SAN DIEGO, Nov. 04, 2019 (GLOBE NEWSWIRE) — With extreme winds stoking wildfires across the state throughout October, California utilities have resorted to public safety power shutoffs on an unprecedented scale. The governor has declared a statewide emergency, and Californians are wanting to make their homes resilient against extended blackouts. How long can a home survive a grid shutdown using solar panels combined with battery storage? Some batteries provide longer backup than others. Two popular systems on the market, for example, have capacities of 10 kilowatt-hours (kWh) and 13.5 kWh. With the average home drawing 750 to 1,000 W of power per hour during a blackout, the 10 kWh battery will last 10 to 12 hours and the 13.5 kWh battery will last 13.5 to 16.8 hours. Both of those batteries are rated at 5 kW, a load that has been compared to running a clothes dryer, a microwave, and a hair dryer at the same time. But one new residential storage system stands out for superior power and capacity. NeoVolta’s NV14 solar home battery has a high storage capacity of 14.4 kilowatt hours (kWh), meaning it could last 14.4 to 18 hours operating in blackout conditions. And because the NV14 delivers 7.6 kW of continuous power, it can drive more household loads during that time than its 5 kW competitors. When the lights go out for any reason, the NV14 automatically disconnects from the grid to immediately start powering a home’s critical loads. The switch is seamless, unlike some other systems where there is an interruption of power. Homeowners who need more storage capacity can add a second battery system, NV24, and avoid the expense of installing another entire system (inverter and battery); this option will be available in December 2019. NV14 combined with NV24 brings the energy storage capability up to 24.0 kWh. Note: An extended whole-home backup is not currently available with any battery storage system, so some appliances and creature comforts will have to wait until after the emergency. What every storage system must do is provide the basics—lights, internet, refrigeration, other kitchen outlets, and garage—for as long as possible based on their specifications. The NV14’s advanced lithium iron phosphate battery is designed for safety and a longer life cycle than ordinary lithium ion batteries. The system can connect with any residential solar installation—new or existing, AC or DC. With the NeoVolta smartphone app, users can monitor the system’s performance 24/7. The NeoVolta NV14 is also a sound investment. When the grid is up and running, homeowners can see significant savings on their monthly utility bill. That’s because the energy generated while the sun is shining can be stored in the NV14’s battery and used during evening “peak demand” hours when utility rates are often twice as high. “To get through a prolonged blackout, your home needs an energy storage system. Without it, those solar panels are nothing more than roof ornaments,” said Brent Willson, CEO of NeoVolta. “The high-power, high-capacity NV14 system delivers comfort and peace of mind, providing reliable power that could potentially be lifesaving.” About NeoVolta – NeoVolta designs, develops and manufactures utility-bill reducing residential energy storage batteries capable of powering your home even when the grid goes down. With a focus on safer Lithium-Iron Phosphate chemistry, the NV14 is equipped with a solar rechargeable 14.4 kWh battery, a 7,680-Watt inverter and a web-based energy management system with 24/7 monitoring. By storing energy instead of sending it back to the grid, consumers can protect themselves against blackouts, avoid expensive peak demand electricity rates charged by utility companies when solar panels aren’t producing, and get one step closer to grid independence.

Lithium-ion batteries have earned and substantiated their label as a “green technology.”  The US Environmental Protection Agency (EPA) considers lithium-ion batteries “safe” for disposal in contrast to nickel-cadmium and lead-based battery products, which  can cause environmental issues with careless disposal.

In the US, we typically do not see consumer electronics recycling as much of a money maker. Some electronics makers charge a premium for devices that include “ease of recycling” among their green credentials, while others charge to reclaim their devices for recycling. Nevertheless, as the auto industry races toward bringing hybrid and electric vehicles to market, environmentalist groups and government agencies such as the Department of Transportation, worry about the ability to properly recycle the lithium-ion batteries that power those cars. Unfortunately, there is almost no recycling infrastructure in place today. Does this mean that we have we reached the birth of the lithium-ion battery recycling industry? Some experts say that the need is still a decade away, while others are currently beginning to design and build recycling facilities.

The Economics of Recycling
At a minimum, recycling batteries is appropriate for two reasons. First, Americans will demand it, especially since the impetus for the development of lithium-ion and electric car technology are, at their very nature, environmentally friendly. Second, recycling makes economic sense if the revenue from the recovered materials, plus the avoided disposal costs, is greater than the cost for collection and processing. Although the developed world has a robust system to manage lead-acid battery recycling (more than 99 percent of lead-acid batteries are recycled in the US), the lithium-ion battery has a long way to go to catch up(1). Lead-acid batteries are essentially blocks of valuable metals; lithium-ion batteries simply do not contain much valuable metal to make them economically useful.

