Design, Testing, and Construction of an Alternative Zn-Cu Electrolytic Cell Battery

2019

The world needs more energy to meet socio-economic development requirements and enhance global living standards to continue to improve (BP, 2019; IPCC, 2012). In 2018, the global energy demand rose by 2.3%, the fastest in the last decade (IEA, 2019). By 2040 it is forecasted that various sources of energy will increase and still be widely used including the nonrenewables such as coal, gas, and oil (BP, 2019). Around 1.1 billion people (14% of the global population) have no access to electricity (IEA, 2017). Many of those without access are found in rural areas, and more than 95% of those living without electricity are in countries in developing Asia and sub-Saharan Africa (ibid). To date, several communities still found on off-grid and don't have access to electricity (ibid) to light their homes or power, even small devices. In the Philippines, an estimated offgrid demand of 209.86 MW in 2015 was recorded (ADB, 2018). The need for energy to even light the homes of the isolated c...

Performance of Zn-Cu and Al-Cu Electrodes in Seawater Battery at Different Distance and Surface Area

International Journal of Renewable Energy Research, 2017

Seawater battery is one of the green electricity sources to fulfilled energy needs for several equipments, especially in the coastal area and fishing activities. The application of this technology is still limited because of the high cost in the electrode production. This study was analyzed the performance of Zn-Cu and Al-Cu electrode as cheap material to generate electricity from sea water in the different distance and surface area. The results shown zinc anode produced higher voltage and current than aluminium anode with number of 839 mV and 1.75 mA respectively. Increasing of surface area at the same distance will increase the current output for each materials. Distance of electrode affect to the current density, but it causes fluctuation at the voltage. Application of zinc anode with higher surface area and short distance will generate high voltage and current output in the salt water battery.

Seawater Battery with Al-Cu, Zn-Cu, Gal-Cu Electrodes for Fishing Lamp

2017

The key problem in application of seawater battery is lies on the expensive cost of anode material manufacture, especially for fishing activity. Seawater battery with common electrode such as Al-Cu, Zn-Cu, Gal-Cu are expected for selecting fixed lift net application through innovation of Light Emmitting Diode (LED) fishing lamp. This research is evaluated the performance of seawater battery with various common electrodes to drive LED lamp during discharge process. Laboratory experiment was conducted on December 2016 to January 2017, in order to measure potential and current output of aluminium (Al), zinc (Zn), and galvalume (Gal) anode of seawater battery without load and load condition. The results showed the zinc anode had the higher performance in term of voltage and current output than galvalume and alumunium anode. The maximum power output of zinc (704.17 mW) was not significantly different with galvalume (726.41 mW), nevertheless these have a significant different with alumini...

The electrical productivity of Arabica coffee grounds battery based on electrode distance and dryness level

Jurnal Riset dan Kajian Pendidikan Fisika

Bio-battery is an alternative natural energy source that utilizes organic compounds to generate electricity. This research uses coffee grounds as an environmentally friendly electrolyte paste. This study aims to identify and analyze the current and voltage produced by the bio batteries with the durability of bio batteries made from Arabica coffee grounds based on electrode distance and dryness level. The method used is a direct measurement of coffee grounds using copper (Cu) and zinc (Zn) as electrodes, further testing of the output current and voltage is carried out every 24 hours. The results showed that Arabica coffee grounds produce a maximum voltage of 1.01 V, a current of 0.49 mA and a power of 0.42 W. Based on these results, Arabica coffee grounds have the potential to be used as bio batteries.
