CATL 70AH3.7V NCM Lithium-ion Prismatic Battery Cell

1. Primary Applications

• New Energy Passenger Car Traction Battery
  Core energy carrier for BEV, PHEV, and EREV. With 200–300 Wh/kg gravimetric energy density, NCM/NCA large‑format cells enable 800–1,000 km CLTC range, making them the mainstream choice for long‑range premium passenger cars.

• New Energy Commercial Vehicle & Construction Machinery Power
  Used in electric buses, heavy‑duty trucks, and construction machinery requiring high power output and fast energy replenishment. The high‑rate discharge capability handles heavy‑load climbing and frequent start‑stop, while fast‑charge support improves operational efficiency.

• Energy Storage System (ESS)
  Applied in grid frequency regulation/peak shaving, telecom base station backup, and C&I storage. High volumetric energy density (~500–600 Wh/L) gives a significant advantage in space‑constrained storage cabinets. Some 40135 large cylindrical NCM cells were already adopted for high‑reliability ESS projects in 2026.

• 48V Micro‑Hybrid System
  Powers start‑stop, regenerative braking, and assisted driving in ICE vehicles. NCM large‑format cells fit the tight engine‑bay space thanks to high power density and compact form factor.

• Electric Two‑Wheelers & Light Mobility Devices
  High‑capacity NCM large‑format cells (e.g., 72V90Ah, 76V96Ah) have been mass‑deployed in high‑performance e‑motorcycles and long‑range delivery scooters, easily exceeding 300 km range with fast‑charge capability.

• UAV & eVTOL (Electric Vertical Take‑Off and Landing)
  Flight vehicles are extremely weight‑sensitive; NCM’s high energy density (≥230 Wh/kg) is key to long endurance. In 2026, leading manufacturers have listed large‑format NCM cells as eVTOL‑ready products for the low‑altitude economy.

• Electric Ships & Yachts
  Yachts and hydrofoils demand both light weight and high power. NCM large‑format cells simultaneously deliver long range and high current output.

• Intelligent Robotics
  Service robots and humanoid robots need compact, high‑power battery units. NCM large‑format cells offer the ideal combination of small size and excellent rate performance.

• Starter & Backup Power Supply
  As a lead‑acid replacement, NCM large‑format cells provide greater cranking current and longer backup time. Widely used in automotive jump starter power banks and data center backup systems.

3. Technical Scope of Suitability

• Scenarios Requiring High Gravimetric Energy Density (200–300 Wh/kg at Cell Level) for Lightweight Design
  Ideal when every kilogram counts, such as in aviation, high‑performance EVs, and portable devices.

• Operating Temperature Range: -20°C to 60°C; Discharge Efficiency at -30°C ~70%, Superior to LFP
  Performs acceptably in cold climates, though active heating may still be required for charging below 0°C.

• High‑Frequency Usage Demanding 3C–10C+ Fast Charging
  Suitable for ride‑hailing, taxi fleets, and long‑haul logistics where downtime must be minimized.

• High Peak Power Applications
  Covers scenarios like heavy‑load hill climbing, aircraft take‑off, and robotic burst movements that require brief but intense power delivery.

• Space‑Constrained Battery Pack with High Range Requirements
  Volumetric energy density of ~500–600 Wh/L allows larger capacity in the same packaging volume, critical for sleek vehicle designs.

• Moderate‑to‑High Cycle Duty (Typical 1,000–3,000 Cycles), Requiring Active Thermal Management (Liquid/Air Cooling)
  Cycle life is sufficient for most automotive and industrial applications, but a robust BMS and cooling system are mandatory to manage heat and ensure safety.

• Requires Automotive‑Grade BMS for Overvoltage Protection (4.20 V Cut‑Off), Thermal Runaway Monitoring & Cell Balancing
  Essential to prevent overcharge, detect early signs of thermal runaway, and maintain cell‑to‑cell consistency in large‑format packs.

• Not Ideal for Cost‑Highly‑Sensitive & Extreme Safety‑Margin Scenarios That Can Accept Lower Energy Density
  For example, certain stationary ESS or entry‑level vehicles where initial purchase price and ultimate safety outweigh the need for maximum range—LFP is generally preferred in those cases.
