BU-808b: What Causes Li-ion to Die?

Blog EVPower

Learn what‘s behind the aging process of Li-ion

Source:

The ultimate focus of maximizing the energy density of Li-ion shifted in 2006 when Li-ion unexpectedly disassembled in consumer products and millions of packs were recalled. Safety gained attention and batteries became safer. With the advent of the electric vehicle (EV), longevity is moving to the forefront and experts have begun exploring why batteries fail.

While a 3-year battery life with 500 cycles is acceptable for laptops and mobile phones, the mandated 8-year life of an EV battery seems long at first. However, it still makes an EV buyer cringe when learning that a replacement battery carries the price of a compact car with an internal combustion engine. If the life of the battery could be extended to, say, 20 years, then driving an EV would be justified even if the initial investment is high.

Manufacturers of electric vehicles choose battery systems that are

BU-304a: Safety Concerns with Li-ion

Source:

Learn what causes Li-ion to fail and what to do in case of fire.

Safety of lithium-based batteries has attracted much media and legal attention. Any energy storage device carries a risk, as demonstrated in the 1800s when steam engines exploded and people got hurt. Carrying highly flammable gasoline in cars was a hot topic in the early 1900s. All batteries carry a safety risk, and battery makers are obligated to meet safety requirements; less reputable firms are knowns to make shortcuts and it’s “buyer beware!”

Lithium-ion is safe but with millions of consumers using batteries, failures are bound to happen. In 2006, a one-in-200,000 breakdown triggered a recall of almost six million lithium-ion packs. Sony, the maker of the lithium-ion cells in question, points out that on rare occasion microscopic metal particles may come into contact with other parts of the battery cell, leading to a short circuit within the cell.

Battery manufacturers strive to minimize the presence of metallic particles. The semiconductor

Batteries: Lithium-ion vs AGM

Blog EVPower
Source:

Across all markets over recent years Lithium-ion batteries have been gaining in traction [sic]. To the uninitiated it is easy to dismiss Lithium-ion as an expensive alternative to VRLA (valve regulated lead acid) technologies such as AGM (absorbed glass mat), if simply looking at the amp-hour (Ah) rating. This was the initial mistake I made a few years back. Digging deeper it became clear to me that there is a lot more than Ah ratings to consider, when choosing the best batteries for your application.

What’s inside an 18650 cell? And why its important

Blog EVPower

Source:

There has been a boom in ebike builders making their own battery packs out of the popular 18650-format cells (18mm diameter, 65mm long), and I want to share what I’ve found out about the guts of an 18650, so you will understand more about proper DIY pack-building methods.


Why would somebody make their own pack?

The existing battery pack vendors will only make (and stock) the packs that they think they will sell enough of, to make it worth risking their available cash. Which means, they will only have packs with certain particular sizes, shapes, and with specific cost-effective cells.

BU-205: Types of Lithium-ion

Become familiar with the many different types of lithium-ion batteries.

Source:

Lithium-ion is named for its active materials; the words are either written in full or shortened by their chemical symbols. A series of letters and numbers strung together can be hard to remember and even harder to pronounce, and battery chemistries are also identified in abbreviated letters.

For example, lithium cobalt oxide, one of the most common Li-ions, has the chemical symbols LiCoO2and the abbreviation LCO. For reasons of simplicity, the short form Li-cobalt can also be used for this battery. Cobalt is the main active material that gives this battery character. Other Li-ion chemistries are given similar short-form names. This section lists six of the most common Li-ions. All readings are average estimates at time of writing.
