When it comes to energy storage, electrochemical energy storage has to be mentioned. Among them, lithium-ion batteries are currently the ‘star of the show’. It is like a high energy density, light weight, small size of the ‘small hand’, widely used in consumer electronics, new energy vehicles and energy storage field. However, lithium-ion batteries also have their own ‘temperament’, such as safety challenges, thermal runaway is the focus of research.

Imagine a sunny afternoon, your home's rooftop solar panels are generating electricity, and the excess power is stored in a home energy storage system. When the sun goes down, this stored energy is released to power your home. It sounds like a scene from a science fiction film, but it's a reality today. As technology advances, energy storage devices are becoming smaller and smarter. For example, some portable energy storage devices can already easily fit into a backpack to provide power support for outdoor activities. This technology not only facilitates individual users, but also provides a reliable energy solution for emergency rescue and remote areas. V. Future outlook: how can energy storage change our lives?

Speaking of energy storage, we have to mention lithium-ion batteries. It is the energy storage sector's ‘popular little boy’, with high energy density, long cycle life and fast charging and discharging and other advantages, has become one of the most popular energy storage technology. From our smart phones to electric vehicles, to large-scale energy storage power stations, we can see the figure of lithium-ion batteries. It is like an energetic young guy who can always bring us surprises. However, lithium-ion batteries also have some minor drawbacks, such as relatively high cost and some safety issues that may arise in extreme environments. But don't worry, scientists are working hard to overcome these challenges and make lithium-ion batteries even better.

Imagine how convenient it would be if electricity could be charged and used at any time like a mobile phone. Energy storage technology is such a ‘supercharger’. It can be stored when there is an excess of power and released when there is a shortage of power, solving the limitations of instant power.

In the arena of energy storage, battery energy storage is definitely the ‘big star’. Speaking of batteries, we may immediately think of mobile phone batteries, electric car batteries. But energy storage batteries can be much more powerful than them, they are like the battery sector ‘giant’. Lithium-ion batteries, for example, it is like a super-capable ‘small hands’, high energy density, like a small ‘energy box’, can hold a lot of energy. And it charges and discharges quickly, like a super ‘courier’, can send the energy out quickly, but also can be quickly retrieved. Moreover, the lithium-ion battery life is also very long, like a super ‘endurance king’, can withstand many times the test of charging and discharging. Now, lithium-ion battery storage system has been widely used in many places. For example, in some large solar power station and wind power station, installed next to the lithium-ion battery storage system, like a super power station with a ‘backup power’. When the solar and wind power generation is insufficient, the energy storage system can be timely ‘fill in’ to ensure a stable supply of electricity. Moreover, lithium-ion battery storage system can also be used in some remote areas, such as islands, mountainous areas, etc., these places may not be very stable power grid, with the energy storage system, you can let the residents there can also use stable electricity, and live a comfortable life in the city.

Dr Yan Renwu and his team from Fujian University of Technology introduced the faculty strength and rich teaching experience of the School of Electrical, Electronic and Physics of the university. The establishment of the joint training base aims to provide students with education that is closer to the actual industrial needs and to cultivate high-level professionals with excellent practical skills.
