At Xos, we are committed to delivering durable, reliable, and cost-effective electric vehicles (EVs) for commercial applications. A key component of this commitment is our strategic decision to utilize Lithium Iron Phosphate (LFP) batteries in our vehicles.

Why LFP Batteries?

1. Extended Lifespan

LFP batteries are renowned for their impressive cycle life, typically ranging from 2,000 to 4,000 charge-discharge cycles. This longevity translates to approximately 10 to 12 years of regular use before experiencing a 20% reduction in their original capacity.

2. Enhanced Safety

Safety is paramount in commercial vehicle operations. LFP batteries offer superior thermal stability, significantly reducing the risk of thermal runaway compared to other lithium-ion chemistries. This stability ensures that our vehicles can operate safely under various conditions, providing peace of mind to fleet operators.

3. Cost-Effectiveness

The materials used in LFP batteries are more abundant and less expensive than those in other lithium-ion batteries, such as Nickel Manganese Cobalt (NMC) batteries. Unlike manganese and cobalt, which are critical components of NMC cells, the materials in LFP batteries are not subject to the same level of supply chain constraints. Cobalt, in particular, is sourced from regions with fragile and often conflict-prone supply chains, which creates ethical concerns and risks of supply disruptions. Additionally, the extraction of cobalt is associated with significant environmental and human rights issues.

Manganese, while less ethically problematic, still has a more expensive and less stable supply chain compared to the more common materials used in LFP cells. These factors drive up the cost of NMC batteries, making them less attractive for commercial vehicle applications where total cost of ownership is a key consideration. By contrast, the stable and cost-effective supply chain of LFP batteries allows us to offer vehicles with lower acquisition costs, further enhancing the overall economic advantage of electric vehicles for fleet operators.

Our Journey with Battery Technology

Initially, Xos utilized NMC batteries, which were considered state-of-the-art at the time. However, through extensive real-world experience and feedback from delivery fleets, we identified three critical attributes that our customers prioritize:

Durability: Vehicles must withstand the rigors of daily operations, including varying road conditions and driver handling.
Reliability: Consistent performance is essential to avoid downtime and maintain operational efficiency.
Total Cost of Ownership (TCO): Fleet operators seek solutions that offer long-term cost savings over traditional diesel vehicles.

Safety Considerations

While all energy storage systems carry inherent risks, LFP batteries have distinct safety advantages:

Thermal Stability: LFP batteries remain stable at higher temperatures, reducing the likelihood of thermal runaway events.
Mechanical Robustness: They exhibit less swelling under stress and can withstand physical impacts better than some other battery chemistries.

Our transition to LFP battery technology reflects Xos's dedication to meeting the evolving needs of the commercial vehicle industry. By focusing on durability, reliability, safety, and cost-effectiveness, we continue to provide innovative solutions that empower fleet operators to embrace a sustainable and efficient future.
