China deploys world’s first sodium-ion grid-scale battery ESS

The world’s first grid–scale energy storage system has been deployed in China, according to domestic news outlets.

The system was officially put into operation in Taiyuan, Shanxi Province, and is combined with municipal power, solar and charging facilities to form a micro-grid, reported English language newspaper The Global Times.

The system’s major developer was the Institute of Physics, Chinese Academy of Sciences, which has worked on the technology for 10 years.

The institute first demonstrated a 100kWh sodium-ion battery in 2019.

China has proposed a target of carbon neutrality by 2060, and is expected to widely use sodium-ion in a variety of sectors including: electric vehicles, home or industrial energy storage, 5G communication base stations and renewable energy.

Last month, UK battery maker Faradion announced that lithium-ion battery giant Contemporary Amperex Technology (CATL) would begin making sodium-ion batteries from July.

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.

Materials firm plans lithium-ion battery material plant in US

Thu, 07/01/2021 - 11:59 -- paul Crompton
Specialty materials firm Unifrax plans today to build its first large-scale SiFAB

Specialty materials firm Unifrax plans today to build its first large-scale SiFAB (silicon fiber anode material) manufacturing line in the US.

The New York-headquartered manufacturer plans to build the facility in the state of Indiana by the end of 2023.

It is the first time Unifrax has taken a step into developing silicon fiber for the lithium-ion battery manufacturing market. 

SiFAB is being tested in multiple battery systems, with Unifrax expecting results to show the material delivers faster charges and longer battery life for applications including electric vehicles, and energy grid storage.

The Indiana plant will be the first to begin building SiFAB long-term manufacturing capacity. 

John Dandolph, Unifrax president and CEO, said the ability to leverage their existing facility and add new infrastructure to support manufacturing would “significantly accelerate” the timeline for supplying to material to its partners.

Chad Cannan, senior vice president R&D, said: “We designed SiFAB from its inception to be manufactured at large scale so that we could supply all market segments (EV’s, consumer electronics, power tools, and renewable storage), utilise our existing global manufacturing footprint, and deliver a product that has a high degree of quality and consistency.”

Firm announces silicon boosted lithium-ion battery reaches 1,000mAh/g

Thu, 07/01/2021 - 11:16 -- paul Crompton

OneD Battery Sciences has unveiled an electric vehicle battery that uses silicon nanowires to boost the energy density of lithium-ion cells.

The announcement follows three years of testing on commercial EV-grade graphite used in the anodes of EV batteries by unnamed graphite suppliers, cell manufactures, and EV makers in the US, Europe, and Asia.

During testing, the firm provided customers with standard versions of the Sinanode anodes for laboratory testing. 

OneD says customers plan to further customise the process to meet their specific needs, including processing large enough quantities to build EV cells for optimization and qualification. 

Testing was conducted in pilot Sinanode facilities, which included the equipment needed to process the graphite powders provided by the OEM.

The June 10 announcement marked the commercial launch of the firm’s pilot line production program dedicated to electric vehicle OEMs. 

The first two facilities are in the US, and additional facilities are under negotiation.

Each facility is set up to process up to 800kg of anode active material per month, and enough anode active material for 34MWh.

Sinanode Pilot processing will begin around the end of the year and the firm anticipates its first anchor tenant to start production by the end of this year or early 2022. Until then, it is processing in its Palo Alto pilot facility.

OneD’s chief commercial officer Fabrice Hudry told BEST: “The Sinanode process is two parts: a Catalyst step and Silicon step. 

“The Catalyst step deposits nanoparticles of copper oxide onto the graphite particles. The Silicon step uses CVD ovens to grow silicon nanowires onto the graphite particles. 

“Each facility has a small production team dedicated full time to the OEM’s processing. The OEM can process multiple graphite powders and select various silicon percentages; they can also work with the OneD R&D team to access many inventions related to adopting the anode materials in specific electrode manufacturing processes and cell designs.

“We expect OEMs to fine-tune EV cells for both the high end and the low end of their EV models due in 2025. These models will enter production by 2024 and we will have the large scale processing ready by then to process according to their fully qualified specific Sinanode formulation.

Existing manufacturing processes

The company’s CEO, Vincent Pluvinage, told BEST: “Over the last ten years, we have built and tested thousands of full pouch cells built with various graphite substrates and various commercial cathodes. 

