​​​​​​處鋰科技團隊鑽研電池材料回收技術成果不斷;今年成功從電動車及儲能電池中回收石墨材料,透過自主獨特專利技術將石墨材料分離,並導回電芯製造源頭,生產新電芯;全新石墨回收技術3月下旬甫獲第二十七屆俄羅斯阿基米德國際發明展競賽金牌,再度在國際發明展擦亮MIT招牌。

處鋰科技表示,創新的鋰電池負極石墨材料回收技術所回收的石墨粉材具有多項相對優勢;首先在經濟方面,由於石墨礦掌控於特定地區,因此天然石墨取得不易,帶動人造石墨的市場價格上揚,成本較高,若能將廢棄鋰電池中的負極石墨進行回收再利用,將可有效解決石墨材料來源問題。處鋰科技團隊擁有石墨回收技術的獨特性,以及回收成本的明顯競爭優勢,可有效降低下游電芯廠的石墨材料成本。

Secondly, an important and challenging issue for reusing recycled graphite in lithium-ion batteries is graphite purity. Battery-grade graphite must reach 99.9% purity; currently the graphite recycled by 處鋰科技 has tested as high as 99%, indistinguishable from new graphite, and finished cell product testing has been completed.

Being environmentally friendly is also a major feature of 處鋰科技’s graphite recycling and reuse. Because it uses an “enzymatic degradation” technique, 處鋰科技 conducts the entire graphite recycling process in a non-toxic, environmentally friendly manner that does not impose any burden on the environment.

處鋰科技 chairman 陳文賢 pointed out that under the net-zero carbon emission trend, global demand for recycled materials is growing daily. In 2027 the EU will require imported electronic products to include a certain proportion of recycled materials. The emergence of 處鋰科技’s recycled graphite materials is timely: it both lowers production costs and reduces dependence on imported graphite raw materials, further enhancing the competitiveness of local lithium cell manufacturers.

In addition to the major breakthrough in recovering anode graphite materials, 處鋰科技 has also made clear progress recently in recovering cathode materials, with recovery content reaching over 3%. It is arranging to produce cells from recovered cathode powder and recovered anode powder and to carry out electrical characteristic testing.

陳文賢 emphasized that 處鋰科技’s successful recovery of recycled cathode and anode materials from lithium batteries will greatly boost competitiveness for collection/storage operators and cell manufacturers; purifiers can obtain recycled materials without other impurities, reducing purification costs, while the separate recovery of cathode and anode powders lowers cell manufacturers’ production costs and helps keep strategic materials in Taiwan.
