In this pursuit of phasing out ICE vehicles, EVs as a trend have been gaining a lot of popularity, where the sector has clocked sales of over 20 lakh units electric vehicles during the financial year 2024-25 as per the Annual India EV Report Card: FY2025 by JMK Research. Gauging the surging demand for electric vehicles, it is essential that the industry focuses on coming up with pioneering technologies to reinforce the performance and offering of the vehicle.
Here, innovating in battery technology can come in handy for expediting the EV adoption process. It can be a game-changer in boosting the prospects of EVs and alleviating the major concerns around the vehicle that deters potential consumers from purchasing the vehicle. The underlying fear of range anxiety coupled with long charging times are major factors dampening the interest of consumers in electric vehicles. Things get further complicated with the incidences of explosions or EVs catching fire that raise a lot of safety issues about the vehicle.
In order to tackle the problems impeding the growth of the sector, the industry is making significant strides at the solid-state Li-ion battery front. Coming with breakthrough advantages as compared to traditional Li-ion batteries, it can fortify EV performance with revitalised power, safety and extended lifespan of batteries. Vouching for next-generation batteries, the solid-state Li-ion batteries contribute to the amplified range of the EVs; thereby, it comes with the ability to drive deeper penetration of EVs across the country.
Unlike traditional Li-ion batteries, the solid-state Li-ion batteries are made up of solid electrolyte which contributes to the great energy density of the batteries. Facilitating increased storage capacity of energy, it is ushering the path for fast charging solutions and maximising the output of vehicles at the same time. The batteries exhibiting advanced technologies are game-changers in alleviating the unique challenges of limited range and slow charging speed of traditional Li-ion batteries.
Delving deep into the advantages of solid-state Li-ion batteries, it is proficient at withstanding extreme temperatures efficiently. This feature comes in handy for abating the major challenges of liquid-state batteries, including ignition of EVs at high temperatures, leading to explosion or fire accidents in the vehicles. In addition to this, the traditional batteries also face the limitation of voltage drop during low temperatures, impeding the performance of the vehicles.
Here, the solid-state Li-ion batteries consisting of non-flammable organic solvents are well equipped to perform at high temperatures and can even resist freezing at low temperatures. By defying high heat temperatures, the solid-state batteries support fast charging that mitigates the long charging hours of liquid-state batteries. Along with this, the solid electrolyte deteriorates at a much slower pace as compared to traditional Li-ion batteries, further boosting the lifespan of the batteries.
Looking at the distinctive advantage of solid-state Li-ion batteries over their liquid counterpart, it mandates the manufacturing of the highest quality batteries for adding to their resilience and efficiency. With solid electrolytes consisting of sulfides, it is highly susceptible to degeneration given the sensitivity of sulfides to even the slightest trace of moisture in the air. As a result, it becomes a prerequisite to provide a highly controlled environment at the time of solid-state Li-ion battery manufacturing.
In order to address the moisture menace, industry players must prioritise installation of desiccant dehumidification technology across the manufacturing facility to control the humidity level with precision. It goes a long way in reducing the effect of moisture on the processes and facilitates efficient handling of moisture-sensitive materials to avoid the manufacturing of any low-quality, defective solid-state Li-ion batteries.
In addition to this, the role of dehumidifiers transcends to providing energy-efficient solutions apart from thoroughly monitoring the humidity levels. Here, it is important to note that solid-state Li-ion batteries are manufactured in Dry Rooms which are huge energy guzzlers, accounting for approximately 43 percent of energy consumption during the process. Therefore, deploying desiccant dehumidifiers comes in handy for achieving the two-fold task of minimising energy utilisation while providing a < -80°C air Dew Point supply. Moreover, employing Bry- Air’s Super Low Dew Point (LDP) dehumidifiers further aids in driving the energy efficiency of the Dry Rooms aimed at reducing the operational costs of manufacturing. Coming with high-performance rotors, the dehumidifiers are adept at contributing to optimal efficiency of Dry Rooms.
In the process of maintaining ideal conditions for solid-state battery manufacturing, the advanced dehumidifiers also attain a -80°C dew point and ensure supply air of < -70°C Dew Point aimed at driving stability and optimal performance of solid electrolytes. To further fortify the manufacturing process, it is of prime importance that industry players focus on deploying NMP recovery technology. It specialises in recycling the hazardous and costly volatile NMP that is produced at the time of manufacturing batteries. The technology plays a crucial role in supplying high-purity NMP solvent that contributes to efficient manufacturing of solid-state Li-ion batteries and also guarantees production of the highest quality batteries that conform to industry standards.
Beyond manufacturing, the NMP recovery technology helps in regulating the NMP released into the air that strictly complies with government regulations. Cumulatively, it curbs air pollution caused at the time of battery manufacturing and also protects the occupants from developing cancer on account of NMP released into the air.
Understanding the critical role of dehumidifiers in solid-state Li-ion batteries, it comes with a lot of potential to give the desired impetus to the EV industry. Steering the high performance of the batteries, it comes in handy for tackling some of the major concerns deterring the purchase of EVs in the market. Exhibiting efficient storage capacity, it empowers the EVs with longer range and reduced charging frequency, addressing the fear of range anxiety, and also ensures the safety of vehicles by alleviating the incidents of EVs catching fire.
Thereby, it can be said that highly advanced desiccant dehumidifiers are at the helm of democratising clean mobility. Achieving pristine environmental conditions driving precision in controlling humidity level and temperature, it delivers highest quality solid state Li-ion batteries for delivering safer and more reliable EVs. Therefore, for giving the desired impetus to EV adoption across the country, industry players must focus on establishing a resilient battery manufacturing infrastructure that comes with the ability to fortify the positioning of the vehicles in automotive sector.
