4-8 weeks) due to production scale. Cells are Class 9 dangerous goods, transported through qualified hazardous goods logistics channels.

What certifications and testing documents can you provide?

We can provide MSDS, UN38.3 test reports, transport identification reports, factory QC reports, and semi-solid-state specific safety test data.

What are the warranty and after-sales policies?

Warranty scope and duration are subject to original factory policy and contract agreement. Semi-solid-state cells typically carry longer warranty (3-5 years) reflecting the longer cycle life.
