Finally, the most recent developments and prospects for new lithium-ion battery materials and their impact on capacity and degradation are discussed. Moreover, increased temperature seems to be the most detrimental factor for almost all chemistries for both cycling and storage although the critical temperature differs. The results indicate that the NMC/hard carbon battery performed best when evaluating the cycling, the LFP/graphite batteries are more stable in terms of calendar ageing. Moreover, a literature review of studies investigating the capacity degradation is included and compared in terms of the influence of operating conditions on the lifetime of lithium-ion batteries for different chemistries. It summarises the most recent developments in applications of lithium-ion batteries, the accompanying new requirements and operating conditions. This chapter gives a brief introduction into the working principle of lithium-ion batteries, the most common commercially available cathode materials lithium cobalt oxide (LCO), nickel cobalt manganese oxide (NMC), lithium manganese oxide (LMO) and lithium iron phosphate (LFP) and the anode materials hard carbon and graphite. The most urgent requirements are cost reduction, accompanied by an increase in battery life. However, for being fully compatible with alternative technologies, there are still obstacles to overcome. Lithium-ion batteries have become the leading energy storage technology in many sectors due to their superior properties. It is also very hard to melt.The transition from fossil fuels to renewable energy sources requires reliable energy storage technologies. It is very easily oxidized and like iron it reacts to water and rusts. When pure, manganese can be very reactive and as a powder it can burn in oxygen. Manganese is a hard, but very brittle metal with a pink-gray color. The latter being the market segment in which Umicore sources manganese for its rechargeable battery materials activities. Other forms of manganese are mainly manganese metal and chemicals. The main market for manganese is in the form of a manganese ore, which is shipped to China for further processing into stainless steel and other applications. The highest concentration of reserves and mining activity are located in South Africa. Manganese mines can be found all over the world. Of course, throughout history, its applications became more diverse from replacing nickel in US coins during World War II to using manganese dioxide as a catalyst.Īlthough the name may be associated with magnetism, this metal is not magnetic on its own. The use of these pigments can be traced back to the Stone Age, when the pigments were used in cave paintings. Manganese pigments are also used in the glass industry to give glass a violet color. Umicore is a global leader in NMC cathode materials. The manganese in the cathode material has an important impact on the safety of the battery cells and safety is a main priority when it comes to batteries that power electric cars and electric devices. Their composition helps determine how long you can talk on the phone, how far you can drive an electric car, how fast a battery can recharge and how much energy you can store from your solar panels. It acts as a stabilizer in the structure of NMC (nickel manganese cobalt) cathode materials and cathode materials are the key performing drivers of Li-ion batteries. One might not realize this, but manganese plays an important role in battery powered products. For lithium-ion batteries, the segment in which Umicore is active, it accounts for less than 1% of global demand. Other applications are non-ferrous alloys and alkaline batteries, both covering around 2% of global manganese demand. It is a key component for stainless steel formulations and often used with aluminum alloys. Manganese is very important when it comes to iron and stainless steel production, accounting for over 90% of the manganese mined today. On average, the human body contains about twelve grams of manganese, mostly found in our bones. We can find it in our stainless steel watches and in batteries powering our devices, but also in the human body. Although you may think that manganese is a pretty rare metal, it is very common in our daily life. Did you know that manganese received its name from the Greek region of Magnesia? It is not found as a free element in nature, but it is often extracted in combination with minerals like iron.