“We have also tested cells built by our customers from 18650 format to 60 Ah pouch formats. 

“We are currently negotiating the contracts for the programs.”

The firm’s Sinanode technology integrates into existing manufacturing processes to fuse silicon nanowires onto commercial graphite powders.

The higher energy density increases battery range while nanowires shorten charging time, which will enable OEMs to design and produce electric vehicles that answer market demands, say the firm.

The company says its Sinanode pushes the anode specific capacity to around 1,000mAh/g.

A graphite anode, which is widely used in commercial lithium-ion batteries, has a theoretical specific capacity of 372mAh/g.

The Sinanode anode material can be blended with graphite, to achieve initial coulombic efficiency of around 92%, and more than 1,000 full charge cycles than commercially available EV cells.

This reduces the investments and time necessary to scale up the Sinanode step to EV quantities, while decreasing the cost of EV anodes (measured in $ per kWh) by almost 50%, when compared to the cost of most competitive anodes used in EV batteries today.

Pluvinage said: “During this decade, we will witness the largest and fastest transformation of a global industry that’s ever been seen, and the decisions made today will determine which car makers come out on top.

 

“EV demand will be driven by range, charge time, and cost, and our technology addresses each of these purchase drivers in a significant way.”

Solid-state lithium-ion company to go public after merger with blank cheque firm

The battery industry’s gradual transition to solid-state lithium-ion technology continues this week with Solid Power signing a deal to become a publicly listed company.

The producer of all-solid-state batteries is due to trade on NASDAQ following a merger with Decarbonization Plus Acquisition Corporation III (DRC), a blank cheque firm sponsored by an affiliate of energy-focused private investment firm Riverstone Holdings.

Upon closing of the transaction, the combined company’s common stock and warrants are expected to trade under the ticker symbol “SLDP”, and is expected to have a nine-person board composed of a majority of independent directors and will continue to be led by its existing management team.

Cash proceeds to Solid Power will be used to fund operations and support its growth.

The boards of directors of both Solid Power and DCRC have approved the proposed transaction, which is due to be completed in the fourth quarter of 2021. 

Robert Tichio, chairman of the board of DCRC and partner at Riverstone Holdings, said, “Solid-state batteries have long been the elusive technology breakthrough in the battery category for the better part of a decade. 

“Countless labs, scientists, ventures and corporates have claimed progress towards scalable solid-state batteries, with an emphasis on claims. No other known company has made the type of commercialisation achievements in all-solid-state batteries that Solid Power has.”

In May, Solid Power announced a $130 million Series B investment round led by the BMW Group, Ford Motor Company and Volta Energy Technologies. 

Ford and the BMW Group also expanded existing joint development agreements with Solid Power to secure all-solid-state batteries for future electric vehicles. 

Transaction Overview 

The business combination values Solid Power at an implied $1.2 billion pro forma enterprise value. Upon closing of the transaction and assuming no redemptions by DCRC public stockholders, Solid Power is expected to have approximately $600 million in cash, including a $165 million fully committed PIPE transaction anchored by investors Koch Strategic Platforms, Riverstone Energy Limited, Neuberger Berman funds and Van Eck Associates Corporation.

NeoVolta increases lithium-iron-phosphate battery life to 16.5 years

Battery maker NeoVolta has announced its NV14 energy storage system will include lithium-iron-phosphate batteries that last for 6,000-cycles or 16.5 years.

The system represents a 50% longer life than the firm’s original 4,000-cycle product and represents an engineering milestone for NeoVolta, claim the company.

Neovolta claims the NV14 system has a capacity of 14.4kWh, expandable to 24kWh with the optional NV24 battery, and 7.7kW of instantaneous power discharge.

The claim is based on the home storage batteries being cycled daily, with 6,000 cycles translating to 16.5 years of useful life, based on a full charge and discharge. 

Neovolta did not answer questions put to it by BEST about the technology .

In 2019, a year after it staerrted up, NeoVolta said it was set for a “300% increase in manufacturing capacity” as its moved to a 21,150 sq ft production facility in San Diego.

The move was meant to allow it to increase production of its lithium iron phosphate home battery units to more than 10,000 annually.
