摘要： An improved method of forming a precipitated transition metal salt useful to make a lithium transition metal oxide useful for making a lithium ion battery comprises the following. A transition metal solution comprised of a dissolved transition metal salt in water and an alkali solution comprised of an alkali salt dissolved in water are introduced into a reactor having an inlet and an outlet connected by a tubular member having therein packing. The rate in which said solutions are introduced are such that the pH of the overall solution in the reactor has pH of 5 to 12 and the time of reaction (mere seconds to several minutes) in the reactor is sufficient to form a precipitated transition metal salt in an effluent liquid. The transition metal salt precipitate in the effluent is discharged from the reactor and the salt separated from the effluent, where it can be purified by washing and dried and subsequently heated with a lithium compound to form a lithium metal oxide useful for making lithium ion batteries.

摘要： A multilayer cast film includes a cling layer, a release layer, and at least one core layer disposed between and contacting the cling layer and the release layer. The cling layer includes an ultra low density polyethylene (ULDPE), a propylene interpolymer, or blends thereof. The release layer includes a first linear low density polyethylene (first LLDPE) having a density of from 0.915 to 0.938 g/cc and a melt index of from 0.5 g/10 min to 10 g/10 min. Each of the core layers includes a second linear low density polyethylene (second LLDPE) having a density of from 0.905 to 0.930 g/cc and a melt index of from 0.5 g/10 min to 10 g/10 min. The multilayer cast film includes from 3 wt% to 7 wt%, based on a total amount of polymers present in the multilayer cast film, of the low density polyethylene (LDPE).
