“…The water absorption peak intensity at ca. 3500 cm -1 increases with the aging time, and several absorption peaks in the range of 1500-800 cm -1 shift-change due to the structural deterioration of LiBOB 40,44 . It should be also noted that a very small water peak might be visible in the spectrum of the as-synthesized sample, since the measurement was not done in a protective atmosphere, so the sample was exposed to air for a minute.…”

Lithium bis(oxalate)borate, LiB(C 2 O 4 ) 2 (LiBOB), is one of the most important electrolyte additives for Li-ion batteries (LIBs) due to its numerous advantages such as thermal stability, good solubility in organic solvents, high conductivity, and low cost as well as providing safer operations with superior electrochemical performance compared to conventional electrolyte combinations. However, the use of LiBOB is limited due to slight instability issues under ambient conditions that might require extra purification steps and might result in poorer performances in real systems. Here, we address some of these issues and report the high purity water free LiBOB synthesized with fewer processing steps employing lithium carbonate, oxalic acid, and boric acid as lowcost starting materials, and via ceramic processing methods under protective atmosphere. The physical and chemical characterizations of both anhydrous and monohydrate phases are performed with X-ray powder diffraction (XRPD), Fourier-transform infra-red spectroscopy (FTIR), Raman spectroscopy and scanning electron microscopy (SEM) analyses to determine the degree of the purity and the formation of impurities like LiBOB.H 2 O, HBO 2 and Li 2 C 2 O 4 as a result of the aging investigations performed. Differential thermal analysis (DTA) is applied to determine the optimum synthesis conditions for anhydrous LiBOB and to analyze the water loss and the decomposition of LiBOB.H 2 O. Aging experiments with the water free LiBOB are carried out to evaluate the effect of humidity in the phase changes and resulting impurities under various conditions. The detrimental effect of even slightest humidity conditions is shown, and protective measures during and after the synthesis of LiBOB are discussed. Anhydrous LiBOB could be widely used as an electrolyte additive to improve the overall electrochemical performances for LIBs through development of a protective solid electrolyte interphase (SEI) on the surface of high voltage cathodes and bringing about superior electrochemical properties with increased cycling stability, rate capability and coulombic efficiency, if synthesized, purified, and handled properly before use in real electrochemical systems.

Electrolyte plays a key role in lithium-ion battery system.Safety and reliability factor was the main background of the development of solid polymer electrolyte as a substitute the conventional electrolyte in liquid form. Preparation and characterisation of a polymer electrolyte system based on lithium bis(oxalato) borate or LiBOB salt and PVdF as the host matrix has been performed. LiBOBsalt and PVdFpolymer were dissolved in DMAC solvent followed bysolid polymer electrolyte forming by means of doctor blade method. The membranes obtained were characterised by FT-IR, XRD, and EIS. It was shown that the electrolyte exhibited higher room ionic conductivity with the increase of salt concentration, with highest conductivity value of 1.22 × 10 −6 Scm −1 for 70% LiBOB concentration.

POTENSI RISET DAN PENGEMBANGAN FePO4 DARI BAHAN BAKU LOKAL Fe2O3 DI INDONESIA

Riset dan pengembangan baterai lithium mulai banyak dilakukan di Indonesia sejak awal dekade 2000-an. Diantara salah satu material yang dikembangkan adalah bahan aktif katoda LiFePO4,dengan harapan bahwa seluruh bahan baku pembuatan LiFePO4 diperoleh dari sumberdaya lokal. Sumber-sumber bahan baku LiFePO4 sendiri adalah LiOH atau LiOH.H2O atau Li2CO3 atau CH3COOLi sebagai sumber Li, Fe2O3 sebagai sumber Fe, dan H3PO4 sebagai sumber PO43-. Diantara berbagai sumber bahan baku tersebut, Fe2O3 dan H3PO4 dapat diperoleh dari dalam negeri, namun sumber lithium masih harus impor. Oleh sebab itu, produksi LiFePO4 kedepannya tidak dapat 100% menggunakan bahan baku lokal. Namun, terdapat satu cara yang dapat dilakukan agar menggunakan 100% bahan baku lokal, yaitu pengembangan FePO4. FePO4 ini nantinya berpotensi untuk diproduksi dan diekspor sebagai bahan baku pembuatan LiFePO4. Disamping itu, FePO4 juga memiliki nilai tambah lain sebagai bahan pelapis pencegah oksidasi pada permukaan logam. Oleh sebab itu, material ini cukup strategis untuk dikembangkan di Indonesia.
