Overview

Our NCM 811 pouch cell sets a new benchmark for electric vehicle range with a superior energy density of 215Wh/kg. Featuring an 8:1:1 nickel-cobalt-manganese cathode and silicon-carbon composite anode, the cell delivers a nominal voltage of 3.75V and 25Ah capacity in a compact 150x80x4mm form factor.

NCM Pouch Cell

Key Features

1. Extended Range Technology

Powers 100kWh+ battery packs for premium EVs, achieving 850km WLTP range with 20% fewer cells than NCM 622.

Ultra-thin 4mm profile enables skateboard battery designs with <120mm total height.

2. Fast Charging Capability

Supports 5C charging (0-80% in 15 minutes) using liquid-cooled thermal management.

Pre-installed NTC thermistor ensures precise temperature control during high-rate charging.

3. Safety Reinforcement

Passes UN38.3 thermal abuse tests without ignition, featuring self-extinguishing electrolyte.

IP67-rated casing protects against dust and water ingress for outdoor use.
