Summary
The recent cases of electric scooters catching fire have raised safety
concerns. Sales of electric scooters have surged in the last few
years, but the spate of fire incidents has cast a shadow on the
promising industry. Exploding smartphones are not very common
these days, yet news about them tends to appear from time to time.
In the past, Samsung's galaxy note 7 phones have faced the issue of
battery explosion. Recently, OnePlus's Nord 2 batteries have also
faced battery explosion problem.
Batteries play important role in all electronic devices. In case of
electric vehicles, they are the largest, most expensive, and important
components. Unfortunately, batteries are susceptible to explode
under unfavourable conditions. The government is planning to
introduce new quality standards for batteries used in EVs. Industry
players are also reportedly working on the improvement of tech and
batteries.
This report examines the global market, innovation, & patent filing
trends targeted to fire/explosion proof batteries.

Framework
A dataset of around 3,000+ patent families focusing on
fire/explosion proofing of batteries was obtained using PatBase
database. It was manually analyzed to screen around 2,000+ patent
families. The patent data was analyzed collectively as statistical
data points for the various insights provided in the report. Market
data was collected from various reliable and acceptable sources.
To analyze the dataset, some assumptions were made, including that
the country of first filing generally indicates the country of invention
and that a published application is a good indication of
commercially viable IP. The analysis also took into consideration the
political, legal, and competitive environment. A total effort of 60
hours was spent in conducting and preparing this study report.
Boolean IP strives to ensure the accuracy and comprehensiveness of
studies it conduct. However, because of the subjective nature of
such research, we cannot warrant that our study is 100% complete or
error-free.

The battery industry banks on replacement sales as demand growth is related to service life. Even long-lasting rechargeable secondary
batteries need replacement in the long run. These factors make replacement sales the driving force behind market growth. Another
important factor which of late is influencing demand for batteries is product safety and environmental sustainability. Therefore, it is not
surprising that in the coming years, battery chemistries such as Nickel-cadmium (Ni-Cd), would witness lackluster growth. Lithium-Ion
segment is expected to hold a significant share over the forecast period owing to its high use in several applications, including electric
vehicles, laptops, mobiles, and other appliances.
Looking at the environmental concerns and forecast for battery demands in future, it becomes utmost important to find
solution to Battery Fire/Explosion problems.

IP LEADERS GEOGRAPHICAL PREFERANCES

13. Indian Oil Corporation (IOC) and Israeli battery developer Phinergy formed a joint venture
(JV) on Wednesday to build ultra-lightweight metal-air batteries for electric vehicles (EVs).
The JV will use aluminum to make batteries for EVs instead of lithium so that EV can charge
faster and give a longer run. This will help overcome most of the challenges facing EVs
including range anxiety, higher cost of purchase and safety issues
Dutch automaker Stellantis NV (STLA) and LG Energy Solution have announced plans to
invest about $4.1 billion through a joint venture to build a large scale, domestic, electric
vehicle battery manufacturing facility in Canada. The joint venture company will produce
lithium-ion battery cells and modules to meet a significant portion of Stellantis' vehicle
production requirements in North America.
LG Chem has signed a joint venture agreement with Tianjin B&M Science and Technology,
a subsidiary of China’s Zhejiang Huayou Cobalt to produce affordable and high-quality
cathode materials, a key component in battery manufacturing. With an investment of 403
million dollars from both the partners, LG Chem’s cathode production site in Gumi, South
Korea will be used for the project.
RECENT COLLABORATIONS

14. Faradion was founded in 2011 to develop sodium-ion technology and to bring it to market.
Faradion was the first company of the new Millennium to identify and exploit the potential
of sodium ions in a rechargeable battery. With more patents in this area than competing
Na-ion companies, Faradion can cement it’s position as market leader of non-aqueous
sodium-ion batteries.
Lithiumwerks was founded in 2017. It combines NanoPhosphate technology with
smart software to create safer and more energy efficient batteries for vehicles.
Lithium Werks Lithium Iron Phosphate (LiFePO4) batteries are inherently safer
than other lithium batteries.
NOHMs Technologies, Inc. was established in 2011 in Ithaca, NY from technology
developed at Cornell University. NOHMs develops electrolyte solutions containing a new
functional ionic liquid material that allows for the creation of non-flammable batteries for
electric cars. The company's technological advances, compatible with most anode and
cathode chemistries, have resulted in relationships with industry leaders in electric vehicle,
ESS, and industrial product markets.
STARTUPS DEVELOPING SAFER BATTERIES

15. Startup Cadenza Innovation has worked since 2012 to create a battery in which a
malfunction leads to "a service event instead of a catastrophe," in the words of founder
and CEO Christina Lampe-Onnerud. The company's "supercell" design packs 24 jelly-roll
cells into a fireproof ceramic fiber housing with numerous safety measures to intercept
fires and prevent them from spreading.
Log9 Materials was founded in 2015. Log9 Materials is using its core competence in
Graphene nanotechnology to develop advanced energy storage technologies from
electrode materials, cell to pack level. Its Rapid Charging Battery packs solve the challenges
in adoption for the 2W and 3W electric vehicle platforms. The recyclability of these cells is
extremely high due to inherent resistance of these cells to catch fire or explode.
Gridtential is the creator of Silicon Joule®, breakthrough advanced AGM battery
technology that provides a lower-cost, safer, greener alternative to lithium-ion. Inspired
by solar technology, Silicon Joule dramatically improves power density, discharge rate
and cycle life while reducing weight by 30%, delivering superior performance for deep-
cycle and power applications including personal electric vehicles, renewable energy
storage systems and hybrid automotive.
STARTUPS DEVELOPING SAFER BATTERIES

16. Zelos batteries are based on abundant, inexpensive and low-toxicity materials, which
translates into a 70% cost advantage as compared to lithium-ion for a given amount of stored
energy. Zinc (Zn) has long been considered an ideal battery electrode due to its high power
and energy density, low cost, global availability, environmental characteristics and ease of
recycling. Similarly, manganese (Mn) is an abundant, safe, inexpensive and widely used
element. Zelos’s technology stabilizes both metals and turns them into a fully rechargeable
battery.
Ion Storage Systems, Inc. manufactures high energy density, solid state lithium metal
batteries that are intrinsically safe and require no external heating or compression. ION's
patented battery design is nonflammable, enables fast-charging capabilities, provides wide
operating temperatures, reduces volume and weight of the cells, and is compatible with
current and next generation cathodes, including high voltage cathodes that are nickel and
cobalt-free.
COnovate is a startup that develops lithium-ion battery parts made from a graphene
monoxide that boosts the energy storage capacity. These materials are based on
abundant, non-toxic starting materials that offer low-cost, safer and higher capacity
alternatives to graphite-only anode batteries. Batteries with the patented materials
demonstrate higher capacity and faster charge rates than graphite.
