Technologies & chemicals

The world of storage batteries is undergoing rapid technological change. Understanding the different chemistries (LiFePO4, NMC, NCA), their advantages/disadvantages, and emerging technologies (V2G, V2H) allows you to make informed choices and anticipate future developments in your system.

This sub-category explores all battery technologies in depth: from lithium-ion chemistries to innovations such as V2G (Vehicle-to-Grid), which transforms your electric vehicle into a giant domestic battery.

LiFePO4 vs NMC vs NCA: which chemistry should you choose? LiFePO4 (Lithium Iron Phosphate) batteries dominate stationary home storage: maximum safety (no thermal runaway), exceptional lifespan (6,000-10,000 cycles), but lower energy density. NMC (Nickel Manganese Cobalt) batteries offer better density, but limited cycling (3,000-5,000) and high cost. NCA (Nickel Cobalt Aluminium) batteries are mainly used in electric vehicles (Tesla).

V2G/V2H/V2L: your EV as a domestic battery. Bidirectional technologies are revolutionising storage: V2G (Vehicle-to-Grid) allows energy to be fed back into the grid from the EV battery, V2H (Vehicle-to-Home) powers your home, and V2L (Vehicle-to-Load) provides 230V mobile electricity. Discover brand compatibility (Nissan Leaf, Hyundai Ioniq 5, Ford F-150 Lightning), compatible inverters, and regulations by country.

Also explore emerging technologies: sodium-ion batteries, redox flow batteries, gravity storage, and their prospects for industrialisation. The future of storage is taking shape now.
