Traction comparative evaluation

Further details are given in the systems comparison under Comparative Evaluation of Traction Battery Separators , below. 

Comparative Evaluation of the Traction Battery Separators Which separator properties are important for use in traction batteries For this aspect primarily the highly predominant application, namely forklift traction batteries, is to be considered chemical resistance against attacks by acid and oxidation, mechanical stability for problem-free assembly, stiffness to counteract overexpansion of the negative active material, and low acid displacement are particularly desirable. Delay in antimony poisoning, absence or near-absence of oily deposits in the cells, and - last but not least - a low electrical resistance complete the requirement profile. 

Brantley and Day then conducted a study to compare the tire performance of emulsion- and solution-polymerized SBR [12]. The authors noted that solution-polymerized polymers, which tend to have a narrower molecular weight distribution and lower Tg than equivalent emulsion-polymerized polymers, have lower hysteretic properties. Tliey then showed that a solution SBR with the same bound styrene as an emulsion SBR will give lower rolling resistance, improved dry traction, and better tread wear. Emulsion SBR, however, tends to show better wet skid, wet traction, and wet handling performance. Kern and Futamura later elaborated on this work by evaluating the impact of...
