The growing demand for sustainable, low-cost, and biodegradable energy storage has motivated research into bio-inspired materials. This paper introduces the Coconot Battery , a novel electrochemical cell that leverages the natural properties of the coconut endosperm (solid kernel), coconut water (liquid endosperm), and husk fibers. By using modified coconut components as electrolyte and separator matrices, the Coconot Battery offers a renewable, non-toxic alternative to conventional lithium-ion systems for low-power applications. Experimental projections indicate an energy density of 40–60 Wh/kg, stable cycling over 300 charge–discharge cycles, and complete compostability after end-of-life.
"What the hell is that, Lieutenant?" the crew chief shouted over the noise.
Concept inspired by traditional coconut-based technologies and recent advances in biopolymer electrolytes.
6 coconuts. 6 improvised electrolytic cells. Approximately 5 to 6 Volts. Maybe 400 milliamps.
He hooked the final leads to the radio’s power input. The display flickered.
For the negative, he looked at the fragmentation grenade on his vest. He didn't pull the pin; instead, he unscrewed the base of the grenade’s fuse mechanism. The safety lever spring was made of high-grade steel, but the casing that held the explosive compound had a zinc alloy plating to prevent corrosion in humid climates.
Aris looked back at the bubbling fruit. He smiled, exhausted.
