ENERGY<br />
Bringing POWER back to LiFe<br />
<strong>Green</strong> <strong>Economy</strong> <strong>Journal</strong> interviews CEO of REVOV<br />
REVOV was founded by Lance Dickerson, former CTO of MTN, Ghana, and Felix von Bormann,<br />
former engineering consultant for Sprint, USA. Both highly-skilled engineers bring a combined<br />
50 years of experience to power up the energy storage space.<br />
2nd-LiFe batteries are not<br />
recycled batteries, and they are not<br />
second-hand batteries. This is an<br />
important distinction.<br />
that the very technology required to support sustainable electricity<br />
storage and mobility is extractive to the planet and comes with its<br />
own carbon cost. This is why 2nd-LiFe batteries are a compelling<br />
solution for those genuinely interested in “going green” and making<br />
decisions that benefit the planet.<br />
The carbon footprint of a 2nd-LiFe battery is as close to zero as<br />
possible for a storage battery – precisely because it is utilising the<br />
good cells of EV batteries and not relying on newly-mined and<br />
beneficiated components. Besides some new cabling and shipping,<br />
2nd-LiFe batteries are without a doubt the most carbon-friendly<br />
storage solution.<br />
THE SECOND-LIFE EV BATTERY MARKET<br />
The second-life EV battery market is one of great importance<br />
for many reasons. These include adding value to future<br />
energy infrastructure, creating a circular economy for electric<br />
vehicle (EV) batteries, and providing a lower levelied cost of<br />
storage compared to new batteries. The new IDTechEx report,<br />
“Second-life Electric Vehicle Batteries 2023-2033”, highlights<br />
advancements in the second-life industry. IDTechEx forecasts<br />
that the second-life EV battery market will reach US$7-billion in<br />
value by 2033.<br />
The bulk of EVs currently use Li-ion battery chemistries, and once<br />
their eight-to-10-year initial lifetime has expired, they are usually<br />
unsuitable for future EV use. Battery second use (B2U) extends the<br />
lifetime of the EV battery. Depending on the State of Health (SOH)<br />
and residual capacity of the battery, second-life batteries can be<br />
further utilised in less demanding applications, such as stationary<br />
energy storage and lower-power electromobility applications.<br />
Stakeholders must make key decisions regarding the end-oflife<br />
management of retired EV batteries. Second-life batteries<br />
created through a remanufacturing process offer benefits of<br />
maximising battery value and extending battery life, whereas<br />
recycling results in batteries losing this value prematurely. If<br />
remanufacturing is chosen, second-life BESS developers must make<br />
further decisions to ensure that the creation of their second-life<br />
systems is techno-economically feasible. Remanufacturers must<br />
consider several process operations, such as battery procurement,<br />
depth of disassembly, testing/grading, and reassembly procedures.<br />
Please tell us about REVOV. What do you specialise in?<br />
REVOV is an energy storage solutions company that sells lithium<br />
iron phosphate batteries either as single units or in powerful<br />
systems of multiple batteries, headquartered in Johannesburg with<br />
branches in Cape Town and KwaZulu-Natal. REVOV is known for,<br />
and specialises in, 2nd-LiFe lithium iron phosphate batteries for the<br />
B2B market in South Africa and Southern African region. REVOV has<br />
become renowned for its 1st and 2nd-LiFe batteries which provide<br />
a compelling case to bring lithium-iron performance to the market<br />
at a significantly reduced cost. Rand for rand, REVOV is the go-to for<br />
value for money.<br />
What are second-life batteries? Why recycle batteries?<br />
This needs to be clarified at the start: 2nd-LiFe batteries are not<br />
recycled batteries, and they are not second-hand batteries. This is an<br />
important distinction. REVOV does not sell recycled or second-hand<br />
batteries. REVOV sells 2nd-LiFe batteries which are batteries that are<br />
built from repurposed cells of electric vehicle (EV) batteries. In other<br />
words, when an EV battery is replaced, instead of being discarded,<br />
it is taken apart by specialised teams, and individual cells which are<br />
still in perfect working order are removed. In REVOV’s case, we have a<br />
partnership with a world-leading EV battery company in China.<br />
The individual cells taken from the EV battery are then configured<br />
and built into 2nd-LiFe batteries with new casings, parts and battery<br />
management systems. These 2nd-LiFe batteries have a comparable<br />
lifespan to 1st LiFe batteries, and they can withstand harsher conditions<br />
because they are made from the good cells of EV batteries, which are<br />
designed for high temperatures as well as charge and discharge rates.<br />
What are the main environmental impacts associated with electric<br />
vehicle batteries?<br />
From the extraction of the raw materials to cross-country logistics<br />
to shipping and then beneficiation, all the way through to delivery,<br />
batteries come at a significant carbon cost. It is perhaps a great irony <br />
What are the advantages of REVOV’s 2nd-LiFe batteries?<br />
Comparable performance to 1st LiFe batteries at a significantly<br />
reduced cost because we are not affected by lithium supply chain<br />
shortages. The company has full local technical support and design<br />
and engineering teams, this is crucial. REVOV batteries have support<br />
that is local.<br />
IN POWER<br />
Lance Dickerson, CEO of REVOV, in 2016<br />
spent extensive time in the telecoms<br />
industry, spending seven years in West<br />
Africa working for MTN. It was during<br />
this tenure that the the impact of a<br />
failing electrical infrastructure was felt<br />
while trying to keep the MTN networks<br />
up and running. Dickerson investigated<br />
and implemented various types of<br />
backup and redundant electrical systems,<br />
however, the technology at the time was<br />
not sufficiently advanced to be able to<br />
give a reliable and cost-effective solution. On his return to South<br />
Africa in 2011, using the skills developed in the telecoms sector,<br />
Dickerson decided to focus on battery backup systems, in an effort<br />
to reduce reliability on failing grid infrastructure and the cost of<br />
diesel-based backup systems. It was at this point REVOV Batteries<br />
was born.<br />
2nd-LiFe batteries are built from<br />
repurposed cells of electric<br />
vehicle batteries.<br />
