Xiaomin Zhang: One of the Brains Behind Thin Battery Separators and Membranes

Xiaomin Zhang is a seasoned inventor who has contributed significantly in the field of battery separators and membranes. Based in Charlotte, NC, Xiaomin has so far registered 29 patents in his name. His inventions include thin battery separators and membranes, microporous membranes, and shutdown membranes, among others.

His latest patents on thin battery separators offer optimized and novel membranes, separators, batteries, and systems that prevent dendrite growth, prevent internal shorts due to dendrite growth, or both. The invention also includes lithium primary batteries or packs incorporating such separators, and the systems incorporating such batteries.

Another invention by Xiaomin is a multilayer dry process polyethylene/polypropylene/polyethylene microporous separator. This separator is manufactured through machine direction stretching followed by transverse direction stretching and a subsequent calendering step. This process reduces the thickness of the multilayer microporous membrane, reduces the percent porosity of the multilayer microporous membrane in a controlled manner, and/or improves transverse direction tensile strength. The thin multilayer microporous membrane produced through this process is easily coated with polymeric-ceramic coatings, has excellent mechanical strength properties due to its polypropylene layer or layers, and has a thermal shutdown function due to its polyethylene layer or layers.

Xiaomin has worked with Celgard Inc. and BASF SE Corporation. Among his coworkers are Lie Shi and Kristoffer K Stokes.

In conclusion, Xiaomin Zhang's contribution to the innovation in the field of battery separators and membranes cannot be underestimated. His patented inventions have proven to be groundbreaking, improving the efficiency and safety of batteries and systems. We look forward to more inventions from him and other brilliant innovators in the field.
