Sekisui Chemical Co., Ltd. makes a wide variety of plastics, films, and active chemical components.  Whipping up something light and powerful in their kitchen must often be a matter of tossing available ingredients into a new recipe.  In this case, they’ve come up with something unique and potentially highly useful. Their research and development center director Satoshi Uenoyama announced “a high-capacity film-type lithium-ion battery “using a coating process that has simultaneously tripled its capacity (compared to other Sekisui Chemical products), increase its safety (as a result of standard safety testing, e.g. no problems with nail penetration tests or crush tests) and speeded up production by ten times (compared to other Sekisui Chemical products).” The company continues comparisons with its products, suggesting lithium-ion conductivity for the new battery is 10 times that of other Sekisui Chemical products.  They claim “enhanced safety” through the use of a high-performance gel-type electrolyte, which because of its high viscosity, can be spread onto the battery’s film materials as part of …
