New solid polymer electrolyte doubles proton flow rate

Engineers from the University of Pennsylvania and the University of Florida have recently made a breakthrough in the development of solid polymer electrolytes (SPEs). Current liquid electrolytes require thick, heavy housings in order to prevent leaks and fires from punctures, increasing their bulk and weight. SPEs solve many of these problems, but until recently, they were… Read more »

The agreement calls for an expansion of Super B’s operations, including solutions for transportation and renewable energy needs, and a ramping-up of Lithium Werks’ nanophosphate cell… Read more »

Siemens and Northvolt join forces to boost battery production

Northvolt plans to build a new Li-ion battery factory with an annual capacity of 32 GWh, aided by a €10-million investment from Siemens. This partnership will make Northvolt the main Li-ion battery supplier for Siemens and promote the use of new technologies and production methods. The new plant is meant to be an analog to… Read more »

Tesla’s “responsible sourcing” policy for cobalt and other exotics

How do you solve a problem like cobalt? The blue metallic element is used in significant quantities in EV batteries, but half the world’s supply of comes from the Democratic Republic of Congo, a war-torn land in which child labor is common. Several automakers are already taking steps to reduce their use of the costly… Read more »
