Our in-stock 1P nickel plated steel strip is independently cold-rolled, electroplated and inspected by DZX, specially tailored as standard conductive connecting accessory for series-parallel assembly of 18650 cylindrical lithium battery packs. We adopt low-carbon deep-drawing steel as substrate and adopt our proprietary uniform low-stress continuous nickel plating process, forming a dense, pore-free nickel protective layer tightly combined with steel base. The standard 1P single-row layout perfectly matches the terminal spacing of single strings of 18650 cells, supporting direct spot welding without secondary cutting for mass battery assembly workshops, DIY energy storage packs and power tool battery production lines.

Battery pack manufacturers have long faced three conflicting material dilemmas when assembling 18650 cells. Bare steel strips carry ultra-low purchase costs but oxidize rapidly in humid battery workshops, generating high-resistance iron oxide that causes cold welding, local overheating and hidden thermal runaway risks inside sealed battery modules. Pure nickel strips deliver stable conductivity and anti-corrosion performance yet cost 3–5 times higher than nickel-plated steel; their soft texture easily deforms under vehicle vibration or assembly extrusion, leading to loose welding joints after long-term cycling. Low-grade ordinary nickel-plated steel strips feature uneven plating thickness, pinholes and weak metal bonding, which peel off during bending or stamping, while non-standard widths require manual trimming, wasting labor and reducing production efficiency. DZX ready-stock 1P nickel plated steel strip solves all these drawbacks simultaneously. The steel core provides high tensile strength to resist vibration creep, the uniform nickel coating blocks electrolyte vapor and air oxidation, and standardized 1P single-row specifications realize one-step welding matching 18650 cell layout to cut pre-processing labor costs sharply.

We operate all production procedures in-house, covering steel cold rolling, surface activation cleaning, reel-to-reel continuous nickel electroplating, stress relief annealing and precision fixed-width slitting, without outsourcing plating or cutting links to third-party factories. Every finished coil and pre-cut 1P strip undergoes full offline testing for plating uniformity, tensile hardness, neutral salt fog resistance and spot welding ductility before warehousing as ready stock. All battery accessories comply with RoHS, REACH and IATF 16949 lithium battery industry standards, eliminating safety hazards caused by unqualified connecting materials. Real-time optical thickness detectors run on all production lines to lock nickel coating thickness, steel hardness and dimensional tolerance within ultra-narrow fluctuation ranges, ensuring consistent welding and conductive performance for all in-stock batches.

This ready-stock 1P nickel plated steel strip serves as mainstream standard battery accessory covering three booming downstream markets driven by portable energy storage and electric mobility upgrading.

First, electric two-wheeler 18650 battery packs. Single-row 1P nickel tape connects individual strings of 18650 cells for scooter, balance bike and e-bike battery modules; standardized sizes support automated spot welding assembly lines to improve daily output.

Second, portable power & power tool lithium batteries. Power banks, garden power tools, handheld drills and outdoor portable energy storage all adopt 18650 cylindrical cells; 1P in-stock nickel strips meet small-batch assembly and DIY pack production demands with zero waiting lead time.

Third, small household energy storage & backup power supplies. Indoor solar energy storage modules, UPS emergency power and monitoring equipment backup batteries rely on 1P nickel steel strips for stable single-string cell interconnection, resisting temperature fluctuations and indoor humid environments.

Global demand for 18650 cylindrical lithium batteries maintains steady growth, continuously lifting market demand for matched 1P nickel plated steel connecting strips. Industry data shows the annual compound growth rate of nickel steel battery accessories for cylindrical cells reaches 12.9% from 2026 to 2030. Skyrocketing pure nickel raw material prices push most medium-volume battery manufacturers to switch to cost-effective nickel-plated steel accessories, while factories with small-batch, multi-order production demands prioritize ready-stock nickel strips to avoid long custom production cycles. Mid-to-small battery assembly plants gradually replace irregular low-grade nickel steel and expensive pure nickel tape with DZX in-stock 1P nickel plated steel strips, shortening delivery cycles, reducing welding scrap rates and lowering overall raw material procurement costs.

We collect thousands of on-site assembly feedback from lithium battery manufacturers cooperating with generic material suppliers, summarizing five core quality and production defects brought by non-DZX nickel steel accessories:

1. Rapid rust of bare steel connecting strips: Within 1–2 weeks of warehouse storage or humid battery workshop environment, red iron oxide covers strip surfaces, destroying spot welding joints and triggering open-circuit overheating failures in finished 18650 packs.

2. Long lead time for non-standard customized nickel tape: Most suppliers only accept large-batch customized orders without ready inventory; small-batch customers wait 7–15 days for production, delaying battery delivery schedules.

3. Uneven nickel plating on cheap processed steel strips: Discontinuous batch electroplating creates pinholes and ultra-thin coating areas; neutral salt fog testing fails within 24 hours, and corrosive media penetrates steel base to form hidden rust points inside sealed battery packs.

4. Nickel coating peeling during bending and spot welding: Suppliers skipping pre-plating surface micro-activation produce strips with weak metallurgical bonding between nickel and steel. Coating flakes off after repeated folding, exposing bare steel that oxidizes quickly to increase contact resistance.

5. Unstable batch dimensional consistency from small-scale processors: Manual random sampling inspection leads to wide fluctuations in strip width and plating thickness between batches. Battery factories must frequently adjust spot welding machine current parameters, raising labor testing costs and finished battery scrap rates.

All these costly production and battery reliability risks can be fully eliminated by adopting DZX standardized in-stock 1P nickel plated steel connecting strips, supported by our full-process closed-loop quality monitoring system and sufficient permanent inventory reserves.

We break down key technical metrics directly determining 18650 battery welding yield, conductive stability and anti-rust service life for battery design and procurement engineers:

Nickel Coating Thickness: Adjustable range 0.5μm–5μm; 1μm standard for portable power bank and power tool 18650 packs, 3μm recommended for e-bike and outdoor energy storage battery modules. Too thin coating fails salt fog anti-corrosion testing; overly thick nickel raises overall contact resistance and weakens stamping ductility.

1P Standard Dimensional Specification: Ready-stock mainstream sizes 0.12/0.15/0.18/0.2mm thickness × 6/8/10mm width, perfectly matching single-row terminal spacing of standard 18650 cylindrical cells, no secondary cutting required.

Tensile Strength & Elongation: Standard soft annealed steel base elongation ≥25%, tensile strength 380–450MPa for flexible cell interconnection; hard temper tensile strength 500–620MPa for rigid main busbar terminals.

Neutral Salt Spray Resistance: Standard DZX in-stock nickel steel strips pass 72-hour salt fog testing without red rust; customized heavy anti-corrosion grades support 200-hour salt mist compliance for coastal outdoor battery equipment.

Steel Base Purity: Low-carbon deep-drawing steel with ultra-low impurity content, minimizing spot welding electrode abrasion during mass 18650 pack assembly.

Dimensional Tolerance: Thickness tolerance ±0.002mm, width tolerance ±0.02mm, burr-free slit edges to prevent puncturing 18650 battery cell insulating diaphragms during assembly.
