Oct 13, 2025 by wbrum.org 0 views

Introduction

The world is shifting towards renewable energy sources, and battery technology plays a crucial role in this transition. Among the various battery technologies, aluminum-ion batteries (ALBs) have gained significant attention due to their high energy and capacity density, along with relatively low production costs. However, the use of liquid electrolytes in ALBs poses a significant risk to both human health and the environment. This is because liquid electrolytes are generally concentrated inorganic compounds that can cause leakage due to high corrosion rates in aluminum metals.

The Need for Sustainable Battery Technology

The increasing demand for energy storage solutions has led to the development of various battery technologies. However, the use of liquid electrolytes in ALBs has raised concerns about their safety and environmental impact. The leakage of liquid electrolytes can contaminate soil and water, posing a significant threat to ecosystems. Moreover, the use of hazardous chemicals in battery production can harm human health. Therefore, there is a pressing need for sustainable battery technology that can address these concerns.

Carboxymethyl Cellulose (CMC) as a Sustainable Alternative

Carboxymethyl Cellulose (CMC) is a biodegradable and non-toxic polymer that has been widely used in various applications, including food, pharmaceuticals, and cosmetics. Its high ionic conductivity, good thermal stability, and environmentally friendly nature make it an ideal candidate for replacing liquid electrolytes in ALBs. CMC can form hydrogels, which can hold liquid electrolytes in their network, preventing leakage and ensuring a safer and more efficient battery.

Starfruit Electrolytes: A Natural and Sustainable Solution

Starfruit (Averrhoa carambola) is a tropical fruit that has been used in traditional medicine for centuries. Its filtrate has been shown to have high ionic conductivity, making it an excellent natural electrolyte solution. The use of starfruit electrolytes in ALBs can provide a sustainable and environmentally friendly solution, reducing the dependence on hazardous chemicals.

Methodology

The main ingredients used in this study are:

Carboxymethyl Cellulose (CMC): Acts as a binder and forming hydrogel.
Wuluh starfruit filtrate: Functions as an electrolyte solution.
Ethylene Glycol: Used as a plasticizer to increase hydrogel flexibility.

The method adopted in the process of making hydrogels includes gelatinization and plastization methods.

Research Results

From the research conducted, the optimal condition was found with a combination of 2% CMC added with 15 ml of ethylene glycol plasticizer, as well as the ratio of electrolyte starfruit filtrate to the CMC solution of 1:1. In this condition, the resulting hydrogel shows the highest ion conductivity of 1,286 x 10^-2 up to cm. In addition, the battery produced has a voltage of 1,4267 V and a specific capacity of 1,363 mAh/gram.

Analysis and Benefits

The use of carboxymethyl cellulose as the main ingredient in making hydrogels in aluminum-ion batteries shows great potential in improving battery performance while reducing the negative environmental impact of the use of traditional liquid electrolytes. The combination of environmentally friendly materials such as starfruit filtrate and CMC not only guarantees the effectiveness of the battery, but also provides a sustainable solution.

Furthermore, this research opens the way for innovation in the field of safer and more efficient battery development, so that it can contribute to answering global energy challenges. With the application of this technology, we can reduce dependence on hazardous chemicals and improve the quality of life by providing cleaner and safer energy to use.

Conclusion
