Panasonic Delays Mass Production of 4680 EV Battery Amid Customer Order Uncertainty

Bearish (-0.5)Impact: Medium

Published on May 11, 2026 (3 hours ago) · By Vibe Trader

Panasonic Holdings has once again postponed the mass production of its new 4680 electric vehicle battery due to a delay in receiving a major customer order [1]. The 4680 battery, produced by Panasonic Energy, is notable for being twice as large as the company's previous 2170 model and offering approximately five times the capacity [1]. This advanced battery was expected to strengthen Panasonic's position in the rapidly expanding electric vehicle market [1].

The latest postponement represents another setback for Panasonic's ambitions to grow its presence in the global EV battery sector [1]. The company had previously scheduled the start of mass production for the 4680 battery, but this timeline has now been pushed back, reflecting ongoing uncertainty in customer demand and industry timing [1].

Panasonic's delay occurs as competition in the EV battery market intensifies, particularly from Chinese manufacturers who are increasing their global market share [1]. The company's ability to scale up production of advanced batteries like the 4680 is considered crucial for maintaining competitiveness and meeting the evolving requirements of automakers [1].

As of now, Panasonic has not announced a new timeline for the start of mass production, stating that it is still awaiting confirmation of orders from its major customer [1].

CONCLUSION

Panasonic's repeated delay in launching mass production of its 4680 EV battery highlights ongoing challenges in securing customer commitments amid fierce industry competition. The lack of a new production timeline adds uncertainty to Panasonic's efforts to strengthen its position in the global EV battery market.
