VDL is pleased to announce that the company has recently been granted rechargeable coin battery patent from numerous countries and regions including US, Europe, Japan and India. The patents are based on VDL’s China patent published in 2018, which protects the use of stacking technology in coin battery manufacturing process. The growing patent family is a testament of VDL’s strong emphasis on technology innovation and help VDL better response to the growing competition in the booming rechargeable coin battery industry.
Nowadays most of the rechargeable coin battery manufacturers are adopting winding technology in their production process. However, these winding battery makers have the potential risk of infringing the global patents filed by Varta-Microbatteries and may pose tremendous legal dangers to the end users of these batteries.
VDL’s stacking technology, on the other hand, is an innovation invented by VDL, and since it differs significantly from winding technology, it offers legal risk free battery solutions to our end customers. In 2020, we will continue the expand of our global patent portfolio to constantly provide our customers with the industry-leading micro batteries.
