Lithium batteries will be replaced by colloid lead-acid batteries in terms of the current market, the trend of lithium battery of solar street light
, in recent years gradually occupy the dominant market, scale has been on the rise, the main reason is because the several advantages of lithium-ion batteries 1, decided by the environmental protection of traditional colloid lead-acid batteries contain large amounts of lead, the environmental pollution is visible, the lithium battery has quite a good environmental performance, lithium battery for long term ecological protection is better than colloidal battery.
2, the service life of the ordinary colloidal battery if to 0.
5 and 0 c discharge.
15 c charging, service life is only 350 times, and even a 1 c for charging and discharging lithium battery, service life can reach more than 500 times, visible lithium battery is much higher than the life of a colloid lead-acid battery.
3 of the same capacity lithium battery, weight lighter weight not only a third of the colloid lead-acid battery, this gives colloidal battery can make integrated solar street light has created good conditions.
4, large flow discharge lithium batteries to 1.
5 c working ratio, almost does not affect the service life and capacity, lead-acid battery if the gel to 1.
5 c ratio, life will be reduced to 30%
5, lithium battery charging time short lithium battery can undertake large flow charge, charge time in 4 -
5 hours to complete, and colloid lead-acid battery charging, need below rated charging voltage, charge need 6 -
8 hours, the sun is not strong, often need to 2 -
3 days to get fully charged battery.
6, resistant to low temperature lithium battery to be able to work normally, 25 degrees below zero and lead-acid battery at the time of ten degrees below zero, only half of the original capacitance, it is 25 degrees below zero, can't work normally.
7, lithium battery price is similar to colloid lead-acid batteries, solar street lamp
s for lithium battery discharge depth is deep and half capacity lithium battery and colloid lead-acid batteries, so in the case of the same effect, the advantages of lithium battery will be more, generally choose the lithium battery as energy storage device of solar street light.
To sum up, from environmental performance, such as theory, or from the use of performance, the advantages of lithium battery were significantly higher than the ordinary colloid lead-acid batteries, therefore in the use of solar energy street lamp, lithium battery will be able to replace colloidal battery, becoming the mainstream battery solar street lamps in the future.
