LMFP Batteries: What Manganese Adds to LFP

Lithium manganese iron phosphate — LMFP — is lithium iron phosphate with manganese swapped in for some of the iron. That one substitution raises the cell’s working voltage from about 3.2 volts to roughly 3.7, and with it the energy density: manufacturers quote...

ProLogium Starts Solid-State Battery Mass Production

ProLogium says it has begun mass-producing an all-solid-state battery cell that stores 381 watt-hours per kilogram — denser than any lithium-ion cell sitting in a car today, and the first solid-state cell the company has put on a production line at that figure. It is...

Why Electric Boats Are Harder Than Electric Cars

An electric boat is a much harder problem than an electric car, and the reason people reach for first — batteries do not hold enough energy — is the least of it. A battery pack carries roughly a twentieth of the usable energy of the same weight of diesel. That wall is...
