LG E78 3.7V 78Ah NMC Lithium Polymer Pouch Cell Rechargeable Battery

Our NCM 523 pouch cell is optimized for stationary energy storage with 5,000+ cycles at 80% DOD and 170Wh/kg energy density. The 50Ah cell (250x120x8mm) features a tabless design with laser-etched current collectors, reducing internal resistance to ≤0.8mΩ. The IP65-rated casing protects against dust and water spray, while the cobalt-manganese-stabilized cathode ensures linear capacity fade (<0.03% per cycle).

1. Grid-Level Economics

Achieves $180/kWh system cost, competing with LFP for commercial peak shaving.

Second-life compatibility: Repurposes into grid storage after EV use (60% residual capacity).

2. Smart Thermal Management

Serpentine cooling channels enable <2°C temperature variation across 1,000-cell arrays.

Compatible with 3M™ Novec™ fire suppression fluid for 1MWh+ container systems.

3. Regulatory Compliance

Meets UL 9540A and IEC 62619 for North American and European grid projects.

LoRaWAN-enabled cells support remote monitoring of 10,000+ unit installations.

Passenger cars: NCM pouch cells are widely used in electric passenger cars due to their relatively high energy density. They can provide a sufficient driving range for daily commuting and long-distance trips. For example, many popular electric vehicle models use NCM pouch cells to power their electric drivetrains, enabling efficient acceleration and smooth operation.

Commercial vehicles: Such as electric buses and delivery vans. The high energy density and relatively lightweight nature of NCM pouch cells help these vehicles to carry more cargo or passengers while maintaining an acceptable range. They also contribute to reducing operating costs by replacing traditional fossil fuel-powered engines.

2. Energy storage systems (ESS)

Grid-scale energy storage: NCM pouch cells can be integrated into large-scale battery energy storage systems connected to the electrical grid. These systems help to balance the supply and demand of electricity, store excess energy generated from renewable sources (such as solar and wind) during peak production times, and release it when demand is high. This improves the stability and reliability of the grid.

Residential and commercial energy storage: In homes and businesses, NCM pouch cell-based energy storage systems can store electricity generated from on-site solar panels or purchased during off-peak hours. This stored energy can be used during peak demand periods or power outages, reducing electricity bills and providing backup power.
