Outdoor power Q&A: Outdoor energy storage power with what cell?

The volume of outdoor energy storage power is smaller and smaller, but the capacity and power are larger and larger, providing better protection for outdoor activities. Outdoor UPS energy storage power supply can also power a variety of photographic equipment and props in the studio, including cameras, monitors, audio, radio equipment, table lamps, etc. When you're not filming in the car, you can cook and make coffee outside.

The performance indexes of power battery mainly include energy storage density, cycle life, charging speed, resistance, temperature and safety, among which energy storage density and safety are the two main requirements of outdoor energy storage power supply.

There are six commonly used energy storage power sources, which are aluminum-rich lithium battery, lithium manganese acid battery, lithium titanate battery, lithium iron phosphate battery, lithium terene battery, lithium cobalt battery

Lithium manganate batteries and lithium titanate batteries were the first to be kicked out due to their low energy storage density, and lithium cobaltate suffered the same fate due to its poor safety, leaving only lithium aluminum-rich batteries, lithium iron phosphate batteries, and lithium terpolymer batteries to enter the energy storage market. But lithium aluminum-rich batteries, despite their high safety factor and excellent parameters, But the price is so high that many companies don't use outdoor energy storage; And all kinds of properties are good lithium iron phosphate battery, three-way lithium battery has become the outdoor energy storage power supply commonly used two types of cell.

Lithium iron phosphate battery, ternary lithium battery is also different; Here is to give you popular science;

The first is high safety, because the thermal runaway temperature of lithium iron phosphate battery is generally above 500 degrees, and that of three-way lithium battery is below 300 degrees. Compared with lithium iron phosphate battery, the risk of spontaneous combustion in the process of use is lower.

The second is longer cycle life, because the charge and discharge cycles of lithium iron phosphate battery are greater than 3,500 times before they begin to decay, that is to say, its service life can be as long as about ten years, but the charge and discharge cycles of ternary lithium battery are only 2000 times, meaning that its service life is only 6 years, such a more intuitive comparison of time length, Will give you a more direct sense of the advantages of lithium iron phosphate cell.
