Ahead of Tesla's Battery Day event, Elon Musk announced that the promised battery innovations from the automaker will experience a delay in "high-volume production," meaning a pushback is likely expected too for upcoming Tesla electric vehicles with more powerful batteries. The production line will start moving possibly in 2022.

Musk is tipped to unveil a new type of battery, developed in-house by Tesla, that will provide an increased driving range on all Tesla EVs but the company CEO already dropped hints the improvements will not be seen too soon. His social media post on the subject pointed to a production delay.

"What we announce will not reach serious high-volume production until 2022," Musk said on Twitter.

Anticipating significant shortages in the years to come, Musk said he will continue working with partners for Tesla's battery needs and the collaboration will be continued beyond 2022. At the same time, the automaker will push with the completion of its in-house battery cells at an accelerated pace.

Engadget said Tesla's decision to purchase batteries from existing suppliers like Panasonic and LG is to ensure that the projected shortages will not greatly impact the release of vehicles that Musk said will be rolling out in the next few years.

Still, Musk already flagged the possibility of release delays and the company chief pointed to some of the hotly anticipated Tesla models such as the Roadster, Cybertruck, and Semi. Musk, however, gave his word that Tesla is taking actions to cushion the impact of the delay.

The projected delay could be attributed to how things are going at Tesla's Fremont facility, where the company's new battery cell technology is believed to be in development. Electrek said the project is a work in progress and adjustments are being made on regular basis.

For instance, the Fremont production line provides new learnings on the technology that Tesla is working on, and from the same data, the company is building the machines required for the targeted manufacturing at a massive scale.

This is expected to continue until the final production line is assembled. Per the same report though, Tesla is seen to achieve a decent output on the new battery cells between the target date mentioned by Musk.

These new batteries could end up being previewed by Tesla on existing vehicles, which could mean that the improvements advertised by Musk will be seen in the future releases of Model S, Model X, and Model Y.

The final cut, however, is likely reserved for Tesla offerings that will make use of the battery technology at an optimal level. And this suggested that while the Roadster, Cybertruck, and Tesla Semi will debut at a later time, it will be worth the wait for these monster EVs.
