Vacuum‑deposited
metal anodes
FLUX produces ultra-thin metal anode materials by vacuum deposition (PVD): lithium metal, zinc, and LiF and Ag for anode-free batteries. Our lithium metal film is deposited directly onto copper foil at under 20 µm, replacing the ~80 µm graphite anode, with thickness uniformity within ±5% across widths over 250 mm.

Applications
Drones and robotics
More energy for the same weight extends flight time, payload capacity and operating hours.
Drones Multirotor · fixed-wing
- Longer flight timeMore energy without adding battery weight.
- Greater payload capacityLess battery mass, more available payload.
- Extended rangeLonger missions between charging stops.
Robotics Humanoid · mobile
- Longer operating timeMore working hours between charges.
- Improved mobilityLower battery weight reduces load on joints and actuators.
- More compact pack designHigher energy density in limited internal space.

Industry insights
A monthly summary of research, policy and company news in lithium metal and solid-state batteries.
All issuesThe US designates lithium metal a critical material
A $500M DOE programme routes money into domestic lithium metal supply, a PVD thin-film specialist takes $50M, and separators start doing work that used to belong to the anode.
Anode-free research adds a third stage: recovery
Forty-five institutions redefine the anode-free framework around reviving dead lithium, interface layers become bifunctional, and graphite dependency turns into a supply-chain strategy.
Dendrites turn out to be a mechanics problem
A Nature paper from Max Planck identifies hydrostatic stress, not electron leakage, as the root cause of dendrite penetration — and pack-level validation replaces cell-level claims.
