Recently, see some solar street lamp manufacturers claim ignorance of the lithium iron phosphate battery products are good, so much so much obtained country patent, resistance to high temperature, and low temperature resistant, propaganda, fantastic it is completely without obligation to the customer with the product don't understand, so what is the distinguishing feature of lithium iron phosphate battery, what is the difference with the ternary lithium battery?
Well-known, lithium battery had become the development trend of solar lamps and lanterns industry, compared with the traditional battery is convenient, environmental protection, high cost performance, the current market commonly used lithium battery is divided into three lithium battery and lithium iron phosphate battery two kinds. LED street lamp it is a kind of efficient solid state light source based on semiconductor PN junction formed with weak electric energy can emit light, in a certain forward bias voltage and injection current, injected into the hole in the P region and injected into the N region of electrons in the diffusion to the active region after radiation compound and emit photons, the electric energy directly into light energy.
It is a solid cold light source, with environmental protection, no pollution, less power consumption, high light efficiency, long life and other characteristics, therefore, LED street lighting will become the best choice for energy-saving transformation. This article, let's compare the advantages and disadvantages of lithium iron phosphate battery and ternary lithium battery used in solar street lamps:
01, service life: the cycle of lithium iron phosphate battery is about 1500-2000 times, can be used for 8-10 years; Ternary lithium battery cycle number of about 300-500 times, the absolute difference in the market lithium battery cycle number of only 200 times, only pure three can reach 500 times cycle, life of about 3 years.
02, fastness (safety) : the fastness of lithium iron phosphate battery is high, and our company uses high-efficiency energy lithium iron phosphate battery is more firm. The proportion of three yuan lithium batteries on the market is not firm, such as high manganese content is more likely to produce trouble, such as fire and explosion.
03, warranty period: individual ternary lithium battery warranty for one year, lithium iron phosphate battery warranty for three years.
04, environmental temperature request: lithium iron phosphate battery can withstand high temperature up to 70℃, but low temperature discharge effect is poor, in low temperature areas we need to do a good job of leveling and increase battery heating equipment. Solar street lamp LED lamp head wire lithium control battery white cap separated, wiring attention to use electrical tape wrap. The wiring on the back of the solar panel is reverse buckle design, which can be gently pried open with a screwdriver. The wiring of the solar panel (red cap is connected to the positive pole line, black cap is connected to the negative pole line) corresponding to the positive and negative pole line separated from the black cap of the lithium integrated battery, and the wiring should be wrapped with electrical tape. And ternary lithium battery is minus 15℃ - 50℃.
