We introduce LFP (lithium iron phosphate), LMFP (lithium manganese iron phosphate), and graphene anode materials, which are gaining particular attention as high-performance cathode and anode materials for next-generation lithium-ion batteries.
  • Outline

Primary components of a lithium-ion battery

【Cathode Active Material】
 Examples: NCM (Nickel Cobalt Manganese), NCA, LFP (Lithium Iron Phosphate)

【Anode Active Material】
 Examples: Graphite (natural/artificial), hard carbon, silicon-based materials

【Conductive Additives】
 Examples: Carbon black, CNTs, graphene

【Binder】
 Examples: PVDF, SBR/CMC (water-based)

Features

■ Cathode Active Materials

  1. LFP (Lithium Iron Phosphate)
    High safety: Stable crystal structure that resists thermal runaway, making it ideal for EVs and energy storage.
    Long cycle life: Excellent durability with thousands of charge/discharge cycles.
    Stable supply: Iron-based composition ensures low raw material cost and reduced supply risk.
  1. LMFP (Lithium Manganese Iron Phosphate)
    Higher voltage: The addition of manganese increases operating voltage to around 3.7–4.1 V, compared to 3.4 V for LFP.
    Improved energy density: Achieves higher energy density while maintaining the safety advantages of LFP.
    High thermal stability: Performs reliably across a wide temperature range, suitable for harsh environments.

■ Anode Active Materials

  1. Graphene Anode Materials
    Outstanding electrical conductivity: Single-layer carbon structure provides conductivity dozens to hundreds of times higher than graphite.
    Excellent fast-charging capability: Short Li-ion diffusion pathways enable rapid charging performance.
    Ideal for high-power applications: Enhances instantaneous output in EVs and power tools.
    Also effective as an additive: Used not only as an active material, but also as a conductive enhancer when combined with graphite.
