AllCell Technologies designs and manufactures lithium-ion battery packs for portable, stationary, and transportation applications. Our patented thermal management technology allows production of compact, lightweight, and long-lasting batteries.
AllCell’s passive thermal management technology is based on the use of Phase Change Composite (PCCTM) to surround each lithium-ion cell, absorbing and conducting heat away to dramatically extend the life of the cells and prevent fire or damage to the battery. AllCell’s products avoid the need for expensive, complicated, and inefficient active thermal management systems, replacing pumps, motors, and hoses with an elegant passive system that requires no energy to operate and has no moving parts.
AllCell has created a suite of phase change composite (PCC) thermal materials to improve the safety and performance of lithium-ion battery packs. PCC is a lightweight combination of phase change material and graphite that absorbs and distributes heat. When integrated into a lithium-ion battery pack, AllCell’s phase change composite (PCCTM) provides four key benefits:

The lithium-ion cells in the battery pack are placed in intimate contact with our PCC. As the pack heats up, the graphite spreads the heat evenly throughout the pack, avoiding hot spots and ensuring temperature uniformity. Once the temperature reaches the melting point of the PCC, all additional thermal energy is absorbed by the melting process rather than continuing to raise the temperature.
Even though the PCC is “melting” the composite material itself remains solid even at extremely high temperatures and nothing leaks out. By selecting different base materials, AllCell can control the maximum temperature in each pack to ensure optimal performance.
