PATHION develops new LiRAP-based solid-state electrolytes for Li-sulfur and sodium-ion batteries

Green Car Congress

At the Spring 2015 Materials Research Conference in San Francisco earlier this month, PATHION presented two new derivative superionic solid-state electrolytes built upon LiRAP (Lithium-Rich Anti-Perovskite). PATHION is working on a derivative for Li-sulfur batteries as well as a derivative that could be applied in a sodium-ion battery.

A closer look at graphite—its forms, functions and future in EV batteries

Charged EVs

Its physical structure allows it to store lithium ions. There are three main forms of graphite: spherical graphite is used in non-EV battery applications, whereas EV batteries use a blend of coated spherical graphite and synthetic graphite. Battery makers use a blend of CSG and synthetic graphite to form Li-ion battery anodes.

Update on JCESR’s progress toward 5-5-5 battery for EV and grid applications; convergent and divergent research strategies

Green Car Congress

In 2012, the US Department of Energy (DOE) awarded $120 million over five years to establish a new Batteries and Energy Storage Hub known as the Joint Center for Energy Storage Research (JCESR). The goal is a battery five times more powerful and five times cheaper within 5 years. Earlier post.) Crabtree (2015) Click to enlarge.
