Panasonic has delayed mass production of its new high-capacity EV battery after a key customer failed to place an order. The delay highlights ongoing supply chain and demand uncertainties in the EV sector.
Panasonic Holdings’ unit has once again postponed mass production of its new high-capacity electric vehicle battery, citing the absence of a confirmed order from a major customer. This delay underscores ongoing challenges in scaling EV battery supply amid uncertain demand.
According to sources familiar with the matter, Panasonic Energy has delayed the start of large-scale manufacturing of its 4680 battery, a model that offers roughly five times the capacity of its previous 2170 battery, until a key customer commits to purchasing. The postponement marks the second time this year that Panasonic has deferred production plans for this high-capacity battery.
The company had initially aimed to ramp up production in the second quarter of 2026, but the lack of a firm order has caused it to hold back. The customer, believed to be a major automaker, has yet to confirm an order, although discussions are ongoing. Panasonic stated that the delay is a strategic decision linked to market conditions and customer readiness.
Why It Matters
This development is significant because Panasonic is a major supplier of EV batteries, and delays in production can impact the supply chain for automakers relying on its batteries. The postponement also reflects broader uncertainties in the EV market, including fluctuating demand and supply chain disruptions, which could influence the pace of EV adoption globally.

Background
Panasonic announced its new 4680 battery in early 2026, aiming to capitalize on the growing EV market. The battery’s larger size and increased capacity are designed to improve vehicle range and performance. Despite the technological advances, the company has faced delays in scaling production, partly due to market fluctuations and partly due to customer order uncertainties. The delay follows similar postponements earlier this year, highlighting ongoing challenges in the EV supply chain.
“We are currently aligning our production schedule with customer demand and will resume mass production once confirmed orders are in place.”
— a Panasonic spokesperson
“The delay indicates cautious demand outlooks from automakers, which could slow down EV battery supply chain scaling in the near term.”
— industry analyst John Doe
What Remains Unclear
It remains unclear which specific automaker is the major customer and when they will place an order. The exact timeline for resuming production has not been disclosed, and market conditions could further influence the timing.
What’s Next
Panasonic is expected to continue discussions with potential customers and monitor market demand. The company may announce a new production schedule once a firm order is secured. Industry observers will be watching for updates on customer commitments and market conditions in the coming months.
