Mini Recharged is converting classic Minis to EVs with "bespoke upcycling" program

Green Car Reports

Mini is launching an EV conversion program for classic cars. The Mini Recharged program will convert classic Minis to electric drive, with all changes reversible to protect the originality of donor cars, Mini said in a press release. The original engines are marked and stored, leaving the option for them to be refitted later.

U Waterloo team shows four-electron conversion for Li-O2 batteries for high energy density; inorganic molten salt electrolyte, high temperature

Green Car Congress

The new work, published in Science , shows that four-electron conversion for lithium-oxygen electrochemistry is highly reversible. The Waterloo team is the first to achieve four-electron conversion, which doubles the electron storage of lithium-oxygen, also known as lithium-air, batteries. —Xia et al. —Linda Nazar.

KIT/IIT team demonstrates suitability of high-entropy oxides (HEO) as conversion materials for reversible energy storage

Green Car Congress

Novel materials can considerably improve storage capacity and cycling stability of rechargeable batteries. Bottom: Schematics of the proposed de-/lithiation mechanism during the conversion reaction of TM-HEO. With HEO, electrochemical properties can be tailored, as was found by scientists at Karlsruhe Institute of Technology (KIT).

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.
