This doesn't look too promising. In a very rudimentary comparison of lead acid and 'solid state' batteries the problems listed against solid batteries (meaning Li ion unless I'm mistaken) are not problems at all but strengths, so no sign of bias there. One such strength was 'low occurrence of short circuits' for example. The section on VRFBs makes no comparitive assessment and appears to have been copy and pasted from wikipedia. Later ( p99) in a section on risks they state "Should Redox Flow Batteries be used on site, a Major Hazards Risk Assessment must be undertaken, where relevant to the specific battery technology used, prior to storage and operation on site, and the recommendations of the assessment be implemented." There is no mention of the risks associated with Li ion.
