Fewer than 40% of eligible models met escalating domestic-content thresholds in 2024, down sharply from 2023. Any curtailment would immediately flow through lease pricing, cooling demand in a price-sensitive segment. Automakers must either absorb the gap or delay launches, injecting cyclical volatility into the United States hybrid electric vehicle battery market.

Segment Analysis

By Battery Chemistry: Lithium-Ion Maintains Lead Amid Chemistry Diversification

The United States hybrid electric vehicle battery market size for lithium-ion solutions equaled 85.9% of the 2024 value, reflecting superior energy density and a maturing cost curve. Nickel-manganese-cobalt variants dominate plug-in architectures that need 220-260 Wh/kg, while lithium iron phosphate appeals to mild hybrids prioritizing safety and cobalt-free sourcing. Nickel-metal hydride’s role contracts as OEMs transition to higher-capacity lithium-ion designs, yet it survives in selected Toyota platforms because of proven durability. Lead-acid continues in 12-volt auxiliaries, but limited depth-of-discharge restricts its traction potential.

Emerging chemistries increase the addressable base of the United States hybrid electric vehicle battery market. Solid-state prototypes from Solid Power reached 390 Wh/kg in 2024 laboratory trials and target pilot output by 2026.
