It is not an exaggerated fact that the whole world relies on the energy storage systems such as Li-ion batteries (LIBs). Li-ion batteries have been widely used in electric vehicles and electronic devices such as laptops, mobile phones, etc. However, the commercial Li-ion batteries have many issues associated with safety and durability including the thermal runaway and the use of toxic solvents during the construction of batteries. In order to highlight the recent developments towards addressing these issues, we have summarized the major impact in replacing the toxic solvents, which are conventionally used to dissolve the binder in the commercial Li-ion batteries, with the aqueous-based binder called green binders. Further, an emphasis has been given on the importance of shifting from flammable liquid electrolytes to non-flammable solid-electrolytes, which essentially suppress the issues such as leakage problems, mechanical failure and fire explosives in LIBs. Even though considerable works have been performed on the development of green-based solid polymer electrolytes, it still needs more effort to overcome the obstacles towards improving the properties of the solid-polymer matrix, which is their low ionic conductivity at low temperatures. Further research in this direction has been highlighted in this review, which involves improving the interfacial contacts in the solid-polymer electrolytes, where the interfacial interaction and conductive mechanisms are yet to be clearly investigated to have the solid-electrolytes with improved electrochemical property.

This work presents the isolation of Low-Density Lipoprotein (LDL) from blood. The blood molecules with size less than 1µm are filtered in the size based crossflow filter technique. Filtered molecules are passed through the Porous Silicon (PSi). The immobilized Anti-Apolipoprotein B (AAB) on the surface of Porous Silicon is used to adsorb the LDL. Isolation of LDL based on Porous Silicon eliminates the calculation of the other lipoproteins and Triglycerides. Filter with AAB coated PSi is designed and simulated in COMSOL Multiphysics software.
