Ternary polymer lithium battery refers to a lithium battery whose positive electrode material uses a ternary positive electrode material of lithium nickel cobalt manganese or lithium nickel cobalt aluminate. There are many kinds of positive electrode materials for lithium ion batteries, mainly lithium cobalt oxide, lithium manganate, Lithium nickelate, ternary materials, lithium iron phosphate, etc. At present, the lithium battery of ternary material has replaced the lithium cobalt oxide battery that was widely used before, and is widely used in the field of notebook batteries.

Epson launches A4 size e-paper
Epson announced the successful development of 13.4 inches (diagonal length) of electronic paper with a resolution of 3104 × 4128 and an accuracy of 400dpi, which is the highest resolution electronic paper in the world. This new product uses E_Ink's electronic ink technology, and the peripheral drive circuit made with Epson's low temperature polysilicon thin film transistor (LTPS-TFT) facilitates the formation of a simple structure with narrow sides (including the driver circuit), based on the glass substrate, contrast 10 : 1, the reflectivity is 40%.
