LaNiO3 as a Novel Anode for Lithium-Ion Batteries

Abstract

Lithium-ion batteries (LIBs) have been developed for over 30 years; however, existing electrode materials cannot satisfy the increasing requirements of high-energy density, stable cycling, and low cost. Here, we present a perovskite-type LaNiO 3 oxide (LNO) as a new negative electrode material. LNO was successfully synthesized by a sol-gel method. The microstructure and electrochemical performance of LNO calcined at various temperatures have been systematically investigated. The LNO electrode shows a high rate capability and long cycling stability. In a Crate test, a specific capacity of 77 mAh/g was exhibited at 6 C. LNO can also deliver a specific capacity of 92 mAh/g after 200 cycles at 1 C. This paper presents a type of binary metal oxide as a new anode material for high-performance LIBs.

Niobium Tungsten Oxides for Electrochromic Devices with Long-Term Stability

“…The Nb 18 W 16 O 93 film was prepared by a conventional sol–gel method (Figure S1 in the Supporting Information), which is a simple process, with mild reaction conditions and low requirements for equipment. − To determine the crystal structure and phase information, the high-resolution X-ray diffractometer (XRD) patterns of the Nb 18 W 16 O 93 film and bare fluorine-doped tin oxide (FTO) substrate are used, as shown in Figure a. In the XRD patterns of the Nb 18 W 16 O 93 film, two main peaks of the calcined Nb 18 W 16 O 93 thin films are observed, which are about 22.49° and 45.90°, respectively, corresponding to the diffraction of the orthorhombic phase (JCPDS 75-0561).…”

High-performance Ta-doped Li7La3Zr2O12 garnet oxides with AlN additive

“…The total resistance of grain and grain boundary could be obtained by fitting the semicircle of the EIS data, and then the total conductivity was determined by using Eqs. ( 5) and (6). Because the electronic conductivity is on the order of 10 -9 -10 -8 S•cm -1 , 4-5 orders of magnitude lower than that of ionic conductivity, the total conductivity could be considered as the ionic conductivity approximatively (Eq.…”

“…Lithium-ion batteries (LIBs) are almost dominating every aspect of our daily e-life, such as 3C electronic products and electric vehicles, and promising in grid-level energy storage systems [1][2][3]. However, the current LIBs have almost reached the peak in the matter of energy density, power density, cycle life, and safety [4][5][6][7]. As the most attractive anode, the lithium metal has an ultrahigh theoretical specific capacity of 3860 mAh•g -1 , a low gravimetric density (0.534 g•cm -3 ), and the lowest redox potential (−3.040 V vs. standard hydrogen electrode (SHE)) [8][9][10].…”

Fast‐Charging Solid‐State Lithium Metal Batteries: A Review
