Nissan aiming for $65/kWh solid-state lithium-ion battery pack and cobalt free cells by 2028

Thu, 12/16/2021 - 13:26 -- Paul Crompton

Vehicle OEM Nissan is targeting a $75/kWh cobalt-free and solid-state lithium-ion battery for its electric vehicles by the close of the decade.

Nissan aims to develop its lithium-ion battery technologies and introduce cobalt-free technology to reach the figure by fiscal year 2028.

Nissan believes solid-state battery packs could be as cheap as $75/kWh by 2028, and aims to bring the cost down to $65/kWh in a bid to achieve cost parity between EV and gasoline vehicles.

These are high ambitions, as a BNEF report this month noted that real term lithium-ion battery pack prices had reached $132/kWh this year— but rising raw material prices could mean the mythologised $100/kWh price may not materialise until 2026.

Japanese firm Nissan plans to launch an EV fitted with its proprietary all-solid-state batteries and is preparing a pilot plant in Yokohama, Japan as early as 2024. 

Some of the price goal will depend on Nissan’s economy-of-scale, with the vehicle maker working with its partners to increase its global battery production capacity to 52GWh by 2026, and 130GWh four years later.

Nissan also intends to expand its battery refurbishing facilities beyond Japan with new locations in Europe next year, and in the US in 2025 to support its circular economy in energy management.

Global patent activity shows growing interest in solid-state lithium-ion batteries

Mon, 11/29/2021 - 14:20 -- Paul Crompton

Japan is leading the world in solid-state lithium-ion battery development, at least according to the latest figures regarding patent filing from intellectual property firm Appleyard Lees.

Data-to-date research shows Japan filed the highest number of new patents in 2020, followed by China, the US and South Korea. 

European countries are lagging behind, with Germany having the highest number of filings but still underperforming when compared to the leading market players, according to Appleyards. 

The full dataset for 2020 is not yet available, however data from two years ago showed solid-state battery patent applications have grown exponentially since 2013, peaking at around 600 new applications in 2019.

The claims were made in Appleyard’s ‘Inside Green Innovation: Progress Report 2021’.

The report stated: “It’s important to note that although the number of yearly, new filings for solid-state batteries is still significantly lower than those for lithium-ion batteries, the former should soon surpass the latter. 

“Arguably, this may have already happened in jurisdictions outside China. This reflects its potential as a key innovation, particularly for EV markets.” 

Assignees of applications for solid state batteries include car manufacturers such as Toyota, Honda and Hyundai, which have filed new patent applications in recent years. 

Companies such as Japanese electronics manufacturers Murata MFG Japan, TDK and battery maker FDK are also filing solid-state applications. 

The most rapid growth in recent years has come from Chinese automotive supplier and battery cell manufacturer Svolt Energy Tech, which established its European production site in Germany in 2019. 

Overall, Svolt has filed over 550 patents worldwide, indicating its ambition to be a key player in the EV market. 

Lithium-ion battery applications

The report noted the recent top patent filers for lithium-ion batteries within China are major players in the automobile industry, with Hefei Guoxuan, Ningde Amperex Technology Ltd. and BYD subsidiaries manufacturing battery products suitable for vehicles and their electronic management systems.

Outside China, German engineering and technology firm Robert Bosch is a key assignee for lithium-ion technologies, consistently filing among the largest numbers of priority filings each year in the past ten years, according to the report.

As in China, car manufacturers are notable applicants, and include: General Motors (US), Toyota (Japan) and BMW (Germany). 

The report noted: “Even among the largest assignees, filing numbers have remained relatively low in recent years. It’s unclear whether the notable dip from 2020 onwards is due to an incomplete dataset or if R&D has been affected by supply chain and manufacturing issues.”

Lithium-ion battery recycler secures Japanese patent

Wed, 09/15/2021 - 15:22 -- Paul Crompton

Critical minerals company American Manganese (AMY) has secured a Japanese patent for its closed-loop lithium-ion battery recycling process.

The company’s RecycLiCo process was issued Patent No. 6906060 by the Japanese Patent Office.

The Japanese patent joins already issued patents in the US and South Korea (Patent No. 10-2246670). The Company has also filed National Phase Patent Applications for China, Europe, Australia, India, and Canada.

The patent provides coverage for AMY’s closed-loop method for achieving up to 100% extraction of cobalt, nickel, manganese, aluminium, and lithium from the treatment of cathode chemistries such as lithium-cobalt oxide (LCO), lithium-nickel-manganese-cobalt oxide (NMC), and lithium-nickel-cobalt-aluminium oxide (NCA). 

Compared to traditional hydrometallurgical recycling processes, the company says its process offers advantages such as faster reaction rates, lower consumption of acids, improved water balance, and higher leaching efficiency.

Larry Reaugh, president and CEO of American Manganese, said: “As we move towards our goal of commercialisation, we are reminded by the foundation of patents that supported our growth in battery recycling and we are honoured to be issued another patent by a country that is one of the world leaders in battery innovation.

“Innovation is at the core of our company and as a pioneer in battery recycling we continue to monitor new lithium-ion battery technologies and opportunities.”

Panasonic sells stake in long-term partner Tesla for $3.6 billion

Panasonic cells and Tesla car

Tesla’s lithium-ion battery maker Panasonic has sold its entire stake in the US electric vehicle OEM for almost $3.6 billion, reports Japanese business news outlet Nikkei.

Panasonic has said the sale will pay for its $7 billion acquisition of artificial intelligence software developer Blue Yonder, reported Nikkei.

Panasonic bought 1.4 million Tesla shares for about $30 million in 2010. Those stocks rose to $730 million at the end of March 2020, and by 24 June closed at $679.82 apiece.

Japanese firm Panasonic has been a long-term supplier of batteries to Tesla.

Last year, the pair signed a three-year pricing deal relating to the manufacture and supply of 2170 lithium-ion battery cells manufactured at its gigafactory in Nevada, US.

Panasonic said it would increase the energy density of its 2170 cells by 20% within five years and commercialise a cobalt-free version within three years.

The stock sell-off came in the same week China battery maker CATL extended a battery supply deal with Tesla to 2025.

Tesla entered into a partnership with South Korea’s LG Chem and China’s CATL in January 2020 as it looked to secure a lithium-ion battery supply for its electric cars at its Gigafactory 3 plant in Shanghai.

CATL signed a two-year battery supply agreement with Tesla, with the US firm determining the battery purchase volume, last July.
