I have read many research article they have given phase change material for thermal energy storage. I want to know other material such as composite, alloy and PCM material to store thermal energy for more heat for long time.
Energy storage can be achieved by localizing charges in a dielectric (ref AIP Advances 8, 095228 (2018), https://doi.org/10.1063/1.5047673).
Can we imagine a heat generator using this principle?

Molten salts have huge advantages of simplicity for thermal storage. Currently it is always nitrate salts which have a top temperature of 600C but at higher temperatures simple chloride salt mixtures could be used. A quaternary eutectic melting at 385C (https://ac.els-cdn.com/S1876610215011753/1-s2.0-S1876610215011753-main.pdf?_tid=521ac49b-e535-42f0-9d78-836b34db3136&acdnat=1552311946_efacfb5d315b2b0001d01d3fe6a5bc7b) could be used in a thermal store cycling between 500 and 1000C which would be very cheap and store heat at an industrially very useful temperature.
Dear Chhottelal Prajapati,
The following article may helps you,

Hello,
Have you seen the videos on "prince rupert drop"? Any insulator can behave like an energetic material. I'm working on exploring this path.

@Claude Can you describe the principal of how we can use the Prince Rupert drop as an energy storage material. As I know it is a molded glass material which suddenly cools in water and it forms a toughened glass. When it has an impact that breaks from leading points.
Hello,
I answered your very prospective initial question by proposing a very little known method of storing thermal energy. I then referred you to an experiment which dates from the 17th century and whose microscopic explanation has not been provided. To explain how to go from Prince Rupert's experience to energy storage requires to return to the mechanisms of breaking chemical bonds, of localizing energy ans strains around the defects , to the mechanisms of dielectric losses, of instabilities under electrical and mechanical stress, to mechanical shock and initiation of explosions. In doing so, we must also return to calculation techniques developed in continuous medium mechanics. It is then necessary to carry out the heat flux measurements during the storage stage and during the energy relaxation stage. Finally, materials must be chosen using techniques that provide information on the energy they can accumulate before exploding. There are then three sources of energy to consider: the energy of the material used, the energy it can store and the energy it returns. We are then able to carry out an energy balance and demonstrate the functioning of a system which absorbs energy from the external system for a long time and restores it for a short time. A mass glass with internal stresses is a system of this type where restitution can be triggered by an small disturbance.
I hope this answer inspires you to continue. If you would like further help from me I would ask you to contact me on my personal email .

Hi ,
I think the following article also very helpful to you,
https://www.sciencedirect.com/science/article/abs/pii/S1364032107001402
Rudrarapu Aravind Thank you for your response but here I am come to discuss with some technology and idea behind in new energy storage material. as describe by Claude Le Gressus Sir, I have also many journal papers available about this.
Thank you, Claude Le Gressus Sir for your valuable reply, I am less aware that I think I will have to read and learn more about it. If you have any paper in this regard, please share it with me.
Regards
