2. Pulling Together the Requirement Form

Once we’ve aligned on the basics, it’s time to turn ideas into concrete parameters: We guide you through a concise form to capture technical details—preferred BMS communication (CANbus, UART, RS-232), connector types, capacity range, and mechanical dimensions.
Why does this matter? This structured document ensures no details slip through the cracks, letting us move from vague concepts to clear engineering specs efficiently.

3. Draft Plan & Estimated Delivery Schedule

With your requirements in hand, we share a preliminary project outline: This includes 3D renderings, wiring diagrams, and a tentative production timeline (typically 12–15 weeks).
Your role here? Review the plan and confirm that the model, specs, and delivery window align with your expectations.

4. Technical Specification & 3D Design Phase

Once the draft plan is confirmed, we shift to visualizing your battery early: You’ll receive a detailed spec pack featuring a 3D model, wiring diagram, BOM lists, thermal layout, and housing design.
Collaboration is key here: We identify potential conflicts upfront (e.g., connector clearance issues, heat dissipation needs) and iterate until the design “clicks.”

5. Prototype (NPI) Production & Testing

After finalizing the design, we move to prototype production—starting with rigorous cell matching: Individual cells are sorted by voltage (±5 mV), internal resistance (±15 mΩ), and capacity (±5 mAh) to ensure consistency and safety.
Next, we run a full test regime: This includes cycle life testing (≥ 100 cycles), short-circuit checks, overcharge/over-discharge protection verification, thermal management tests, and UN38.3 compliance verification.
We also focus on industry-grade BMS debugging: Validating communication stability (CANbus/UART/RS-232), overvoltage/undervoltage protection, and temperature fault triggers.

6. Feedback & Iteration

Once testing wraps up, we share a detailed report—and invite your feedback for minor adjustments. For example, if voltage sag exceeds expectations or casing geometry needs tweaks, we’ll fine-tune the design promptly.
The goal? Fast resolutions that keep your project momentum intact.

7. Finalization & Production Preparation

After iterations, we formalize standardized documentation: This includes all technical specs, test procedures, assembly instructions, and packaging guidelines.
We also lock in quality control protocols: These cover cell matching, insulation testing, thermal runaway protection, and leakage inspection.
Additionally, we handle logistics & compliance: From packaging design (IP 67/68) to UN38.3 shipping certification and import/export documentation, we’ve got you covered.

8. Small-Batch Delivery

Finally, we ensure careful packaging: Anti-static wrap, shock-absorbent inserts, and robust outer cases guarantee your batteries arrive safely.
You’ll stay in the loop with delivery confirmations: We notify you at every milestone—shipped, in transit, customs cleared, delivered.
And our support doesn’t end there: Post-shipment, we’re available for performance monitoring, firmware updates, or lifecycle testing—whatever keeps your project on track.

Custom lithium battery to Help You Kickstart the Project

To streamline your start, we’ve prepared key resources:

✅ A downloadable Project Requirement Form to quickly fill in your specs
✅ A BMS Communication Matrix to identify which protocol suits your device
✅ A Prototype Test Report Template to clarify what we test and how we measure results
(Download links or CTAs can be inserted here)

Our Customer Cases

For example, one of our medical equipment clients needed a slim, high-capacity battery for long-duration operation. Their off-the-shelf options failed to fit the enclosure, and performance lagged.

Here’s how we solved it:
Through video consultations and rapid iterations, we converged on a viable design in just 5 weeks.
From first communication to small-batch delivery, the entire project took 12 weeks—with zero rework.

The client reported smoother integration and reliable long-term performance—exactly the outcome they needed.

Poor Li-ion Cell Consistency: What’s the Root Cause and How to Solve It?

A Critical Path to Improving Li-ion Battery Pack Performance and Service Life

In Li-ion battery systems, poor consistency among cells is widely recognized as a core issue impacting the performance, safety, and lifespan of the entire battery pack. It not only limits the effective energy output but also introduces risks such as thermal runaway and uneven degradation during cycling.

This article analyzes poor consistency across multiple dimensions—capacity, internal resistance, voltage, self-discharge rate, and thermal response—and outlines the underlying causes and solutions to improve reliability and operational efficiency of Li-ion battery packs.

