Why can't the lithium iron phosphate battery for lead-acid batteries?

Source: 2020 - 03 - 29 hits: giving time first, let's talk about the size of the lead-acid battery. Lead-acid battery car battery is the main market, uninterruptible power supply ( UPS) , electric bike and storage power station. In car battery, for instance, lead-acid battery life is about 3 years, and lithium iron phosphate battery calendar life for 5 years, so the lithium iron phosphate battery is definitely a disadvantage on price. In addition, the lead-acid battery much safer than lithium iron phosphate batteries. Finally, because the freyliu remind, low temperature lithium iron phosphate engine now didn't get good treatment. In the case of UPS, lead-acid battery market has been steadily eroded. While lead-acid battery only for small UPS, but the proportion of medium and large UPS lithium iron phosphate battery is increasing. From the start of last year, China mobile, netcom, telecom communication base station of battery has already started to all use lithium iron phosphate batteries. As base station using UPS, the price advantage of the lithium iron phosphate, one for the lithium iron phosphate battery for high temperature tolerance is better than that of lead-acid battery, can save the cost of temperature control. The use of electric bikes, the price of lithium iron phosphate battery bike and lead-acid battery bicycle price gap is very big, choose in the hands of consumers, and bicycle battery quality is uneven, ran a few tens of kilometers of the state of the battery capacity attenuation is not a lot. In terms of energy storage power station, the lithium iron phosphate batteries are completely crushed the lead-acid battery, but it is not completely meet the energy storage technology of grid level, can only say that in a short out. Finally, the production of the lithium iron phosphate is patented in foreign countries, this is also the foreign electric car widely used ternary cathode material is one of the reasons for lithium battery. The life of the lithium iron phosphate battery is not necessarily 4 - longer than lead acid battery Five times the current lead-acid battery technology content is relatively high, 5 years of age is no problem. However, because of the anode material graphite structure collapse, even without the use of five years, lithium batteries will also be give up. Batteries of different quality can't compare, digititan and also far east. Do not pollute the environment more than lead-acid batteries, lithium-ion batteries but certainly not environmental protection.
