特斯拉的新电池:干电极(DBE)涂层技术,又称dry battery electrode (DBE) coating technology:是将少量(约5-8%)细粉状粘合剂(PTFE)与正极、负极粉末混合,通过挤压机形成薄的电极材料带,压到金属箔集流体上形成电极。该技术特点是工艺过程简单、电极更厚、无溶剂化 ...
In view of these shortcomings, researchers proposed another technique known as dry electrode coating technology. This technique has several advantages over wet coating technology, like avoiding toxic solvent usage, having a better discharge rate, and easy manufacturing. This review envisaged to discuss ...
一般来说,电极的制造过程如下,制备电极浆料(electrode slurry),涂布与干燥(coating and drying),辊压(calendaring),极片分切(electrode slitting),隔膜分切(separator slitting),卷绕(winding),注液(electrolyte filling),包装(packaging),老化和化成(aging and formation),分拣和检查(sorting and inspection)。如图1所...

Maxwell Technologies is actively engaged in this global effort from the direction of dry electrode fabrication technology. Maxwell dry electrode technology offers manufacturing cost and performance competitiveness, and novel battery chemistry enablement. This paper provides the initial foundation and validation...
To address such issues, we employ a dry-processed electrode technology utilizing a polytetrafluoroethylene (PTFE) binder in this study. The effect of PTFE particle size is explored using cryogenic pulverization to reduce PTFE resistance and evenly distribute it. Tuning the PTFE particle size to a ...
OnFebruary 6, 2025, Matthews announced the favorable ruling in arbitration against Tesla, which reaffirmed the Company’s right to sell its proprietary dry battery electrode technology (“DBE”) to customers around the world. Since that date, Tesla has responded by filing two additi...
By contrast, IBE arrangements are based on a tripode configuration, in which the substrate is placed on a third electrode and is decoupled from the plasma source (termed in this case “remote plasma”). The IBE process is carried out in the presence of a noble gas, typically argon, which...

The commercial coating way of lithium-ion batteries has generally used wet coating technology so far. However, N-Methyl-2-pyrrolidone (NMP) is a toxic and expensive organic solvent using in this wet electrode manufacturing process, which is not environmentally friendly and greatly increases the cost...
