5 tons of reed straw produce half a ton of polylactic acid (PLA)? Lignin-based battery anode materials.

 

 

At the beginning of this year, Zhejiang Canghai Heneng New Materials Technology Co., Ltd. conducted trial production of its 1,000-ton-per-year porous carbon production line, successfully using lignin extracted from crop straw to prepare porous carbon for silicon-carbon anodes. Currently, the company is optimizing the production line in preparation for full-scale mass production.

 

Relying on biorefining technology, this production line can achieve industrial extraction of high-purity lignin from reed straw and use it as a raw material to research and produce lignin-based battery anode materials, turning waste into treasure.

Focusing on the industrialization of silicon-carbon anode materials, the porous carbon materials prepared from lignin precursors offer advantages such as high carbon content, strong pore structure plasticity, and uniform particle size. Their performance metrics comprehensively lead the market's similar products, successfully overcoming the technical bottleneck of silicon-carbon anode carbon skeleton.

It is reported that Zhejiang Canghai He Neng New Material Technology Co., Ltd., jointly funded by Shanghai Hanhe Biotechnology Co., Ltd. and Cangnan State-owned Enterprises in March 2023, focuses on the industrialization of silicon-carbon anode materials. The porous carbon material prepared from lignin precursor has the advantages of high carbon content, strong ductility of pore channels, and uniform particle size. Its performance indicators are comprehensively leading over similar products in the market, successfully breaking through the technical bottleneck of the carbon skeleton of silicon-carbon anode.

5 tons of reed straw can produce half a ton of polylactic acid and half a ton of lignin. The porous carbon derived from lignin is an important material for producing silicon-carbon anodes, which will be used in high-end power batteries and high-end 3C consumer batteries. This means that products such as new energy vehicles, mobile phones, tablets, and laptops will all have to use this material.

 

 

A headquarters for Hanhe Biotechnology New Materials Research has already been established in Cangnan, featuring R&D departments focused on negative electrode materials for batteries, bio-resins and composite materials, and bioplastics. Among these, the research and development achievements in bio-resins and composite materials were industrialized in 2024, mainly applied in composite materials for wind turbine blades and mobile phone backs. The output value exceeded 18 million yuan in 2024.
