We’re introducing our next-generation carbon–zinc (C–Zn) SERP Battery stack. Built on soil-based galvanic energy harvesting, the new configuration delivers more stable output and improved energy budgets for low-power electronics, while preserving our core advantages: no wiring, no solar panels, and near-zero maintenance. *** What Changes with Carbon–Zinc Cathode kinetics: Porous carbon (graphitic) cathodes support oxygen-reduction reactions in aerated soils, reducing polarization vs. metal–metal pairs under similar conditions. Lower internal loss: Optimized electrode geometry and ionic path length improve effective series resistance in typical field deployments. Compatibility: Fully compatible with our DC–DC + buffer architecture; drop-in for LoRa nodes and short-burst video modules. *** System Architecture (unchanged, proven) C–Zn soil cell(s) → high-efficiency step‑up DC‑DC → rechargeable buffer cell → device (LoRa / IR / camera)
Operating Conditions (engineering guidance) Soil moisture: Works across a wide range; best stability in consistently moist, aerated soils. Temperature: Designed for sub‑zero to high‑summer conditions; buffer sizing recommended for extremes. Placement: Favor shallow, oxygenated layers for the carbon cathode; ensure robust mechanical anchoring for zinc anode.
Target lifespan: up to 3 years under a typical low-duty cycle (e.g., LoRa uplink every 15–30 min; 5–12 short video clips/day), ambient −15…+31 °C, and soil conductivity ≥ 0.2 mS/cm. Field-validated in Estonia
Sustainability Recyclable zinc anode and carbon cathode; low material mass per node. Ground-level installation; minimal surface footprint; retrieval at end‑of‑life. Pilot with C–Zn now (10-node kits for integrators and research groups). DM for specs, pricing, and timelines. —
