Lithium Ion Batteries

A Change

Lead Acid to Lithium Ion

Currently in Indian scenario, most of the applications are designed around lead acid batteries due to its low initial cost, ease of availability and low integration hassles. It has been greatly observed that, this leads to applications often under-performing, causing break-down, and not being able to achieve its full capability. This phenomenon is evident in various applications as back-up supply/ UPS (at all levels: small, medium to large scale), solar power storage, electric vehicles, etc.

In such a changing and demanding situation, where applications are often market driven, the need for a more reliable alternate for energy storage is growing now more than ever before. While choosing an alternative energy storage device, system designers and integrators often find it difficult and often confusing to identify the right energy storage device to fit into their need of application. Some of the alternate energy storage devices include lithium-ion batteries, sodium sulfur batteries, vanadium redox batteries, super-capacitors, etc.

Generally, the broad design considerations are based on the following key requirement parameters:

  • Charge time – Time available to charge the batteries
  • Discharge requirements/ Rate performance – Greater “C” rates for quick acceleration
  • Cycle life – Need for long life
  • Operating time – Long life between charges, due to greater depth of discharge
  • Operating temperatures – Depending on the application, from -40°C to +65°C
  • Weight – effecting mounting and mobility issues.
  • Footprint/available space – volume reduction when space matters
  • Modularity/Scalability – Ease of system integration, expansion and relocation
  • Service/maintenance – projected life for specific operating temperatures and accessibility for servicing and maintenance
  • Cost – One of the most important factor, which is often judged by the initial cost alone. However, to arrive at a proper costing of the storage device, the initial cost should be apportioned over the entire operating time (including the maintenance and service costs) has to be considered.
  • Lateral integration – Other system changes and maintenance to be made to incorporate the storage device.

Considering the above parameters, the next generation Lithium Ion batteries fit into the alternate choice perfectly.
