TL;DR
Panasonic’s unit responsible for EV batteries has delayed mass production again, awaiting a major customer order. The move highlights ongoing supply chain and demand uncertainties in the EV sector.
Panasonic Holdings’ electric vehicle battery division has delayed mass production of its new high-capacity 4680 battery model, citing the lack of a confirmed order from a major customer. The delay underscores ongoing supply chain and demand uncertainties in the EV industry.
According to sources familiar with the matter, Panasonic’s EV battery division has postponed its planned ramp-up of the 4680 battery, which is significantly larger and more capable than previous models. The delay is directly linked to the absence of a confirmed purchase order from a key client, which has yet to commit to the new battery technology.
Panasonic’s 4680 battery, which is twice as large as its 2170 predecessor and offers roughly five times the capacity, represents a critical component in the company’s push to expand its EV battery offerings. The postponement affects Panasonic’s production schedule and could impact supply commitments to automakers planning to incorporate the batteries into upcoming electric vehicle models.
Why It Matters
This delay is significant because Panasonic is a major supplier of EV batteries for several automakers, including Tesla. The postponement may contribute to broader supply chain disruptions in the EV sector and could slow the deployment of new electric vehicle models that rely on Panasonic’s batteries. It also highlights the fragility of the supply-demand balance in the rapidly evolving EV market.

Background
Panasonic announced the development of its 4680 battery in early 2026 as part of its strategy to compete with other battery manufacturers like CATL and LG Energy Solution. The company had initially planned to begin mass production in the first quarter of 2026, but the rollout has been repeatedly delayed. The current postponement follows a period of cautious demand projections from automakers amid fluctuating EV sales and ongoing supply chain constraints.
