Lithium-Sulfer Batteries on the Horizon, Promise 5 Times More Energy

Scientists from the Chalmers University of Technology in Sweden discovered a technique to bring Lithium-Sulfer batteries to the forefront of innovation. These batteries promise 5 times more energy for smartphones and computer devices as compared to conventional lithium-ion batteries. These next-generation batteries embed a graphene sponge, which acts like a freestanding electrode in the battery cell. It enables higher and better utilization of sulphur. The combination can deliver 1000-to-1500 watt-hours per

MIT researchers have invented a new fully flexible device which converts Wi-Fi signals’ energy into electricity. This new invention promises to power electronics such as smartphones, wearables, and laptops without batteries. “Rectennas” are the devices which can convert electromagnetic AC waves into DC electricity. However, this time researchers have invented new type of rectenna which utilizes a flexible radio-frequency antenna for capturing electromagnetic waves. Moreover, this rectenna also considers Wi-Fi

Schematic design and voltage as a functioning of the existing FlexTEG module help to operate at different temperature gradients. A research team from Osaka University developed a flexible thermoelectric generator (FlexTEG) module which is comparatively inexpensive. Thus, the TE module is applicable for large-scale usage. This module offers high mechanical reliability for highly efficient power generation. The Advanced Materials Technologies journal released the results of the research and module. Continuous
