Abstract: DELA CRUZ, KENNETH LEWIS A. and SALARDA, MAR JHUN P. Design and Construction of Waste Coffee Ground Battery. Undergraduate Design Project. Bachelor of Science in Electrical Engineering. Cavite State University, Indang, Cavite. June 2019. Adviser: Engr. Ronald P. Perla. The study was conducted from January 2019 to April 2019 inside Cavite State University — Don Severino de las Alas Campus, Indang, Cavite. The main objective was to design and construct a 12 V battery with the use of waste coffee ground as electrolyte. It specifically aimed to: (1) collect waste coffee grounds and test for its pH level; (2) combine salt, calamansi and vinegar to the collected waste coffee grounds and test for its pH level; (3) create cell with different pair of electrodes immersed into waste coffee grounds and other electrolytes and measure the open-circuit voltages and short-circuit currents; design and construct the battery system based on initial tests; (4) test and evaluate the prototype constructed; and (5) conduct material cost computation. The battery consists of eight cells connected in series. Each cell contains a magnesium rod and a fabricated carbon plate. The open circuit voltage of the battery has values ranging from 12.7 V to 13.2 V. The waste coffee ground battery was tested and evaluated under a 300-ohm resistor. The computed storage capacity of the battery is 124.5 mAh. The total cost of the study was P 11,306.