What Is Poor Li-ion Cell Consistency?

Poor Li-ion Cell consistency refers to significant variations in key electrical characteristics among Li-ion battery cells within the same pack or production batch. It is typically manifested in the following ways:

1. Capacity Inconsistency

When the rated or actual discharge capacity difference between cells exceeds ±3%, the performance of the entire Li-ion battery pack is limited by the weakest cell (the “barrel effect”), reducing usable capacity by up to 15%.

2. Internal Resistance Inconsistency

A ≥5% difference in internal resistance causes some cells to overheat during charge/discharge cycles, accelerating aging and triggering a vicious cycle:
higher resistance → higher temperature → further resistance increase.

3. Voltage Inconsistency

If the open-circuit voltage (OCV) deviation exceeds 0.05V, cells in series configurations are prone to imbalance—low-voltage cells may be over-discharged, and high-voltage cells overcharged, leading to cycle instability and safety concerns.

4. Self-Discharge Rate Differences

Variations in self-discharge rates cause SOC (state of charge) divergence after idle storage. The K-value (voltage drop over time) should be used to detect and screen out abnormal cells. Failure to do so increases pack inconsistency over time.

5. Thermal Response Inconsistency

If temperature differences between cells exceed 5°C during operation, localized hot spots may accelerate aging, widening performance disparities further.

Causes of Poor Li-ion Cell Consistency

1. Manufacturing Process Variations

Uneven slurry coating and variations in active material density

Inconsistent roll-pressing thickness

Errors in electrolyte injection or sealing processes

These factors result in initial inconsistencies in Li-ion battery cells at the production stage.

2. Amplification During Use

Small initial differences become magnified through charge/discharge cycles:

Lower-capacity cells are more prone to over-discharge, damaging active material

Higher-capacity cells may remain near overcharge conditions, increasing the risk of lithium plating

3. Safety and System-Level Impacts

Risks of localized lithium plating and thermal runaway increase significantly (see “Li-ion Battery Safety Issues and Failure Analysis”)

BMS (Battery Management System) balancing strategies cannot fully compensate for long-term physical differences between cells

Solutions to Improve Cell Consistency

Manufacturing-Side Improvements:

Slurry Coating and Roll-Press Optimization:
Control electrode sheet density variation within ±1.5%to ensure uniform active material distribution.
Vacuum Drying Temperature Uniformity:
Maintain drying oven temperature deviation under 3°Cto ensure uniform electrolyte behavior and separator integrity.
Multi-Parameter Cell Sorting and Grouping:
Sort and assemble cells based on capacity, internal resistance, and voltage, ensuring matched characteristics before pack assembly.

Application-Side Improvements:

Thermal Management at Module Level:
Keep temperature differences across modules within 5°Cto prevent uneven degradation.
Intelligent Balancing System:
Use active balancing strategies(e.g., energy transfer-based BMS) to dynamically equalize SOC across cells.
Routine Monitoring and Maintenance:
Continuously track internal resistance and voltage changes to detect and isolate underperforming cells early.

Final Thoughts: Consistency Is the Foundation of Battery System Safety

While not always a visible parameter, cell consistency is the underlying logic of long-term reliability in any Li-ion battery system. By combining precision-controlled manufacturing with real-time system-level balancing, manufacturers can significantly improve battery pack consistency, extend service life, and ensure safety under demanding conditions.

For high-performance Li-ion battery pack applications—such as energy storage systems (ESS), power tools, and medical devices—cell consistency is the critical factor that distinguishes a qualified product from an outstanding one.

Exploring Lithium-Ion Batteries: Understanding Lithium-Ion Battery Materials

A Deep Dive into the Core Components of Li-ion Batteries Technology

In today’s rapidly advancing technological world, lithium-ion batteries (Li-ion batteries) have become indispensable. From smartphones and laptops to electric vehicles and large-scale energy storage systems, Li-ion batteries are driving modern life thanks to their high energy density, long lifespan, and low self-discharge rate.

