The Industrial Revolution and early developments The principle of the division of labour and the resulting specialization of skills can be found in many human activities, and there are records of its application to manufacturing in ancient Greece. The first unmistakable examples of manufacturing operations carefully designed to reduce production costs by specialized labour and the use of machines appeared in the 18th century in England. They were signaled by five important inventions in the textile industry:
Carbon Cusually graphite C6 Electrolyte: It illustrates the reactions at the Cathode, Anode and Overall Allgemein. The cell performance depends on: Ions can only penetrate "from the side".
This yields a charging rate that is generally lower than the discharge rate. When using nanotechnology, the graphite layers, with finer "nanoporous" structure, yields a larger active surface.
The most relevant are Zone 2, between the cathode and electrolyte and Zone 3 between the electrolyte and anode. The latter, in particular, is extremely important for the function of the cell. The graphite anode would be destroyed by reactions with the electrolyte without it.
To stop this process, a protective coating has to be applied on the carbon. This layer is called the solid electrolyte interphase SEI layer. Lithium ions must penetrate it during charging and discharging.
The SEI-Layer provides protection and stabilization of the anode. Without an SEI layer there is no cycle stability. Unfortunately the SEI layer results in an increase in internal resistance. The thicker the layer, the higher the resistance.
The thicker the layer, the less remaining capacity there is because of decreased lithium transportability. The thicker the layer, the more sensitive it is to plating deposits.
The SEI layer is basically constructed in the preparation of the cell. Any cell which is 'new' has already experienced at least one preparation cycle.
The SEI layer grows during the life of the cell. The more degradation products that are caused in the cell, the thicker it is. High pressure and temperature accelerate this degradation.
Dichtegradient means density gradient. This happens when charging, not during discharge. When the cell reaches maximum capacity, overload can occur to the already fully replenished anode greater than 4.
The transport capacity can be reached by using too high of a charging current, charging at too low of a temperature and the state of the cell's aging, caused by deposits of the oxidation products of the electrolyte and SEI Layer thickness. This excess material on the Anode is referred to as "Overhang".
This condition is called a "Micro Short". The resulting defect leads to further plating. If the runaway temperature is reached locally, and the affected area is sufficiently large, it spreads very quickly through the entire cell.Early History of Water-based Transportation The historical development of water-based transportation is connected to the importance of domestic and international trade.
The outstanding contribution of the automotive industry to technological advance was the introduction of full-scale mass production, a process combining precision, standardization, interchangeability, synchronization, and continuity.
