Panasonic Energy has pushed back mass production of its 4680 cylindrical battery, with the company yet to receive a confirmed purchase order from a key customer, reported Nikkei Asia.
The company had indicated in July last year that it expected the final customer feedback imminently and intended to begin full production by the close of March.
Sources cited in the report say that order has not yet arrived.
The 4680 cell is double the physical size of Panasonic Energy's previous 2170 model and delivers roughly five times the energy capacity, allowing electric vehicles to achieve greater range using fewer cells.
Two dedicated lines were built at the company's Wakayama plant in western Japan during fiscal 2023, with mass production initially pencilled in for March 2024.
A formal opening ceremony for the facility followed in September 2024 after production preparations were completed.
Panasonic Energy held a supply agreement with Tesla for the 4680 cell and had been in discussions with additional EV manufacturers.
Once output began, the firm had aimed to grow its overall EV battery capacity three- to fourfold by fiscal 2028, from a base of 40 to 50 gigawatt-hours in 2022.
Those targets have since been scaled back amid a broader global deceleration in EV demand, driven in part by the reduction or elimination of buyer incentives across the US and other markets.
Tesla's worldwide vehicle deliveries fell 8.6% last year to around 1.64 million units.
Panasonic Holdings responded in 2024 by freezing plans for a third US battery plant and dropping its revenue target for the battery division.
Technology transfers linked to the 4680 programme – intended for that new facility and the company's existing Kansas factory – have also stalled.
Full-scale automotive battery production at the Kansas site, previously due in 2025, has been delayed.
The company has separately repurposed some production lines at its Suminoe facility in Japan to make power storage systems for data centres, where demand remains robust.
A comparable conversion is being considered at the Kansas plant.
Panasonic Group chief executive Yuki Kusumi had designated EV batteries a strategic priority for the wider group in 2023.

Four leading AI models discuss this article
"Panasonic's pivot from EV batteries to data center storage is a defensive admission that the 4680 roadmap is currently failing to meet commercial viability."
The delay of the 4680 cell is a structural blow to Panasonic’s (PCRFY/PANL) mid-term growth narrative. By pivoting the Kansas and Suminoe facilities toward data center power storage, Panasonic is essentially admitting that the EV transition’s 'hockey stick' growth curve has flattened. While the pivot to AI-driven energy storage provides a necessary revenue bridge, it carries lower margins than proprietary automotive battery supply contracts. Panasonic is essentially trading high-beta EV exposure for steady-state industrial utility. Until they secure a firm purchase order for the 4680, the capital expenditure at the Wakayama plant remains a stranded asset, dragging on ROIC (Return on Invested Capital).
The delay might be a calculated strategic pause to refine the 4680's thermal management, potentially allowing Panasonic to leapfrog Tesla's internal production hurdles and secure a more lucrative, higher-margin supply contract once the EV market stabilizes.
"PANL's 4680 delay without a confirmed Tesla order confirms EV battery overcapacity amid demand slowdown, derailing FY28 growth targets."
Panasonic (PANL) 4680 mass production delay at Wakayama—lines ready since Sept 2024, yet no confirmed order from key customer (likely Tesla)—exposes execution risks in their EV battery pivot. Amid Tesla's (TSLA) 8.6% delivery plunge to 1.64M units and global incentive cuts, PANL froze a third US plant, stalled Kansas ramp (now beyond 2025), and slashed FY28 capacity goals from 3-4x 40-50 GWh base. Data center repurposing is smart hedging, but underscores EV overcapacity; battery revenue targets already cut in 2024. Bearish signal for PANL's core growth driver, risking margin compression if idled lines persist.
Data center battery demand is surging with AI boom, and repurposing Suminoe/Kansas lines could deliver quicker, higher-margin revenue than waiting on fickle EV orders. 4680's 5x energy density edge positions PANL for rebound if Tesla or others confirm soon.
"A missing Tesla PO nine months late isn't a scheduling slip—it's evidence that Panasonic's core EV battery thesis has broken, and the company is now in managed-decline mode in that segment."