Let’s break down the fundamental components of a Li-ion battery—starting from cathode and anode materials, to electrolytes, separators, and auxiliary materials—and understand how they influence performance, safety, and cost.

I. Cathode Materials: The Performance Determinants

1. Lithium Cobalt Oxide (LiCoO₂)

Advantages: High energy density (~200mAh/g), stable voltage platform, widely used in smartphones, laptops, and other 3C products.

Disadvantages: Scarce cobalt resources, high cost, and poor thermal stability, which may pose safety risks at high temperatures.

2. Lithium Manganese Oxide (LiMn₂O₄)

Advantages: Low cost, high safety, suitable for power tools and low-speed electric vehicles.

Challenges: Relatively low capacity (~120mAh/g), and manganese dissolution during cycling, leading to performance degradation.

3. Ternary Materials (NCM/NCA)

Advantages: High energy density (~220mAh/g), with performance optimized by adjusting nickel (Ni), cobalt (Co), and manganese (Mn) ratios. The mainstream choice for electric vehicles.

Trends: High-nickel formulations (e.g., NCM811) can further increase energy density but require solutions for thermal runaway risks and cycle life issues.

4. Lithium Iron Phosphate (LiFePO₄)

Advantages: Ultra-long lifespan (>10,000 cycles), excellent thermal stability, widely used in electric buses and energy storage systems.

Innovation Directions: Manganese doping or composite with ternary materials to enhance voltage platform and energy density.

II. Anode Materials: The Key to Energy Storage

1. Graphite

Mainstream Choice: Theoretical capacity of 372mAh/g, low cost, and mature technology, but limited fast-charging performance.

2. Silicon-Based Materials

Future Trend: Theoretical capacity up to 4200mAh/g, but suffers from large volume expansion (~300%). Solutions include nanostructuring and carbon coating to improve stability.

3. Lithium Titanate (Li₄Ti₅O₁₂)

Advantages: “Zero-strain” material with extremely long cycle life, ideal for high-safety applications such as medical devices.

III. Electrolytes: The Ion Conduction Highway

The electrolyte is the ionic “highway” inside a Li-ion battery, enabling lithium ions to move between the anode and cathode during charge and discharge. Liquid electrolytes are most common, typically consisting of a lithium salt dissolved in organic solvents.

LiPF₆is the most commonly used lithium salt, accounting for up to 43% of electrolyte costs.
Organic solvents like ethylene carbonate (EC), dimethyl carbonate (DMC), diethyl carbonate (DEC), and ethyl methyl carbonate (EMC)are used in blends to optimize performance and stability.

The choice of electrolyte affects not only ionic conductivity but also cycle life and thermal performance.

IV. Separator: The Battery’s Safety Guardian

Though thin and passive, the separator plays a critical safety role in preventing internal short circuits by physically separating the cathode and anode while allowing lithium ions to pass through. Most commercial separators are polyolefin-based microporous membranes made from polypropylene (PP) and/or polyethylene (PE), including:

PE single-layer membranes
PP single-layer membranes
PP/PE/PP trilayer membranes

These separators must exhibit excellent mechanical strength and thermal shut-down behavior to ensure long-term safety.

V. Auxiliary Materials: The Unsung Heroes

While not active in electrochemical reactions, auxiliary materials are essential in optimizing battery structure and performance.

1. Conductive Agents

These improve the electrical connectivity between particles within the electrode. Common conductive agents include carbon black, vapor-grown carbon fibers (VGCF), and carbon nanotubes.

2. Binders

Binders such as polyvinylidene fluoride (PVDF) and styrene-butadiene rubber (SBR) hold active materials and conductive agents together, ensuring strong adhesion to current collectors.

3. Current Collectors

Aluminum foil is used as the positive current collector for its stability at higher voltages.

Copper foil is used on the negative side due to its superior conductivity.

Nickel tabs and aluminum tabs serve as terminals and maintain external circuit connections.

Conclusion

Understanding the materials used in Li-ion batteries is key to appreciating their design, performance, and safety. From high-voltage cathodes to conductive separators and precise electrolyte systems, every component plays a critical role in shaping battery efficiency and durability.
