The American energy storage and electric vehicle firm, Tesla, has reportedly had delays in the manufacturing of its Model 3 car due to faulty or flawed parts.

The production of the company’s latest model, which has already received 400,000 reservations, was suspended at the end of last month.

Tesla announced in July 2017 that it would be making 20,000 of its Model 3 vehicles by December of the same year.

The target has now been lowered to 2,500 per week by the end of March and aiming to reach 5,000 by June.

According to CNBC, a Tesla employee has revealed that approximately 40% of the made or received parts in its Fremont factory are flawed and will need to be reworked.

Another employee working at the facility has claimed that the firm is struggling to meet production targets due to the amount of flawed parts.

Tesla is allegedly introducing engineers to the site to rework the parts, CNBC reported.

The firm has denied this, stating: “Our remanufacturing team does not 'rework' cars.”

“Even during what is considered 'launch' mode, if a company is selling its cars to customers, it should not be experiencing large amounts of rework,” commented Matt Girvan, lean manufacturing specialist and founder of MAG Consulting, CNBC noted.

“This speaks to an internal quality issue that is on a magnitude that is not normal for most car manufacturers,” he added.

Ultium Cells LLC and Li-Cycle join forces to expand recycling in North America, recycling up to 100% of the scrap materials in battery cell manufacturing

Ultium Cells LLC - a joint venture between General Motors and LG Energy Solutions - has announced its latest collaboration with Li-Cycle. Joining forces the two have set ambitions to expand recycling in North America, recycling up to 100% of the scrap materials in battery cell manufacturing

 

What is Ultium Cells LLC?

Announcing their partnership in December 2019, General Motors (GM) and LG Energy Solutions established Ultium Cells LLC with a mission to “ensure excellence of Battery Cell Manufacturing through implementation of best practices from each company to contribute [to the] expansion of a Zero Emission propulsion on a global scale.”

Who is Li-Cycle?

Founded in 2016, Li-Cycle leverages innovative solutions to address emerging and urgent challenges around the world.

As the use of Lithium-ion rechargeable batteries in automotive, industrial energy storage, and consumer electronic applications rises, Li-Cycle believes that “the world needs improved technology and supply chain innovations to better recycle these batteries, while also meeting the rapidly growing demand for critical and scarce battery-grade materials.”

Why are Ultium Cells LLC and Li-Cycle join forces?

By joining forces to expand the recycling of scrap materials in battery cell manufacturing in North America, the new recycling process will allow Ultium Cells LLC to recycle cobalt, nickel, lithium, graphite, copper, manganese and aluminum.

“95% of these materials can be used in the production of new batteries or for adjacent industries,” says GM, who explains that the new hydrometallurgical process emits 30% less greenhouse gases (GHGs) than traditional processes, minimising the environmental impact. Use of this process will begin later in the year (2021).

"Our combined efforts with Ultium Cells will be instrumental in redirecting battery manufacturing scrap from landfills and returning a substantial amount of valuable battery-grade materials back into the battery supply chain. This partnership is a critical step forward in advancing our proven lithium-ion resource recovery technology as a more sustainable alternative to mining, " said Ajay Kochhar, President, CEO and co-founder of Li-Cycle.

"GM's zero-waste initiative aims to divert more than 90% of its manufacturing waste from landfills and incineration globally by 2025. Now, we're going to work closely with Ultium Cells and Li-Cycle to help the industry get even better use out of the materials,” added Ken Morris, Vice President of Electric and Autonomous Vehicles, GM.

Since 2013, GM has recycled or reused 100% of the battery packs it has received from customers, with most current GM EVs repaired with refurbished packs.

"We strive to make more with less waste and energy expended. This is a crucial step in improving the sustainability of our components and manufacturing processes,” concluded Thomas Gallagher, Chief Operating Officer, Ultium Cells LLC.
