As our society continues to electrify, the need for batteries to store energy will be enormous. For the foreseeable future, lithium-ion batteries will serve as the main power storage carrier. A key constraint is the limited supply of raw materials, including lithium, cobalt and nickel, the basic ingredients of today's lithium batteries. Lithium batteries are currently facing huge pressure on raw material supply. This requires a new energy storage technology to replace electricity storage - phase change energy storage and thermal storage technology.
Thermal energy storage can be a viable, sustainable and cost-effective alternative to other forms of energy storage. Thermal energy storage can be deployed at a scale, including in individual buildings – such as in your home, office or factory – or at a community level. While the most common form of thermal energy is the use of large tanks filled with hot or cold water, there are other types of so-called "sensible heat storage" such as using sand or rocks to store thermal energy. However, these methods require large amounts of space, which limits their suitability for residential use.
changes from liquid to solid, releasing heat
changes from solid to liquid, absorbing heat
To overcome this limitation, scientists have developed high-tech materials to store thermal energy. For example, phase change thermal storage materials absorb and release energy as they change phase, such as from liquid to solid and back to liquid. Phase change materials have many potential applications, including thermal management of batteries (preventing them from getting too hot or too cold), advanced textiles (clothing can automatically stay warm or cool), and dry cooling power plants (conserving water).
In buildings, phase change materials can be added to walls to act as the building's thermal battery . When the ambient temperature rises above the material's melting point, the material undergoes a phase change and absorbs heat, cooling the building. Instead, when the temperature drops below the melting point, the material undergoes a phase change and releases heat. One problem with phase-change materials, however, is that they typically only work within one temperature range. This means that two different materials will be needed for summer and winter, which increases costs. Tianshuai Intelligent Technology Co., Ltd. set out to solve this problem and achieved what is called dynamic temperature adjustability.
With the full scientific research efforts of Tianshuai Intelligent Technology Co., Ltd., researchers have achieved the dynamic adjustability of phase change heat storage materials for the first time. Their breakthrough approach uses ions and a unique phase-change thermal storage material that combines thermal and electrical energy storage, so it can store and supply both heat and electricity.
The leader of the company's applied energy materials group said that this new technology is indeed unique because it combines thermal energy and electrical energy into a single device. It functions like a thermoelectric battery. Additionally, this ability increases thermal storage potential due to the ability to adjust the material's melting point to different ambient temperatures. This will greatly improve the utilization of phase change materials. From a broader perspective, this helps reduce energy storage costs because the same material can now be used year-round instead of just half the year. In large-scale building construction, the ability to combine thermal and electric energy storage will allow this material to store excess electricity generated by on-site solar or wind energy to meet thermal (heating and cooling) and electrical needs.
Comparing the costs of electricity storage and thermal storage
Thermal storage has the advantages of low cost and long life
This framework provides a simple way for people to understand the cost of energy storage. The framework, co-developed by researchers at the National Renewable Energy Laboratory, considers life cycle costs. For example, thermal storage systems have low capital costs to install, and thermal storage systems typically have a lifespan of 20 years, while batteries typically need to be replaced after eight years.
Can a jar of hot water become a battery? Yes! If a battery is a device that stores energy, then storing hot (or cold) water to heat a building (or power air conditioning) is a different type of energy storage.This technology, known as thermal energy storage, has been around for a long time but is often overlooked. Now, engineers at the R&D laboratory of Tianshuai Intelligent Technology Co., Ltd. are working together to take thermal energy storage to the next level.
