Because lithium-ion batteries are made differently from lead-acid batteries, the failure rate of lithium-ion batteries is much lower.
As the world shifts to electric vehicles to reduce climate change, it is important to quantify future demand for critical battery materials.
Summer many people like to put the lithium ion battery electric cars under the sun insolates, winter also is parked in the yard or road, this is about the service life of lithium ion battery is very bad, the lithium ions in the electrolyte and electrode slice migration rate is closely related to the temperature, the temperature in theory - 20 ℃ to 55 ℃ between can normal use, in daily life, the lithium ion battery temperature between 5 ℃ to 35 ℃ is no harm for lithium ion batteries, lithium-ion battery as much as possible to retrieve the user in the north winter storage in the home, don't to outdoors, southern users to prevent the summer sun.
Lithium ion battery is a necessary power supply for mobile electronic equipment in today's society. It is composed of positive electrode, negative electrode, diaphragm and electrolyte, etc. Its key performance indexes (such as multiplier performance and cycle life) are determined by the electrochemical performance of positive electrode materials.LiFePO4 is recognized as a positive electrode material.
With the development trend of new energy vehicles, the driving force of lithium ion battery technology is also continuing to improve.At present, the single specific energy of lithium iron phosphate battery is 160Wh /kg, the specific energy of the system is 130, the single specific energy of 18650 of the NCA management system has reached 240Wh/kg, and the specific energy of the system software is 150Wh/kg.
Lithium iron phosphate battery and lithium manganese acid, lithium cobalt acid, ternary lithium battery is the same branch of lithium ion battery, its performance is mainly suitable for power application, then called lithium iron phosphate power battery, also known as lithium iron battery.Therefore, the advantage of lithium iron phosphate battery mainly refers to its comparison with other batteries in power application.In this sense, it will be compared with ternary lithium batteries and lead-acid batteries comparative advantages.
