Penn State researchers developing methods to prolong operating life of valve regulated lead-acid batteries; electric locomotive as example

Green Car Congress

A team of Penn State researchers is developing more cost-effective ways to prolong the life of valve regulated lead-acid (VRLA) batteries, such as those applied in Norfolk Southern Railway No. They used electroimpedance spectroscopy and full charge/discharge to identify the main aging mechanisms. Earlier post.). —Shi et al.
