Tesla has published a new patent for battery storage and the contents are potentially very significant to Tesla’s mission to produce long-range, lower cost electric vehicle batteries that will last as long as its electric vehicle hosts.

The new patent – originally filed in No vember last year, but only published this month – describes a “tabless electrode” that does away with the tabs that connect the positive and negative terminals of a jelly-roll battery. The goal is to reduce resistance and manufacturing costs.

Tesla will soon host a Battery Day, currently slated for the third week in May, and when questioned regarding what will be revealed during this highly anticipated event at the company’s Q1 2020 earnings call, Musk foreshadowed news of some significance:

“We want to — leave the exciting news for that day, but there will be a lot of exciting news to tell. And I think it would be one of the most exciting days in Tesla’s history and we’re just trying to figure out the right timing for that.”

Now, Musk has responded on Twitter to news regarding the latest in a string of battery-related patents, advising that this latest patent filing is “way more important than it sounds.”
