ProLogium: In a few days we will show the ready-made solid electrolyte batteries [CES 2020]

Taiwanese company ProLogium says it has solid electrolyte cells and will be shipping them in a few days as ready-made packages suitable for automotive applications. The company also works with Nio, Aiways and Enovate. Could Chinese cars be the world's first vehicles to hit the road with solid-state batteries?

modern lithium ion batteries - also described as LIB, lithium-ion batteries - use electrolytes in the form of a liquid located between the cells or bound in a polymer layer impregnated with them, like a sponge. ProLogium Promises Breakthrough Shows Ready Solid State Batteries LCB, lithium ceramic (lithium ceramic batteries).

At CES 2020 (January 7-10), the company wants to present a new product: packages for cars, buses and two-wheeled vehicles, built on the basis of these solid elements. W rechargeable battery MAB The technology is "Multi Axis BiPolar +" (Multi Axis BiPolar +), which means that links are located in them, like sheets in a pack, one on top of the other – and were connected by electrodes.

Due to their small thickness compared to lithium cells, this is possible:

Solid State Cells = Smaller, Larger and Safer Batteries

The above arrangement eliminates wires and creates a package that is 29-56,5% denser in terms of energy than could be created in the same volume from Li-Ion cells (= with liquid electrolyte) with the same energy. density. ProLogium claims that 0,833 kWh/l has been achieved at the cell level – which in the world of classic lithium-ion cells is today only the promise of electrification:

> IBM has created new lithium-ion cells without cobalt and nickel. Loading up to 80% in 5 minutes more than 0,8 kWh / l!

What about cooling? The solid electrolyte conducts heat much better, so it is expected to be easier to remove, however, heat transfer layers are used between the sets of cells. At the same time, the manufacturer promises that LCB cells can be charged up to 5C. (5 times the battery capacity, i.e. 500 kW for a 100 kWh battery), and the anodes used in them can contain 5 to 100 percent silicon instead of graphite (source).

And they will give voltage on the electrodes even after the lumbago (voltmeter on the left, before the lumbago was 4,17 volts):

And this is where InsideEV's interesting speculation begins, which recalls that ProLogium cells have been tested by European, Japanese and Chinese manufacturers since 2016, but cannot be disclosed due to NDA (privacy agreement, source).

> Lotos will charge fees at Blue Trail charging stations. One fixed amount PLN 20-30?

Well, the portal indicates that the first machine that can use solid electrolyte cells will be Chinese. Enovate ME7... Both companies announced a collaboration at Auto Shanghai 2019 (source), and the Enovate ME7 will be the first Enovate model to be released.

However, in fairness, it should be added that ProLogium has established similar partnerships with Nio (August 2019) and Aiways (September 2019).
