Description

WIDE TEMPERATURE RANGE 21700 TABLEtS LITHIUM-ION BATTERY

COMMERCIAL GRADE · PRODUCTION

Product Overview
Designed for severe environmental deployment and high-frequency power demands, this high-performance tabless lithium ion battery features an innovative cylindrical configuration optimized to eliminate standard current collectors. Implementing a specialized wide temperature range 21700 architecture, the 5.0Ah 3.6V cell utilizes an advanced NCM silicon oxide chemistry platform (Nickel Cobalt Manganese / Graphite + Silicon Oxide) to yield low impedance metrics (≤3.5 mΩ). This structural configuration supports a secure 15C high rate continuous discharge profile with high energy density parameters (≥250 Wh/kg). Its heavy-duty tabless engineering path balances internal heat profiles safely under continuous loads, supplying reliable, high-power electron flow down to cold sub-zero environments, acting as the definitive power baseline for modern electric vehicle powertrains, portable tools, and aerospace engineering tasks.
