Abstract

ABSTRAK. Studi mengenai struktur kristal suatu material sangat penting dalam mengetahui baik tidaknya material, terutama untuk aplikasi teknologi penyimpanan energi listrik seperti baterai ion litium. Semakin murni dan baik suatu struktur kristal material, maka semakin baik efisiensinya dalam menjadi bahan baku material katoda baterai. Tujuan dari penelitian ini adalah sintesis dan analisis karakteristik struktur kristal prekursor NMC811 oksalat (Ni0,8Mn0,1Co0,1C2O4) dari senyawa Mixed hydroxide precipitate atau MHP dengan presipitan asam oksalat. Sintesis prekursor NMC811 dilakukan dengan mereaksikan MHP (Ni 51,43% wt) dengan asam asetat agar diperoleh larutan nikel asetat. Sejumlah garam kobalt dan mangan ditambahkan kedalam larutan sehingga komposisi nikel:kobalt:mangan senilai 8:1:1. Endapan prekursor diperoleh dengan penambahan presipitan larutan asam oksalat. Endapan prekursor yang berhasil diisolasi dianalisis dengan X-ray diffractometer (XRD) untuk evaluasi struktur kristalnya. Berdasarkan analisis XRD MHP memiliki puncak difraksi yang kurang tajam dengan lebar pita yang relative besar sehingga menandakan bahwa MHP memiliki sifat kristal yang buruk. Sementara itu, Prekursor NMC811 oksalat memiliki puncak difraksi yang tajam. Hal ini membuktikan prekursor memiliki sifat kristal yang baik dengan kemurnian yang tinggi. Oleh karena itu, Prekursor NMC811 oksalat dengan bahan baku MHP dapat digunakan untuk bahan baku material katoda baterai ion litium tipe NMC811. ABSTRACT. The study of the crystal structure of a material is very important in knowing whether or not the material is good, especially for the application of electrical energy storage technology such as lithium ion batteries. The purer and better the crystal structure of a material, the better its efficiency in becoming a battery cathode raw material. The purpose of this study was to synthesize and analyze the characteristics of the crystal structure of the precursor NMC811 oxalate (Ni0,8Mn0,1Co0,1C2O4) from Mixed hydroxide precipitate or MHP with oxalic acid as a precipitate. NMC811 precursor was synthesized by reacting MHP (Ni 51.43% wt) with acetic acid to obtain a nickel acetate solution. A number of cobalt and manganese salts are added to the solution so that the nickel:cobalt:manganese composition is 8:1:1. The precursor precipitate was obtained by adding oxalic acid solution as a precipitate. The isolated precursor precipitate was analyzed by X-ray diffractometer (XRD) to evaluate its crystal structure. Based on XRD analysis, MHP has a diffraction peak that is less sharp with a relatively large bandwidth, indicating that MHP has poor crystalline properties. Meanwhile, NMC811 oxalate precursor has a sharp diffraction peak. This proves the precursor has good crystalline properties with high purity. Therefore, the NMC811 oxalate precursor with MHP raw material can be used as the cathode material for the lithium ion battery type NMC811.

Abstract

One of the most finest materials for lithium ion battery nowadays is lithium iron phosphate or LiFePO4. Lithium iron phosphate was synthesized with solid state reaction method  by  optimizing  the  variable  of  material  and  temperature.  The  variable  for calcination temperatures were 700oC, 800oC, and 900oC while the basic materials as Fe sources were Fe2O3 and FeSO4. Particles morphologies and quantity of crystal were investigated in details by X-ray diffraction analysis XRD. XRD imaging showed diffraction of nanoparticles LiFePO4 with crystal quantity 40,4% (800oC) and 59,1% (900oC) of materials Fe2O3,which the most quantity from other samples. Thus, chatode materials were made from LiFePO4 that synthesized at calcination temperatures 800oC and 900oC. In conclusion the material chatode from LiFePO4 that had been synthesized had so many impurities because it was hard to get single phase of nanoparticles LiFePO4 and need more improvement in optimizing the process condition for ideal chatode material.

Abstract

ABSTRAK. Morfologi material merupakan salah satu aspek yang berpengaruh pada kualitas material katoda baterai Li-ion atau LIBs, salah satunya material katoda LiNi0,8Mn0,1Co0,1O2 atau NMC811. Semakin baik distribusi ukuran dan butiran partikel, maka semakin baik pula kualitas dari produk akhir NMC811. Penelitian ini bertujuan untuk sintesis dan analisis prekursor NMC811 (Ni0,8Mn0,1Co0,1C2O4) dengan mixed hydroxide precipitate atau MHP sebagai sumber Ni. Pada penelitian ini, prekursor NMC811 oksalat diperoleh dengan melarutkan MHP, CoSO4 dan MnSO4 pada larutan asam asetat. Larutan yang terbentuk dipresipitasi dengan asam oksalat sehingga membentuk endapan prekursor NMC811 oksalat. Instrumen pengujian SEM-EDX digunakan dalam mengevaluasi karakteristik morfologi sampel. Studi komparasi morfologi prekursor NMC811 dengan MHP juga dilakukan. prekursor Berdasarkan analisis komposisional menggunakan EDX, komposisi atom C, O, Mn, Co dan Ni secara berturut-turut 15,21±0.55%; 57,64±1.37%; 4,47±0.59%; 4,20±0.74%; dan18,48±1.71%. Sementara itu, analisis menggunakan SEM menunjukkan bahwa prekursor NMC811 memiliki bentuk dan ukuran partikel yang cenderung seragam dan lebih kompak dibandingkan MHP yang memiliki bentuk dan ukuran yang lebih bervariasi. Sintesis awal NMC811 dengan presipitan asam oksalat dapat meningkatkan keseragaman morfologi yang baik, sehingga nantinya dapat dihasilkan produk akhir NMC811 yang baik pula.  ABSTRACT. Material morphology is one aspect that affects the quality of the cathode material for Li-ion batteries or LIBs, one of which is LiNi0,8Mn0,1Co0,1O2 or NMC811 cathode materials. The better the particle size and grain distribution, the better the quality of the final NMC811 product. This study aimed to synthesize and analyze the precursor of NMC811 (Ni0,8Mn0,1Co0,1C2O4) with mixed hydroxide precipitate or MHP as the source of Ni. In this study, NMC811 oxalate precursor was obtained by dissolving MHP, CoSO4 and MnSO4 in acetic acid or lactic acid solution. The solution formed was precipitated with oxalic acid to form a precursor precipitate of NMC811 oxalate. The SEM-EDX test instrument was used to evaluate the morphological characteristics of the samples. A comparative study of the morphology of the NMC811 precursor with MHP was also carried out. precursors Based on the compositional analysis using EDX, the atomic compositions of C, O, Mn, Co and Ni were 15.21±0.55%, respectively; 57.64±1.37%; 4.47±0.59%; 4.20±0.74%; and 18.48±1.71%. Meanwhile, analysis using SEM showed that the NMC811 precursor had a particle shape and size that tended to be uniform and more compact than MHP which had a more varied shape and size. The initial synthesis of NMC811 with oxalic acid precipitant can improve the good morphological uniformity, so that later, a good final product of NMC811 can be produced.
