Lithium Battery Capabilities

Epec offers a wide range of lithium battery solutions, most specifically custom battery packs that utilize both primary and secondary lithium batteries, which are two types of rechargeable batteries that differ in their chemistry and construction. While both types of batteries use lithium as their primary active material, they have distinct characteristics and are used in different applications.

By now, most people are aware that lithium batteries are known to be volatile and can catch fire or explode if not handled properly. Therefore, ensuring the safety of the battery pack is of utmost importance when designing a lithium battery pack. Epec will ensure that the battery pack is designed with the proper safety features, such as overcurrent protection, overcharge protection, and thermal management systems.

Primary Lithium Batteries

Primary lithium batteries, also known as non-rechargeable lithium batteries, are designed for one-time use, and cannot be recharged. They are often used in applications where long-term reliability and stability are critical, such as in military and aerospace applications. Primary lithium batteries have a higher energy density and a longer shelf life compared to other battery chemistries.

Primary lithium batteries use lithium metal as the anode and a non-aqueous electrolyte to conduct ions between the anode and cathode. The cathode material used in primary lithium batteries can vary, but common materials include manganese dioxide, thionyl chloride, and sulfur dioxide. Primary lithium batteries have a higher voltage and energy density compared to secondary lithium batteries, but their capacity is limited.

Best Applications for Primary Lithium Batteries

Primary lithium batteries are best suited for applications that require long-term reliability and stability. These batteries are commonly used in:

  • Military and aerospace applications
  • Medical devices, such as pacemakers and hearing aids
  • Remote sensors and monitoring devices
  • Emergency backup systems
  • High-performance flashlights

Secondary Lithium Batteries

Secondary lithium batteries, also known as rechargeable lithium batteries, are designed to be recharged and used multiple times. They have a lower energy density and a shorter shelf life compared to primary lithium batteries but have a higher capacity and are more cost-effective over their lifetime.

Secondary lithium batteries use lithium ions as the active material, which are transferred between the anode and cathode during charging and discharging cycles. The anode material used in secondary lithium batteries is typically graphite or a lithium metal oxide, while the cathode material can vary, depending on the application.

Common cathode materials used in secondary lithium batteries include:

  • Lithium cobalt oxide (LCO): Used in high-performance applications, such as laptops and smartphones.
  • Lithium manganese oxide (LMO): Used in power tools.
  • Lithium iron phosphate (LFP): Used in stationary energy storage systems and medical devices.
  • Lithium nickel manganese cobalt oxide (NMC): Used in grid-scale energy storage systems.

Best Applications for Secondary Lithium Batteries

Secondary lithium batteries are best suited for applications that require high capacity, rechargeability, and cost-effectiveness. These batteries are commonly used in:

  • Consumer electronics, such as smartphones, laptops, and tablets
  • Power tools and other cordless devices
  • Energy storage systems, such as grid-scale storage and home energy storage
  • Medical devices, such as wearable devices and insulin pumps

Lithium Battery Management Systems

Epec's battery management systems (BMS) provide advanced battery protection and monitoring capabilities, ensuring the safe and reliable operation of battery packs. The BMS can also optimize battery performance, extending the battery's lifespan and reducing maintenance costs. Epec's custom battery packs are designed to meet specific customer requirements, providing the perfect solution for unique applications.

Development of Lithium Battery Packs

Developing a lithium battery pack requires expertise in many areas, including electrical engineering, mechanical engineering, and chemistry. A battery pack must be designed to meet the requirements of the application, including voltage, current, energy density, and size. The battery pack must also be designed to ensure the safe and reliable operation of the battery cells. We have many different resources on this process and what customers need to consider when developing custom battery packs such as:
