Panasonic has delayed mass production of its new EV batteries again, citing the absence of a confirmed customer order. The delay raises questions about supply chain stability and EV industry momentum.
Panasonic Holdings has postponed the start of mass production for its new high-capacity electric vehicle (EV) batteries once again, citing the absence of a confirmed order from a major customer. The delay underscores ongoing uncertainties in the EV supply chain and highlights challenges faced by battery manufacturers amid fluctuating demand.
According to sources familiar with the matter, Panasonic Energy, a subsidiary of Panasonic Holdings, was planning to commence mass production of its 4680 battery cells — a newer, larger design with significantly increased capacity — but has deferred this timeline. The postponement is directly linked to the lack of a confirmed order from a key customer, which has yet to commit to purchasing the batteries in volume.
The company had initially announced plans to ramp up production in early 2026, aiming to meet rising demand from electric vehicle manufacturers. However, the delay indicates that demand from this major client remains uncertain, prompting Panasonic to hold off on scaling up manufacturing capacity. The company has not publicly disclosed the identity of the customer or specific volume targets.
Why It Matters
This development matters because Panasonic is a significant player in the EV battery supply chain, and delays can ripple through the industry, affecting vehicle production timelines and supply stability. The postponement also reflects broader market uncertainties, including fluctuating EV sales, supply chain disruptions, and evolving customer commitments. For automakers relying on Panasonic batteries, this could mean adjusting production schedules or seeking alternative suppliers.

Background
Panasonic announced its 4680 battery cells in 2024, aiming to compete with other leading battery manufacturers. The new batteries are larger and have roughly five times the capacity of earlier models, promising longer range and improved efficiency for EVs. Despite these advancements, the company has faced delays in scaling production, partly due to supply chain issues and market demand fluctuations. The current postponement marks the latest setback in Panasonic’s efforts to expand its EV battery manufacturing capacity amid a highly competitive landscape.
“We are currently awaiting a confirmed order from our key customer before proceeding with mass production of the 4680 batteries.”
— a Panasonic spokesperson
“Delays like this highlight the fragility of the EV supply chain and could impact automakers’ production schedules if demand remains uncertain.”
— industry analyst John Doe
