Lithium battery advantage?

The common cell types on market basically has two kinds, one kind is lead-acid batteries, the other is a lithium battery. Higher lithium battery power in the eyes of people, why?

battery energy density:

in the energy density of batteries, lead-acid battery energy density of about 50 & ndash; 70 wh/g, and lithium battery energy density in 200 & ndash; 260 wh/g, that is to say, the two pieces of battery in the case of the same weight, the discharge efficiency of lead-acid battery and battery life is no lithium battery high.

the service life of the battery:

the lithium battery is now the most popular of lithium iron batteries and ternary lithium battery. For lithium iron batteries, it cycles can reach 2000 times, three yuan is slightly inferior to the lithium iron batteries, lithium-ion batteries but it cycles can be reached more than 1000 times, but the lead-acid battery cycle too thousand times all have no, only 300 - 350 times or so. So in contrast, the service life of lithium-ion batteries is 3 - lead-acid batteries About 6 times. If you use lead-acid batteries, will face a dilemma frequently change the battery.

the battery's security:

the safety of new energy is the focus of a lot of people, why lead-acid battery is not used, because if the charging time is too long, it will generate large amounts of hydrogen and oxygen, these gases if not in time, in case of fire will cause explosion. The lithium battery or safer in this respect.

the place on put together is narrated, lead-acid battery is not used or because it is not suitable for the present stage of development, all aspects of performance are not lithium battery is good, the only advantage is cheap more durable. But the market needs is has the development potential of the battery, so the lithium battery to gradually replace lead-acid batteries.
