Lithium is green. Over time, lead acid batteries are prone to structural decay. If disposal is managed improperly, toxic chemicals enter and damage the environment. Lithium batteries don’t degrade, making proper disposal simpler and more environmentally friendly. Lithium’s improved efficiency also means fewer units are required to meet power needs, minimizing product waste and further reducing its ecological footprint.
Lithium is safe. While any battery is subject to thermal runaway and overheating, lithium batteries are manufactured with more safeguards to reduce fires and other contingencies. Additionally, the development of newer lithium technologies incorporating phosphorous has improved the technology’s safety profile even more.
Lithium is speedy. Lithium batteries charge faster and more efficiently than lead acid batteries. Most lithium units are able to charge to full in one session, whereas lead acid charging is optimal over multiple, staggered sessions that require attention and drain time. Lithium-ion requires fewer charging sessions in general, able to provide more power per full charge than lead acid.
Lithium discharges rapidly. Lithium’s high discharge rate allows it to provide more power in a given time than its lead acid counterpart and last significantly longer. A cost comparison of lithium and lead-acid batteries in automotive found for the same cost of implementation, lithium batteries went far longer (5 years) without needing replacement vs. lead-acid (2 years).
Lithium is efficient. An average lead acid battery operating at 80% DOD achieves 500 cycles. A Lithium ion phosphate operating at 100% DOD can achieve 5000 cycles before reaching 50% of the original capacity.
