The Advantages of LFP Lithium-Ion Battery Storage

At POWR2, every decision we make is driven by one vision – a world powered by sustainable energy. That includes the type of battery we use in our products. POWR2 POWRBANKs use lithium-Ion battery storage technology called Lithium-Iron Phosphate (LFP). Let’s explore the benefits of LFP as compared to another type of lithium-ion battery, called NMC, and Lead-Acid options. It’s easy to understand why LFP is the clear choice for POWR2 and our customers.

Battery Technology Runtime and Capacity

LFP batteries can deliver thousands of charge-discharge cycles while maintaining their capacity and performance. In contrast, lead-acid batteries have a limited cycle life, requiring more frequent replacement and resulting in higher operational costs. Lead-acid only offers a 50% depth of discharge, while lithium-ion batteries can use 80 to 90% of their capacity.

One of the major benefits that makes LFP the clear choice for POWR2 and our customers is longevity. LFP offers three times the lifespan over NMC and nearly 20 times the cycles of lead-acid.

Lithium-Ion Battery Storage Safety and Toxicity

Lithium-ion battery storage, both LFP and NMC, offer low toxicity as compared to the relatively high toxicity of lead-acid batteries. Unlike lead-acid batteries, which contain toxic materials such as lead and sulfuric acid, LFP batteries are non-toxic, making them more environmentally friendly.

In addition to longevity, LFP also breaks away from NMC in thermal runaway. That’s the temperature at which batteries start to melt or catch fire. Compared to NMC, LFP batteries have a lower risk of thermal runaway, putting them at a lower risk of fires or explosions.