Lithium-ion batteries are not nearly as toxic as lead-acid batteries, so not only is the urgency to recycle not there, but in fact, lithium-ion batteries are classified by the US Government as safe to dispose of in conventional landfills. So, is that good news or bad news?  Maybe both. Each year, Americans annually dump two billion lithium-ion batteries into the waste stream(2). However, the scrap value of lithium-ion batteries is perhaps only $100/ton, compared to $1,000 to 3,000/ton for lead. By contrast, the cost of collecting, sorting and shipping lithium-ion batteries to a recycler far exceeds the scrap value. However, this could be off-set by the fact that the cost of other materials in lithium-ion batteries, such as cobalt, have a lower recycling cost than mining new material.

Global Lithium Supply and Demand
It may be time to look to the future. With our mobile lifestyle (driving the development of portable electronics) and the predicted increase in demand for electric vehicles, will the cost of lithium increase and thus making recycling more economically attractive? In 1975, the US Geological Survey convened a symposium on lithium demand and resources. Their concern was that by the year 2000, there would not be enough lithium to meet the demand for fusion power and load-leveling lithium storage batteries. In 1985, there was another predicted shortage when aluminum-lithium alloys were forecast to be used in aircraft construction. Recently, concern was expressed again about lithium availability because of the potential large scale use of lithium-ion batteries in electric and hybrid vehicles.

However in a recent study performed by Argonne National Labs, the global supply of lithium was found to be more than adequate to meet the demand to 2050, even with the optimistic view of how quickly electric vehicles will be adopted(3). Bolivia has the world’s largest reserves of lithium, followed by Chile and Tibet. Lithium-ion batteries account for only 25 percent of the worldwide demand for lithium, but that percentage has risen quickly over the past 10 years. Ceramics, glass and lubricating greases are other major uses of lithium and collectively account for 30 percent of global lithium demand.  While 2050 may seem like a long way off, in that time 10 million metric tons of lithium will have been thrown away.

Lithium Economics
Is it wise to begin taking the necessary steps to develop an infrastructure for recycling now? The US Department of Energy recently granted $9.5 million to a company in California that plans to build a recycling center for lithium batteries. With $2 billion of grants awarded for the development of lithium batteries, this seems like a drop in the bucket, but it is a start. Although, the lithium part of a battery pack is a negligible cost when compared to other metals; nickel and cobalt tend to be the bigger drivers of recycling.

Cobalt, a by-product of copper and nickel mining, is a scarce metal and half of the global supply comes from politically unstable regions of the world.  In addition, some lithium-ion chemistries are even less cost effective to recycle. For example, lithium iron phosphate batteries will not yield a high recycling return, and while this chemistry has advantage over other competitive products, it also makes it less economical to recycle.

In Europe, lithium battery recycling is supported through subsidies. Even with rising prices for metals, subsidies, in the form of a tax added to each cell manufactured, are still necessary and are collected from manufacturers, agencies and governments to support the recycling programs.

Current Status and the Future of Lithium Recycling
Current battery recycling methods require high amounts of energy. It takes six to 10 times the amount of energy to reclaim metals from recycled batteries than it would through other means of metal reclamation processes(4). The current process of recycling batteries starts by removing the combustible material, such as insulation and plastic, with a gas-fired thermal oxidizer. This process leaves the clean cells containing the metals. The cells are cut into smaller pieces and then heated until the metal liquefies.

After removing the slag, the different alloys settle according to their weights and are skimmed off. Cadmium is light and vaporizes at high temperatures. The cadmium vapor is collected, cooled and condensed to a very pure form.

Let’s face it; recycling larger lithium-ion automotive batteries has to be much easier than recycling smaller lithium-ion cells. The collection mechanism and logistics has to be more straightforward, and more in line with  the lead-acid recycling model. Secondly, the large format will warrant separation by type to maximize the value of the recovered materials, which will be in fairly large pieces to justify product disassembly. It is even plausible to remove the cell windings to recover the clean aluminum from the cans.

The investment and innovation pouring into lithium-ion technology for electric cars could be a major advantage for the emerging green power grid. When an auto battery degrades and needs to be replaced, the auto companies could find a healthy market in the utility grid for recycled lithium-ion batteries for use in energy storage. This may eliminate the lithium recycling stumbling block the auto industry is facing. Enter: recycle and reuse.

Future Work
As an industry, we need to make sure the newly developed lithium-ion batteries can be recycled. There has to be a complete estimate of the material available for recycling and the economics of doing so, and these estimates must include the possibility of reuse for lower-duty performance applications. Building on past work and recycling processes, we need to understand the total energy, social and environmental costs to maximize recovery and minimize impact. The lithium-ion recycling revolution may not quite be here today. But, “a revolution is not an apple that falls when it is ripe. You have to make it fall.” – Che Guevara
