![]() They find use in passenger vehicles especially for shorter range and lower cost. Given that it uses iron, it is low-cost and safer than other cathode chemistries, but LFP is also heavy and has lower energy capacity. LFP – It is a cathode material composed of lithium, iron, phosphoric acid, and oxygen.This chemistry gives good performance and is relatively safe, but due to the high cobalt content, it is also expensive and therefore, not used in EV applications. On account of its low energy density, it is not often used for batteries in electric vehicles but is widely used in Li-ion batteries for portable electronics like smartphones. LCO – It is a cathode material composed of lithium, cobalt, and oxygen.These five different types of cathode materials are lithium cobalt oxide (LCO), lithium iron phosphate (LFP), lithium manganese oxide (LMO), lithium nickel manganese cobalt (NMC), and lithium, nickel, cobalt, aluminum (NCA). Regardless of the battery chemistry, lithium is required in all cathode materials. The main factor influencing the choice of material are cycle life, energy density, cost and availability of materials, power to energy ratio, safety, and temperature of operation.Īmong the numerous combinations of cathode materials, five combinations have been determined to produce the best performance as a battery. Therefore, there are several materials for the cathode. Further, various cathode materials with different characteristics can be formed depending on the type of metal and proportion used. Lithium, oxygen, and other metals can meet to form various combinations. The battery's capacity and voltage are determined based on what type of active material is used in the cathode. The explosion in breathable-insulation garments has changed the way we think about insulation in the backcountry.Cathode materials in a Li-ion battery are critical as they determine the characteristics of a battery such as its capacity and output. But in an increasingly crowded field, some jackets still rise above. I wore OR’s new Uberlayer Hooded Jacket for numerous days of backcountry skiing-including, at times, as an outer layer while skinning uphill-and as a middle layer skiing downhill both in the backcountry and for hours at a resort And I wore it in temperatures ranging from around freezing to wind chills below zero Fahrenheit, and came away convinced this is a jacket you could legitimately use into the backcountry every month of the year. The first and most obvious measure-and benefit-of puffy jackets with breathable insulation is how much time you spend wearing them rather than carrying them in your pack. In cold temps, on the go, this jacket lived on my back. But the secondary benefit is how this jacket traps heat to keep you from getting chilled after you’ve sweated hard (most likely not wearing the Uberlayer, but in shirtsleeves when pushing hard uphill), while it moves moisture out so efficiently that wearing it over a sweaty base layer allows your body heat to dry out that base layer quickly.įind your next adventure in your Inbox.

So I pulled the Uberlayer on over a middle layer (that had also gotten damp on the climb) for the 20-minute descent by the time I reached my car, my base and middle layers were as dry as when I put them on that morning. ![]() ![]() On long days of alternating between sweating and rapidly cooling down in sub-freezing temperatures, that’s a game changer.Ī few components explain the Uberlayer’s performance. Water-resistant, highly compressible, Polartec Alpha Active synthetic insulation breathes well while trapping warmth. #OUTDOOR RESEARCH UBERLAYER VS CATHODE FREE#Ī breathable, polyester stretch-mesh lining (same as in OR’s Superlayer Jacket) wicks moisture from the inside when you’re producing excess heat that moisture passes through the Alpha insulation and the breathable and highly durable, weather-resistant, nylon stretch-woven shell on the exterior. ![]()
