1mm Ultra Thin Lipo Battery 013040 3.7v 70mah 80mah Lithium Polymer Battery For Gift Card

This high discharge lithium polymer battery achieves a precisely controlled thickness of 1.0mm, enabling seamless integration into space-constrained thin devices such as smart cards, ultra-slim remote controls, or wearable medical patches.

Moreover, its packaging structure supports flexible non-rectangular shape customization — including round, C-shape, concave, L-shape, and other irregular contours — allowing it to conform tightly to unconventional internal cavities. This maximizes the utilization of residual space to increase capacity or optimize heat dissipation without increasing overall device thickness.

In a home environment, this high discharge battery is particularly suitable for devices that require short bursts of high current. Typical use cases include:

• Cordless Vacuum Cleaners – When switching to turbo mode, the battery can instantly output >30C current, ensuring rapid motor speed increase without suction loss.
• Electric Toys & Hobby Models – Such as RC cars and drone toys; high discharge rates provide aggressive acceleration response and stable climbing power.
• Power Tools – Handheld drills and electric screwdrivers maintain voltage during high-torque fastening, preventing tool stalling.
• Jump Starters – Supplies instantaneous high current to start 12V gasoline engines reliably.

Compared to standard energy cells, high discharge batteries significantly reduce voltage sag and self-heating under heavy loads, enhancing both user experience and safety in household applications.

To achieve long cycle life even under high rate discharge, this battery adopts advanced material technologies:

• Multi-layer composite cathode material (modified NMC) with nano-coating to reduce lattice collapse
• High-porosity, low-impedance separator for optimal ion flow
• Mesocarbon microbeads (MCMB) or carbon composites for rapid lithium ion accommodation
• Dual-functional additives in electrolyte to form dense SEI layers
• Multi-tab design distributing current uniformly and reducing local current density by over 40%

These innovations enable the battery to retain >80% of initial capacity after 300 cycles of 15C continuous discharge — far exceeding conventional high discharge cells.

High-Temperature Design: The battery employs ceramic-coated separator (shrinkage <2% at 150℃) and high-decomposition-temperature electrolyte. Combined with enhanced PP layer in the aluminum-laminated film, internal gas generation is reduced by 70% during continuous discharge at 60℃, effectively preventing heat-induced bulging.

Stable Low-Temperature Performance: For -20℃ environments, the electrolyte uses low-viscosity solvents and dual lithium salt system, maintaining ionic conductivity above 8 mS/cm even at low temperatures. The battery delivers over 70% of its room-temperature capacity at -20℃ with 5C discharge rate and no lithium plating.
