What are the applications of Lithium battery storage batteries?

What is lithium battery energy storage?

Lithium battery, also known as lithium-ion battery, is a secondary battery that relies on the movement of lithium ions (Li+) between the positive and negative electrodes to achieve the purpose of charging and discharging. Compared with other major secondary batteries, lithium batteries have obvious advantages such as high energy density, high discharge power, long cycle life, no memory effect and green environmental protection. The specific situation is as follows:

When electrical energy is needed, the lithium battery energy storage system converts the stored electrical energy into direct current output, which is processed by inverters and other equipment and then supplied to the external load. At this time, lithium ions migrate from the negative electrode to the positive electrode, while releasing chemical energy to generate electrical output.

According to terminal applications, the downstream of lithium batteries can be mainly divided into three major areas: power, consumption and energy storage.

• The main application areas of power lithium batteries are electric vehicles, electric light vehicles, power tools, etc., which are the main application scenarios of lithium batteries at present (automotive power batteries are also called "large power batteries", and power batteries for electric light vehicles/power tools are also called "small power batteries");
• Consumer lithium batteries are mainly used in mobile phones, laptops, and recently emerging consumer electronic products such as Bluetooth headsets and wearable devices, which are important application areas of lithium batteries;
• Energy storage lithium batteries mainly provide support for the energy storage needs of communication base stations, user-side peak shaving and valley filling, off-grid power stations, microgrids, rail transit, etc., which are emerging fields that have developed rapidly in recent years and are strongly supported by national policies.

Benefiting from the rapid development of the three major sub-sectors of power, consumption and energy storage, the lithium battery industry will continue to maintain a rapid growth trend. The development overview of each sub-sector and the specific situation of future trends are as follows:

Power lithium batteries are currently the most important application market for lithium batteries, mainly used in three fields: new energy vehicles, electric light vehicles, and power tools. On the policy side, in the macro context of responding to climate change and promoting green development, new energy vehicles have become a recognized mainstream development direction with their obvious advantages in energy efficiency, environmental protection and intelligence.

2. Consumer lithium batteries will grow steadily

Consumer electronic products mainly include smartphones, laptops, tablets, and smart hardware. Due to the rapid development of integrated circuits and Internet of Things technologies, the functions of consumer electronic products are becoming increasingly powerful, and the application scenarios are constantly expanding, gradually becoming an indispensable necessity for people's daily life, office, and entertainment.

3. The energy storage lithium battery market has huge development potential

Governments around the world are actively promoting energy transformation to cope with the impact of climate change strategies and the increasing proportion of renewable energy in the power system. Its intermittent and volatile problems urgently need to be solved by energy storage. In addition, the demand for stable power supply in new infrastructure fields such as 5G base stations and data centers has jointly promoted the continuous expansion of the energy storage lithium battery market.
