Solid-state / semi-solid Li-ion battery cells – a process-based categorization of divergent product development approaches

Divergent process technologies that are pursued by key commercial players towards launching next-generation solid-state or semi-solid Li-ion batteries are discussed and compared.

Some of these process technologies are fairly close to existing large-scale Li-ion battery electrode manufacturing processes. Newly emerging process technologies could solve protracted performance and longevity issues yet might in some cases involve elevated uncertainty with regards to up-scaling and the achievement of sufficiently low costs for EV applications.

This talk is based on an analysis of the global Li-ion battery patent literature using a unique ML framework.
