An improved carbonate co-precipitation method for the preparation of spherical Li[Ni1/3Co1/3Mn1/3]O2 cathode material

Thermal treatment process for the recovery of valuable metals from spent lithium-ion batteries

“…The light weight and reliable lithium ion batteries have been widely used in portable electronic devices (Zhang et al, 2009). Currently, the cheap and safe layered cathode materials LiMO 2 (M = Ni, Co and Mn) are one of the most widely used commercial cathode materials in the market (Liu et al, 2012).…”

Influence of Li source on tap density and high rate cycling performance of spherical Li[Ni1/3Co1/3Mn1/3]O2 for advanced lithium-ion batteries

“…4c and d. Previous reports by Ren et al [20] and Cheralathan et al [32] have shown that the uniform particle distribution of cathode materials could lead to the uniform depth of charge (DOC) of each particle, which increases the utilization of the material to enhance the overall battery performance. In addition, it is shown Table 1 ; meanwhile, this value is also higher than most Li[Ni 1/3 Co 1/3 Mn 1/3 ]O 2 materials prepared by carbonate co-precipitation method in previous reports [21][22][23]. The higher tap density of sample obtained from LiOH⋅H 2 O can be attributed to the closer packing properties of the spherical particles compared to other samples [33].…”

“…Li[Ni 1/3 Co 1/3 Mn 1/3 ]O 2 can be prepared using different methods: solid-state reaction [16], sol-gel process [17], co-precipitation method [18][19][20][21][22][23][24], microwave method [25], rheological phase method [26] and microemulsion method [27], etc. Among these methods, co-precipitation is recognized as a promising production technique in homogeneously mixing all reagents at atomic or molecular level, allowing careful control of the stoichiometric amount, morphology and particle size distribution of the final product Li[Ni 1/3 Co 1/3 Mn 1/3 ]O 2 [18,19].…”

Synthetic optimization of nanostructured Li[Ni1/3Mn1/3Co1/3]O2 cathode material prepared by hydroxide coprecipitation at 273K

“…However, the toxicity and high cost of cobalt prohibit its further applications in large scale and price sensitive batteries, such as those for electric vehicles [2,3]. In recent years, Li[Ni 1/3 Co 1/3 Mn 1/3 ]O 2 is considered as a promising alternative to LiCoO 2 because it has many advantages such as high discharge capacity, good cycle stability, low cost and safety [4,5].…”
