What are the important characteristics of lithium batteries

Reliability and availability Due to the different manufacturing methods of lithium batteries and lead-acid batteries, the failure rate of lithium batteries is much lower. Due to the longer service life and lower maintenance requirements, the use of lithium batteries for UPS power supplies rarely fails. Depending on the chemical composition used, the service life of lithium batteries can be as long as 15 years. Compared with lead-acid batteries, it can significantly save replacement costs, because lithium batteries do not have to be replaced every few years. In addition, lithium batteries generally have a longer cycle life than lead-acid batteries. For example, a lead-acid battery can usually supply 200 discharge cycles, which means that the capacity of the battery can be depleted to 50% of its rated value, and then it can be recharged to 100%, which can reach 200 cycles. But before replacing the battery, the lithium battery can supply 500-7000 discharge cycles (depending on the chemical substance used). In addition, lithium batteries have a low self-discharge rate, or self-discharge slowly when not in use, which makes them have a longer storage time. Lighter weight Lithium batteries are about one-third heavier than lead-acid batteries. This can save data center construction costs, because the floor is not reinforced to bear more weight. It also saves transportation costs because more lithium batteries can be transported at the same cost compared to lead-acid batteries. The size of a smaller-volume lithium battery cabinet is usually half of that of a lead-acid battery cabinet. Reaching the same capacity can save 50% of the floor space. This allows organizations to re-plan and design data centers to increase the available space for IT systems. In addition, the construction cost of the new data center can be saved because the space for accommodating the lithium battery cabinet for UPS energy storage can be smaller. Higher energy density Lithium batteries have higher energy density (Wh/kg, or watt-hours per kilogram) and power density (W/kg, or watts per kilogram). This is why lithium batteries can supply the same energy as lead-acid batteries with a smaller volume and lighter weight. Working in a higher temperature environment, lithium batteries can work at 86°F (30°C), which is nearly 10°C higher than lead-acid batteries. This allows organizations to increase the room temperature in the data center, thereby saving power for cooling, reducing cooling costs, and saving total cost of ownership (TCO). In addition, lithium batteries are not very sensitive to temperature changes, and excessively high temperatures will obviously not shorten the service life of the battery. Reduce maintenance Lithium batteries are equipped with a built-in battery management system (BMS), which can provide monitoring and maintenance functions such as automatic status, fault monitoring, battery balancing, power optimization, and external communication. The battery management system (BMS) enables data center facility engineers to more easily monitor battery operating hours and health, reduce labor and maintenance costs, and significantly reduce the risk of battery pack failure. Faster charging Lithium batteries are fully charged in about two hours, while lead-acid batteries are fully charged in about 24 hours. Faster charging time means that lithium batteries can better deal with multiple power outages. (For example, if there are multiple power outages within 24 hours, lithium batteries can be charged faster, providing complete UPS backup power time for each outage.) Environmental advantages The carbon footprint of lithium batteries is one-third of that of lead-acid batteries One, and more environmentally friendly.
