Applications We're Actively Supplying Prototypes For

Stacked cells provide 10–60s hold-up in servers and edge devices to flush data to flash during power events — clean delivery via ultra-low ESR.

Bridge 10–60s outages or voltage dips in smart meters, routers, cameras, alarms, and access controls — sustaining data logging, communication, and system stability without resets

Store harvested energy and deliver pulses (50–500 mA typical, up to several amps for boosted modes) for LoRaWAN, NB-IoT, Zigbee, or BLE — extending life in remote monitoring.

Quick several-amp peaks for handhelds, scanners, and telemetry in harsh conditions — minimal voltage drop, reliable performance.

Volfpack Energy

We're a Sri Lankan startup that started with millifarad-level prototypes and has now scaled to producing graphene pouch cells in 1F, 5F, 30F, 50F, and 100F variants (2.7V).

These compact powerhouses deliver seconds-fast charge/discharge, ultra-low resistance (<1 mΩ), over 1 million cycles, and zero heavy metals. We're actively supplying prototype batches and evaluation samples to engineers, partners, and early adopters.
