Battery Technology Comparison
Ternary Lithium Batteries (Li(NiCoMn)O₂)
  • Preferred choice for high-performance applications
  • Energy density approximately 1.5 times that of lithium manganese oxide
  • Smaller size and lighter weight for same capacity
  • Higher discharge rate meets instantaneous high current demands
  • Longer cycle life with lower long-term operating costs
  • Superior low-temperature performance
Lithium Manganese Oxide Batteries (LiMn₂O₄)
  • Ideal for low-cost basic applications
  • Raw materials are readily available and priced stably
  • Superior safety with better thermal stability
  • Strong compatibility with existing power management circuits
  • Basic low-temperature performance meets standard requirements
Main Applications
  • Smart wearable micro devices: Small smart bracelets, children's GPS watches, mini motion trackers
  • Miniature digital devices: Bluetooth headsets, voice recorders, MP3 players, miniature cameras
  • IoT miniature terminals: Wireless sensors, RFID smart tags, data collectors
  • Portable medical devices: Blood glucose meters, pulse oximeters, miniature massagers
  • Small toys and models: Remote control cars, drones, miniature robots
  • Miniature backup power: Smart door locks, emergency power for small electronics
