TL;DR
Panasonic’s unit responsible for manufacturing EV batteries has delayed mass production again, citing pending customer orders. The delay underscores ongoing supply chain uncertainties in the EV industry, with the company awaiting a major customer’s commitment.
Panasonic Holdings’ EV battery manufacturing unit has delayed the start of mass production of its new high-capacity battery model, citing a lack of confirmed orders from a major customer. This postponement highlights ongoing supply chain and demand uncertainties in the EV industry.
The delay involves Panasonic’s 4680 battery, a next-generation electric vehicle battery that is twice as large as its predecessor, the 2170 model, and has roughly five times the capacity. The company has indicated that it is awaiting a significant customer order before proceeding with mass production, which has yet to be confirmed.
According to sources familiar with the matter, Panasonic’s decision to delay is driven by the absence of a firm commitment from a key automaker or battery buyer. The postponement was announced publicly on May 12, 2026, and it marks a repeat of earlier delays that occurred as Panasonic struggled to secure sufficient demand for the new model.
Why It Matters
This development matters because Panasonic is a major supplier of EV batteries, and delays in production can impact the supply chain for electric vehicles globally. The postponement underscores persistent demand uncertainties in the EV market, which could influence automakers’ production schedules and the pace of EV adoption.

Background
Panasonic introduced its 4680 battery, a high-capacity model, as part of its strategy to compete with other leading battery manufacturers like CATL and LG. The company previously announced plans to ramp up production in 2025, but actual output has been delayed multiple times due to supply chain issues and fluctuating customer demand. The current delay reflects broader challenges faced by battery manufacturers in aligning production with automaker orders, amid a competitive and uncertain EV market environment.
“We are waiting for confirmed customer orders before proceeding with mass production of our new 4680 batteries.”
— a Panasonic spokesperson
“The delay indicates ongoing demand uncertainties in the EV supply chain, which could slow down the broader adoption of electric vehicles if supply remains constrained.”
