Hey, dear friends, let’s talk to you today about the two battery giants in electric equipment - lithium batteries and lead-acid batteries. Why have lithium batteries become so popular and become mainstream? Gravimetric energy density From the perspective of gravimetric energy density, lithium batteries have higher energy density than lead-acid batteries. Lithium batteries are famous for their lightweight characteristics and can store more energy under the same weight. Currently, the energy density of lithium batteries is generally 200~260wh/g, and lead-acid is generally 50~70wh/g. The weight energy density of lithium batteries is 3~5 times that of lead-acid, which means that under the same weight, the capacity of lithium batteries is three to five times stronger than that of lead-acid batteries. Therefore, lithium batteries have absolute advantages in energy storage. This means it can provide longer runtimes or drive more powerful devices. Lead-acid batteries, on the other hand, require more weight to store the same amount of energy due to their lower energy density. Volumetric energy density In terms of volumetric energy density, lithium batteries also have an advantage. In comparison, lithium batteries have higher energy density, lead-acid batteries are 30WH/KG and lithium batteries are 110WH/KG. The biggest advantage of lithium batteries is that they have relatively high energy and high storage density, which has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. This means that the relatively small size of lithium batteries can provide higher energy storage capacity, which makes lithium batteries very suitable for equipment with limited space requirements, such as the Ai drive integrated rod of Kucha modular forklift, drones, portable electronic devices, etc. In comparison, lead-acid batteries do not provide the same level of energy storage due to their larger size. Service life In terms of service life, lithium batteries also have obvious advantages. Lithium batteries can be charged and discharged thousands of times, even tens of thousands of times, and can maintain low energy loss during the cycle. Lead-acid batteries have a relatively low cycle life and often need to be replaced more frequently after being used for a period of time. Price In terms of price, lithium batteries are relatively high. This is because the manufacturing process of lithium batteries requires advanced technology and higher costs, while lead-acid batteries are a relatively mature and cheap technology. However, with the development of lithium battery technology and market expansion, its price has gradually declined, gradually approaching that of lead-acid batteries. Applicability From the perspective of applicability, lithium batteries have a wide range of application scenarios. The high energy density and lightweight nature of lithium batteries make them ideal for mobile devices. Lead-acid batteries are suitable for applications that do not require high performance, such as emergency power supplies, low-power tools, etc. Moreover, lithium batteries have strong adaptability to high and low temperatures and can be used in an environment of -20°C to 60°C. After processing, they can be used in an environment of -45°C. The self-discharge rate is very low, which is one of the most outstanding advantages of this battery. It can generally be less than 1%/month. National policies In addition, national policies are also promoting the development of lithium batteries. Due to the high efficiency and environmental protection characteristics of lithium batteries, no matter whether they are produced, used or discarded, they do not contain or produce any toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium. Many countries have formulated policies to support the development of lithium battery technology, including financial support, tax reduction measures, etc. This kind of policy support helps promote the innovation and application of lithium battery technology and further promotes the development of lithium batteries. To sum up, in summary, lithium batteries have won the competition with lead-acid batteries by virtue of their advantages in weight energy density, volume energy density, service life, applicability, and national policies. This is also the reason why Kucha modular forklifts use lithium batteries, and Kucha modular forklifts use A-class batteries, which are safer and more reliable. You can choose 48V10AH or 48V15AH or 48V20AH batteries according to different battery life requirements. With technological advancement and cost reduction, lithium batteries will continue to play an important role in various application fields in the future.
