Evaluasi ekstrak daun karamunting sebagai inhibitor korosi aluminium dalam larutan asam dan basa dipelajari dengan menggunakan uji perendaman. Metode gravimetri digunakan untuk menghitung laju korosi aluminium dengan dan tanpa inhibitor. Hasil penelitian menunjukkan bahwa senyawa yang terkandung dalam ekstrak daun karamunting merupakan senyawa heteroatom oksigen dan memilki ikatan rangkap. Berdasarkan hasil studi permukaan dengan Scanning Electron Microscopy (SEM), tingkat kerusakan aluminium dengan penambahan inhibitor lebih rendah dibandingkan dengan tanpa inhibitor. Penambahan inhibitor dari ekstrak daun karamunting dapat mengurangi laju korosi aluminium. Efisiensi penggunaan inhibitor diperoleh 73,66% pada larutan NaOH dan 80,78% pada larutan HCl pada variabel konsentrasi inhibitor dan waktu perendaman tertinggi. Model regresi linier berganda digunakan pula dalam penelitian ini untuk memprediksi laju korosi aluminium. Kata kunci: aluminium, ekstrak alami, inhibitor, korosi, regresi linier

Summary In order to explore the discharge characteristics of aluminum‐air battery and find out the best discharge performance of aluminum‐air battery under the optimum working conditions, this paper studies discharge performances of an aluminum‐air battery under various ambient temperature and battery discharge conditions. The relationship between the temperature rise of the battery electrolyte and the discharge current density was studied by an experimental method. Effects of the electrolyte concentration and the ambient temperature on the battery discharge voltage were investigated. In addition, a novel method for calculating the efficiency of the aluminum‐air battery was proposed. Results show that the temperature of the aluminum‐air battery electrolyte gradually increases as its discharge current density increases and the electrolyte temperature rise could reach as high as 10°C after 60 minutes with a constant 35 mA cm−2 discharge current density. The specific energy and the specific capacity of the aluminum‐air battery first increase and then decrease as the current density increases. When the current density is 25 mA cm−2, the specific energy has a peak of 3105 Wh kg−1 for the condition of the chamber temperature 40°C and the electrolyte concentration 2 mol L−1 (2 M), while the specific capacity has a peak of 2207 Ah kg−1; furthermore, its efficiencies under various conditions increase first with the current density, reach a peak range of 19.6% to approximately 36% at 25 mA cm−2, and then decrease. These experimental results could be used as a technical guidance for the optimization in thermal management designs of the aluminum‐air battery under various operating conditions.

Summary Due to lack of systematic research on open‐circuit voltage (OCV) and electrolyte temperature rise characteristics of aluminum air battery, in order to explore the influential factors on the OCV and electrolyte temperature rise of aluminum air battery, in this paper, for the first time, we studied the effects of different ambient temperature conditions, different concentrations of NaOH and KOH electrolyte, and pure aluminum and aluminum alloy on the OCV and electrolyte temperature rise of aluminum air battery. Results show that the OCV of aluminum air battery is obviously affected by ambient temperature conditions, electrolyte concentration, and different anode materials. The OCV range is 1.5 to 1.8 V at 0°C under different KOH‐electrolyte concentrations when aluminum alloy is used as anode material; with the increase of ambient temperature, the OCV will rise, and the range is 1.8 to 1.95 V. The working process of aluminum air battery is accompanied by the phenomenon of heat release, and the temperature rise range of electrolyte will not exceed 7°C when aluminum alloy is used as the anode material; however, the highest temperature of the electrolyte can reach 100°C when pure aluminum is used as the negative electrode material. The results of this study will provide theoretical guidance for designing aluminum air batteries and identifying their optimal operating conditions.
