What Is LiFePO4 And Why Is It A Better Choice?
What Is LiFePO4 And Why Is It A Better Choice? All lithium chemistries are not created equal. In fact, most consumers – electronic enthusiasts aside – are only familiar with a limited range of lithium solutions. The most common versions are built from cobalt oxide, manganese oxide and nickel oxide formulations. First, let’s take a step back in time. Lithium-ion batteries are a much newer innovation and have only been around for the last 25 years. Over this time, lithium technologies have increased in popularity as they have proven to be valuable in powering smaller electronics – like laptops and cell phones. But as you may recall from several news stories over recent years, lithium-ion batteries also gained a reputation for catching fire. Until recent years, this was one of the main reasons lithium wasn't commonly used to create large battery banks. But then came along lithium iron phosphate (LiFePO4). This newer type of lithium solution was inherently non-combustible, while allowing for slightly lower energy density. LiFePO4 batteries were not only safer, they had many advantages over other lithium chemistries, particularly for high power applications. Although lithium iron phosphate (LiFePO4) batteries aren’t exactly new, they’re just now picking up traction in Global commercial markets. Here’s a quick breakdown on what distinguishes LiFePO4 from the other lithium battery solutions: Safety and stability LiFePO4 batteries are best known for their strong safety profile, the result of extremely stable chemistry. Phosphate-based batteries offer superior thermal and chemical stability which provides an increase in safety over lithium-ion batteries made with other cathode materials. Lithium phosphate cells are incombustible, which is an important feature in the event of mishandling during charging or discharging. They can also withstand harsh conditions, be it freezing cold, scorching heat or rough terrain. When subjected to hazardous events, such as collision or short-circuiting, they won’t explode or catch fire, significantly reducing any chance of harm. If you’re selecting a lithium battery and anticipate use in hazardous or unstable environments, LiFePO4 is likely your best choice. Performance Performance is a major factor in determining which type of battery to use in a given application. Long life, slow self-discharge rates and less weight make lithium iron batteries an appealing option as they are expected to have a longer shelf life than lithium-ion. Service life usually clocks in at five to ten years or longer, and runtime significantly exceeds lead-acid batteries and other lithium formulations. Battery charging time is also considerably reduced, another convenient performance perk. So, if you’re looking for a battery to stand the test of time and charge quickly, LiFePO4 is the answer. Space Efficiency Also worth mentioning is LiFePO4’s space-efficient characteristics. At one-third the weight of most lead-acid batteries and almost half the weight of the popular manganese oxide, LiFePO4 provides an effective way to make use of space and weight. Making your product more efficient overall. Environmental Impact LiFePO4 batteries are non-toxic, non-contaminating and contain no rare earth metals, making them an environmentally conscious choice. Lead-acid and nickel oxide lithium batteries carry significant environmental risk (especially lead acid, as internal chemicals degrade structure over team and eventually cause leakage). Compared to lead-acid and other lithium batteries, lithium iron phosphate batteries offer significant advantages, including improved discharge and charge efficiency, longer life span and the ability to deep cycle while maintaining performance. LiFePO4 batteries often come with a higher price tag, but a much better cost over life of the product, minimal maintenance and infrequent replacement makes them a worthwhile investment and a smart long-term solution. Check out our latest infographic with more details on what makes lithium iron batteries the best choice for your application.

