1414 Degrees (ASX:14D) said its SiNTL silicon nanoparticle anode cells exceeded 550 milliampere-hours per gram across all tested configurations, with optimized formulations recording above 600 milliampere-hours per gram on initial cycles, according to a Wednesday Australian bourse filing.

SiNTL was designed as a drop-in upgrade requiring no retooling or process redesign, targeting demanding applications including large drones and unmanned aerial vehicles, electric vehicles, military systems, and industrial power tools, the company said.

The company said the milestone represents more than 50% higher than conventional graphite anodes and about 20% above current commercial silicon-enhanced anode benchmarks.

Carbon-enhanced SiNTL silicon anode formulations are in development to sustain 600-plus milliampere-hours per gram across a wider range of charge and discharge rates, with results expected in the near term, per the filing.

The company's shares fell past 1% in recent Wednesday trade.
