In 2024, the global energy storage market continued to maintain a high rate of development, with the installed capacity of newly commissioned power storage projects reaching 82.7 GW, a year-on-year increase of 59.0%. Among them, the new energy storage installed capacity accounted for nearly 90%, reaching 74.1 GW. China's performance in the field of new energy storage is particularly outstanding, the new installed capacity reached 43.7 GW, accounting for about 60% of the global new installed capacity. By the end of 2024, China's cumulative power storage installed capacity reached 137.9 GW, of which the installed capacity of new energy storage reached 78.3 GW, for the first time exceeding the installed capacity of traditional pumped storage.

Energy storage, as its name suggests, is the temporary storage of various forms of energy, such as electricity and heat, and then release them when needed. It is like a magical ‘energy box’, which can ‘eat’ into the energy when energy is abundant, and then ‘spit’ out when energy is tight or needed. Doesn't this sound like a scene from a science fiction film? But in fact, this is already a real part of our lives!

Energy storage technology is like a magical treasure trove of energy, and its emergence is no accident. With our growing demand for energy, especially those clean renewable energy, such as wind, solar energy, although they are very environmentally friendly, but has a small temperament - rely on the sky to eat. When the wind stops, wind turbines can't turn; when the sun goes down, solar panels go on strike. At this time, the energy storage technology to come forward, the excess energy stored, wait until the time of need and then released, so that the energy supply is as stable as Mount Tai. Second, energy storage ‘warrior’ of the great martial arts

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.
