A phase-change material (PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat or cooling. Generally the transition will be from one of the first two fundamental states of matter - solid and liquid - to the other. The phase transition may also be between non-classical states of matter, such as ...
A cold-energy battery utilizes the properties of an advanced phase-change material (PCM) to maintain temperature as battery thermal management. As with a standard electrical battery, a cold energy battery stores energy and releases depending on the energy demand on it. It can then be recharged by placing in a temperature environment conducive ...
Maintenance of marine heat exchangers is important to ensure the small pathways in both types of coolers do not become fouled. Depending on the system different types fouling may occur. In oil based systems, an insufficient amount of cooling medium or inefficient flow of oil through the heater can cause the heater to become fouled.
Recent research on PCM has been directed towards attempting to find viable material alternatives to the phase-change material Ge 2 Sb 2 Te 5 (GST), with mixed success. Other research has focused on the development of a Ge Te – Sb 2 Te 3 superlattice to achieve non-thermal phase changes by changing the co-ordination state of the germanium ...
Computational Fluid Dynamics (CFD) modeling and simulation for phase change materials (PCMs) is a technique used to analyze the performance and behavior of PCMs. The CFD models have been successful in studying and analyzing the air quality, natural ventilation and stratified ventilation, air flow initiated by buoyancy forces and temperature space for the systems integrated with PCMs.

The electric vehicle battery accounts for 30–40% of the value of the vehicle. [1] Around one-third of the battery's weight is the housing and cooling system. The cathode makes up another 20% and the anode another 10%. [2] Three types of batteries dominate the electric vehicle market.
