Battery thin film production equipment

What is a thin film battery?

In particular, the market for thin film batteries is being driven by demand for technologies based on the internet of things (IoT), wearables, and portable electronics. The layers that comprise the anode, cathode, and electrolyte in thin film batteries are true to their name, with thicknesses on the order of microns (0.001 mm).

How do thin-film batteries work?

As with older batteries, materials lose or accept electrons, allowing the flow of electrical energy when the battery discharges or takes on a charge. Barrier layers in thin-film batteries control the movement of electrons and prevent the battery from short-circuiting.

How are thin film batteries deposited?

The layers that comprise the anode, cathode, and electrolyte in thin film batteries are true to their name, with thicknesses on the order of microns (0.001 mm). They are often deposited using physical vapor deposition, typically by thermal evaporation and sputtering.

What is lithium battery separator film?

Lithium battery separator film is the key component of the structure of lithium batteries. The film is made of plastic, which prevents direct contact between the anode and cathode to avoid the short circuit.

What is a solid-state thin-film battery?

A solid-state thin-film battery can be safer, smaller, and less expensive. However, the batteries depend on films that can be less than a micron thick, made of highly purified materials, making them dependent on innovative technologies based on PVD. The manufacture of thin-film batteries depends on scarce materials such as lithium.

Why are PVD cathodes used in lithium battery thin-film models?

The purity of PVD cathodes gives lithium battery thin-film models excellent electrochemical performance for high-power applications. A physical separation interface (an electrical insulator) prevents the anode and cathode from touching and short-circuiting the battery.
