Seven-Eleven Japan, Toyota launching next-gen convenience store project in 2019; fuel cell trucks and generators

Green Car Congress

Seven-Eleven and Toyota entered into a basic agreement in August 2017 regarding considerations toward energy conservation and carbon dioxide emission reduction in store distribution and operation. The in-store FC generator will generate electricity from hydrogen for store use.

University of Sydney team advances rechargeable zinc-air batteries with bimetallic oxide–graphene hybrid electrocatalyst

Green Car Congress

University of Sydney team advances rechargeable zinc-air batteries with bimetallic oxide–graphene hybrid electrocatalyst. Cheaper to produce than lithium-ion batteries, they can also store more energy (theoretically five times more than that of lithium-ion batteries), are much safer, and are more environmentally friendly. Resources.

Study: hydrogen boride nanosheets are a promising hydrogen carrier; 8wt% under ambient conditions

Green Car Congress

The two-dimensional materials derived from magnesium diboride (MgB 2 ) were first reported by researchers in Japan in 2017. Innovative nanosheets made from equal parts of hydrogen and boron have a greater capacity to store and release hydrogen compared with conventional metal-based materials.

Nano-vault architecture alleviates stress in Si-based anodes for Li-ion batteries

Green Car Congress

But in graphite anodes, six atoms of carbon are needed to store one lithium ion, so the energy density of these batteries is low. One of the most promising candidates to increase the number of lithium ions stored in the anode is silicon, which can bind four lithium ions for every one silicon atom.
