Engineering evolution vs industrial framework optimization

Yin Ruiyu

Strategic Study of CAE 2012, Volume 14, Issue 3,   Pages 8-14

Abstract:

Engineering is a human activity to construct and create artificial entity in a well-organized, planned and purposeful way by means of various resources and basic economic elements. Engineering is the direct productivity .Engineering is a dynamic system which is combined and integrated with related technology groups and a crop of basic economic elements under certain natural and social conditions. Technology integration system embodies the specified frame and dynamic operating ways formed by the dynamic and ordered integrating process of related but varied heterogeneous technology groups. This system must be allocated properly to and has a harmonious interaction with basic economic elements under certain natural and social conditions, such as resource, labor, land, capital, market and environment, and so on. They will form an engineering system and produce the specific and desired function and valued by being designed, constructed and operated. Engineering has the close relation but some difference with science, technology and industry. From the point of economy and its structure, engineering is the micro-unit, industry is the meso-unit, and industrial framework which is made of different industries is the macrounit. Engineering is evolving constantly. The engineering evolution propels forward the industrial development and the adjustments of industrial framework, even if the appearance of industrial revolution.

Li4SiO4-coated LiNi0.5Mn1.5O4 as the high performance

Shifeng YANG, Wenfeng REN, Jian CHEN

Frontiers in Energy 2017, Volume 11, Issue 3,   Pages 374-382 doi: 10.1007/s11708-017-0494-2

Abstract: The preparation of Li SiO -coated LiNi Mn O materials by sintering the SiO -coated nickel-manganese oxides with lithium salts using abundant and low-cost sodium silicate as the silicon source was reported. The samples were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. It was found that a uniform and complete SiO coating layer could be obtained at a suitable pH value of 10, which transformed to a good Li SiO coating layer afterwards. When used as the cathode materials for lithium-ion batteries, the Li SiO -coated LiNi Mn O samples deliver a better electrochemical performance in terms of the discharge capacity, rate capability, and cycling stability than that of the pristine material. It can still deliver 111.1 mAh/g at 20 C after 300 cycles, with a retention ratio of 93.1% of the stable capacity, which is far beyond that of the pristine material (101.3 mAh/g, 85.6%).
