An automatic replacement device of a secondary battery material including reel support parts to support a supply reel; a material support part spaced apart from the reel support part; clamping parts, each including a clamping roller to come into contact with the material when replacing the supply reel, a vacuum suction part to suction the material by vacuum, a clamping frame to rotatably support the clamping roller and the vacuum suction part, and a cutter to cut the material when coming into contact with the material; first drive parts to move the clamping roller toward/away from the material; and second drive parts to move the cutter toward/away from the material, wherein the automatic replacement device cuts the material as the material is suctioned to the vacuum suction part after being adhered to a material wound around a replacement supply reel when the supply reel is replaced.

Methods, systems, and compositions for the liquid-phase deposition (LPD) of thin films. The thin films can be coated onto the surface of porous components of electrochemical devices, such as battery electrodes. Embodiments of the present disclosure achieve a faster, safer, and more cost-effective means for forming uniform, conformal layers on non-planar microstructures than known methods. In one aspect, the methods and systems involve exposing the component to be coated to different liquid reagents in sequential processing steps, with optional intervening rinsing and drying steps. Processing may occur in a single reaction chamber or multiple reaction chambers.
