LHS (LATENT HEAT SOLUTIONS) Because of their energy density, higher voltage, and negligible memory effects, lithium-ion batteries are the popular choice for a wide range of applications, especially in electric vehicles, energy storage, and portable tools and devices. Larger power demands and increasing cell density of lithium-ion battery packs result in highoperating temperatures, especially under peak loads. Because of the susceptibility of most commercial lithium-ion cell chemistries to degrade or age at or above 60°C, this leads to rapid loss of capacity over subsequent charge/- discharge cycles as well as reduced overall power output. Reducing detrimental thermal effects through the use of Latent Heat Systems (LHS®) materials that absorb and store thermal energy, has proven highly effective. With their high latent heat, ease of processing, and impressive reliability, LHS materials are becoming the forerunner in effective, simple, and economical thermal management designs for power intensive lithium-ion battery applications.
Another impressive feature of LHS Battery Materials is their ability to reduce and even eliminate the potential for Thermal Runaway or Propagation in battery packs. Thermal Runaway and Propagation potential is a growing safety concern in many applications due to the possibility of serious fire in the event the cells are physically damaged or short circuited. The LHS® Battery Materials are highly flame retardant and can eliminate the potential for runaway in a battery pack resulting in a much safer product.

LHS® FILL AND FLOW MATERIALSLHS® materials provide passive energy absorption, thermal mitigation homogeneity, and safety. The LHS Fill & Flow materials may be heated and poured into a sealed environment providing exceptional latent heat properties. These materials are not shape stable.
Latent Heat Solutions (LHS®) thermal management materials provide energy absorption and heat dissipation characteristics for passive thermal control. These materials are designed to prevent thermal runaway, maintain homogenous temperatures across cells and reduce battery overheating due to fast charging/discharging which leads to less battery degradation and an increased battery life.

EXCESSIVE AMBIENT TEMPERATURE ENVIRONMENTSIn many tropical, equatorial or desert areas of the world it is not uncommon to sustain ambient temperatures of 40-50˚C. These excessive temperatures along with battery charging/discharging can easily cause batteries to degrade or perform poorly. LHS® materials can prevent excessive degradation temperatures which leads to longer pack life and reach safe recharge temperatures quicker to allow faster turnover and usage. The graph shows charge/dis-charge results of a standard swappable pack at 40˚C ambient temperature with a 1˚C charge and 2˚C discharge. Charging was commenced when cells where <45˚C.
