Electrochemical and cycling performance of neodymium (Nd3+) doped LiNiPO4 cathode materials for high voltage lithium-ion batteries

Plasma-enhanced atomic layer deposition of nickel and cobalt phosphate for lithium ion batteries

“…6 However, although some functional nickel-and/or cobalt phosphate electrodes have been reported, these are still scarce as both materials suffer from various issues such as instability (of both the electrode and its interface with the electrolyte) at these high potentials and poor electronic conductivity. Various possible solutions have been proposed in the form of surface coatings, 7 doping 8,9 or enhanced synthesis methods, 10 but more research is needed in order to commercialize these electrode materials.…”

The role of metal substitutions in the development of Li batteries, part I: cathodes

“…Mg 2+ substitution has been shown to increase structural stability, 410 while Nd 3+ substitution was able to achieve a capacity of 95 mA h g À1 at 0.1C and retained 85% capacity after 50 cycles at 2C. 411 Recently, Co-substituted LNP nanosheets were able to be cycled for 200 cycles at 0.1C with 98% capacity retention and an initial reversible capacity of 133 mA h g À1 at that rate using an LNP/ Li 4 Ti 5 O 12 full cell with solid polymer electrolyte. 412 Thus, it appears through structural control and metal substitution that LNP may be realized as a high-energy cathode material if combined with a highly stable solid electrolyte.…”

Phosphorus‐Based Materials for High‐Performance Alkaline Metal Ion Batteries: Progress and Prospect

“…Besides LiFePO 4 , other phosphate-based materials such as LiMnPO 4, [121,122] LiCoPO 4, [123,124] LiNiPO 4, [125][126][127] and Li 3 V 2 (PO 4 ) 3 [128][129][130] have received research attention due to the high operating voltages that can provide higher energy densities. However, the toxicity of vanadium, high cost of cobalt, low conductivity of manganese-based materials, and high operating voltage (>4.8 V vs Li/Li + ) of nickel-based materials have hampered the commercialization of these materials.…”
