Applications of Battery Materials


Batteries are an area of significant research and are used in a range of applications as electrical energy storage mediums. Lithium cathodes have become the dominant battery material because of their large energy capacity and high operating voltages relative to other battery types. As a result, lithium-ion batteries are being developed for use in HEVs, EVs, energy storage, consumer electronics, and power tools.

Hybrid and Electric Vehicles

HEVs and EVs require a high capacity, to enable longer drive distances; a high cycle rate, to reduce battery replacements; and a high voltage, to allow for higher current draws. These batteries must also be safe and achieve suitable energy density.

While efforts are ongoing to perfect a singular battery type, it is common to employ multiple different battery chemistries to achieve separate tasks. By using multiple battery types and smart charging methodology, an EV can sustain its battery life for the required time.

Energy Storage and Renewable Energy

Energy storage systems are becoming increasingly important as the need for accessible energy increases. Batteries can be used to address the mismatch between renewable energy generation and energy demand.

By storing energy during peak generation times, battery energy storage systems can provide electricity during times when demand exceeds energy generation. With storage systems, the overall capacity, reliability, and cycle life must be optimized.

High Power

Batteries used in high-powered applications require a large current draw or a high C value. To allow for this, the battery structure needs to be resilient and allow for fast ion mobility. Common applications include RC aviation and power tools, such as cordless drills.

Consumer Electronics

Consumer electronics, like phones and laptops, need smaller and more efficient batteries with faster charging times. Energy density and the capacities at fast current draw rates, as well as the nominal usage, are important as fast charging requires a large current flow.
