Recently, the emerging “dry battery electrode” (DBE) technique has provided promising prospects for the battery industry. The dry electrode exhibits unique advantages compared with the conventional wet coating methods due to the non-solvent process that include environmental friendliness, low cost, enh...
On February 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 addi...
The objective is to discover how to create processable mixes with scalable technologies that can result in a homogeneous electrode coating. At the particle level, this involves managing the distribution, packing, and contact between various electrode materials. Creating the desired homogeneity is a sign...
The dry process could offer a variety of benefits to manufacturers and the U.S. supply chain: It’s highly compatible with current state-of-the-art electrode manufacturing equipment, while its reduced environmental impact makes battery plants suitable in more places. ...
If desired or convenient however, the battery may be assembled in the reverse order by placing 1 first a zinc plate without a carbon coating, then electrolyte and paper 8, tablet 7 and duplex electrode with carbon coating downwards, repeating with electrolyte tablet 7 and duplex electrode until...
