The EV Battery Supply Chain

The EV battery supply chain is complex and reliant on many different components. When any one of these areas experiences a disruption, it can cause delays that ripple throughout the entire chain.

Effective logistics companies can help to reduce operational costs and ensure efficient delivery from production to end-use applications. This article will explore the many aspects of this rapidly growing sector, from raw materials to distribution networks.

Alkaline Batteries

Alkaline batteries are used in many household devices such as calculators, bathroom scales, toys and remote controls. These are disposable and non-rechargeable batteries that offer a long shelf life and high energy density.

They are a major improvement over zinc-chloride cells, offering three to five times more capacity. This is because of the use of an alkaline electrolyte that is more conductive than the acidic zinc chloride solution found in traditional batteries. They also use a different cathode material, allowing them to deliver more current without overheating.

While they do not have the same energy capacity as rechargeable batteries, these batteries are available in a wide range of sizes. They are usually referred to as AA, AAA, C and D cells, but they can be produced in other forms as well. These include button cell, cylindrical, and PP3 batteries.

Alkaline batteries are subject to a variety of regulations regarding their manufacture, use and disposal. This includes environmental and safety standards that aim to minimize the impact of these batteries on the environment. These batteries are a non-toxic alternative to rechargeable batteries and should be recycled when they are no longer needed. They contain a number of metals and chemicals that should be reused rather than depleting the earth’s natural resources. Consequently, the batteries should not be placed in landfills and should be taken to designated recycling facilities.

Lithium Ion Batteries

Lithium batteries are one of the most efficient rechargeable battery technologies available. They are light, retain their charge and are reliable for devices like phones and laptops. They are also used to power electric and recreational vehicles. They offer greater reliability than nickel-metal hydride batteries, which can lose up to 20% of their charge each month.

When a lithium battery is charged, lithium ions are transferred from the anode to the battery supplier cathode through an electrolyte, causing a potential difference that produces current. During discharge, the process reverses, with lithium ions returning to the anode.

A single lithium cell can produce up to 3.6 volts, which is enough to operate most electronic devices. But a full battery pack needs a number of cells stacked together, depending on the size of the device and the type of electrode materials used.

These batteries are found in many of the everyday products that consumers and first responders use and depend on. But improper handling, charging and storage can lead to fires or explosions. NFPA offers several resources to help educate people about battery safety.

Nickel Metal Hydride Batteries

Nickel metal hydride batteries (NiMH) are the main battery used in portable electronics and hybrid electric vehicles. Their high energy density allows them to power a large number of electrical devices and also provides the needed additional power for HEVs to achieve high fuel economies.

Unlike lithium-ion batteries, Nickel-metal hydride batteries do not suffer from the memory effect that affects Li-ion batteries. In addition to having excellent cycle life, they are able to tolerate higher discharge rates, providing the ability for long-term storage of energy.

The primary components of a NiMH battery are anode, cathode, and separators. The anode is made up of a complex alloy of many different metallic elements including V, Ti, Zr, Ni, Cr, and Fe. The chemistry of these materials allows for tailoring of the hydride to meet specific needs in a battery application such as low equilibrium pressure and resistance to corrosion.

The cathode is made of a manganese oxide material and the electrolyte is a nickel-cadmium-free system. This system eliminates the cadmium from the cell, making it an environmentally friendly option and facilitates recycling procedures for spent batteries.

These batteries also do not require a memory charger and can be recharged at any point during the usage cycle.

Lead Acid Batteries

Lead acid batteries are an irreplaceable link to connect, protect and transport the tools that power our modern way of life. They provide an intense burst of high power for starting motor vehicles, then recharge as the vehicle drives. They are also used in deep cycle applications like trolling motors, camper and boat accessories or to run light fixtures and golf carts. Lead-acid battery cells consist of a sponge lead anode and a lead acid cathode immersed in a dilute sulfuric acid electrolyte. An electric current runs between these plates, converting lead oxide on the cathode to lead sulfate and producing hydrogen during discharge. During recharging, the hydrogen gas produced attacks the lead sulfate crystals to produce water.

These batteries must be properly maintained to ensure they remain in good condition. Incorrect handling or abusive treatment can cause leakage of the dangerous sulfuric acid electrolyte. This can lead to severe chemical burns and a fire hazard.

Several types of sealed lead acid batteries have emerged to address this concern. Gel-cell and absorbent glass mat (AGM) lead-acid batteries have become the norm for many applications because they offer low maintenance with long battery life. They are ideal for backup power applications such as cellular repeater towers, Internet hubs, banks, hospitals and airports. These batteries are also commonly used in UPS systems and emergency lighting.
