Chemistry Selection

As the EV industry pushes forward with lightning speed, the world cannot ignore the potential and significance of the ever-popular Lithium secondary category, which contains the choices of Lithium Ion, Lithium Polymer, and Lithium Iron Phosphate.

While this new and current generation of chemistry provides a higher operating voltage level and energy density, lower self-discharge rate, the biggest win is about significant size reduction to make the end device smaller and lighter. Lithium Iron Phosphate stands out with a larger size and weight characteristics but offers unmatched high discharge current capability, with better safety and life span performances.

While there is no one size fits all chemistry, it is vital for a company to identify the most critical areas of benefit that will trade-off against the loss.

Lithium Ion (Li-Ion) cells have a negative electrode (anode) made from lithium compounds. Lithium is a highly reactive material and is much lighter than the hydrogen-absorbing metal alloy of the NiMH negative electrode. This leads to higher gravimetric energy densities for the Li-Ion cell. Cells can stay in storage for 12 months without requiring maintenance. The expected cycle life of a Li-Ion in an application is about 500+ full charge and discharge cycles.

The lithium iron phosphate battery is a type of rechargeable battery based on the original lithium ion chemistry, created by the use of Iron (Fe) as a cathode material. LiFePO4 cells have a higher discharge current, do not explode under extreme conditions and weigh less but have lower voltage and energy density than normal Li-ion cells.

Iron (Fe) is an intrinsically safer cathode material than Cobalt (Co). The Fe-P-O bond is stronger than the Co-O bond so that when abused (short-circuited, overheated, etc.) the oxygen atoms are much harder to remove. This stabilization of the redox energies also helps fast ion migration. Only under extreme heating, generally over 800C, does breakdown occur which prevents the thermal runaway that typical Li-Ion cells are prone to.

LiFePO4 is highly resilient during oxygen loss which typically results in an exothermic reaction in other lithium cells. No PCM is needed but recommended to maintain cycle life and capacity.

Printed Circuit Board Assemblies

A Fortune 300 life sciences company wanted to change contract manufacturers due to quality and delivery issues.

"Without Eastek's extensive Engineering team and being able to reverse engineer all of our boards, we would have spent time, energy, and money in legal fees and wouldn't be as far as we are today."

General Council

Custom Battery Pack Solution

A multinational medical technology company needed a robust battery solution that would improve cycle life of the battery and provide all-day, high-power performance.

"Eastek was able to educate and guide us on what the best battery technology would be for our applications. They were an essential part of making sure multiple products functioned with the same battery."

Chief Technology Officer

We’ve Lost our IP

Eastek was able to reverse engineer the customers product line, enabling them to regain control of their IP for the first time in 20 years.

"Without Eastek, I'm not sure how we would have continued forward. Not only were we able to continue future generations of our product, but we now have our IP back in our hands and under our control."

Frequently asked questions

Off-the-shelf solutions are often bulky, aside from not being space efficient, meeting the power requirement of the end product is another challenge.  Therefore, a customized solution will provide improved size, weight, performance while keeping development and production costs under control.

Communication capability, safety and longevity…

Always, always follow the original specification provided by the chosen cell manufacturer.  Then design and develop with high regards to voltage, current and temperature management.  When it comes to safety, there is no shortcut…

Prolonged storage maintenance feature – “Deep Sleep” implementation to avoid “bricking” – Ultra ultra low quiescent current drain during off mode by passive and active control mode

We pride ourselves with dedicated focus on Tier 1 and Tier 2 cell supplier network and supply chain management, in order to provide material excellence and production continuity.
