Uniform lithium deposition induced by copper phthalocyanine additive for durable lithium anode in lithium-sulfur batteries

作者： yixuan zhang College of Law and Humanities and Society Wuhan University of Technology

The promulgation of the Supervision Law of the People's Republic of China marks a new step in the reform of China's supervision system, but it also brings many new problems. This paper focuses on one of the issues: whether deputies to the NPC can be the object of supervision by the Supervisory Committee. There are two opinions on this issue in academia. Opponents hold that the Supervisory Committee is a state organ created by the National People's Congress to be responsible for the supervision of the National People's Congress. If it is allowed to supervise the deputies to the National People's Congress, it is obviously a violation of the principle of democratic centralism clearly stipulated in the Constitution of China and does not meet the requirements of the principle of self-discipline of the Parliament. Therefore Supporters argue that the supervision of NPC deputies by the Supervisory Committee is in line with the legislative spirit and provisions of the Supervisory Law. Whether the supervision of NPC deputies by the Supervisory Committee will affect the exercise of the functions of the power organs of our country belongs to the limitation of the supervisory power of the Supervisory Committee and should not be included in the discussion of the supervisory objects of the Supervisory Committee. This paper gives a brief introduction to both views, but tends to support the views of the critics.

Copper phthalocyanine(CuPc)is adopted as an electrolyte additive to stabilize lithium anode for lithiumsulfur(Li-S)*** with a planar molecular structure and lithiophilic N-containing group,is likely to be adsorbed on the surface of Li anode to form a coating layer,which can restrict the direct contact between Li anode and solvents,and guide the uniform deposition of Li^(+)*** Li||Li symmetric cells demonstrate a stable cycle performance,and Li||Cu cells show high Coulombic *** Li-S batteries,the formed stable solid-electrolyte interface(SEI)film containing copper sulfides can protect Li anode from the polysulfide corrosion and side reactions with the electrolyte,leading to the compact and smooth surface morphology of Li ***,the Li-S batteries with CuPc additive deliver much higher capacity,better cycle performance and rate capability as compared to the one without CuPc additive.
