Study on Electrochemical Impedance Spectrum Analysis of LiFePO4 in Aqueous Solutionsby Using Powder Microelectrode NaHa1, a,Jiemin Liu1,b* 1School of Chemistry and BiologicalEngineering, University of Science and Technology Beijing ahairi0513@163.com,bliujm@ustb.edu.cn Keywords:Microelectrode,Aqueous electrolyte,LiFePO4,Equivalent circuit Abstract.LiFePO4is becoming promising lithium ion cathode material.
LiFePO4 presents excellent cycling behaviors, attributed to the enhancement of the electronic conductivity by the porous carbon matrix and carbon coating, and also to the cycle performance of LiFePO4 itself due to the high stability of the olivine structure [5].
As we can obtain from SEM, as result of their peculiar structures, electrons are delivered easily[11].

Introduction Synthesis and investigation of eco-friendly waterborne polyurethanes (WPU) is one of the promising directions for the development of polymer chemistry.
Furthermore, OICUare of fire, heat and chemical resistance, as well as resistance to UV radiation and hydrolysis [1].Thus, the introduction of these structures into the polymer chain during the synthesis of the WPUcan provide the target product with the properties stated above.
The polymer obtained by synthesis of OICU-based polyurethanes with various oligodiols has a three-dimensional structure due to the high content of NCO groups of OICU IPDI, which can ultimately result in crosslinked products obtained.

Concrete structure durability involves mechanics, material, physics, chemistry, electrochemistry, physical chemistry environment and so on.
The traditional concrete structure design mainly concerns the influence that load function to security of the structure supporting capacity and the influence that the restraint distorts (crack, deflection and so on) to the structure operational performance, but takes very little concerns to the influence that the structure working conditions to the structure long-term performance.
If in the structure design, the function effect environmental factor to the concrete structure is not fully considered, the concrete structure design datum time cannot obtain the guarantee in the actual service process.
Ÿ In line with whole structure life design idea, based on time-varying of structure resisting force and environment function, we propose the durability design system of whole structure life with the limit breakage state as control goal by stages to perfect the structure durability design system.
