What is a solid-state / semi-solid Li-ion battery technology decision tree?

Comprehension of solid-state / semi-solid Li-ion battery technology decision trees allows for the identification of promising product development directions that have not yet been explored.

Will CATL develop solid-state lithium batteries with lithium metal negative electrodes?

In January 2021, there were reports that CATL is developing solid-state lithium batteries with lithium metal negative electrodes, and that upon solving all technology / process issues, 400 Wh/kg energy density could be achieved.

Can a lithium ion battery be anode-free?

Although Li metal processing patents have been filed by CATL, employment of an ‘anode-free’ cell design is also a possibility. Positive electrode: NMC9½½ or NMC811 / conductive carbon / PVDF (96 : 2 : 2 by mass), see ‘Lithium-ion Battery High-energy Cathode Innovation & Patent Review’. Design: stacked multilayer, prismatic cells.

What is a solid-state electrolyte membrane?

Solid-state electrolyte membrane, solid-state battery and device (published in 2022): Solid electrolyte layer (20-30 μm): Li6PS5 / binder (80 : 20 by mass, binder type: probably SBR, screened with specific mesh number, 99 mass% of particles exhibit a particle size of 5-20 μm).

Are CATL & CALB suing each other for Li-ion battery intellectual property?

In December 2022, it was reported that companies CATL and CALB have filed lawsuits with respect to each other related to Li-ion battery intellectual property (not related to solid-state batteries).

Which electrolytes are suitable for lithium ion toxicity?

Unique capability: supramolecular ionic liquid / polymer / lithium salt electrolytes with very favorable ion conductivity (up to 2.4 × 10 -3 S/cm) and high boiling point (>438 °C), along with corresponding cells with lithium metal negative electrodes. Leap of faith: the toxicity of triphenylene-containing electrolytes will be acceptable.
