Tesla planning to ship dry electrode 4680 battery cells by end of 2024: report
A recent report from China has suggested that Tesla is planning to start the mass production of the complete version of its long-awaited and highly-anticipated 4680 battery, which was initially unveiled in September 2020 during Battery Day. The complete version of the 4680 cells will reportedly be produced using Tesla’s dry electrode process.
Citing people reportedly familiar with the matter, Chinese publication LatePost noted that Tesla is planning to mass produce and install 4680 cells with dry electrodes to consumer vehicles before the end of the year. As per the publication, this upcoming version of the 4680 cell would be the battery’s complete iteration.
LatePost‘s sources claimed that the 4680 cells in the Cybertruck today feature a lower-cost negative electrode and a more costly positive electrode. This is reportedly because the negative electrode in the Cybertruck’s current 4680 cells is produced using Tesla’s dry electrode process, but the batteries’ positive electrode is purchased from suppliers like LG and thus produced using more conventional wet electrode processes.
테슬라, 4680 배터리 "완성형" 개발 마지막 승부수
요약:
1. 테슬라는 올해 말까지 완전 건식 전극 방식의 4680 배터리 양산을 계획하고 있습니다. 이는 4680 배터리의 "완성형" 버전이 될 것입니다.
2. 현재 테슬라의 4680 배터리는 음극만 건식 전극을 사용하고 있으며, 양극는 여전히 전통적인… https://t.co/t4CBOK5jyw pic.twitter.com/Pp6TZjfqNc— Oh Hahm Ma *⃣ (@ohmahahm) July 17, 2024
The dry-process positive electrode is reportedly the most difficult part of the 4680 batteries for now, LatePost noted. The positive electrode is also the component that reportedly has the highest cost share in the batteries themselves for now, exceeding 35% of the cells’ overall cost.
Tesla has reportedly finalized the design of the 4680 cells’ dry-process positive electrode, which is a notable step towards the mass production of the batteries’. One of the publication’s sources, who is reportedly a Tesla insider, noted that mastering dry electrode processes could give Tesla some serious momentum. “Once dry electrodes are developed, they can change Tesla,” LatePost‘s source claimed.
Tesla already uses 4680 cells for the Cybertruck, though the output of the batteries for now is reportedly enough for just about 1,000 units of the all-electric pickup truck per week. The Tesla Cybertruck will reportedly be the recipient of the complete version of the 4680 battery cell as well. Once the output of the 4680 cells are optimized, it would not be surprising if the dry electrode batteries also get rolled out to the company’s other vehicles.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.

Tesla expands ridesharing service in California to new hotspot
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.
Our Bay Area rideshare service now goes to SFO ✈️
— Tesla AI (@Tesla_AI) July 21, 2026
Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
