High temperature lithium ion batteries can be roughly divided into two categories: lithium-ion metal batteries and lithium-ion batteries. Lithium ion batteries do not contain metal-state lithium ions, and is capable of charging. The fifth generation of the rechargeable battery is born in 1996, its safety, specific capacity, self-discharge rate and performance ratio are better than lithium-ion batteries.
Some large devices and equipment are resistant to high temperature lithium-ion batteries. Because the lead-acid battery is not environmentally friendly, the energy density is low, the volume is large, the life is short, and the weight is heavy, and now the newly developed products of the merchant is basically high-temperature lithium ion battery as an important power supply system. In order to ensure the life and safety reliability of the lithium ion battery, the high-temperature lithium-ion battery pack will adopt advanced protection management systems, prevent overcharge, over-discharge, high temperature operation, low temperature charging, or short-circuit, and even safety question.
The lithium phosphate ion battery is one of the lithium ion battery, which refers to a lithium ion battery with lithium iron ions as a positive electrode material. It is featured that it is strong and stable, high temperature resistance, and good cycle performance. As with the ternary lithium ion battery, the lithium iron phosphate ion battery theory life has only more than 2000 charge and discharge cycles, even if one day is charged, it can still last for more than five years.
Generally, the daily household is three days, and it can also use it for about eight years. However, since the low temperature performance of lithium iron phosphate ion batteries is poor, the life of the lithium iron phosphate ion battery will be relatively longer in the southern region. High temperature resistance advantages compared to ternary lithium ion batteries.
The high temperature performance of the lithium phosphate ion battery is better, and the high temperature of 350c to 500c is resistant, and the lithium manganese acid lithium-ion / cobaltate is usually only 200C, and the material of the modified three-dimensional lithium ion battery is substantially substantially in 200c.
