An electric shaver (also known as the dry razor, electric razor, or simply shaver) is a razor with an electrically powered rotating or oscillating blade. The electric shaver usually does not require the use of shaving cream, soap, or water. The razor may be powered by a small DC motor, which is either powered by batteries or mains electricity.
The first generation rechargeable alkaline batteries were introduced by Union Carbide and Mallory in the early 1970s. [3] [5] Several patents were introduced after Union Carbide's product discontinuation and eventually, in 1986, Battery Technologies Inc of Canada was founded to commercially develop a 2nd generation product based on those patents, under the trademark "RAM".
With the earned money, he founded Micro Mobility Systems in 1999 and started producing the two-wheeled Scooter, which was an even bigger success. Because of the excessive demand, he allowed his partner in Taiwan to distribute the Scooter in the United States with the name Razor for a commission. After selling about one million Scooters in 2000 ...
A lithium-titanate battery is a modified lithium-ion battery that uses lithium-titanate nanocrystals, instead of carbon, on the surface of its anode.This gives the anode a surface area of about 100 square meters per gram, compared with 3 square meters per gram for carbon, allowing electrons to enter and leave the anode quickly.

The specific energy of LFP batteries is lower than that of other common lithium-ion battery types such as nickel manganese cobalt (NMC) and nickel cobalt aluminum (NCA). As of 2024, the specific energy of CATL's LFP battery is claimed to be 205 watt-hours per kilogram (Wh/kg) on the cell level. [13] BYD's LFP battery specific energy is 150 Wh ...
