CAS Dalian Institute of Chemical Physics develops rechargeable aqueous planar Zn//MnO2 micro-batteries fabricated by screen printing technology

The group of WU Zhongshuai from DICP has used a thixotropic ink based on manganese dioxide, zinc powder and graphene as active materials, to produce the positive, negative electrodes and the current collector of Zn//MnO2 batteries, respectively. In a multi-step screen printing process, a simple and low-cost preparation of planar Zn//MnO2 micro-batteries was achieved. The Zn//MnO2 batteries showed exceptional durability, with a capacity of 83.9% for 1300 cycles at current density of 5 C, good mechanical flexibility and uniform performance.

Alipay offers software to help sort garbage

The Chinese government has set a goal of 35 percent for household garbage recycling by 2020, and Shanghai has put into effect compulsory regulations from July 1, 2019. 45 other cities are about to follow soon. In response to this move, Alipay offers the beta phase of a “Garbage classification guide” that has indexed over 4,000 different types of waste such as  shrimp shells, facial masks, sunflower seed shells, medical cotton swabs etc. The customer takes a photo of a particular garbage or describes the garbage by voice; the software then applies either voice recognition or augmented reality (AR) scanning and image recognition, and provides suggestions by voice or text. Reportedly, over 3 million people have already tried out the new function by scanning waste items with their smartphones, which answers within seconds in which type of  litter bin a waste item belongs.  Xinhua news release, July 16, 2019
