Lithium Battery Anode Pre-carbonization Furnace

Lithium Battery Anode Pre-carbonization Furnace

A specialized pre-carbonization solution for lithium battery anodes (pitch coating), graphite, and PI films. Operating at 400-950°C, the furnace is equipped with a dedicated tar collection and tail gas system. It utilizes 30-stage programmable heating curves to precisely manage volatiles, significantly improving the initial coulombic efficiency (ICE) of anode materials.

Product Overview

This series of pre-carbonization furnaces is designed for the research and mass production of new energy materials. It is an essential pre-treatment step for graphite, coke, and PI films before high-temperature graphitization. Addressing the organic volatiles generated during carbonization, the furnace features a corrosion-resistant water-cooled seal and a specialized tar trap, ensuring a stable, eco-friendly process without the risk of clogging.

Key Advantages

  • Anode Performance Boost: Precisely controls heating rates for pitch-coated anode particles, ensuring smooth volatile discharge to improve initial coulombic efficiency (ICE) and cycle stability.
  • PI Film Quality Control: Provides excellent thermal uniformity during PI film stacking carbonization, controlling shrinkage to ensure flat, wrinkle-free carbonized films.
  • Eco-friendly & Stable: Equipped with a large-capacity tar trap to prevent pipe clogging, significantly extending maintenance cycles and reducing emissions pressure.
  • Process Flexibility: Supports 30-stage curve programming for slow-heating de-tarring processes. Capacities ranging from 50L to 2000L are available to meet various production scales.
