Our current daily life of the common aerial work platform is divided into electric power and diesel power, gasoline power and other power modes, which electric power by a part of the customer's favourite; electric power to do power with the battery, the common choice of battery and lithium batteries and lead-acid batteries; lithium batteries and lead-acid batteries in the field of energy storage has a pivotal position, who can not completely replace who, but the two battery Focus is obviously not the same, lead-acid batteries are more inclined to electric bicycles, motorbikes, etc., while lithium batteries are more common in cars. So which is better, lithium battery or lead-acid battery? Compare the advantages and disadvantages of lithium batteries and lead-acid batteries from the following aspects.
1, weight energy density
The current lithium battery energy density is generally 200 ~ 260wh / g, lead-acid is generally 50 ~ 70wh / g, then the weight energy density of lithium batteries is lead-acid 3 ~ 5 times, which means that the same capacity, lead-acid batteries are lithium batteries 3 ~ 5 times, so in the lightweight energy storage devices, lithium batteries occupy an absolute advantage.
2. Volumetric energy density
The volumetric capacity density of lithium battery is usually about 1.5 times that of lead-acid battery, so in the case of the same capacity, lithium battery is about 30% smaller than lead-acid battery.
3,Use cycle
Currently the more popular material system is ternary and lithium iron, ternary power lithium battery cycle times are usually more than 1,000 times, lithium iron phosphate battery cycle times are more than 2,000 times, the lead-acid battery cycle times are usually only about 300~350 times, so the service life of lithium batteries is about 3-6 times as long as the lead-acid battery.
4, Price
At present, lithium batteries are more expensive than lead-acid batteries, about 3 times more expensive, but combined with the service life of the analysis, put the same cost, still lithium batteries to use a longer cycle.
5,Applicability
Lithium batteries are slightly worse than lead-acid batteries because of safety, so in use need to do a variety of safety precautions, such as preventing external forces or accidents caused by damage to the lithium battery, which may cause a fire or an explosion; the current temperature applicability of lithium batteries is also very good, so in terms of other adaptability, lithium batteries are no less than lead-acid batteries.
6,National policy
Lead-acid batteries because of the production process or waste batteries on the environment caused by the harm is quite serious, so from the national policy direction, has been in the lead-acid batteries to limit the expansion of re-investment, or in some areas to limit the use of lead-acid batteries, lithium batteries to replace lead-acid batteries in the future trend will become more and more obvious, and the progress will be gradually accelerated.
Therefore, both lead-acid batteries and lithium batteries, or different materials compared to lithium batteries, they have their own advantages and disadvantages, we can not simply use "good" or "bad" to define. In the purchase of aerial working platform, according to their own actual situation to purchase.