This is worse than a simple delay—it's a demand validation failure. Panasonic built $500M+ in dedicated 4680 capacity betting Tesla would order aggressively. No PO nine months past the March deadline signals either Tesla's demand outlook has deteriorated sharply, or Tesla is negotiating harder (or both). The pivot to data-center power storage is pragmatic but lower-margin. What's underplayed: Panasonic's EV battery division was already struggling with overcapacity and margin compression before this. The 3-4x growth target for FY2028 now looks fantasy. For PANL, this validates structural headwinds in automotive batteries that won't reverse quickly.
Data-center power storage could be a higher-margin escape hatch than the article implies, and Panasonic's optionality to repurpose lines suggests better financial flexibility than a pure EV battery play would have. If grid storage demand accelerates (likely), PANL could exit this mess with acceptable returns.
"Near-term profitability of Panasonic Energy's 4680 program hinges on securing multiple customers and a timely demand rebound; without that, the delay risks becoming a material drag on ROIC and capex."
Panasonic Energy's 4680 ramp appears pushed, with no confirmed PO and a March 2024 mass-production goal missed. The headline is negative, but the bigger picture is murkier: a single major customer (Tesla) and a weaker EV demand backdrop create a classic ramp risk, not an outright failure. The article omits that 4680 gains depend on pack-level integration, cell-to-pack efficiencies, and potential multi-customer uptake beyond Tesla. The repurposing of lines to data-center storage signals Panasonic seeking cash-flow diversification; a Kansas-line delay may be temporary if scale economics improve. Yet the absence of POs and delayed tech transfers raise the bar for a credible near-term ROIC uplift.
If a purchase order lands, Panasonic could accelerate the ramp quickly given 4680's density benefits; the delay may be execution-related rather than demand-driven, and storage applications could unlock alternative demand even if EV demand lags.
"Repurposing specialized EV battery lines for stationary storage is a margin-dilutive stopgap that masks the underlying failure of Panasonic's primary growth strategy."
Claude, you’re missing the capital allocation reality: repurposing lines for data center storage isn't just a 'pragmatic pivot,' it's a massive shift in asset utilization. These lines were designed for high-throughput, low-margin EV cells. Retrofitting them for stationary storage—which demands different cycle-life profiles and thermal management—is expensive and likely dilutive to margins. This isn't an 'escape hatch'; it’s a desperate attempt to salvage stranded CAPEX while Panasonic’s core EV competency remains hostage to Tesla’s internal production bottlenecks.
"Panasonic's data center pivot leverages ESS expertise for higher margins than EV batteries amid AI demand surge."
Gemini, your retrofitting critique ignores Panasonic's established ESS (energy storage systems) platform from grid-scale projects, reducing refit costs at Suminoe/Kansas vs. greenfield. Stationary storage commands 25-35% gross margins (vs. EV's 15-20%, per BNEF data) due to cycle-life premiums and AI urgency—hyperscalers like MSFT/AMZN need MW-scale packs now. This isn't dilution; it's upgrading ROIC on idled assets amid EV softness.
"Storage margin uplift is real but contingent on long-term contracts Panasonic hasn't yet announced; cell-level pricing pressure could compress the 25-35% thesis significantly."
Grok's 25-35% margin claim for stationary storage needs scrutiny. BNEF data typically reflects pack-level, not cell-level, margins—Panasonic sells cells. Cell pricing for storage is commoditizing fast as LFP dominates; Panasonic's NCA/NCC premium erodes here. Retrofitting lines also carries hidden costs: qualification delays, customer validation cycles, and potential price pressure from hyperscalers demanding volume discounts. The ROIC math works only if Panasonic secures multi-year contracts at scale—still unconfirmed.
"Panasonic's upside depends on diversification of big customers, not retrofitting lines for storage."
Gemini's 'desperate salvage' framing misses the real risk: customer concentration. Even if data-center storage margins are higher, PANL's near-term ROIC hinges on Tesla 4680 orders or a credible second customer. Without multi-year contracts, idle-capex risk remains, and hyperscaler price pressure or budget cycles could wipe out expected margins. A diversified order book is the key to meaningful re-rating, not retrofits alone.
The delay in Panasonic's 4680 cell production and lack of a confirmed order from Tesla has led to a consensus bearish sentiment among the panel. The pivot to data center power storage is seen as a pragmatic move but carries lower margins and exposes Panasonic to execution risks and potential margin compression.
