A one-of-a-kind battery made specifically for chemical power sources’ low-temperature flaws is called a low-temperature battery. Matching positive and negative electrode materials, the low-temperature battery makes use of VGCF and activated carbon with a specific surface area of (2000-500 m2/gas additives). In order to guarantee that the low-temperature battery can discharge at low temperatures, specific electrolytes with specialized additives are injected. In addition, the high temperature has a volume change rate of 0.5% for 24 hours at 70°C, providing the same safety and storage capabilities as conventional lithium batteries learn more.
Lithium-ion batteries that operate at temperatures below -40°C are referred to as “low-temperature batteries.” They are mostly used in military aerospace, vehicle-mounted equipment, scientific research and rescue, power communications, public safety, medical electronics, railways, ships, robots, and other areas. Other applications include these. The discharge performance of low-temperature lithium batteries determines their classification: rate-type low-temperature lithium batteries, energy storage, and lithium batteries that operate at low temperatures Low-temperature lithium batteries can be broken down into industrial low-temperature lithium batteries and low-temperature lithium batteries for military use. Its utilization climate is separated into three series: low-temperature batteries for civilian use, high-temperature batteries for extreme environments, and so on.
Military weapons, aerospace, missile-borne vehicle equipment, polar scientific research, frigid rescue, power communications, public safety, medical electronics, railways, ships, robots, and other fields are the primary application areas for low-temperature batteries.
Benefits and uses of low-temperature lithium batteries
Low-temperature lithium batteries are widely used in a variety of electronic devices due to their lightweight, high specific energy, and long lifespan. The low-temperature polymer lithium-ion battery also has the advantages of being lightweight, extremely thin, highly safe, easy to modify the storm’s geometric shape, and simple packaging. It has turned into the power hotspot for the vast majority versatile electronic items.
It can still use low-temperature lithium batteries, typically at -50°C, but not ordinary civilian batteries at -20°C. Currently, low-temperature batteries are typically utilized in temperatures below °C. Low-temperature batteries are also required for small power equipment drive power supplies, signal power supplies, military portable power supplies, and communication power supplies. When used outdoors, these power supplies must also perform at low temperatures.
High-performance energy storage power sources, particularly low-temperature lithium batteries, are also required for Chinese space exploration projects like the space flight and moon landing program. because military communication products require communication guarantees at lower temperatures and have stricter requirements for battery characteristics. Therefore, the growth of low-temperature lithium batteries is crucial to the growth of the aerospace and military industries.
Because they are light, have a high specific energy, and last a long time, lithium batteries that work at low temperatures are used a lot. Low-temperature lithium batteries can be used in temperatures below zero because they are made of unique materials and processes.
A low-temperature lithium iron phosphate lithium-ion power battery that can operate at room temperature at a temperature of minus 60°C has been developed by engineers at the University of California, San Diego. At the moment, the two main kinds of low-temperature batteries that it can sell are polymer low-temperature lithium batteries and low-temperature lithium iron phosphate batteries. The technologies for low-temperature batteries of these two types are fairly mature.
Characteristics of an excellent low-temperature lithium iron phosphate battery:
- Discharge at 0.5 C and -40 C, and the discharge capacity is greater than 60% of the initial total; The discharge capacity exceeds 70% of the initial total at -35°C and 0.3°C;
- large temperature range, from -40°C to 55°C;
- At -20°C, the discharge cycle test curve of the lithium iron phosphate battery for low temperatures is 0.2c. There is still a capacity retention rate of over 93% after 300 cycles.
- It can discharge the discharge curve of lithium iron phosphate batteries that operate at low temperatures at temperatures ranging from -40°C to 55°C.
Long-term research and testing led to the development of the novel low-temperature lithium iron phosphate battery. The electrolyte is enriched with raw materials that are exceptionally useful. The battery’s high discharge efficiency at low temperatures is guaranteed by the high-quality raw materials and technology. Low-temperature applications for this lithium iron phosphate battery include military equipment, the aerospace industry, diving gear, polar scientific research, power communication, public safety, medical electronics, and others.If you want more information about low temperature battery so please visit this site http://www.ept-battery.com/