Electric Mining Equipment is Poised to Power the Industry
Electric Mining Equipment is Poised to Power the Industry Traditionally dependent on fossil fuels to run key equipment, mining is known as a carbon-intensive industry. New trends, such as battery-powered underground mining equipment, are promising to disrupt that paradigm. Increasingly, stakeholders are demanding that mining companies be more responsible and sustainable. Companies are being pressured by stockholders, workers, local communities, consumers and governments to reduce greenhouse gas emissions, reduce carbon footprints, improve air quality and protect the health and safety of workers and people living near mines. Meanwhile, others in the mining value chain — such as jewelers, electronics companies, or automakers — want assurances that the minerals they’re buying are mined responsibly. With this as a backdrop, battery-powered underground mining equipment is starting to replace vehicles with diesel engines and equipment with electric motors is starting to replace those using hydraulics. Deeper reasons why companies are switching to electric mining equipment There are other reasons why the switch to electric mining equipment makes sense for many mining operations. One, for instance, is the competitiveness of the industry and the increasing need for miners and equipment to go ever deeper into the earth to extract more minerals. It follows that the deeper a mine, the more ventilation infrastructure is needed to help vent diesel emissions and keep workers safe. According to one estimate, up to 30% of an underground mine’s total operating costs go toward powering ventilation systems to maintain air quality. At some point, it becomes much less cost-effective for such operations to continue using diesel ICE — even equipment that is designed to comply with current Environmental Protection Agency emission standards — in these applications. Surface mining operations aren’t totally immune from these pressures either. Diesel-powered machines used in these operations must adhere to the same environmental regulation as construction and agricultural equipment. A cleaner, greener, safer future of mining Mining is traditionally a very carbon-dependent industry, with heavy reliance on diesel ICE to power its equipment. That reliance may be starting to change, however, driven by pressure from stakeholders to reduce carbon footprints and protect workers and communities, along with new economic pressures derived from the need to mine farther underground. Already, major OEMs are providing electric mining equipment. As new options for charging these large batteries — including renewable resources — become more widespread, expect to see a cleaner, greener, safer future of mining.

This will solve 2 very impotant difficults that electrical underground vehicles are facing now: -Safty; -Fast charge. Here reports come from Bloomberg (Bloomberg) — Electric vehicles are reaching global markets far and wide — and deep. Swedish mining equipment maker Epiroc AB now aims to electrify all its underground machines within five years. The manufacturer on Wednesday launched a new range, including what it says is the largest battery-powered vehicle for mining below the Earth’s surface: a 42 ton-capacity truck that can haul blasted rock through narrow tunnels. It’s part of the company’s latest series of mobile excavators, including drill rigs and loaders, designed to cut emissions and lower energy costs for miners. Reducing the use of diesel fuel could have significant cost benefits for the industry: as much as 40 percent of an underground mine’s energy outlay is spent on powering gigantic ventilation systems to remove pollutants from tunnels. The push for electrified mining got a further boost last month from an industry lobby, the International Council on Mining and Metals, which plans to minimize the impact of underground diesel exhaust by 2025. “Next year we will start production of an 18-ton loader and we will start offering medium-sized drill rigs with battery options,” Sami Niiranen, who has been appointed to lead Epiroc’s underground equipment unit, said in Orebro, Sweden. Epiroc, which is using power packs assembled by Northvolt AB, said the upfront cost of buying a battery-powered vehicle would be about twice that of a conventional one. While this is compensated by lower fuel and energy costs down the road, the initial pain could be prohibitive. In a bid to boost sales, Epiroc will lease batteries for its new range of vehicles separately, making the initial outlay only slightly higher than for an equivalent diesel machine. Bigger, Heavier The new electric vehicles are bigger and more powerful than Epiroc’s first models that hit the market in 2016 and are used by customers including Brazilian mining company Nexa Resources. So far, they make up only a small part of sales for Epiroc, which has worked on electrification since 2013. Their best hope are new or expanding mines that aren’t already equipped with expensive ventilation systems. Cross-town Swedish rival Sandvik AB has delivered hundreds of vehicles powered by electric cables, and has plans to launch its own battery-powered machines. The Nordic companies dominate global sales of underground mining equipment, with a combined three quarters of the market. They compete with Caterpillar Inc. and Japan’s Komatsu Ltd. The International Council on Mining and Metals also aims to achieve greenhouse gas-free vehicles for surface mining by 2040. Yet the transition to electric vehicles still has some way to go. Bringing the biggest hauls of rock up steep ramps and out of the ground requires power that existing batteries are ill-equipped to supply. This has led to renewed interest in trolley systems whereby electrified trucks are connected to a power grid with overhead cables. Swedish mining company Boliden AB has a project using Caterpillar trucks and ABB Ltd. power infrastructure to haul ore from Aitik, the country’s largest open pit copper mine.
