May 2017 – Lithium Iron Phosphate (LiFePO4) trending for new product introductions

There is an emerging trend for safety critical applications to move straight from existing chemistries to Lithium Iron Phosphate.

In the past we saw design authorities taking their development plans in stages…Typically:

NICAD –> NI-MH –> LITHIUM ION or LITHIUM POLYMER

Now we are seeing the Ni-MH component being skipped in favour of a jump straight to Lithium Iron Phosphate.

There are several advantages of LiFePO4 in terms of its green credentials and most importantly its failure mode with no potential for thermal runaway, which is associated with other lithium chemistries.

Lithium Polymer and Chemistries such as Lithium Cobalt Oxide still have a strong place with their built in protection circuitry and higher energy densities, but there is no doubt that more and more safety critical applications are looking seriously at Lithium Iron Phosphate for new products.

We have many successful design-wins in this area and can support with 3d modelling to help to speed up your time to market and internal design discussions.
