TotalEnergies Lubrifiants Launches Battery Safety Plate for Immersion Cooling

· Lubricants & Chemicals

TotalEnergies Lubrifiants has unveiled the Coolant Keep Plate (CKP), a passive technology designed to improve the safety of immersion-cooled lithium-ion batteries, the company said. Direct immersion cooling is a promising option for lithium-ion batteries under heavy loads, particularly during ultra-fast charging, but it raises safety concerns around fluid management and thermal runaway. The CKP is positioned as a passive solution, meaning it operates without active controls or power. The launch extends TotalEnergies' lubricant and fluid expertise into battery thermal management, a fast-growing niche where fluid chemistry and safety intersect. For the lubricants industry, it signals continued diversification beyond traditional engine oils into EV-related fluids, a key growth area as electrification reshapes demand.

Why it matters：As electrification erodes traditional engine oil demand, battery thermal management fluids represent a strategic growth path for lubricant makers, and TotalEnergies' launch shows how incumbents are positioning for it.

Key points

  • Coolant Keep Plate is a passive technology for immersion-cooled lithium-ion batteries.
  • Direct immersion cooling is seen as promising for heavy loads and ultra-fast charging.
  • The product extends TotalEnergies' fluid expertise into battery thermal management.
