Battery Electrolyte

There are several types of electrolytes in battery industry.

Lisicon-like Li3PO4

LiGePS Type

Argyrodite

NASICON-like

Garnet

Perovskite

Composite Polymer Electrolyte (Link)

Liquid

A Film deposition example

The Li PS Cl solid electrolyte (99 wt%, 3 μm, Mitsui Mining & Smelting Co., Ltd) and a non-aqueous acrylate-type binder (1 wt%) in xylene (superdehydrated, FUJIFILM Wako Pure Chemical Corporation) and anhydrous isobutyl isobutyrate (Aldrich, 98%) (50:50 w/w) were mixed with 4 Å molecular sieves and ZrO2 beads (Nikkato, diameter of 3 mm) by using a planetary centrifugal mixer (Thinky Corporation, AR-100) at 2,000 r.p.m. for 6 min (six rotations per minute). The resulting mixture was coated on a release polyethylene terephthalate film (75 μm) using a doctor blade and then the film was dried on a hotplate at 50 °C for a few minutes and dried in a vacuum oven at 40 °C overnight. The thickness of the prepared SSE sheet was ~40 μm, which reduced further to 30 μm after pressurization in a cell. All the processes were carried out in a dry room (dew point below −50 °C).
