Energy storage batteries typically use either lithium batteries or lithium iron phosphate batteries

Energy Storage Batteries: Lithium Batteries or Lithium Iron Phosphate Batteries?
In the booming global energy storage market, a common question arises: should we choose general lithium batteries or lithium iron phosphate (LFP) batteries for energy storage? The answer is clear: ”lithium iron phosphate batteries are the absolute mainstream for energy storage applications”. It is worth noting that lithium battery is a general category, which includes LFP batteries, ternary lithium batteries and other subtypes. Ternary lithium batteries are only adopted in a few special scenarios. As a leading brand in the industry, Redway Power focuses on LFP technology and delivers safe, long-lasting and cost-effective energy storage solutions to clients worldwide.

1. Concept Clarification: Lithium Batteries vs. LFP Batteries

Many people confuse the two concepts. ”Lithium battery is an umbrella term” classified by cathode materials, mainly including ternary lithium batteries (NCM/NCA), lithium iron phosphate batteries and lithium manganate batteries. ”LFP battery is an important branch of lithium batteries”, named after its lithium iron phosphate cathode material, and it has become the top choice for modern energy storage systems.

2. Why LFP Batteries Dominate Energy Storage

Energy storage batteries prioritize safety, long cycle life, stability and low cost — all strengths of LFP batteries, which outperform ternary lithium batteries in core indicators.
2.1 Superior Safety
LFP features an extremely stable crystal structure with a thermal runaway temperature above 270°C. It rarely catches fire or explodes even under puncture or extrusion, making it ideal for large-scale energy storage clusters. By contrast, ternary lithium batteries reach thermal runaway at around 200°C and carry higher fire risks when damaged or overheated, failing to meet safety standards for large energy storage stations.

2.2 Extended Cycle Life
Energy storage systems require frequent charge and discharge on a daily basis, with an expected service life of 10 to 15 years. LFP batteries achieve 4,000 to 6,000 charge-discharge cycles, and premium models can exceed 8,000 cycles. Ternary lithium batteries only last 2,000 to 3,000 cycles, suffering rapid capacity decay from frequent use and poor long-term economic efficiency.

2.3 Lower Overall Cost
Free from expensive precious metals such as cobalt and nickel, LFP batteries enjoy stable raw material prices and a 15%-20% lower manufacturing cost than ternary lithium products. Calculations show that the Levelized Cost of Electricity (LCOS) of LFP energy storage systems is 18%-23% lower over a decade, effectively shortening the return period of energy storage projects.

2.4 Market Performance
In 2023, LFP batteries accounted for 92.3% of newly installed electrochemical energy storage projects in China. Globally, LFP batteries take up over 80% of the market for residential, commercial & industrial and grid-scale energy storage. Ternary lithium batteries are only used in niche areas such as high-end drones and small energy storage devices for extremely cold regions.
