Temperature-controlled supply chain is more important than ever during with today’s volatile supply chain. On-line ordering of pre-prepared food, beverage clubs, and medicine distribution are all increasing the need for cold-chain technology. Lithium-ion batteries charge faster, and opportunistically, and have longer run-time than traditional lead acid batteries, optimizing equipment utilization Batteries don’t need to be swapped, watered, or equalized at room temperature, so maintenance is simplified. Cold-temperature cycle life is vastly improved for a lower total cost of ownership. This is a brief overview of how to implement and take advantage of this new technology.

Future-Proofing Your Fleet: Long term Viability of Li-ion Technology in the Material Handling Industry and Ground Support Equipment Industries
For nearly two decades, I have focused on battery technology and the battery industry. I have a PhD from The University of Texas at Austin, where I studied with John Goodenough, who won the Nobel Prize for inventing the Lithium-ion (Li-ion) battery. When I was in graduate school, in the late 90 and early 2000s, Li-ion batteries were not yet used commercially; laptop computers were powered by NiMH batteries and NiCd powered tools, camcorders and remote-control cars. GM had a robust research program on electric vehicles, which was ultimately canceled in 2002 because of poor market acceptance. No one knew which technology would power the emerging consumer electronics market- most thought NiMH batteries would stay as the default and big companies invested in everything from fuel cells to MEMs fly-wheels.
The Beginning of the Li-ion Battery Industry
Then, a number of key innovations resolved some of the safety concerns about Li-ion batteries, SONY commercialized the first Li-ion cells and the die was cast. Nearly all laptops were powered by Li-ion batteries within just a few years, and Li-ion batteries enabled cell phones which came on the market a bit later. The sheer volume of these two applications, enabled the market Li-ion battery market itself to mature, so that now nearly everything that needs portable or back-up power uses Li-ion. The only exception to this adoption is long term legacy lead acid stationary back up power and heavy equipment motive applications, like material handling and ground support equipment. Lead acid still has a lower up front cost and these applications don’t really benefit from the size and weight advantages of Li-ion batteries.
What will Happen Next in the Li-ion Battery Industry?
As motive applications like material handling and ground support equipment become the last hold outs for an older technology with a decidedly poorer environmental profile, I believe that we will see total costs for lead acid batteries increase. The infrastructure that is built up around the lead acid market (recycling, etc.) will shift to support the Li-ion battery industry. Li-ion batteries will have more suppliers and more diverse product offerings, more competition and more supply chain redundancy. Adjacent technology for Li-ion will improve and manufacturing methods will gain efficiencies. The US government is already beginning to invest heavily in strategic, domestic Li-ion manufacturing. When the governments of leading countries can start to ban and regulate Lead Acid, they will. In fact, RoHS and other regulations have specific call-outs for lead in batteries just because there has not been a viable alternative, until now. China has already begun to take drastic steps to completely ban lead acid battery manufacturing. Lead acid manufacturing will likely be only in far-away places with inexpensive labor and poor environmental regulations and high shipping and import costs. In the industry, there is no more debate about if Li-ion batteries will overtake Lead acid, the question is more when and how. The volume of Li-ion batteries being produced will be an advantage to the material handling and ground support industries long term, rather than a risk.
Will a New Technology Replace Li-ion Batteries?
The conversion of the entire industry from lead acid to Li-ion will be long, so you may wonder if there will be another, new technology that will leapfrog it, and my prediction is that there will not. Inventions in this science are very slow and tend to be incremental; it has taken China 25 years to get its mature Li-ion battery industry. If there were something coming up behind Li-ion batteries, it would already be far into development. I do believe that fuel cells will be a key part of the new zero carbon fleets, but they will replace ICE primarily and co-exist with Li-ion battery powered trucks. Because hydrogen infrastructure requirements are similar to gas and oil, it will likely be ten years before this technology is commonly available. In summary, Li-ion battery technology is going to be the de-facto standard in material handling and ground support equipment in the near future.
In Case of Emergency, Go Swimming?
In a recent Green Cubes webinar, we were asked, “What is the best fire suppression system for lithium-ion batteries?” We are asked this question often by all sorts of customers, whether it be for our lithium-ion material handling, large stationary, or our swappable cart power systems.
Safety is very important to us and our customers, and we want to ensure that everyone is prepared in the case of an unlikely lithium-ion fire. Fires in lithium-ion batteries are often a result of a process called thermal runaway. Thermal runaway is when one hot cell can light the next cell on fire just by getting it hot enough. This is a cascading type of failure where one cell may ignite, and then heat up the cells nearby, and then they ignite, and so on and so forth. This is the primary way fire propagates through lithium-ion batteries. Many battery systems have preventative measures built in to slow down the thermal exchange from cell to cell. This may slow the fire, but it usually doesn’t stop the fire.
The National Fire Protection Association is in charge of constructing U.S.-based best practice documents for building and commissioning of structures to prevent and reduce the risk of fires. There are codes and standards that cover construction, electrical, HVAC and plumbing systems. All NFPA codes are available at NFPA.org, and printed copies are available for purchase. All architects, contractors, engineers and tradesmen must reference these standards as they perform their duties.
Experts spend years researching and creating the NFPA codes. NFPA code 855 was released in 2020 and covers the Installation of Stationary Energy Storage Systems. A 2023 update will cover lithium-ion batteries.
In NFPA 855, Annex C is all about Firefighting Considerations. Here we find that “the NFPA’s Fire Protection Research Foundation and third-party engineering groups have shown that fires involving lithium-ion cells must be cooled to terminate the thermal runaway process.” “Firefighting foams and dry chemicals are not considered to be effective for these chemistries because they lack the ability to cool sufficiently and can conduct electricity.” It’s also noted that Carbon Dioxide and inert gas (such as Halon SF6) are also ineffective at cooling the batteries and cells.
How do we maintain the safety in data centers, hospitals, warehouses, and any other building with lithium batteries inside? What is the best fire suppression system? The simple answer is water, and lots of it, enough to go swimming, and then some! This will cool the cells and stop the thermal runaway process. Water is the agent of choice due to its abundance (in many areas), superior cooling capacity, and ease of transport to the seat of the fire. Water can come from a built-in fire suppression system, or a firefighting hose. In some unique systems where fire poses little to no risk to the surrounding uninvolved equipment the NFPA mentions that a “defensive posture” is to be considered, and the fire left to burn itself out. This is often a good strategy for outdoor cabinet locations that are far from people and other equipment since having water on site might not be possible.
As a further safeguard, the NFPA also limits the amount of energy stored and the density of these batteries to help prevent fire propagation. Section 9.4.1 states that each “rack” of batteries cannot exceed 50kWh and must be spaced at 3-foot intervals. This is to help prevent fire from spreading rack to rack in the case of an event. It also allows for enough room to get fire fighting equipment into the area to douse the fire with lots of water. Finally, most sites are limited to no more than 600kWh of batteries, or 30 of the max “racks” from above. As all NFPA rules, the AHJ (Authority Having Jurisdiction) has the final say on any installation and may require additional safety measures to be in place, such as local fire department training, annual walk throughs, etc.
