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 ...
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 ...
A phase-change is the melting, solidifying, vaporizing or liquifying. Such a material is called a phase change material (PCM). Materials used in LHTESs often have a high latent heat so that at their specific temperature, the phase change absorbs a large amount of energy, much more than sensible heat. [39]
An encapsulated thermal battery is physically similar to a phase change thermal battery in that it is a confined amount of physical material which is thermally heated or cooled to store or extract energy. However, in a non-phase change encapsulated thermal battery, the temperature of the substance is changed without inducing a phase change.
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.

Peltier cooling plates / ˈ p ɛ l t i. eɪ / take advantage of the Peltier effect to create a heat flux between the junction of two different conductors of electricity by applying an electric current. [9] This effect is commonly used for cooling electronic components and small instruments.
