EV Technology

  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...

  About:  This cell chemistry aims to overcome the shortcomings of conventional cells such as non-uniform discharge rate, chemical stability, high cycling rates and number of charge-discharge cycles Was developed at MIT, USA Technology Description  The name 'Nanophosphate' comes from the nano phosphate material which replaces the conventional phosphates  Results in better conductivity and more uniform discharge rate The cathode is coated with nanoparticles The nanoparticles range in size from one-tenth of a micron in diameter to several microns Overcomes the slow reaction rate of conventional phosphates due to this structure, the chemical reactions increase the cathode surface area with the electrolyte, which allows for faster lithium insertion resulting in greater power References  https://www.disruptordaily.com/nanotechnology-nanophosphate-batteries-manufactured-today/#:~:text=The%20nanotechnology%20is%20actually%20a,discharge%20rate%20than%20convent...

Li-titanate replaces the graphite in the anode of a typical lithium-ion battery and the material forms into a spinel structure. The cathode can be lithium manganese oxide or NMC. Li-titanate has...
