The core answer: Renault sources lithium-ion battery packs from multiple external suppliers, led by LG Energy Solution (LGES) and CATL, with the exact partner varying by model and market.
Battery suppliers: who provides Renault's cells
Renault has built a diversified supplier base to secure battery supply for its growing electric lineup. The alliance has partnered with major cell makers to assemble packs used across different models and regions, and contract arrangements can change as new agreements are reached.
- LG Energy Solution (LGES) — A leading supplier for several Renault electric vehicles, with packs used in models across recent years and ongoing projects in Europe.
- CATL — A key alternative partner for certain Renault Group vehicles in various markets, providing lithium-ion packs for selected models.
- Samsung SDI — Historically involved in some Renault-Nissan Alliance battery programs; its current role varies by model and contract.
The above reflects Renault's strategy of diversification to reduce supply risk and to support its European-scale EV production. The exact supplier for a given model is defined by production contracts and can evolve over time.
Implications for the Renault lineup
With multiple battery partners, Renault can tailor packs to different vehicle classes, optimize cost and performance, and adapt to shifting market conditions. This approach also supports broader goals around local production, recycling, and long-term energy strategy in Europe.
Battery chemistry and packaging (what the cells are like)
Renault's battery packs are built from modern lithium-ion cells, typically using nickel-manganese-cobalt (NMC) chemistries. Packs are designed as modular underfloor modules to maximize interior space and thermal management, while the choice of supplier influences the specific chemistry and performance characteristics.
Summary
Renault powers its electric vehicles with lithium-ion battery packs sourced from multiple external suppliers, chiefly LG Energy Solution and CATL. The supplier mix varies by model and market, reflecting a strategy to diversify supply, optimize cost, and support Renault's expanding electric lineup in Europe and beyond.
Who makes the battery for the Renault 5 E-Tech?
The Renault 5 E-Tech has two battery packs defined by usable energy of 40kWh and 52kWh. Initially the vehicle is launched with the 52kWh usable pack. This pack is assembled by Ampere, a subsidiary of Renault and using AESC pouch cells.
Are Renault batteries good?
Renault has over 10 years of experience with electric vehicle lithium-ion batteries. Durability exceeds industry projections, with very little capacity loss over 10 years.
Are Nissan and Renault the same?
The Renault–Nissan–Mitsubishi Alliance, originally known as the Renault–Nissan Alliance, is a French-Japanese strategic alliance between the automobile manufacturers Renault (based in Boulogne-Billancourt, Île-de-France, France), Nissan (based in Yokohama, Kanagawa, Japan) and Mitsubishi Motors (based in Minato, Tokyo, ...
What type of battery is in the Renault EV?
The lithium-ion battery is currently the benchmark technology for electric cars. Renault chose to equip its E‑Tech electric vehicles with this technology, as it offers customers an optimal technical solution with maximum benefits: high energy density giving long driving range.
