Future development trend of energy storage
The development of new energy technologies, such as solar, wind and tidal energy and other renewable energy has made considerable progress, and as the cost of related technologies continue to decline, the efficiency continues to improve also makes renewable energy in the proportion of energy production continues to increase, the demand for energy storage technology will continue to increase.
The development of regional energy systems and microgrids will also become a huge impetus for the growth of the energy storage market, will be more integrated and flexible management of renewable energy and traditional energy, to better meet the energy needs of different regions.
According to industry data, the energy storage market is expected to grow rapidly in the next few years, mainly due to government policy support, energy system modernisation and energy storage technology updates, which will also provide more business opportunities and development space for energy storage companies. Therefore, the prospect of energy storage is very worth looking forward to, which is conducive to improving the reliability and stability of the energy system can also achieve the purpose of sustainable energy.
The key role of 18650/21700/4680 batteries
Battery aging, charging and discharging, external environment and its own design defects may lead to the battery pack heat dissipation is not timely, resulting in overheating of the battery pack, which makes the battery performance degradation, and even the risk of thermal runaway.
The 18650/21700/4680 batteries are the models of Tesla’s three generations of batteries respectively. The 4680 battery, for example, refers to a cylindrical battery with a diameter of 46 mm and a height of 80 mm, and was formally announced by Tesla at the 2020 Battery Day in relation to the battery.
The 18650 battery is the earliest and most stable lithium-ion battery, the earliest and most mature lithium-ion battery, most widely used in conventional electronics and pure electric products.
The 21700 battery is the second generation battery, developed by Tesla and Panasonic. Compared with the first generation battery, it has a higher energy density and faster charging speed, but it is still a little bit inferior to the square battery, and it only improves some of the shortcomings of the 18650 battery. Applied to small power, cleaning tools, portable energy storage, electric motorbikes and other fields.
The third generation of batteries, also known as 4680 batteries, adopts a new type of electrodeless ear technology, which greatly improves the range and productivity, and also improves the effectiveness of thermal management while taking into account the energy density. Combined with CTC technology, it is expected to gradually penetrate from Tesla to high-end EV manufacturers such as BMW and Daimler, and will be widely used in the field of energy storage while adapting to light-weight vehicles.
Innovation and application of liquid cooling technology
Lithium batteries in the charging and discharging process will accumulate a large amount of heat, not only damage to the equipment, affecting the battery performance at the same time there is also a security risk, so the need for the corresponding thermal management technology. With the improvement of related technology and the decrease of material cost, liquid cooling is the heat dissipation solution adopted by mainstream manufacturers, especially in the field of large-scale application of Li-ion batteries such as electric vehicles, portable electronic devices and energy storage systems.
The principle is that the coolant absorbs the heat from the electronic equipment through the pipeline or heat sink, and brings the heat into the chiller to complete the heat step in one place, ensuring that the battery operates in a stable temperature range, improving the energy efficiency of the battery system while reducing energy loss.
The advantage is that it can cool the whole battery module more evenly, avoiding local overheating, thus reducing safety hazards; at the same time, the compact design occupies less space, which is more friendly to the application of electric vehicles and energy storage equipment with restrictions.
The Key Role of Bends in Heat Dissipation
Explain the role and importance of bends in liquid-cooled heat dissipation systems / Mention the customised design and manufacture of bends to meet the needs of different applications.
The elbow is a heat sink component designed with a unique hollow structure of tubing and developed with highly refined manufacturing quality. Its large internal surface area allows for more efficient heat transfer and is therefore widely used in battery packs using cylindrical cells.
Aluminium is often used, as it is in direct contact with the coolant and needs to be corrosion resistant, thermally conductive and tough, so 3003 aluminium alloy is a good choice.
The design is customised and involves factors such as length, shape, bend radius, material, connection and fluid dynamics of the bends.
Trumonytechs is equipped with a mature heat exchanger design team, material R&D labs, and batch production lines for polymer materials, and its existing tube bends serve many application scenarios, such as new energy vehicles, energy storage, mobile electronic devices, medical, optical, and other industries.
Trumonytechs has been working in the thermal management industry for a long time, and has professional R&D, design and production teams to provide customers with one-stop solutions for tube bending, simulation and thermal interface materials.
