The meaning of the word democracy in India is becoming contradictory. After getting the election and the post, the responsible are moving ahead and the people are lagging behind. This has been going on for years. After gaining power, the sentiments of the people are of no importance to the leaders. Due to this the society is also lagging behind. Earlier leaders lived for the values ​​in the society and now its meaning is changing. Due to this, it has become very important for the youth to pay attention to it. If we brainstorm on every small and big incident, it comes to the fore that this happens due to the disconnection of the responsibilities from the society. It is also surprising that things like democracy are given very little importance in the education system. Due to this, lack of knowledge about people is also making the society weak. For this, it is most important that those youths who have new thinking. They have the will to take the society forward and they should come forwa...

The app will facilitate webinar sessions which act as a bridge between students and experienced medical professionals. The other faci...

  About: In the automotive battery industry, one of the most successful Li-ion chemistries is the cathode combination of nickel manganese cobalt oxide (NMC). LiNi1-x-yMnxCoyO2 (NMC) has similar or higher specific capacity than LCO and similar operating voltage while having lower cost since the Co content is reduced. LiNi1/3Mn1/3Co1/3O2 (NMC-111) is the most common form of NMC and is widely used in the battery market. Another successful combination of NMC is LiNi0.5Mn0.3Co0.2O2 (NMC-532). Other combinations using various amounts of metals are possible.  Technology Description: ​​​​​​​​​​​​​​ For NMC, nickel is known for its high energy density but poor stability. Manganese has the benefit of forming a spinel structure to achieve low internal resistance, but gives a low specific energy. Combing the two metal elements can improve each other’s merits. NMC-based battery technology is also well-suited for EV applications...

  About  As the cost and availability of Lithium is an issue, the search for alternate materials is going on  Sodium is an alternate material which is cheaper and more abundant in nature Technology Description  The Na-Ion batteries use (Na) Sodium as the cathode instead of Li They are cheaper and more abundant but lose out on energy density  The cells are more durable in nature Type of anode material (hard carbon) used for these types of cells is different  due to the different size of molecules The general details on this type of cell whose research is being done by Faradion  Parameter Comment  Voltages (V) 4.3 Energy Density (Wh/kg)  >140 Cycling (C-rate)  0.1 to 2 Temperature Range ( 0 C) -20 to 60 References  https://www.freepatentsonline.com/WO2017073066A1.pdf https://www.faradion.co.uk/technology-benefits/strong-performance/

  About: Lithium-ion is named for its active materials; the words are either written in full or shortened by their chemical symbols. A series of letters and numbers strung together can be hard to remember and even harder to pronounce, and battery chemistries are also identified in abbreviated letters.  For example, lithium cobalt oxide, one of the most common Li-ions, has the chemical symbols LiCoO2 and the abbreviation LCO. For reasons of simplicity, the short form Li-cobalt can also be used for this battery. Cobalt is the main active material that gives this battery character. Other Li-ion chemistries are given similar short-form names.   Technology Description: ​​​​​​​​​​​​​​ One of the most successful Li-ion systems is a cathode combination of nickel-manganese-cobalt (NMC). Similar to Li-manganese, these systems can be tailored to serve as Energy Cells or Power Cells. For example, NMC in an 18650 cell for moderate load condition has a capacity of about 2,800mAh a...

It shares similarities with NMC by offering high specific energy, reasonably good specific power and a long life span. Less flattering are safety and cost. NCA is a further development o...
