$15 BILLION US GIGAFACTORY PUSH ACCELERATES NORTH AMERICAN CAPACITY GROWTH

The recent surge in investment in US gigafactories with the announcement by Panasonic, Honda and LG Energy Solution, as well as Toyota, could result in an additional 157 gigawatt-hours of annual production capacity by mid-decade, a 60% increase from current levels.

 

This is great news for the North American battery market, which is seeing rapid growth thanks to the increasing demand for electric vehicles.

In light of the new Inflation Reduction Act, the automotive industry must consider a shift in battery composition.

 

BofA Global Research reports that, in order to meet the act's requirements on sourcing critical materials, lithium iron phosphate batteries may become more prevalent.

Volvo Group’s Renault Trucks has announced the creation of its Used Parts Factory, a facility focused on recycling trucks and reusing the parts and raw materials. This new plant forms part of Renault Trucks' steps towards transitioning its operations to a circular economy approach.

The Used Parts Factory will handle used vehicles with high mileage, and parts with potential for re-use. End-of-life trucks will be dismantled at the factory, where components identified for re-use will be removed, including engine, gearbox, cabin, fuel tank, bumpers, and deflectors.

Freyr Battery SA and Nidec Corp, the world’s largest manufacturer of high-efficiency electric motors, signed a binding deal for lithium-ion batteries from Freyr’s arctic giga-factory.

The volume totals 38 gigawatt-hours and equates to projected revenues of more than US$3 billion (RM13.44 billion) for Freyr, the Norwegian company said in a statement on Tuesday.

 

The companies are converting and expanding a previously announced 31 gigawatt-hour conditional off-take agreement to a binding sales agreement running from 2025 to 2030

Improved Lithium Performance.webp

The research team at KERI has developed a high-capacity Li-metal battery with improved rate performance and stability using a one-dimensional Li-confinable porous hollow carbon host. A paper is published as a cover paper in ACS Nano.

 

Li-metal batteries have the potential to be 10 times more efficient than current Li-ion batteries, but they have been held back by dendrite growth and volume change caused by the use of metallic Li as anode.

 

The KERI team has developed a 1D Li-confinable porous carbon structure with a hollow core that mitigates these issues. Gold nanoparticles are added to the hollow core to control the growth direction of Li, and nano-sized pores are formed in the shell part to improve the Li-ion movement. This development could lead to safer, more efficient Li-metal batteries.
