A system and method for separating battery components provides for the separation of batteries into their individual layers of anodes, cathodes, first polymer separator layers, and second polymer separator layers. A battery casing of a battery is cut to uncover a battery cell core, which is then washed to remove an electrolyte therefrom. An outer wrapping layer of the washed battery cell core is cut to form an open loose end, and the open loose end is engaged by first and second rollers to unroll a laminate therefrom. The laminate includes a cathode layer, an anode layer, a first polymer separator layer, and a second polymer separator layer. The laminate is then separated into the cathode layer, the anode layer, the first polymer separator layer, and the second polymer separator layer with the first roller, the second roller, a third roller, and a fourth roller. Each layer is then collected.

System and method for separating battery components

Monodispersed metal nanoparticles are prepared by preparing a homogeneous metal complex solution by mixing metal salt with a complexing agent in solvent. A precipitating agent is added into the homogeneous metal complex solution to form a slurry. A homogeneous mixture of reducing agent and solvent is added to perform reducing reaction on the slurry to form metal nanoparticles in a controlled environment under gas purge. A capping agent is added to modify surface properties of metal nanoparticles. The metal nanoparticles are washed and the metal nanoparticles are recovered by phase extraction or centrifugation. The technique can be used to prepare conductive pastes with bimodal particle size distribution.

The system for separating battery cell cores includes a cell core holder for receiving and holding a battery cell core. A cutter cuts an outer wrapping layer of the battery cell core to form an open loose end. A first roller rotates the battery cell core and a sheet opener engages the open loose end to unroll a laminate, which includes a cathode layer, an anode layer, and a polymer separator layer sandwiched therebetween. A pair of second rollers receive, grip and selectively drive movement of the laminate. A cathode breaker applies breaking force to the cathode layer to produce broken cathode layer pieces, which are then collected. An anode breaker then grasps and vibrates the laminate to produce broken anode layer pieces, which are also collected. Finally, a polymer separator layer cutter selectively cuts the polymer separator layer to produce cut polymer separator layer pieces, which are collected.

System and method for separating battery cell cores

A method and apparatus for safely dissembling lithium ion batteries and separating components thereof is provided. The apparatus includes a container having a top portion and a bottom portion. The top portion includes a cutter system. A load-in fixture is located at a central portion of the cutter system between the first cutter and the second cutter. After the lithium ion battery is securely fastened and each end of the lithium ion battery is cut, a pushing rod/bar extending transversely through a central axis of the cutting system is pushed through the core of the lithium ion battery. The separated components of the lithium ion battery are deposited in a cell components collection system in a bottom portion of the container. The cell cores are collected in a cell cores collection box and the metal casing and casing ends are collected in a metal casing and casing ends collection box.
