The growth procedure and also the future trend of a power storage battery

Huge capacity is the trend, and making power to be strengthened

With the fast development of the energy storage sector, the scale of power storage space power plants is hundreds of megawatt degrees or even Gava levels. Proprietors ask for personalized as well as specialist power storage batteries to climb.

According to Liu Yong, the assistant general of the Energy Storage Space Application Branch of the Chinese Chemical and Physical Power Sector Organization, energy storage batteries will most definitely open their independent growth tracks in the future. This is not only the need for lowering expenses and performance but also a demand for secure development.

Huge ability is the fad

In a set of electrochemical energy storage space systems, battery expenses make up around 60%. In recent years, the range of the energy storage space industry has expanded high, and also the pressure decrease pressure has been superimposed. The industry has put forward an urgent need for a high economic climate of power storage batteries.

In 2020, Ningde Times took the lead in introducing a 280AH cell with a long-cycle life and also progressively replaced the initial 50AH-100AH battery cell, coming to be the requirement for the bidding of energy storage projects or product procurement. The mainstream battery manufacturers of the sector have followed up, and the 280AH battery cells are largely launched.

In August, Xiamen Haichen Energy released the first 300AH electric energy storage battery and large cylindrical energy storage battery for energy storage. In October, Yimei Energy released a new generation of energy storage battery LF560K, which further pushed the battery capacity to 560Ah.

In the view of Zhang Wancai, the product manager of Haichen Energy Storage, developing energy storage batteries to a larger capacity is one of the technological iteration trends. The cost of large-capacity batteries through diluted battery structures, reducing the number of components of system groups, simplifying production line processes, reducing the number of equipment, reducing manual investment, etc., reducing the cost of the energy storage system.

Hereof, Liu Yong agreed that the development path of power storage batteries is to increase and reduce cost performance with technological technology upgrades. The tiny-ability battery is utilized. It can successfully minimize the number of prefabricated areas, and the price of electrical power additionally has a certain decrease, which can considerably enhance customers' total financial investment income.

Yiyi Lithium Energy Power Iron Battery Chief Innovation Guanyuan Tintin got a set of information: Compared with the previous LF280K energy storage battery, the use of LF560K batteries can lower the variety of batteries by 50% and decrease the variety of battery pack elements by 47%. Enhance manufacturing performance by 30%.

Safety is a prerequisite

Individuals in the sector believe that the current period of innovation concentration of power storage batteries has changed into a period of innovation focus. In addition to large ability, high voltage, and liquid air conditioning systems are prominent in the market.

Today, more suppliers in China have started to develop and produce energy storage battery assembly lines, including Yiwei Lithium Energy, Penghui Energy, Haichen Power Storage Space, Ruipu Lanjun, Chu Nengxin Power, and also Vision Power. Battery companies have released special energy storage batteries to take growth possibilities.

It is worth noting that the development of energy storage batteries must be based on safety, and the battery capacity is not blindly sought. At the same time, the battery may cause the problem of battery drum swelling, which will cause overcoming and thermal out of control.

" Safety is the bottom line of the advancement of the power storage space industry." Sector experts highlighted to reporters that the power storage market is still at the beginning of development, and the technical standards and approval requirements are not excellent. Customers might find it difficult to identify various power storage innovations and their items. In this situation, some ventures that do not have stamina have blindly introduced a large -ability task, boosting surprise safety risks. "Big ability is not considerably enlarged. To accomplish a balance of great ability, high safety and security, and long cycle life."

Zhang Wancai likewise stated that battery energy storage is not a power source but a transportation terminal with capacity restrictions.

Which scenes suit small batteries, and which scenarios need large batteries? Large storage systems are usually more suitable for matching large-capacity batteries, which can greatly increase the energy density of energy storage systems.

Manufacturing capacity still needs to be strengthened.

This year, the demand for energy storage markets is extremely strong, and the supply of 280AH batteries has appeared tight. For manufacturers, it requires a certain expansion cycle, whether it is a new special energy storage battery production line or upgrading the original power battery production line.

It is understood that the production of energy storage batteries mainly has two techniques: stacks and wound surrounds, with a high degree of automation and high production efficiency. However, the requirements for the consistency of the 280AH cells to be produced in the manufacturing process are much higher than the 50AH-100AH battery.

Liu Yong explained that the small battery cells generally use a rolling process with high production efficiency. Production line. The key is to ensure the safety, efficiency, and stability of electrochemical materials in the production process.

"The production efficiency of large battery cells is lower than that of small cells, which is a physical law." Zhang Wancai further pointed out that large-capacity batteries have put forward new requirements for production equipment. Taking the existing 280AH smart production line of Haichen Energy as an example, all assembly, all assemblies On the process and equipment of the section and test section, the R & D and manufacturing team has carried out corresponding design and development and has done a lot of work. In the future, the creation of higher production capacity lines will remain continuous in technology research.

In addition, the energy storage market has not reached a stage of large-scale development. In the first half of this year, the scale of newly added planning and under construction was close to 130 Gavaco, and the actual investment volume was less than 1.5 Gavaco. The energy storage business model has not yet matured, the upstream raw materials prices are superimposed, and the expansion of battery companies is more cautious.

In May of this year, Chu Neng New Energy released the "Chu Neng -1" product, with a battery capacity of 280AH and a single battery cycle life of more than 10,000 times. In August, Xiamen Haichen Energy released the first 300AH electric energy storage battery and large cylindrical energy storage battery for energy storage. In October, Yimei Energy released a new generation of energy storage battery LF560K, which further pushed the battery capacity to 560Ah. The cost of large-capacity batteries through diluted battery structures, reducing the number of components of system groups, simplifying production line processes, reducing the number of equipment, reducing manual investment, etc., reducing the cost of an energy storage system.

It is worth noting that the development of energy storage batteries must be based on safety, and the battery capacity is not blindly sought.
